South Bay 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.
South Bay permits hinge on which beach city you're in. Manhattan, Hermosa, and Redondo each enforce a local ADU ordinance that's stricter than LA city's, capping detached unit size and adding parking rules in some sub-areas. Coastal Zone status and Palos Verdes geotech are the biggest schedule variables.
South Bay cost band — 2026
$450 – $850 / sqft installed
Structural retrofit needed, foundation work, finish level, and whether you keep or replace windows drive the band.
South Bay permit clock
8–14 weeks ministerial
Plan on 5–8 months for design + LADBS permit, then 8–14 months on-site for a 2,000–3,500 sqft house.
Scope — start to keys.
- Soft-story / seismic retrofit, foundation bolting, cripple bracing
- Full repipe (copper or PEX), full rewire, 200A panel
- HVAC redesign, ducting, mini-splits where ducted is impossible
- Insulation to current Title 24, exterior weatherization
- Kitchen, all baths, floors, millwork, paint, landscape repair
What changes about the permit here.
- Manhattan Beach: ADU ordinance MBMC §10.24 — local design review for street-facing facades.
- Hermosa Beach: tight side-yard setbacks on legacy walk-street lots.
- Coastal Zone parcels (most of MB / HB) require a Coastal Development Permit.
- Palos Verdes Peninsula: Portuguese Bend Landslide Complex overlays — geotech is mandatory, not optional.
What moves the South Bay number.
- Highest detached cost in our service area — small lots, walk-street access, dump fees.
- Coastal Development Permit consultant + biology costs commonly $20–60k on MB / HB lots.
- Palos Verdes geotech (landslide complex) can add $35–100k in foundation engineering.
- Local design review in Manhattan Beach often pushes architectural fees 25–40% higher.
In short.
- 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.
- Should I do a seismic retrofit at the same time?
- Yes — when the walls are open, the marginal cost of foundation bolting and cripple-wall bracing is small. Doing it later costs 3–5× more.
- Can I build a full-size 1,200 sqft ADU in Manhattan Beach?
- MBMC §10.24 caps detached ADUs below state max in some lot sizes. We size the unit against the local ordinance during the feasibility walk.
- Do I need a Coastal Development Permit in Hermosa?
- Most of Hermosa Beach sits inside the Coastal Zone. A CDP is typically required unless the project qualifies for a categorical exclusion.
