El Cajon: El Cajon's inland location means summer temperatures regularly climb past 100 degrees, and that heat, combined with a 50-year-old housing stock of small-lot ranch homes, creates real pressure on families who need more space but can't afford to move. ADUs give homeowners in Bostonia and Fletcher Hills a way to add that space without leaving the neighborhood they've built their lives in.

Why is adu construction different in East County San Diego?

In El Cajon, Santee, and the unincorporated areas near Alpine, jurisdiction matters as much as construction quality because county rules and city rules don't always line up, and a project that's fine under one may need changes under the other. Older electrical panels are common here, and an ADU often triggers a panel upgrade that has to be factored into the budget and timeline from the start. ADUz handles the permitting side so Rock Remodel can focus on building it right.
