Understanding ADU Rental Income: The Ultimate Guide
That charming little cottage in your backyard could be your ticket to financial freedom. ADU rental income is the money you can generate by renting out an Accessory Dwelling Unit on your property, and it’s becoming a game-changer for homeowners across the country.
If you’re wondering what kind of cash we’re talking about, the national average sits at about $1,940 per month for a standard 600 square foot ADU. In high-demand markets like San Diego, that number jumps to around $2,600 monthly, while Los Angeles homeowners are pocketing between $2,000-$2,500 each month.
For those in prime locations willing to explore short-term rental options, the numbers get even more exciting – think $3,500-$5,000 monthly in tourist-friendly areas. And here’s the really good part: well-planned ADUs in hot markets can approach a 10% return on investment. Not too shabby for a structure that fits in your backyard!
“A detached ADU in a high-demand area can yield nearly 10% ROI with smart planning and budgeting,” says industry expert Bar Zakheim. This return often beats traditional rental properties while requiring less headache-inducing management.
Your potential income isn’t just about location, though that’s certainly important. The size and layout of your ADU matter (separate bedrooms command higher rents), as does your rental strategy (long-term vs. short-term). Modern amenities like in-unit laundry and private outdoor space can boost your rates significantly, while local regulations might restrict certain rental terms or require you to live on the property.
Interestingly, today’s rising interest rates have actually improved the ADU landscape by driving up rental demand as fewer people can afford to buy homes. That means more potential tenants looking for quality rental options like your ADU.
One practical tip before you start counting that rental income: set aside 1-3 months of vacancy reserves. This ensures you can cover your mortgage during tenant transitions and sleep better at night.
Why You Need a Proven Formula
Let’s be honest – calculating potential ADU rental income isn’t something you want to guess at. With inflation pushing costs higher every day, having a reliable method to crunch these numbers isn’t just helpful—it’s absolutely necessary.
Housing costs continue their relentless climb nationwide, making ADUs increasingly attractive both for homeowners looking to offset their mortgage and renters desperate for affordable options. It’s a rare win-win in today’s housing market.
“We don’t necessarily like to see high rents—we got into the ADU business to create more affordable housing and help ease the crisis!” says Lynette Padwa, an ADU specialist. Her sentiment reflects the beautiful duality of ADUs: they create income for homeowners while simultaneously expanding the housing supply.
House hacking has become the strategy of choice for many first-time homeowners in expensive markets like San Francisco, Los Angeles, and San Diego. By living in your main house while renting out your ADU (or vice versa), you can make homeownership feasible in places where it otherwise might not be – without having to purchase a duplex or larger multi-family property.
With the five calculation methods we’re about to explore, you’ll be equipped to set realistic rental rates that attract quality tenants while avoiding the pitfalls of underpricing. You’ll be able to project your return on investment with confidence, plan for ongoing expenses, and determine if your ADU project truly makes financial sense before breaking ground.
Perhaps most importantly, you’ll have the documentation needed to qualify for financing that considers rental income – a crucial factor when convincing lenders to fund your ADU project.
Now, let’s roll up our sleeves and explore these proven methods for calculating your ADU rental income potential. Your path to passive income is just getting started.
Way 1 – The Quick “1% Rule” & Rent-per-Square-Foot Check
When you’re first exploring the potential of ADU rental income, you need a quick way to determine if your project makes financial sense. That’s where the 1% rule comes in—a tried-and-true method that real estate investors have relied on for generations.
This simple rule of thumb suggests that your monthly rent should equal approximately 1% of your total project cost. So if you invest $200,000 in building your ADU, you should aim to collect about $2,000 in monthly rent. It’s beautifully straightforward!
Meanwhile, the rent-per-square-foot approach offers another angle by examining what people typically pay in your neighborhood based on living space. This method often gives you a more location-specific estimate.
| Method | Formula | Example for 600 sq ft ADU | Pros | Cons |
|---|---|---|---|---|
| 1% Rule | Project Cost × 0.01 | $200,000 × 0.01 = $2,000/month | Quick, simple calculation | Doesn’t account for location specifics |
| Rent per Sq Ft | Area × Local Rate | 600 sq ft × $3.50 = $2,100/month | Adjusts for local market | Requires current market data |
The good news? ADUs typically command higher rent per square foot than standard apartments. Why? They offer more privacy, often include dedicated outdoor space, and frequently come with perks like private parking that apartment dwellers can only dream about.
