Blaine, MN Building Setbacks & Zoning: Structure Height Limits (2026)

Blaine's zoning code sets a hard ceiling on how tall a home can rise in its most common residential district. Sec. 109-120(11), governing the Single-Family (R-1) Zone, states that the "maximum building height shall not exceed 2½ stories or 30 feet, whichever is less," meaning a design that would technically fit within 2½ stories but pushes past 30 feet in elevation is still barred, and vice versa. The same section requires every single-family lot to carry a garage of at least 400 square feet with no dimension under 20 feet, and it caps the height of garage or accessory building access doors at 10 feet, a separate vertical limit aimed at oversized overhead doors rather than the roofline itself.

The 2½-story/30-foot formula recurs with the same wording in Blaine's other low-density districts, including the Agricultural (AG), Farm Residential (FR) and Residential Estate (RE) zones, each under its own numbered standards section, so the cap is not unique to R-1 but is the baseline height rule across the city's single-family and estate-lot zoning. Height is measured and enforced by the community development department's zoning administrator as part of building permit review under Sec. 101-7(c), which requires the building official to confirm conformity with the development code, including height, before issuing any permit for new construction or a substantial remodel.
