How much does a bathroom remodel cost in Los Angeles?

Most LA bathroom remodels land between $28K and $85K. Walk-in shower glass, slab counters, and moving plumbing fixtures push toward the top.

Do I need a permit to remodel a bathroom in LA?

Yes — any work that touches plumbing, electrical, or structural triggers an LADBS permit. A like-for-like fixture swap does not.

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 Bathroom Remodeling.

LA bathrooms are usually small, almost always over an older slab or first-story floor, and almost always hiding a plumbing surprise. We do the demo carefully, repipe what needs repiping, get the waterproofing right, and land tile, stone, lighting, and fixtures that read luxury without leaking in three years.

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.
