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.
