Frequently Asked Questions
Answers for Los Angeles Homeowners
How much does a room addition cost in Los Angeles?
A single-room addition typically costs $250 to $450 per square foot, so a 300-square-foot room often lands in the $80,000 to $150,000 range. Cost depends on the room purpose; a bedroom is simpler than a new bath or kitchen.
How long does a room addition take?
Most room additions take 3 to 6 months from permit to finish, depending on size and whether plumbing or a new bathroom is involved. We integrate the new foundation and roofline into your existing home seamlessly.
Do room additions need permits?
Yes. Adding square footage requires LADBS permits and plan check, including zoning review for setbacks. We handle the paperwork, engineering, and inspections from start to finish.
Will the new room match my existing house?
That is our priority. We match rooflines, exterior finishes, flooring, and trim so the addition looks original to the home, not bolted on. Seamless integration protects both the look and the resale value.
