Frequently Asked Questions
Answers for Los Angeles Homeowners
How much does a home addition cost in Los Angeles?
Home additions typically run $250 to $500+ per square foot in Los Angeles, higher than a basic remodel because you are adding new foundation, framing, roofing, and systems. The exact figure depends on the room type and site conditions.
How long does a home addition take?
Most additions take 4 to 8 months from permit approval to completion, depending on size and whether it is a ground-floor or second-story addition. Foundation and framing inspections are built into the schedule.
Do I need a permit for a home addition?
Always. Any addition that expands your footprint or adds square footage requires LADBS permits, plan check, and often zoning review for setbacks and height. We manage the full approval process for you.
What is the difference between a home addition and an ADU?
A home addition expands your existing house, while an
ADU is a separate, independent dwelling with its own entrance and kitchen. Additions suit growing families; ADUs suit rental income or multigenerational living.
Can you add a second story to my house?
Yes. Second-story additions are a great way to gain space on a tight LA lot. They require a structural evaluation of the existing foundation and seismic engineering, both of which we handle in-house.
