Kansas City Building Permit Exempt Work Guide

Kansas City lists several types of work that do not require a building permit, including some small sheds, low retaining walls, fences, and low decks.

Permit takeaway

Kansas City says no building permit is required for certain one-story detached accessory buildings up to 200 square feet, fences, and platforms or decks not exceeding 30 inches above grade when other limits are met.

Zoning and placement

Permit-exempt work may still need to comply with zoning, setbacks, easements, right-of-way, and other code requirements.

Building and trade review

Retaining walls up to four feet may be exempt unless they support surcharge, impound flammable liquids, or are adjacent to a public right-of-way.

Call before applying when

Call before building if the shed is near 200 square feet, the deck is near 30 inches above grade, the wall supports soil or a driveway, or the project is near public right-of-way.
