Kirkwood, MO Building Setbacks & Zoning: Structure Height Limits (2026)

Kirkwood measures and caps building height district by district in Table 48-5, adopted under § 25-48(c). 5 stories, with no infill finished first floor height rule listed. 5-story cap but layer on an infill finished-first-floor-height requirement under § 25-48(c)(3)(i) for lots on blocks where more than 40% of the block face is already built out. 5 stories; R-MM matches the 3-story multifamily allowance at 35 feet. R-6 and R-7 planned districts do not use the flat table figure at all: R-6 height is set under § 25-48(e)(2), and R-7 height is capped in the planned-district ordinance itself, though § 25-34(h)(5)(iv) caps any R-7 development at the lesser of 5 stories or 70 feet absent a different limit in that ordinance.

Section 25-46(j) defines how height is actually measured: for R-1 through R-4, R-MM, and single-family R-5 homes, it runs from the average finished grade at the front of the building to the highest point, covering all roof types; chimneys and flues may exceed the cap under the building code, and church spires and steeples are exempt from the district maximum entirely.
