Key Benefits

With our Pre-Approved ADU plans (designed to fit small lots as narrow as 25' wide), much of the design and permitting work is already completed, so there is less chance for delay or unexpected costs down the road. And because this plan has already received prior approval from the City of San Diego, you can be confident that your ADU will meet all city requirements, as well as in surrounding localities.

Way More Than Just a

The Harrison ADU

The Harrison ADU is a perfect case study of "house hacking" as the front rental unit offsets the mortgage cost making this a positive cashflow property. Other unique features include a clean minimalist interior, energy efficient design and a high degree of privacy despite being on a tight urban lot in the Logan Heights neighborhood of San Diego.

The Prince House ADU

The Prince House ADU is our own self-funded ADU project by the owners of Ten Seventy Architecture. From the very beginning, it was designed + built to be a showcase of how high-end minimalist ADU design can be applied to tight lot conditions and easily replicated throughout the City of San Diego.

The Everett ADUs

The Everett ADUs is an awesome showcase of how multiple ADUs can be fit on one lot with smart planning. By adding two ADUs behind the main house, our client is able to generate rental income from three units. This shows how ADUs add much-needed housing in San Diego while also generating passive income for the owner.
