Home Additions FAQ
How much does a home addition cost in San Diego?
Most home additions in San Diego range from $250–$500+ per square foot depending on size, architectural complexity, utilities, and finish level. Smaller bump-outs cost less, full second-story additions cost more. We provide detailed, written estimates after an on-site visit.
How long does a home addition typically take?
A standard home addition takes 3–6 months from design to completion for a simple project. Larger or more complex projects, such as second stories or structural changes, may take 6–12 months. We handle all engineering, permitting, inspections, and scheduling.
Do home additions require permits in San Diego County?
Yes. Almost all home additions require plans, engineering, and a building permit. As licensed home addition contractors, we handle the entire process for you, including navigating city-specific building requirements.
Will a home addition increase my property value?
Yes. Properly designed and permitted home additions often provide one of the highest returns on investment. Added square footage, especially bedrooms and bathrooms, typically increases resale value significantly.
Can you match my home’s existing style and materials?
Absolutely. We create seamless additions that look like they were always part of the original home; matching rooflines, stucco texture, windows, interior finishes, and more.
What types of home additions do you build?
We design and build room additions, second-story additions, lofts, attached (and detached) ADUs, bump-outs, master suites, garage conversions, expanded living rooms, and multi-room expansions- each customized to your specific wants, needs, and budget.