How to Apply the 1% Rule
Putting the 1% rule to work for your ADU isn’t complicated, but you do need to be thorough about calculating your total project cost.
Start by adding up all your expenses: design fees, permits (which can be substantial in California!), site preparation, actual construction, utility hookups, landscaping, and even furnishings if you’re offering a furnished unit.
One common mistake? Including your property’s land value. Since you already own the land, leave that out of your calculations. However, do add a 10-15% contingency buffer—construction projects have a funny way of costing more than expected.
Once you have your total, simply multiply by 0.01. For a modestly appointed 500 sq ft ADU costing $180,000:
$180,000 × 0.01 = $1,800 target monthly rent
This quick calculation can tell you in minutes whether your ADU dreams align with market realities before you invest in detailed planning.
When the 1% Rule Fails
While handy, the 1% rule isn’t foolproof, particularly in certain markets. As one of our clients in San Francisco finded: “The 1% rule suggested I should charge $3,200 for my ADU, but nobody would pay more than $2,800 in my neighborhood, despite the housing shortage.”
The rule tends to break down in:
High-cost markets like San Francisco, Los Angeles, and San Diego, where construction expenses are stratospheric but rents don’t necessarily keep pace.
Luxury ADUs featuring quartz countertops, heated floors, and smart home systems that drive up construction costs without proportionally increasing what renters will pay.
Rent-controlled areas where local ordinances may cap what you can charge regardless of your investment.
Rural communities where both construction costs and rental demand tend to be lower than urban centers.
In these situations, the rent-per-square-foot method often yields more realistic projections. Do your homework by researching comparable rentals specifically in your neighborhood—not just your city—and calculate their per-square-foot rates.
As a San Diego homeowner shared with us: “I built a 750 sq ft detached ADU for $348,000. The 1% rule suggested I should charge $3,480 monthly, but market research showed the maximum I could get was $2,900. I’m glad I checked before setting my expectations too high.”
These quick calculations are just your starting point. They’ll help you determine if your ADU project deserves further investigation before you commit significant time and resources.
Way 2 – Leverage Data-Driven Rent Estimators
Gone are the days of guesswork when estimating your ADU rental income. Today’s digital landscape offers powerful tools that crunch thousands of data points to give you remarkably precise rental estimates for your specific neighborhood.
These smart platforms don’t just look at basic metrics like square footage. They analyze everything from seasonal rental patterns to the value of specific amenities in your zip code. Some even use artificial intelligence to forecast future rental trends, helping you make decisions that will maximize your income for years to come.
When I spoke with ADU owners across California, many mentioned how surprised they were by the impact of seemingly small details. One San Diego homeowner finded that offering a furnished unit boosted her rental income by nearly 20% in her beach-adjacent neighborhood—information she wouldn’t have known without these data tools.
Some of the most reliable platforms for ADU rental estimates include:
Rentometer stands out as a user-friendly option that quickly compares your potential rent against nearby similar units. Zillow’s Rent Zestimate leverages their massive database to provide estimates based on their proprietary algorithm. If you’re considering the short-term rental route, AirDNA offers specialized analysis specifically for vacation and short-term stays, showing you potential nightly rates and occupancy projections.
Other valuable resources include Apartments.com for viewing comparable units in your immediate area and Rentrange for detailed rental analysis reports that dive deep into market trends.
Step-by-Step With Online Calculators
Getting accurate results from these platforms requires a methodical approach. Start by entering your precise location—even a difference of a few blocks can significantly impact rental rates in many neighborhoods.
Be thorough when describing your ADU. Beyond the basics of square footage and bedroom count, specify unique features like a private entrance, dedicated parking space, or in-unit laundry. These details can substantially affect your ADU rental income potential.
“I finded my detached ADU could command a $275 monthly premium over a similarly-sized basement unit simply because of the privacy factor,” shared a Portland homeowner. “The online calculator highlighted this difference when I adjusted the unit type from ‘basement apartment’ to ‘detached cottage.'”
When using these tools, try to filter specifically for ADUs, guest houses, or in-law units when possible. This gives you a more accurate comparison than looking at apartment complexes or larger rental homes.
Don’t stop at one estimate—cross-reference results from multiple platforms. Most offer basic estimates for free, with more detailed reports available for a small fee. This investment can pay for itself many times over by helping you set the optimal rental rate.

