ADU Construction · Granite Hills, CA

ADU Construction in Granite Hills, CA.

ADU Construction for Granite Hills homes by The Rock Remodels, a licensed San Diego County contractor. Building an ADU takes two things most contractors cannot offer under one roof: a permitted design that clears San Diego County plan check, and a licensed GC who can actually build it. The Rock Remodels handles construction.

Granite Hills: Granite Hills and the surrounding canyons, including Harbison Canyon and Dehesa, mix larger custom properties with older ranch homes on generous lots. Many homes here were built in the 1960s through 1980s and have never had a significant interior update, making them strong candidates for kitchen and bath remodels, additions, or whole-home renovations.

Why is adu construction different in East County San Diego?

ADU construction in El Cajon, Santee, Lakeside, and Alpine requires sorting out jurisdiction early because county-governed parcels and city-incorporated properties do not follow the same rules, fees, or inspection timelines, and that distinction is not always obvious from an address. Older electrical panels are a consistent factor in East County, and an ADU build almost always includes a panel evaluation and often an upgrade as part of the project scope. David manages that coordination so the build moves forward rather than stalling on the jurisdictional complexity that delays less experienced contractors.
