Local context

Building an ADU in Kearny Mesa

Homeowners near Convoy Street, the Montgomery Field corridor, and the quieter residential streets tucked behind the 92111 zip code are sitting on real options when it comes to ADUs. Kearny Mesa is not typically thought of as a residential neighborhood, but the families who do own property here know what they have: proximity to everything, reasonable lot sizes compared to the coast, and rental demand that does not let up. ADUz handles the design, permits, and full build for homeowners in this area, working through City of San Diego jurisdiction and navigating the site realities that come with older multi-family adjacent lots. Whether the goal is a granny flat for a parent, a rental unit to offset a mortgage, or long-term housing for an adult child, the feasibility often surprises people once someone actually looks at the lot.

Because Kearny Mesa falls entirely within City of San Diego jurisdiction, ADU projects here go through the city's permitting process rather than the county, which means different timelines, setback rules, and review queues than neighboring unincorporated areas. The residential stock in 92111 and 92123 leans older and denser, with a mix of attached homes, small multi-unit parcels, and the occasional single-family lot along quieter side streets off Convoy and Balboa Avenue. Detached ADUs on smaller lots are common here, and garage conversions make sense on properties where a separate structure already exists. Height, setback, and lot coverage limits vary by parcel type, so a site visit and feasibility check early in the process matters more here than in a straightforward suburban neighborhood. Alma and the team at ADUz know this part of the city and will tell you honestly what will and will not work before anything goes to the city.

Kearny Mesa FAQs

What do Kearny Mesa homeowners ask?

What does an ADU cost to build in Kearny Mesa?

A detached ADU in Kearny Mesa typically runs somewhere in the $180,000 to $350,000 range depending on size, finish level, and site conditions. Garage conversions tend to land on the lower end since the structure is already there. ADUz gives you a realistic number after seeing the lot, not before.

How long does the permit and build process take in Kearny Mesa?

City of San Diego permit review for ADUs currently runs several months depending on plan complexity and current queue volume. Once permits are approved, construction on a detached unit typically takes four to seven months. ADUz manages the full timeline so you are not chasing the city on your own.

What type of ADU fits a Kearny Mesa property?

Most residential lots in this area are smaller and sit in a denser context, which makes compact detached units and garage conversions the most practical options. A junior ADU inside the existing home footprint is also worth exploring on the right property. Alma reviews your lot and tells you which type makes the most sense given your setbacks, coverage limits, and goals.
