Full Breakdown
Moorpark Municipal Code § 17.24.020(E)(5) permits converting a garage into habitable space only when the property owner replaces the lost covered parking with equivalent covered parking meeting Chapter 17.32's parking standards. The requirement applies in the O-S, A-E, R-A, R-L, R-E, R-1, R-2, and R-3 zones. The city waives this replacement requirement when the conversion is done under Section 17.28.020(G) to create an accessory dwelling unit, reflecting state ADU parking preemption. Homeowners need a Community Development building permit, and plans must show where the replacement parking will go before work is approved.
Violations & Fines
Converting a garage without replacing covered parking, or without a permit, is a zoning violation; Community Development can require restoring parking or the garage space.
