How much does a whole-home remodel cost in Los Angeles?

Whole-home down-to-studs remodels in LA typically run $450–$850/sqft installed. Foundation retrofit, full repipe/rewire, and finish level drive the band.

Do I need to move out during a whole-home remodel?

Usually yes — for a true down-to-studs project, the house is not livable for 6–10 months. Some lighter whole-home projects can be phased.

How big can my detached ADU be in the Valley?

State law guarantees up to 1,200 sqft on a single-family lot, regardless of local FAR limits. Most Valley lots can fit a 1,000–1,200 sqft 2BR detached unit.

Do I need a Mulholland Specific Plan review?

Only if your parcel is inside the Mulholland Scenic Parkway Specific Plan boundary — primarily the south-facing ridgeline of Sherman Oaks, Encino, and Tarzana. We check the parcel on the first walk.

San Fernando Valley Whole-Home Remodeling.

A whole-home remodel in LA is usually a down-to-studs project on a 1920s–1960s house. The shell stays; everything inside gets rebuilt — foundation bolting, soft-story retrofit, repipe, rewire, HVAC, insulation, drywall, finishes. We run the architecture, the LADBS permit, and the construction under one contract.

The Valley is the most predictable corner of LA city for an ADU permit. Standard R1 lots, flat topography, and LADBS's online portal mean state ADU law applies cleanly with no neighbor notice and no discretionary review. The two variables are the Mulholland Scenic Parkway Specific Plan (south-side hillside parcels) and Very High Fire Hazard Severity Zones.
