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 detached adu different in East County San Diego?

El Cajon, Santee, and Alpine properties often straddle city and county jurisdiction lines, which changes the permit path significantly, and that's where a lot of owners get stuck. Older electrical panels are common and detached builds sometimes require a service upgrade before the ADU can even be energized. We know how to navigate those layers so the project doesn't stall six months in.
