Additions that read as the original house.

Room additions in OC typically run $400–$700+ per sqft for finishes and structure. A 400-sqft single-room addition lands around $160K–$280K+; a 800-sqft second-story addition runs $320K–$560K+. Avorino quotes a fixed-price design-build contract so the budget is locked at week one.

From permit to certificate of occupancy: 4–6+ months for a single-room addition, 6–10+ months for a second-story or primary-suite expansion. Permitting itself adds 4–8+ weeks. Avorino weather-protects the existing structure during the build so you can stay in the home.

Yes. Any addition that changes the building footprint, roofline, or adds livable square footage requires a building permit and structural review. Avorino pulls every required permit under General-B License #1107538 and carries plan-check + final inspection.

Yes. That's the core craft of a good addition. We source matching roof tile, exterior plaster, window profiles, and interior trim so the addition reads as original to the house. For older homes where the original material is discontinued, we propose the closest current equivalent before construction starts.
