Blaine, MN Accessory Structures: Carport Rules (2026)

Blaine's code does not single out 'carports,' so a carport is treated as an accessory building or structure under the City's accessory-building rules (recodified Section 100-5, Accessory buildings, structures, uses). That means a zoning permit ($75) is required if the carport exceeds 120 square feet or is built on a poured slab or footings, and structures over 200 square feet are regulated as residential garages. Accessory buildings, including attached and detached garages and the structures that count alongside them, are limited to a combined total of 1,000 square feet in the R-1 single-family district, with typically two accessory buildings allowed per property. Setbacks follow the accessory-building schedule (1-foot side/rear for 0-120 sq ft and 5 feet for 121-200 sq ft in R-1), a minimum 3-foot separation from other structures applies, and the carport may not sit in a drainage or utility easement. Architectural compatibility requirements also apply: siding, roof material, roof pitch, and style must be compatible with the home, and roof height cannot exceed the home's roof height. Because a freestanding carport in a front yard or covering a driveway raises additional setback and design questions, confirm placement with Blaine Planning staff before building.
