How we work

One team, beginning to end.

01
Design + structural

Layout, elevations, and structural engineering for the tie-in. We confirm what the existing foundation and roof can carry before anything is priced.

02
Permit + prep

Permit pulled with the city. Site protection, temporary weatherproofing, and selective demo where the addition meets the house.

03
Build

Foundation, framing, MEP, roofline, and finishes. Typically 4–7 months on site, depending on size and how much of the existing house is opened up.

Frequently asked

Common questions.

How long does a home addition take?+

Design and structural engineering: 6–10 weeks. Permit: 6–12 weeks depending on the jurisdiction. On-site construction: 4–7 months. Total from kickoff to final inspection: roughly 8–12 months.

What does an addition cost in San Diego?+

Most additions we take on land between $180,000 and $450,000. Size, single-story versus a second story, foundation conditions, and how much of the existing house is reworked at the seam all move the number. We give a real figure after a site walk.

Can you add a second story?+

Yes. Second-story additions need a structural review of the existing foundation and walls — sometimes they carry the load as-is, sometimes they need reinforcement. We confirm that in the design phase before you commit to the scope.

Can we live at home during an addition?+

Usually yes. An addition is built largely outside the existing footprint, so we seal the connection point and keep the rest of the house livable. We open the wall between old and new late in the schedule.

Do you handle permits and HOA approval?+

Yes. We pull the building permit and prepare the structural and Title 24 documents. If your property has an HOA, we prepare the submittal package for their architectural review.
