Coastal ADU Builder

La Jolla ADUs, built by the owner.

In La Jolla, where lots are premium and the coastal overlay is real, Troia builds ADUs that respect the neighborhood and the view, led on site by the owner who is based right here in the Village.

Why build here

Why build an ADU in La Jolla?

La Jolla ADUs are as much about discretion as square footage. Tight lots, established streetscapes, and discerning neighbors mean the detailing has to be right. We design ADUs that read as part of the property, not an afterthought bolted onto the back.

Proximity to UCSD and the coast makes La Jolla one of the strongest rental markets in the county. A guest house, studio, or detached ADU here is a serious asset, and we build it to a standard that holds up to both the salt air and the resale appraiser.

Permitting

Approvals in La Jolla.

La Jolla is part of the City of San Diego, so ADUs go through City Development Services, but much of La Jolla also sits in the Coastal Zone. That can add a coastal review on top of the standard ADU process. We map your parcel against the overlay early so there are no surprises mid-build.

We handle drawings, submittal, plan-check responses, and inspections, so you get a finished ADU instead of a paperwork project.

La Jolla ADU questions

Good to know.

01Do I need a coastal permit for an ADU in La Jolla?
Many La Jolla properties fall inside the Coastal Zone, which can trigger a coastal review in addition to the standard ADU permit. We check your parcel against the overlay before design so the path is clear.
02How big can a La Jolla ADU be?
State law generally allows detached ADUs up to roughly 1,200 square feet, though lot coverage and height limits in coastal La Jolla can shape the final envelope. We design to maximize what your specific lot allows.
03Can you match my La Jolla home’s architecture?
Yes. We routinely match stucco, rooflines, and trim so the ADU reads as original to the property, which also smooths neighborhood and design review.
