Summary
The ULMO treats a carport attached to the principal home as an accessory use when it is at least 75 percent open or unenclosed. It must meet the Table 3 setbacks that apply to accessory uses. Enclosing a carport can reclassify it and change setback requirements.
Included in this definition are private garages, storage sheds, workshops, domestic animal shelters, pool houses, etc., when detached from the principal buildings, and carports attached to the principal building when at least 75 percent open or unenclosed.

Full Breakdown
Under the ULMO definitions, an attached carport is considered an accessory use only when at least 75 percent of it is open or unenclosed; below that threshold it is treated as part of the principal building. Accessory uses must observe the required setbacks on Table 3 unless specifically excepted. That distinction matters because enclosing the sides of a carport can convert it into enclosed floor area subject to the principal-building setbacks and a building permit. Placement in a required bufferyard is prohibited. Cities within the county set their own carport standards, so confirm whether the ULMO, the Southwest Performance Zoning Ordinance, or a municipal code governs your lot.
Violations & Fines
Enclosing or relocating a carport into a required setback or bufferyard without a permit is a zoning violation subject to County enforcement.
