The answer is a resounding YES—if you do it the right way. This guide will walk you through:
✅ The financial benefits of ADUs

✅ The best ways to finance your ADU
✅ What to watch out for when hiring an ADU contractor
If you’re considering building an ADU in San Diego, here’s why it could be one of the best investments you ever make.
How an ADU Can Add Value to Your Home
1. ADUs Increase Property Value Instantly
A well-built ADU immediately boosts your home’s value by adding square footage, livable space, and income potential.
🏡 Typical Value Increase:
✔ Homes with ADUs in San Diego sell for 25%-35% more than those without.
✔ An 800 sq. ft. ADU can increase home value by $150,000 – $300,000, depending on location and finishes.
✔ Buyers actively seek properties with ADUs, making your home easier to sell at a premium price.
Unlike other home upgrades, ADUs provide a direct return on investment (ROI) while also generating passive income.
2. ADUs Generate Rental Income & Pay for Themselves
San Diego’s rental market is one of the most competitive in the country. The demand for affordable, high-quality rental housing has skyrocketed, making ADUs a prime investment opportunity.
💰 Average Rental Rates for ADUs in San Diego:
✔ Studio ADU: $1,800 – $2,500/month
✔ One-Bedroom ADU: $2,500 – $3,500/month
✔ Two-Bedroom ADU: $3,500 – $5,000/month
At these rates, many ADUs pay for themselves in just 5-7 years while providing a steady income stream long after they’re paid off.
3. ADUs Offer Flexible Living Options
Beyond financial benefits, ADUs provide valuable lifestyle flexibility that homeowners love.
🏡 Common Uses for an ADU:
✔ Aging parents: Keep family close while giving them independence.
✔ Young adults: Provide a space for kids moving back home.
✔ Guest house: Host family and friends with ease.
✔ Home office or studio: A perfect remote work setup.
An ADU adapts to your needs, making it one of the most versatile home additions possible.
Why San Diego Is the Best Market for ADUs
San Diego’s real estate conditions, laws, and demand make it one of the best cities in California to build an ADU.
✅ High Housing Demand: San Diego’s housing shortage means ADUs are in high demand.
✅ Lenient Zoning Laws: California has streamlined ADU approval to encourage new construction.
✅ Strong Rental Market: With limited housing and high rents, ADUs generate premium rental income.
✅ Favorable Climate: Unlike colder states, ADUs in San Diego can have outdoor-friendly designs with patios, decks, and open-air concepts.
If you’re thinking about building an ADU, there has never been a better time to take advantage of San Diego’s ADU-friendly policies.
Best Ways to Finance an ADU in San Diego
Building an ADU doesn’t have to drain your savings. Many homeowners finance their ADUs through smart lending options that allow them to start collecting rental income without large upfront costs.
1. HELOC (Home Equity Line of Credit)
A HELOC lets you borrow against your home’s equity, providing a flexible way to fund your ADU project.
✔ Low interest rates compared to personal loans
✔ You only pay interest on the amount you use
✔ Ideal for homeowners with high home equity
2. Cash-Out Refinance
Refinancing your mortgage at today’s rates can free up cash to fund your ADU, often at a lower rate than personal loans.
✔ Good for long-term investments
✔ Can lower your current mortgage rate
✔ Turns home equity into liquid cash for your ADU
3. Construction Loans & ADU-Specific Financing
San Diego homeowners can apply for specialized ADU loans that fund construction with flexible repayment terms.
✔ Peak Builders & Roofers of San Diego offers financing solutions
✔ ADU-specific loans often require lower down payments
✔ Great for homeowners with less upfront capital
Each financing method has its pros and cons, so it’s crucial to explore options with a trusted lender or contractor.
What to Watch Out for When Hiring an ADU Contractor
Not all contractors are experienced in building ADUs. The wrong contractor can cause delays, budget overruns, and legal issues.
🚨 Red Flags to Watch For:
❌ No ADU experience: ADUs have unique zoning and permit requirements.
❌ Unclear pricing: Beware of low initial quotes that balloon later.
❌ Lack of permits: Unpermitted ADUs decrease home value and can lead to fines.
❌ Poor communication: If a contractor is hard to reach before the project, it only gets worse later.
✅ How to Choose the Right ADU Contractor:
✔ Look for local experience in San Diego ADU construction.
✔ Verify licensing, insurance, and past project reviews.
✔ Ask for a detailed, transparent contract before work begins.
Hiring the right ADU contractor saves you time, money, and headaches while ensuring your ADU meets all legal and safety requirements.
