Pasco, WA Accessory Structures: Carport Rules (2026)

Pasco does not publish a carport-specific rule. A carport is regulated as a residential accessory structure under PMC 25.65.030 (Permitted accessory uses), the same category that covers detached garages, sheds, and similar ancillary buildings. The same chapter permits detached single-family residential garages up to 15 feet in height and 1,000 square feet in area, with larger or taller structures on lots over 12,000 square feet possible only by special permit (which may allow extra height and up to 200 additional square feet of floor area). Pasco's development standards require a minimum of 6 feet between a habitable structure and a non-habitable structure such as a carport or garage. Accessory structures must meet the setback and dimensional standards of the underlying zoning district set out in Title 25, and the Planning Division publishes a Quick Zoning Reference Table to help residents place a detached garage, shop, or similar structure on a residential lot. A building permit is generally required to construct a carport, and any electrical work requires a separate permit. Because the applicable setbacks and height limits depend on your specific zoning district and whether the carport is attached to the house or detached, confirm your zone, required setbacks, and permit needs with the City of Pasco Planning Division before building.
