South Bay New Construction.

Ground-up homes across LA — Hollywood Hills, Brentwood, Pacific Palisades, the Westside. Architect coordination, LADBS permit, build with regular crew.

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.

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.
