Orange County Multifamily Remodeling.

Multifamily remodels across LA — common areas, in-place unit upgrades, full vacant-unit turns. We coordinate around occupied tenants and work with the LADBS multifamily permit track.

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

$80 – $300 / sqft per unit

Cosmetic unit refresh bottom; full down-to-studs top.

Orange County permit clock

6–10 weeks ministerial

3–9 months per building depending on scope.

Scope — start to keys.

  • Scope walk + tenant coordination plan
  • Plans + permits
  • Common-area + unit work
  • MEP upgrades
  • Final inspection + handover

What changes about the permit here.

  1. Irvine, Anaheim, Santa Ana: online ADU portals, typically 6–8 weeks ministerial.
  2. Coastal Zone in Laguna, Newport, parts of Huntington — CDP may be required.
  3. Master-planned-community HOAs review independently of city building & safety.
  4. 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.

Can you do an LA multifamily remodel with tenants in place?
Yes — common area + unit-by-unit turn. Tenant coordination plan and Habitability Plan handle the schedule.
Multifamily remodel cost per unit in LA?
$30K–$80K for cosmetic refresh; $120K–$250K full down-to-studs per unit.
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.
