Can my Arkansas city allow a fourth-story addition on my house?

Not under the IRC. Buildings exceeding three stories must be designed under the IBC with the appropriate construction type, fire-resistance ratings, and egress provisions.

Does the state set a maximum height for commercial buildings?

The IBC sets maximum heights and areas based on construction type and occupancy classification. There is no fixed statewide cap; sprinklers and construction type can allow taller structures.

Full Breakdown

Arkansas adopts the 2021 International Residential Code and 2021 International Building Code through the State Fire Marshal under A.C.A. 12-13-104 and the Arkansas Fire Prevention Code. The IRC applies to detached one- and two-family dwellings and townhouses up to three stories above grade plane. Buildings exceeding IRC scope must comply with the IBC, which sets height and area limitations based on construction type and occupancy. While local zoning ordinances commonly set lower height limits for specific districts, no Arkansas city may permit construction that violates the state-adopted code minimums for fire safety, structural integrity, or means of egress.

Violations & Penalties

Construction exceeding code height limits without proper classification may be denied permits, ordered halted, or required to be modified before occupancy.
