Summary
Carson lets homeowners convert a required garage, carport or parking space into living area only if they replace the same type and number of parking spaces elsewhere on the lot with adequate access provided.
Any garage, carport or parking space required for a dwelling may be converted to additional living area or any other permitted nonparking use; provided, that at least the same type of parking shelter or area and number of spaces as lawfully exist at the time of such conversion are provided elsewhere on the lot and adequate access is provided thereto. Nothing in this Section shall be construed or applied so as to require parking shelters or areas or number of spaces in excess of the requirements of this Division. This Section shall not apply when a garage, carport or parking space is converted to an accessory dwelling unit or junior accessory dwelling unit, in which case CMC § 9122.1(E)(9)(e) shall govern. (Ord. 22-2211 § 16)
Full Breakdown
Under Carson's off-street parking standards, a garage, carport or parking space required for a dwelling may be converted to additional living area or any other non-parking use, but only if the same type of parking shelter or area and the same number of spaces that lawfully existed at the time of conversion are provided elsewhere on the lot, with adequate access. The Section does not require more parking shelters or spaces than the underlying parking division otherwise demands. It carves out one exception: converting a garage, carport or parking space into an accessory dwelling unit or junior accessory dwelling unit is instead governed by Carson's ADU ordinance, CMC § 9122.1(E)(9)(e), which implements the state-law ADU floor set by Government Code §§ 66310-66342.
Violations & Fines
Converting a garage to living space without providing the same type and number of replacement parking spaces elsewhere on the lot is a Zoning Ordinance violation; the Community Development Department can deny related permits or require the parking to be restored.
