Summary
Kansas City exempts detached single-family homes, duplexes, and townhouses from the IBC automatic sprinkler mandate, but builders must offer buyers the option to install one.
903.2.8, Exception. An automatic sprinkler system is not required in a detached single family dwelling, a detached two-family dwelling (duplex), or in an attached single-family dwelling (townhouse), where under the scope of this Article.
A builder of a detached one- or two-family dwelling or townhouse shall offer to any purchaser on or before the time of entering into the purchase contract the option, at the purchaser's cost, to install or equip fire sprinklers in the dwelling or townhouse.

Full Breakdown
Kansas City's local amendment to the adopted International Building Code (Sec. 18-40, amending IBC § 903.2.8) exempts detached single-family dwellings, detached two-family dwellings (duplexes), and attached single-family townhouses from the automatic fire sprinkler system requirement. Builders of these home types must still offer the buyer, before contract signing, the option to install fire sprinklers at the buyer's own cost: a disclosure duty tied to Mo. Rev. Stat. § 67.281. Multi-family and commercial buildings remain subject to the full IBC sprinkler mandate.
Violations & Fines
No sprinkler installation violation exists for exempt home types since none is required. A builder who fails to offer the purchaser the sprinkler option before contract execution is out of compliance with the Sec. 18-40 disclosure requirement.
