Full Breakdown
020 sets the placement rules for accessory buildings -- including detached garages and carports -- in Chula Vista's R zones (all except R-3-T). An accessory building that is not attached to the main house must stand at least six feet from any dwelling on the same lot or an adjacent lot. 1 lets a detached garage or carport, or a covered patio enclosed on no more than two sides, disregard any rear or side yard requirements only if it sits in the rear 30 percent of the lot, or behind the front 70 feet of the lot -- outside that zone, normal yard setbacks apply in full.
2 requires any accessory building or covered patio located within 70 feet of the front property line to match the same side-yard setback required for the main house, whether or not it's physically attached. 3 caps how much of a required rear yard a carport, detached garage, or other one-story accessory building may cover at 30 percent, though no accessory building sitting in a rear yard is required to be smaller than 400 square feet. 4 requires a covered patio or detached accessory building in the qualifying rear zone to sit either directly on the property line or set back at least three feet from it -- no closer.
Every accessory building, including carports, counts toward the lot's overall lot-coverage calculation under subsection C, and an attached carport must meet every Title 19 standard applicable to the main building.
Violations & Fines
Building or enlarging a carport, garage, or covered patio without meeting these placement and coverage standards is a Municipal Code violation enforceable under CVMC 1.20.010 -- charged as an infraction (up to $100 for a first offense) or a misdemeanor (up to $1,000 and/or six months in jail), with each day the structure remains noncompliant treated as a separate violation. The Development Services Department can also require removal or relocation through the building permit process.
