What applies to your lot
Building an ADU in Rialto
Who approves your ADU
City of Rialto, in San Bernardino County. State law applies everywhere: a decision within 60 days of a complete application, no public hearing, and at least 800 sq ft with 4 ft side and rear setbacks.
On request
Rialto is about 47 miles from our base in Paramount. We accept projects there case by case, depending on the schedule of our crews.
Pre-selected city plans
Rialto offers a set of pre-approved ADU plans in several sizes, a good start for a detached unit.

Inland summers are hot. We size insulation, windows and the mini-split for comfort, and a new detached ADU includes its own solar panels.
