Lee's Summit, MO Building Setbacks & Zoning: Setback Rules (2026)

040 of the Unified Development Ordinance requires every principal building to sit back from street rights-of-way and property lines by no less than the distances in Table 6-3. 5-foot side yards, and a 30-foot rear yard. AG and RDR lots need 100 feet from a major street or 50 feet on other streets, plus 50-foot side and rear yards. RP-1 and RP-2 use a 50-foot front yard (20 feet for the building and 25 feet for a front-facing garage, or 20 feet for a side-entry garage), a 5-foot side yard, and a 20-foot rear yard (4 feet for an alley-entry garage).

Downtown-style districts run tight: CP-1 and CBD allow a 0-to-5-foot front and side yard with no rear yard required, while TNZ permits a 0-to-15-foot front yard. The front-yard figure drops another 5 feet anywhere the garage is accessed from an alley. 5-foot minimum on the other lines. 060 lets irregular, flag, and narrow lots average their rear-yard depth to a 30-foot (R-1) or 20-foot (RP-1) minimum, subject to Director approval, and lets sills, cornices, chimneys, and eaves project up to 36 inches into a required yard. 530, which requires clear and convincing evidence of practical difficulty or unnecessary hardship tied to the land itself, not personal financial hardship.
