Why Build or Buy an ADU in Perris?

Larger suburban lots increase ADU placement flexibility. Many Perris communities provide roomy backyards compared with coastal counties—ideal for detached ADUs.
State law protects reduced setbacks and ADU approvals. California’s ADU statutes require Perris to allow certain 4-foot rear/side setbacks and ministerial approval when plans meet state standards.
Strong demand for multi-gen and long-term rentals. Perris’ growing population and commuter access create consistent demand for ADU-style units.
Permitted ADUs strengthen long-term resale value. A legal ADU often improves appraisal outcomes—especially in newer communities where space is at a premium.
