Full Breakdown
Colusa County Code Chapter 44 (Zoning Code) does not define 'carport' separately but defines a 'private garage' as 'a fully enclosed accessory building, either attached or detached, or a portion of a building designed and/or used primarily for the shelter or storage of vehicles, trailers, recreational vehicles, and boats by the occupants of the dwelling' (Sec. 10). A carport is a roofed vehicle-shelter accessory structure and is regulated under the same accessory-structure development standards as other accessory buildings. ' The zone's maximum height and lot-coverage limits also apply.
A building permit from the Colusa County Building Division is required for a permanent carport. Because the front-yard setback is the most restrictive (20 feet), a vehicle-shelter that fronts the street must be set well back from the front property line. Standards differ in the agricultural and other classifications, so verify the rules for your zone with Colusa County Planning & Building.
Violations & Fines
Erecting a carport within a required setback, closer than 5 feet to another building, above the zone's height limit, or without a required building permit is a violation of the Colusa County Zoning Code and the adopted building codes. Code enforcement may require correction or removal and may abate the structure as a public nuisance.
