Building in Goleta
Adding space in the Good Land.

Goleta's many single-story homes from the 1950s through the 1970s are natural candidates for garage conversions, backyard ADUs and ground-floor additions.
Older garages here often have framing that can be kept, as in one Carpinteria conversion just down the coast, where the existing roof and beams stayed and spray foam brought the rafters to R-38. On additions, matching original rooflines and siding keeps the house looking cohesive.
Goleta has set up a preapproved ADU program under state law, with designs going through the city's Design Review Board before they are offered to homeowners. It is worth comparing what is available with custom plans for your lot.
What to know in Goleta

- Designers submitting plans to the program go before the city's Design Review Board and pay a planning review fee before building plan review.
- Garage conversions and junior ADUs are permitted under state ADU law and do not depend on the preapproved program.
