ADUs are allowed in all single-family and multifamily residential zones. Maximum attached/detached ADU floor area is 1,500 sq ft; JADUs are capped at 500 sq ft and must be carved from the existing single-family residence.

One off-street parking space is required unless waived (transit-proximity, historic district, conversion, etc.).

Some RestrictionsADU Permits
ADUs and JADUs are approved ministerially through building plan check — no discretionary review or hearing — consistent with Cal. Gov. Code §65852.2(b). The City must approve or deny a complete application within 60 days of receipt (§9.295.020.C.2). If denied, the City must return a written list of deficiencies (§9.295.020.C.3). Menifee also offers City-approved Permit Ready ADU Plans that skip building plan check, requiring only a site plan for Planning/Building/Engineering/Fire review (§9.295.020.C.1).

Few RestrictionsADU Impact Fees
Menifee Development Code §9.295.020.C.6 waives development impact fees for any ADU under 750 sq ft. ADUs of 750 sq ft or larger are charged impact fees proportional to the square footage of the primary dwelling, tracking Cal. Gov. Code §65852.2(f)(3). §9.295.020.D.3 separately bars treating an ADU as a 'new residential use' for water/sewer connection fees or capacity charges. JADUs are categorically excluded from connection fees under §9.295.020.E.4.m.
ADU impact fees — waived under 750 sq ft (§9.295.020.C.6)
Few RestrictionsADU Owner Occupancy
Menifee follows the state-mandated split: ADUs do NOT require owner-occupancy of the primary dwelling, but Junior ADUs (JADUs) DO. §9.295.020.E.4.j requires the owner of a single-family property with a JADU to record a covenant stating that either the remaining portion of the primary dwelling or the JADU itself will be occupied by the property owner. Owner-occupancy is waived if the owner is a governmental agency, land trust, or housing organization. ADUs permitted between January 1, 2020 and January 1, 2025 are statutorily owner-occupancy-free under Cal. Gov. Code §65852.2(a)(7).
Owner-occupancy — required for JADUs, not for ADUs (§9.295.020.E.4.j)
Some RestrictionsADU Rental Restrictions
Menifee Development Code §9.295.020.E.1.d and §9.295.020.E.2.d expressly prohibit renting an ADU for less than a 30-day period. §9.295.020.E.4.c applies the same 30-day minimum to Junior ADUs. This effectively bars short-term/vacation rental of ADUs (no Airbnb-style stays). Long-term rentals (30+ days) are explicitly permitted under §9.295.020.E.1.c and §9.295.020.E.2.c, consistent with Cal. Gov. Code §65852.2(a)(6).

Some RestrictionsShed Rules
Menifee Development Code Chapter 9.165 (Accessory Structures & Amenities) regulates sheds and detached accessory buildings. California Building Code (Title 24 Part 2 §105.2) exempts one-story detached sheds 120 sq ft or less from building permits, but Menifee zoning setbacks and HOA rules still apply. Larger sheds require a building permit through the Community Development Department (951-723-3741).
