Why Build an ADU in San Diego?
Rising Housing Demand & Cost of Living
San Diego’s real estate market is competitive, and the cost of housing keeps climbing. For many families, moving to a larger home just isn’t practical—or affordable. Building an ADU allows you to maximize the property you already own without the hassle of relocating. Whether you use it as a private office, a rental unit, or extra living quarters, an ADU is a cost-effective way to expand your options in a tight housing market.
Rental Income Opportunities
One of the most appealing benefits of an ADU is the potential for steady rental income. San Diego has strong demand for rentals thanks to its universities, medical centers, and thriving tourism industry. Homeowners can rent their ADU to long-term tenants, traveling nurses, military families, or even list it on platforms like Airbnb or Vrbo. This additional income can help pay down your mortgage, cover property taxes, or simply give you more financial freedom.
Flexible Space for Family
ADUs are also incredibly practical for families who want to stay connected while maintaining independence. Many homeowners use them as in-law suites for aging parents, private spaces for adult children moving back home, or comfortable guest houses for visiting friends and relatives. Instead of feeling crowded inside the main house, everyone gets their own privacy while still staying close by. The best part? As your family’s needs change, your ADU can easily adapt.
Boosting Long-Term Property Value
An ADU isn’t just useful in the present—it’s also a long-term investment. Properties with ADUs often see higher resale values because buyers recognize the potential for income and added functionality. In many cases, homes with ADUs not only sell for more but also move faster on the market. For San Diego homeowners, that means building an ADU is a smart way to protect and grow the value of their largest asset.
Lifestyle Freedom & Flexibility
Beyond income and value, ADUs give you freedom. They can double as a home office, art studio, gym, or private retreat away from the main house. Many San Diego residents are working remotely or running businesses from home, and an ADU provides a dedicated space without the distractions of the main household.
Adding an ADU to your property is largely to improve your living conditions but also for financial support, customization, and sustainability. This enhancement to property value takes community living to new heights. An ADU is an eco-smart investment that enhances one's life at all times. At Harmony Design and Build, we’re excited to help you explore the possibilities and bring your ADU vision to life in sunny San Diego, CA!
Types of ADUs We Build
Detached ADUs (Backyard Homes)
Detached ADUs are standalone units built in your backyard. Think of them as a small home with their own entrance, kitchen, and bathroom. They’re ideal if you want to rent out the unit, create a private guest house, or give family members their own space while still being nearby. Detached ADUs give the most flexibility and independence since they don’t share walls with your main house.
Attached ADUs
An attached ADU is built as an extension of your existing home, often connected through a shared wall. These are great for homeowners who want more living space without the full expense of a detached build. They work perfectly as extra bedrooms, home offices, or in-law suites and often blend seamlessly into your existing floor plan.
Garage Conversions
For a more natural, upscale look, stone retaining walls are hard to beat. They blend seamlessly with landscaping and give your yard a timeless, elegant feel. While stone walls can be more of an investment, they add incredible curb appeal and are perfect for San Diego homeowners who want their yard to feel like a luxury outdoor retreat.
Custom ADU Designs
Every property is unique, which is why custom ADUs are such a popular option. With a custom design, you’re not limited to standard layouts—you can build exactly what you want, whether that’s a two-story unit, a backyard office, or a rental property that maximizes your lot size. Custom ADUs are tailored to your property’s slope, style, and zoning rules, giving you a one-of-a-kind living space.

🧰 Accessory Dwelling Unit (ADU) FAQs
❓ How much does it cost to build an ADU in San Diego?
Answer: The cost depend on the type of ADU. Garage conversions tend to be the most affordable, while detached, custom-built units cost more. Materials, finishes, and site conditions also play a big role in pricing.
❓ What are the ADU permit requirements in San Diego?
Answer: In San Diego, most single-family and multi-family properties can build an ADU. Permits are required, and the city has specific rules on size, setbacks, and height. The good news is that California has relaxed ADU laws to make building easier, and our team handles all the paperwork and approvals for you.
❓How long does it take to build an ADU in San Diego?
Answer: On average, building an ADU takes 3 to 4 months from start to finish. The timeline includes design, permitting, and construction. Prefab ADUs can be completed faster since much of the work is done off-site.
❓ How long does a retaining wall last?
Answer: A properly built retaining wall can last anywhere from 20 to 50 years or more, depending on the material and maintenance. Stone and reinforced concrete walls often last the longest, while timber walls may need replacing sooner. With regular care and proper drainage, you can maximize the life of your wall.
❓ Can I build an ADU on my property in San Diego?
Answer: In most cases, yes. If you own a single-family home, you’re typically allowed at least one ADU and possibly a Junior ADU (JADU). Multi-family properties may be able to add multiple ADUs. A quick property evaluation can confirm your eligibility.
❓ Can I rent out my ADU in San Diego?
Answer: Yes, you can rent your ADU for long-term housing, and many homeowners do so to earn steady monthly income. Short-term rentals like Airbnb may have additional rules depending on your neighborhood or HOA, so it’s best to double-check.
❓ What is the difference between a granny flat and an ADU?
Answer: They’re essentially the same thing. “Granny flat” is just an older term that people use, while ADU (Accessory Dwelling Unit) is the official name used by the city and state. Both refer to a secondary living space on your property.
❓ How do I choose the right ADU builder in San Diego?
Answer: Look for a builder with local experience, proper licensing, and a design-build process that covers everything from permits to construction. Reviews, portfolios, and transparency with pricing are also key. The right builder should make the process smooth and stress-free.