Validating Online Results Offline
Digital tools provide excellent starting points, but nothing beats boots-on-the-ground research to confirm those estimates. Take a Sunday afternoon to drive around your neighborhood and note any “For Rent” signs. A quick call to inquire about rates can provide valuable real-time market intelligence.
Local landlord forums and Facebook groups often discuss rental rates candidly, offering insights you won’t find in formal listings. One Berkeley homeowner told me: “The online calculators suggested $2,100 for my ADU, but after joining a local landlord group, I learned units with yards like mine were getting $2,400. That inside knowledge boosted my income by $3,600 annually!”
If you’re near a university or hospital, check their bulletin boards for rental listings. These institutions often attract tenants looking for medium-term rentals, which can be an ideal sweet spot between the higher maintenance of short-term rentals and the potentially lower rates of annual leases.
Property managers who specialize in smaller rentals can also provide valuable perspective. They see dozens of similar units and know exactly what features command premium rates in your specific area. A quick consultation could reveal that spending an extra $2,000 on a kitchen upgrade might yield an additional $150 monthly in rent—paying for itself in just over a year.
Online tools, while sophisticated, can’t capture every nuance of your local market. The most successful ADU landlords combine digital insights with old-fashioned neighborhood research to find that rental rate sweet spot that attracts quality tenants while maximizing their return on investment.
Way 3 – Master the Comparable Market Analysis for ADU Rental Income
A Comparable Market Analysis (CMA) is the gold standard for determining rental rates. While real estate agents typically perform CMAs for home sales, you can adapt this approach specifically for calculating ADU rental income with impressive accuracy.
Think of a CMA as detective work – you’re gathering evidence from similar properties to build a case for what your ADU is truly worth. This method shines for ADUs because they often have unique characteristics that automated tools simply miss. That garden-facing entrance or sound-insulated walls might be worth more than algorithms realize!
Picking True Apples-to-Apples ADU Comps
Finding genuine ADU comparables takes some legwork, but the accuracy is worth it. I always tell clients to focus first on property type – an apartment in a fourplex isn’t the same as a backyard cottage with private entrance.
“Privacy is probably the most important aspect to both you and your renters,” notes one ADU specialist I interviewed. This privacy factor often allows ADUs to command higher per-square-foot rents than apartments in multi-unit buildings.
When hunting for true comparables, match your unit in square footage (within 100-150 sq ft), bedroom/bathroom count (exact matches are best), and age/condition. Location matters tremendously – stay within a half-mile radius when possible. Don’t forget parking situations and utility arrangements, as these significantly impact perceived value.
For converted garages or basement ADUs, be sure to compare with similar conversion units rather than purpose-built detached ADUs. The latter typically command higher rents due to better privacy and natural light. I’ve seen detached units fetch $200-300 more per month than converted spaces of the same size simply because of the privacy factor.
Adjusting for Amenities & Restrictions
Once you’ve found comparable ADUs, it’s time for the fine-tuning. Each difference requires a dollar-value adjustment to arrive at your ideal rate.
In-unit laundry is a game-changer, typically adding $75-150 monthly to your ADU rental income. Private outdoor space – even just a small patio – can add $50-200 depending on your market. Dedicated parking spots are gold in urban areas, worth $50-150 per month.
One Los Angeles homeowner shared this brilliant hack with me: “I added a hedge wall between my house and the ADU for just $800, which created a private outdoor space for the tenant. This simple addition allowed me to charge $150 more in monthly rent—it paid for itself in less than six months.”
Don’t forget to account for newer appliances ($25-75 boost), smart home features ($25-50 value), and additional storage space ($25-100 premium). These small touches can significantly impact your bottom line.
Regulatory restrictions also affect your rental value. Many California jurisdictions have 30-day minimum stay requirements that limit your pool of renters. Owner-occupancy requirements, rent control policies, and HOA restrictions can all dampen potential income. Be sure to factor these limitations into your calculations.
The local market dramatically impacts these adjustment values. In tight rental markets like San Francisco or San Diego, premium features command higher adjustments than in markets with more abundant housing. A private entrance in downtown San Francisco might be worth twice what it would command in a suburban setting with naturally more privacy.
By mastering the CMA approach, you’ll have the most accurate, market-based estimate possible for your ADU rental income – giving you confidence in your investment decisions and helping you maximize returns without overpricing your unit.
