Westside 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.
Westside permits move quickly when the parcel is clearly inside the city of LA or Santa Monica grid — both jurisdictions run ministerial ADU review under state law. The variables are Coastal Zone status (anything west of Lincoln Blvd in Venice / Marina Peninsula), and whether a soft-story or seismic ordinance applies to the existing structure.
Westside cost band — 2026
$28K – $85K
Walk-in shower glass, slab counters, and moving plumbing fixtures push toward the top of the band.
Westside permit clock
8–12 weeks ministerial
Plan on 2–3 weeks for design + permit, then 4–6 weeks on-site.
Scope — start to keys.
- Demo, slab inspection, sub-floor repair if needed
- Copper or PEX repipe, drain re-route, shut-off valves
- Schluter or hot-mopped pan, waterproofing, niche framing
- Tile, stone slab, glass enclosure, vanity, mirror, lighting
- Vent fan, dedicated circuits, GFCI, Title 24 compliance
What changes about the permit here.
- City of LA parcels: LADBS ePlanLA portal, ministerial ADU review under LAMC §12.22-A,33.
- Santa Monica parcels: SMMC §9.31.300 — locally streamlined, similar 60-day clock as state law.
- Coastal Zone (Venice west of Lincoln, Marina Peninsula): Coastal Development Permit may be required.
- Mello Act applies to demolition or replacement of existing residential units in the Coastal Zone.
What moves the Westside number.
- Westside labor and dump fees price 8–12% above LA County median.
- Coastal Zone parcels often add $15–40k in CDP consultant + biology survey costs.
- Santa Monica seismic retrofit pairing on a duplex can add $35–80k tied to the ADU permit cycle.
- Tight street parking (Venice, Mar Vista) drives crane / pump days higher than Valley jobs.
In short.
- 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 long is a bath remodel unusable?
- Plan on 4–6 weeks of the bath being completely offline. We sequence so most of the demo and rough is in the first two weeks, then tile and finish.
- Do I need a Coastal Development Permit for a Westside ADU?
- Only if the parcel is inside the Coastal Zone — generally west of Lincoln Blvd in Venice and the Marina Peninsula. Inland Westside parcels (most of Santa Monica, Brentwood, Mar Vista east of Lincoln) do not.
- Can I build an ADU in Santa Monica's R1?
- Yes. SMMC §9.31.300 mirrors state ADU law on R1, R2, and multifamily lots, with ministerial 60-day review once the submittal is complete.
