Menifee FAQ

Will I owe impact fees on a Menifee ADU?

Only if the ADU is 750 sq ft or larger. §9.295.020.C.6 waives impact fees below that threshold and requires proportional charges (relative to primary-dwelling size) above it.

What about water and sewer connection fees?

§9.295.020.D.3 bars the City from treating an ADU as a new residential use for connection or capacity charges. EMWD may still charge for a new physical connection under §9.295.020.E.2.q.

Are JADUs charged connection fees?

No. §9.295.020.E.4.m treats a JADU as part of the existing single-family dwelling for water, sewer, and power connection-fee purposes.