Way 4 – Use the Lender’s 75% Formula & Agency Guidelines
If you’re planning to use ADU rental income to qualify for a mortgage or refinance, understanding how lenders calculate this income is crucial. Mortgage agencies have specific formulas and documentation requirements that provide another practical way to estimate realistic rental income.
The three major mortgage agencies each have their own approach to ADU income. Fannie Mae only allows ADU rental income under their HomeReady® program, while Freddie Mac is more flexible, permitting ADU rental income across all their mortgage loan programs. FHA takes a middle ground, allowing ADU rental income as part of their ‘Effective Income’ calculation, but caps it at 30% of your total monthly income.
Even if you’re not seeking financing right now, these guidelines offer a conservative, market-tested approach to estimating your potential rental income. Think of them as the “reality check” method – if your projections pass the lender test, you’re probably on solid ground.
Calculating Qualifying ADU Rental Income
The standard calculation most lenders use is refreshingly straightforward:
Qualifying Rental Income = Signed Lease Amount × 75%
This 75% factor isn’t arbitrary – it’s designed to account for those inevitable vacancy periods and ongoing maintenance costs. For example, if your tenant signs a lease for $2,000 monthly rent, lenders would count $1,500 as qualifying income.
There are some additional guardrails to be aware of. Freddie Mac and FHA both cap ADU income at 30% of your total qualifying income. This prevents you from becoming overly dependent on rental income that might fluctuate. Most lenders will also require you to have 2-3 months of PITI (Principal, Interest, Taxes, Insurance) reserves when using rental income to qualify.
“The first time I refinanced with my ADU income, I was surprised by how conservative the lender’s calculations were,” shares Maria from San Diego. “But looking back after five years of being a landlord, that 75% figure was pretty spot-on when accounting for maintenance and the occasional vacancy.”
If you don’t have a signed lease yet, don’t worry. Lenders typically accept a Form 1007 (Comparable Rent Schedule) completed by an appraiser, a market rent analysis from a qualified appraiser, or Schedule E from your tax returns if you’ve previously reported rental income.
For more detailed information about using ADU rental income for mortgage qualification, visit our guide on Fannie Mae ADU Rental Income.
Documentation & Appraisal Must-Haves
When using the lender’s formula, certain documentation requirements provide another framework for validating your rental income estimates. These requirements aren’t just red tape – they highlight important factors that affect your income potential.
First, both Fannie Mae and Freddie Mac prohibit appraisal waivers (sometimes called ACE waivers) for properties with ADU rental income. This means a human appraiser must physically inspect your property – no automated valuations allowed.
Your appraisal will need to include at least one comparable sale with an ADU and at least three comparable rentals, including one with a rented ADU. The appraiser will also need to provide a detailed ADU description covering condition, square footage, and room count.
Legal compliance is another crucial element. You’ll need confirmation that your ADU complies with local zoning regulations, documentation of legal non-conforming status if applicable, and evidence of proper permitting. This is actually a good thing – a non-permitted ADU might generate rental income now but could face legal challenges later, affecting your long-term income stability.
Some lenders, following Freddie Mac guidelines, even require borrower participation in landlord education unless you have prior property management experience. This might seem like an extra hoop to jump through, but it can provide valuable insights for first-time landlords.
According to Freddie Mac’s Guide Policy, lenders must verify that ADUs comply with local zoning and land-use requirements before underwriting rental income. These requirements aren’t just about jumping through hoops – they’re designed to ensure your ADU rental income will be sustainable over the long term.
“The documentation process for my refinance seemed excessive at first,” admits Tom from San Jose, “but gathering those materials actually helped me identify a few issues with my ADU that I needed to address anyway. The process made me a more knowledgeable property owner.”
Way 5 – Full ROI, Cash-on-Cash & Payback Analysis
For the most comprehensive evaluation of your ADU rental income potential, a full Return on Investment (ROI) analysis provides the clearest picture of long-term profitability. This approach goes beyond simple monthly rent calculations to examine how your investment performs over time.
When homeowners ask me about ADU profitability, I always recommend looking at the complete financial picture. A proper ROI analysis considers your initial investment costs, financing terms, ongoing expenses, tax implications, appreciation potential, and the time value of money – all crucial factors that simple rent calculators miss.
