Blue Springs, MO Building Setbacks & Zoning: Lot Coverage Limits (2026)

The Unified Development Code assigns a maximum building coverage percentage to every residential building type listed in Section 405.020's Building Type Standards, so the ceiling depends on which building type is built rather than which zoning district applies. Estate-lot detached houses, the largest-lot option, are held to 25% lot coverage; neighborhood-lot detached houses rise to 40%; small-lot and compact-lot detached houses reach 70%; duplexes on a standard lot and multi-building apartment complexes are capped at 60%; and row houses, the most compact attached type, top out at 80%.

Whichever percentage applies, the footprint of any garage, ADU or other accessory structure on the same lot counts toward that same lot's total coverage figure, per Section 405.060(A)(3)(g), which separately limits any detached accessory structure to no more than 10% of the total lot area unless another standard specifically provides otherwise. Community Development staff check the applicable building-type percentage, plus any accessory-structure footprint, against the recorded lot area during site plan and building permit review before construction begins. Exceeding the applicable percentage requires either redesigning the structure to fit within the cap or seeking relief through the variance process under Section 403.060, since the UDC provides no administrative exception once a building type's line in the table is set.
