Who This Is For

More space, built right

When your home has outgrown its footprint but the location is right, an addition is often the smarter move over buying and moving. Getting it right means structural engineering, permitting, and construction that all work together, and a finished result that looks like it was always part of the house.

Statera manages the structural, design, and construction sides of your addition as one coordinated project.

Common Questions

Additions & expansions FAQ

How much does a home addition cost in San Diego?

Home additions in San Diego typically range from $100,000 to $300,000 depending on square footage, whether it's a single-story or second-story addition, and finish level. Second-story additions run toward the higher end due to structural requirements.

Do I need a structural engineer for an addition?

Yes, for most additions. We coordinate with a licensed structural engineer as a standard part of the design process to ensure the addition is engineered correctly and passes plan check the first time.

Will my addition match the rest of my house?

Yes. Our design team works from your home's existing architecture, rooflines, and materials so the addition reads as original construction, not an obvious add-on.
