Questions
Bay Park & Clairemont questions.
Why are Bay Park and Clairemont good ADU neighborhoods?
Three reasons: the lots are generally flat and regular, the rear yards are deep enough to place a detached unit without fighting the site, and most of the area is outside the coastal overlay, so the permit path is typically simpler than it would be in La Jolla or Point Loma. It is also the neighborhood we live in and work in most.
How much does an ADU cost in San Diego?
Most detached ADU builds in San Diego County currently run between $100,000 and $400,000, with $300,000 being a common average for a turnkey standalone unit. Many homeowners assume high-end countertops or tile drive the budget up; in reality site conditions move the final number far more than finish selections do. The major variables are almost always below the surface: utility extensions (trenching and connecting separate water, sewer, and electrical lines), site work and grading on sloped coastal lots or tough soil, and the structural foundation engineering a detached unit requires. Ranges reflect verified San Diego building metrics as of September 2026.
What types of ADU can I build?
There are four common paths: a detached ADU built new in the rear yard, an attached ADU that shares a wall with the house, a garage conversion that reuses the existing structure, and a junior ADU created inside the existing footprint of the home. Which one fits is decided by the lot, the setbacks, and what is already standing on it.
Do I need a permit to build an ADU in San Diego?
Yes. An ADU requires a building permit, and depending on the parcel it can also require additional review. Properties inside a coastal overlay zone typically need a coastal development permit on top of the building permit. Which agency issues it depends on the city: City of San Diego neighborhoods go through Development Services, while Del Mar, Encinitas, and Carlsbad run their own departments.
How long does it take to build an ADU in San Diego?
Building an accessory dwelling unit (ADU) in San Diego typically takes 6 to 18 months from initial concept to completion. While partnering with San Diego Coastal Builder streamlines the process, your actual timeline depends on your ADU type and the city’s current permitting backlog.
Here is what the typical timeline looks like when working with a GC:
- Phase 1: Design & Engineering (2–4 months): Finalizing your layout, drafting structural engineering plans, and selecting interior finishes.
- Phase 2: Permitting & Approvals (2–8 months): Navigating city plan checks. While California aims for a 60-day review timeline, local backlogs and structural revision rounds often extend this phase.
- Phase 3: Construction (2–6 months): Groundbreaking, utility tie-ins, framing, interior finishes, and final inspections.
What size lot do I need and how large can they be?
There is no minimum lot size requirement to build an ADU in San Diego.
Thanks to California state laws, you can legally build an ADU regardless of how small your lot is, as long as it is located on a residential property with an existing or proposed home.
While you do not need a massive yard, the usable space on your lot determines the maximum size of your ADU:
1. The 800-Square-Foot State Guarantee
California law features an “override rule” protecting small properties. Local cities cannot enforce strict zoning restrictions, such as lot coverage limits or floor area ratios, if those limits prevent you from building a detached ADU of at least 800 square feet. If it physically fits within the setback boundaries, you are legally allowed to build it.
2. Setback Requirements (The True Limitation)
Instead of lot size, your buildable area is dictated by how close the ADU can get to your property lines:
- Standard Rule: New detached ADUs generally require a 4-foot setback from the side and rear property lines.
- San Diego Bonus: In the City of San Diego, you can often build a single-story ADU right up to the property line (0-foot setbacks), provided it remains under 16 feet in height and sits outside strict fire hazard zones.
- Conversions: Converting an existing structure (like a detached garage) bypasses new setback rules entirely. Your ADU can occupy the exact footprint the garage always has.
Maximum ADU Sizes
If you have a larger lot and want to build past the 800-square-foot baseline, your limitations shift depending on the ADU style:
- Detached ADU: You can build up to 1,200 square feet in San Diego, assuming you have the yard space.
- Attached ADU: Limited to 1,200 square feet or 50% of the main home’s size (whichever is less).
- Junior ADU (JADU): Limited to 500 square feet and must be built entirely within the existing footprint of the main home.
