Cost to replace LA home windows?

$650–$1,200 vinyl; $1,400–$2,200 fiberglass or aluminum-clad. Per opening installed.

Retrofit vs full-frame?

Retrofit saves $200–$400/opening but requires good existing frames.

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.

LA window + door — full-frame or retrofit, Milgard, Andersen, Marvin. Title 24 U-factor and SHGC compliance every job.

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.