Let me share a real-world example from a San Diego homeowner who built a 750 sq ft detached ADU:
This homeowner invested $348,000 total, financing $330,000 at 8% interest (creating $29,057 in annual interest) and paying $18,000 out-of-pocket. Their ADU generates $3,500 monthly ($42,000 annually) in gross rent. After accounting for maintenance and vacancy losses of $4,200 (10% of gross rent) and a property tax increase of $3,480, their net annual income reaches $34,320. This creates a calculated ROI/Cash-on-Cash Return of 9.86% – impressively close to the 10% benchmark many seasoned real estate investors target.
Building the Pro-Forma
Creating your own comprehensive ADU rental income analysis isn’t complicated, but it does require attention to detail. Start by building a pro-forma that captures the complete financial picture:
Revenue projections form the foundation of your analysis. Calculate your base rent (which varies depending on whether you choose long-term or short-term rental strategies), plus any additional income from utility reimbursements if your ADU is separately metered. Some homeowners also charge extra for parking spaces or storage areas.
Financing costs significantly impact your bottom line. Include your monthly principal and interest payments, loan origination fees spread over time, and understand how your interest rate affects cash flow. Even a 1% difference in your rate can substantially change your returns.
Don’t forget operating expenses – they’ll eat into your profits if not properly accounted for. Your property taxes will likely increase (typically 1-2% of the ADU value annually), as will your insurance premiums. Set aside 5-10% of gross rent for maintenance and another 5-8% for vacancy allowance. If you’re not self-managing, budget 8-12% for property management. And remember to include utilities if they’re built into the rent.
“Well-designed ADUs maximize rental income and address housing demand with style and functionality,” notes industry expert Bar Zakheim. This is why thoughtful design elements that boost rental appeal should be part of your ROI analysis from the start.
Tax considerations can significantly improve your bottom line. Your ADU qualifies for depreciation benefits (typically over 27.5 years), and you can deduct mortgage interest, property taxes, and maintenance expenses. Just be aware of passive activity loss limitations that might affect how you can use these deductions.
Finally, look into special incentives that might boost your returns. Solar tax credits, energy efficiency rebates, and local ADU incentive programs can all improve your financial picture.
For more insights on controlling costs while maximizing rental potential, see our guide on ADU Construction Cost.
Interpreting Your ROI
Once you’ve built your pro-forma, focus on these key metrics to understand your investment’s performance:
Your Cash-on-Cash Return (annual net cash flow divided by your out-of-pocket investment) tells you how efficiently your initial investment is working for you. The Cap Rate (annual net operating income divided by total project cost) helps you compare your ADU investment to other potential real estate opportunities. Your Payback Period shows how long it takes to recoup your initial investment, while the Internal Rate of Return (IRR) provides the annualized effective compounded return rate.
The 9.86% ROI in our example above is considered excellent in today’s market. For context, a 5-7% ROI is generally considered good performance, 8-10% is excellent, and anything above 10% is outstanding (typically requiring favorable financing or exceptional market conditions).
Your payback period will vary based on financing terms and local market conditions. In high-demand areas like the San Francisco Bay Area or Los Angeles, ADUs typically achieve payback within 5-7 years when considering both cash flow and property value appreciation.
A Mountain View homeowner recently shared her success story with me: “My ADU cost $280,000 to build in 2019. It rents for $2,800 monthly and has increased my property value by an estimated $400,000. Between the rental income and appreciation, it’s been my best investment by far.”
Your financing terms significantly impact returns. A seemingly small 1% difference in interest rate can change your cash-on-cash return by 1-2 percentage points – the difference between a good investment and a great one.
Frequently Asked Questions About ADU Rental Income
How much can a 600 sq ft ADU earn monthly?
Wondering what you might earn from your backyard cottage? The national average for a 600 sq ft ADU sits around $1,940 per month for long-term rentals. But location changes everything!
In coastal California cities, your earning potential jumps significantly:
– Los Angeles homeowners typically collect $2,000-$2,500 monthly
– San Diego ADUs command $2,200-$2,800 each month
– San Jose units bring in $2,200-$2,700
– San Francisco tops the list at $2,500-$3,200 monthly
The short-term rental market shows even more dramatic variations. That same cozy ADU might fetch $100 nightly in Portland, while a similar space in Santa Monica could command a whopping $300+ per night during peak seasons.
“The best estimates come from multiple sources,” explains one ADU investor. “I ran all five calculation methods from this article and found they converged around $2,400 for my San Jose unit – which is exactly what I’m earning now.”
