Home Addition Plans
Permit-ready architectural plans for room additions, second-story additions, primary suite additions, and bump-outs across Greater Sacramento.
From Concept to Permit-Ready Plans
Adding square footage to your home is one of the most complex residential projects you can undertake. Before a single line is drawn, we review your setbacks, lot coverage limits, and the structural capacity of your existing home — so your plans are buildable from day one. Structural design is completed and stamped by licensed California engineers, coordinated in-house by our team.
Setback & Lot Coverage Review
We check your parcel's zoning setbacks and maximum lot coverage before design begins — no surprises at plan check.
Structural Design Coordination
Structural design is completed and stamped by licensed California engineers — coordinated in-house so you have one point of contact throughout.
Title 24 Energy Coordination
We coordinate the required Title 24 energy compliance report with a certified energy consultant.
One Point of Contact
We manage the entire process — plans, consultants, permit submittal, and corrections — so you don't have to.
