Menifee, CA Accessory Structures: ADU Impact Fees (2026)

03 imposes a Local Development Mitigation Fee (LDMF) on new development to fund the Western Riverside County Multiple Species Habitat Conservation Plan (MSHCP). 050(A), no building permit may issue until the applicable LDMF is paid, and the amount is set using the MSHCP Mitigation Fee Implementation Manual. 090 lists exemptions from the chapter, and subsection (C) states that accessory dwelling units are exempt "but only to the extent such fee is exempted under state law," with subsection (D) applying the identical limited exemption to junior accessory dwelling units.

In practice this ties Menifee's habitat fee treatment of ADUs directly to state ADU law rather than granting a blanket local waiver: an ADU only escapes the LDMF where California law itself bars the charge, otherwise the fee is calculated and collected like any other development. 080(B), and the city may add a separate administrative surcharge to cover its own collection costs without reducing the RCA's remittance. 070 allows a refund of the LDMF, less administrative costs, if a building permit expires or is voluntarily surrendered before construction begins, but the request must be filed within three years of the original payment, and reapplying for a permit later requires paying the fee at the rate then in effect. 100, consistent with the MSHCP Mitigation Fee Implementation Manual. The chapter was adopted by Ord. 2022-364, passed November 16, 2022.
