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.

Can my Irvine HOA block an ADU?

No. State law preempts HOA prohibition of ADUs. The HOA can review materials and elevations, but cannot deny the permit outright.

Do I need a CDP for a Newport Beach ADU?

Most of Newport's Balboa Peninsula and oceanfront sit in the Coastal Zone, requiring a CDP. Inland Newport parcels typically do not.

Orange County 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.

Orange County permits are quick when the parcel is in a streamlined city (Irvine, Anaheim, Santa Ana) and slower when the city is small and beachfront (Laguna, Newport's Balboa Peninsula). The most common schedule risk is the master-planned-community HOA — the building permit is fast, but the architectural review committee runs on its own monthly schedule.

Orange County cost band — 2026

$450 – $850 / sqft installed

Structural retrofit needed, foundation work, finish level, and whether you keep or replace windows drive the band.

What changes about the permit here.

Irvine, Anaheim, Santa Ana: online ADU portals, typically 6–8 weeks ministerial.
Coastal Zone in Laguna, Newport, parts of Huntington — CDP may be required.
Master-planned-community HOAs review independently of city building & safety.
Newport-Inglewood Fault Zone parcels need an Alquist-Priolo geotech investigation.

What moves the Orange County number.

Master-planned HOA design review pushes architectural / cladding budgets 15–25% higher.
Coastal Zone CDP in Laguna / Newport adds $20–60k in soft costs and timeline.
Alquist-Priolo geotech (Newport-Inglewood) commonly $12–30k.
Irvine / Anaheim labor cost runs at LA County median.

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.
