Summary
In Rapid City's LDR-1 low density residential district, no main building may exceed 2.5 stories or 35 feet in height, and accessory buildings are capped at 15 feet, under Rapid City Municipal Code § 17.10.060.
No main building shall exceed 2½ stories or 35 feet in height, except as provided in § 17.50.260. Accessory buildings shall not exceed 15 feet in height.
Full Breakdown
260. 5-story/35-foot ceiling applies to the primary dwelling on the lot, while any detached garage, shed or other accessory structure is held to a flat 15-foot limit, less than half the main building allowance. 260 carves out an exception, meaning a project that qualifies under that supplementary regulation (the code's off-street parking and height exception provisions for specific structures) can exceed the base 35-foot cap without a variance. 050(G), so Community Development's Planning Division checks height, setback distance and lot coverage together during building permit review.
The height rule traces to the prior code's Appendix A, Article IV, § 2(E) and has not been amended by a later ordinance, unlike the neighboring setback and lot coverage subsections, which were updated as recently as Ordinance 6616 in 2024.
Violations & Fines
A main building that exceeds 2.5 stories or 35 feet, or an accessory building over 15 feet, without qualifying for the § 17.50.260 exception is a zoning violation. Community Development's Planning Division flags an over-height design at permit review before a foundation is poured, and Code Enforcement can act on a complaint against a structure already built too tall; the owner must either reduce the height to conform or obtain a variance from the Board of Adjustment through the procedure referenced in § 17.54.030 before the city will issue a certificate of occupancy.