Your specific amenities, finishes, and even your property’s privacy features will influence your final numbers. The multiple calculation methods we’ve covered give you the tools to triangulate your most accurate estimate.
Can I count ADU rent to qualify for a mortgage?
Yes! ADU rental income can help you qualify for a mortgage, though each lending agency has their own specific guidelines:
Fannie Mae is the most restrictive, allowing ADU income only through their HomeReady® program. Freddie Mac is more flexible, permitting ADU rental income across all their mortgage products. FHA takes a middle ground, allowing you to use this income but capping it at 30% of your total monthly qualifying income.
All three agencies apply what I call the “reality check” factor – they’ll only count 75% of your lease amount toward qualifying income. This built-in buffer accounts for potential vacancies and unexpected expenses.
“When I refinanced last year, my lender required extensive documentation,” shares one Oakland homeowner. “But the effort was worth it – my ADU’s income helped me qualify for a much better rate.”
Documentation requirements typically include a signed lease (the gold standard), a Form 1007 Comparable Rent Schedule, or Schedule E tax forms if you’ve previously reported rental income. Importantly, you can’t get an appraisal waiver when using ADU income to qualify – the appraiser must physically inspect the unit and provide comparable ADU rentals.
What taxes and deductions apply to ADU rental income?
The tax implications of your ADU rental income might seem daunting at first, but understanding them can significantly boost your effective returns.
You’ll generally report this income on Schedule E of your tax return. How exactly you report depends on your ownership structure – through an LLC it’s operating income, while sole proprietors report it as earned income. The IRS wants to know about all your rental income, whether your tenant stayed for a year or just a weekend.
The good news? Your deductions can substantially offset this taxable income. Most ADU landlords can deduct mortgage interest on their construction loans, the portion of property tax attributable to the ADU, and depreciation (typically calculated over 27.5 years). Day-to-day expenses like maintenance, repairs, insurance premiums, and utilities you pay are all deductible too.
Don’t forget about professional services! Property management fees, accounting costs, and even travel expenses related to managing your rental can reduce your tax burden.
“The depreciation deduction alone saved me over $5,000 in taxes last year,” notes a San Diego ADU owner. “My accountant’s fee was the best $300 I spent all year.”
One important caveat: rental activities generally fall under “passive activity” limitations. This means passive losses may only offset passive income unless you qualify as a real estate professional. However, if your modified adjusted gross income is under $100,000, you may deduct up to $25,000 in passive losses – a significant benefit for many homeowners.
Tax implications can dramatically impact your effective return, so consider consulting with a tax professional who specializes in rental property taxation. The right guidance can make a substantial difference in your bottom line.
Conclusion
Calculating your ADU rental income accurately isn’t just about crunching numbers—it’s about creating a financial foundation for one of the most significant investments you’ll make on your property. Throughout this guide, we’ve explored five powerful methods that together provide a comprehensive picture of your ADU’s income potential.
Think of these calculation methods as different lenses for viewing the same landscape. The 1% Rule gives you that quick first impression, while detailed ROI analysis reveals the long-term terrain. Online estimators provide the data-driven perspective, while the comparative market analysis grounds everything in local reality. And if you’re planning to use that rental income for mortgage qualification, the lender’s formula ensures you’re speaking the same language as financial institutions.
I’ve worked with homeowners who were shocked to find their ADU could generate nearly 10% ROI in high-demand neighborhoods—far outperforming many traditional investments. But this kind of return doesn’t happen by accident. It comes from careful planning and accurate projections from the start.
The most successful ADU investors:
Use multiple methods to verify their income projections. When three different approaches point to similar rental rates, you can move forward with confidence.
Think strategically about rental terms early in the planning stage. The layout that works beautifully for a long-term tenant might leave money on the table if you’re in a prime short-term rental location.
Account for all expenses in their calculations. That gorgeous rental income looks a lot different after you’ve set aside funds for maintenance, property taxes, and those inevitable vacancy periods.
Keep meticulous documentation if they plan to leverage rental income for financing. Those extra steps during planning can make all the difference when you’re sitting across from a mortgage underwriter.
Stay updated on local regulations that might affect everything from rental terms to occupancy requirements. The regulatory landscape for ADUs continues to evolve, especially in California.
Here at ADU Marketing Pros, we’ve had the privilege of helping countless builders and architects across California’s hottest markets—from San Francisco to Los Angeles to San Diego—communicate the real income potential of their projects.
