If you live in San Diego, you’ve probably thought about adding more space to your property. Maybe your family’s growing, or maybe the rising cost of housing has you looking for smart ways to earn extra income. For many, the answer is simple: ADU construction.
As a trusted ADU Contractor in San Diego, we see homeowners every week who want to build something functional, beautiful, and affordable — without the stress of moving or buying another home. You might feel unsure where to start or what’s even allowed, but this guide will help you understand the process clearly. You’ll learn what an ADU is, what the city requires, what it costs, and why working with experienced ADU contractors in San Diego like Ground Up Construction Management Inc. makes the process easier from day one.
What Is an ADU and Why It’s Changing San Diego Living
An ADU, short for Accessory Dwelling Unit, is a small, self-contained home that sits on the same property as your main house. These units can be detached in your backyard, attached to the main home, or created by converting existing spaces like garages.
San Diego’s housing shortage and high property values have made ADU construction one of the smartest investments for local homeowners. A professional ADU Contractor in San Diego can help you design a structure that meets your needs, adds property value, and blends perfectly with your home’s style.
Homeowners across the city — from Pacific Beach to Balboa Park — are turning to ADU contractors in San Diego for a range of reasons:
- Family flexibility: Private living space for parents, adult kids, or guests.
- Rental income: Generate monthly revenue without selling your property.
- Increased value: Properties with ADUs often appraise far higher.
- Lifestyle upgrades: Add a workspace, gym, or guest suite steps from home.
ADUs are transforming how people use their land, and skilled ADU contractors in San Diego are leading that movement.
The City Rules and Permits for ADU Construction
Every city has its own regulations for ADU construction, and San Diego’s are among the most homeowner-friendly in California. The City Planning Department for ADU Construction provides clear guidelines for size, design, and zoning.
Here’s what your ADU Contractor in San Diego will help you navigate:
- Detached ADUs can often be up to 1,200 square feet.
- Junior ADUs (attached to the home) are smaller, about 500 square feet.
- Many parking rules are waived if your property is near public transit or key neighborhoods like Old Town San Diego or North Park.
- You can build both an ADU and a Junior ADU on the same lot.
Professional ADU contractors in San Diego handle all the zoning research, drawings, and permit submissions. At Ground Up Construction Management Inc., we take care of every city submission, including inspections, energy requirements, and design adjustments, so your ADU construction project runs smoothly from start to finish.

The Value of ADU Construction in Different San Diego Neighborhoods
Every neighborhood has a different reason for investing in ADU construction.
- In La Jolla, it’s about adding luxury guest spaces with ocean views.
- In North Park, homeowners create compact rentals to supplement income.
- Around Old Town San Diego, residents maintain classic architecture with historic-style ADUs.

Can You Rent Out Your ADU in San Diego?
Yes, and it’s one of the biggest reasons people choose ADU construction. San Diego allows homeowners to rent out ADUs for long-term stays (30 days or more). Short-term vacation rentals are restricted, which makes ADUs ideal for stable monthly income.
Before you rent, your ADU Contractor in San Diego can ensure your build meets all local codes for rental occupancy, utilities, and accessibility. This step is often missed by inexperienced builders — but seasoned ADU contractors in San Diego make sure your property is ready for tenants from day one.
Keep stucco in good shape
Staying proactive with repairs may feel like an extra chore, but it pays off in a big way. Stucco that’s handled with care can last for decades, while neglected stucco can lead to wood rot, black mold, or structural damage. A routine check once a year, quick patch jobs, and professional inspections form the backbone of smart maintenance.
Here’s a quick recap:
- Inspect your stucco annually for cracks or stains.
- Pay special attention to local climate challenges like salt air or heavy rain.
- Know what your insurance covers, and handle minor issues quickly.
- Decide whether you need repairs or a full replacement based on age and extent of damage.
- Keep up with small preventative measures like trimming vegetation and cleaning gutters.
- Schedule a professional inspection when in doubt.
