Solana Beach is a small, premium coastal city where almost every ADU project triggers coastal review and detached units are capped smaller than in inland cities. The upside is real — strong rents and high property values — but the rules reward efficient design and clean permitting. That's exactly the work a coastal-experienced design-build team takes off your plate.

Why build an ADU in Solana Beach?

Built for small coastal lots

Solana Beach caps detached ADUs smaller, so we design efficient layouts that make the most of every square foot.

Citywide coastal review handled

Essentially every project needs a CDP — we design and document to clear it.

One accountable team

Architecture, permitting and construction under one roof — one contract, one point of contact.
