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

City Code Section 11-602.2(1) sets the building-height standard for the Low-Density Residential-1 (LDR-1) district: the maximum height for a principal structure is 35 feet, and an accessory structure is capped at 20 feet or the height of the principal structure on the same lot, whichever number is lower. The Code makes the accessory limit a true ceiling rather than a target by adding that an accessory structure cannot exceed the height of the principal building at all, with a single carve-out for farm buildings related to an active farming operation.

Height standards vary by residential district under the same numbering scheme: LDR-2 principal structures are allowed 40 feet under Section 11-603.2(1), while Moderate-Density Residential structures reach 55 feet for principal buildings including attached garages under Section 11-604.2(3), showing the LDR-1 figure is the most restrictive of the residential tiers. The Chief Building Official reviews height compliance as part of the building permit process, and the height limit interacts with other LDR-1 standards, including the 35-foot minimum building width in Section 11-602.2(2) and the perimeter foundation requirement tied to the Minnesota State Building Code in Section 11-602.2(4).

Because the 20-foot accessory cap is measured against the principal structure's actual height rather than a flat number alone, a homeowner proposing a tall accessory building, such as a two-story detached garage, must first confirm the principal home's height to know the true ceiling that applies to the accessory structure.
