Home Addition Contractor in Brentwood
A home addition in Brentwood can mean a second story on a flat lot south of Sunset or a careful rear wing on a hillside lot toward Mandeville Canyon. The two are very different. Flat lots have more room to build. Hillside lots fall under the Baseline Hillside Ordinance, with caps on size and height and more grading review. We check which rules apply to your parcel before design. Then we run engineering, LADBS plan check, framing, and a finish match so the addition looks original.

Home Additions in Brentwood
Second story or rear wing
A second story keeps the yard but means a bigger structural job and usually time out of the house. A rear wing keeps you home but uses yard space. We price both for your lot so you can compare.
How it works
Premier Hi-End Builders is a home addition contractor across Greater Los Angeles, building room additions, second story additions, and suite additions. We handle feasibility, drawings, structural engineering, and plan check, then match stucco, roofing, and trim to the existing house.
We look at your lot, setbacks, and what the city will allow before anything gets drawn. Hillside conditions and HOA rules get checked here.
Plans go to an architect and a structural engineer. You see layout and elevations before they head to plan check.
We submit the plans to your city and handle any corrections. Plan check takes longer in some cities than others, and we give you a realistic timeline for yours.
We pour the footings, build the slab or raised floor, frame the walls, and tie in the roof. Inspections are scheduled as each stage is finished.
We match the stucco, siding, roofing, windows, and interior finishes to the existing house, so you can't tell where the old part ends.

FAQ
Common questions about home additions in Brentwood
On hillside lots, especially toward Mandeville Canyon and the Santa Monica Mountains, yes. It limits floor area and height. Flat lots south of Sunset are usually outside it.
For most rear additions, yes. Second stories often need a move-out during the roof and framing stage. We tell you when that stretch is coming.
Lot setbacks, hillside or HOA rules, and how the new room should connect to the house. We check feasibility before drawings so you are not paying for a plan the city will reject. The free LA Remodel Decision Sheet lists what to settle before you call an architect.
Living space additions, second story additions, extra bathrooms, home offices, and guest or primary suites. Many owners pair an addition with a kitchen remodel so one crew handles both.
