Shed Permit in Kansas City, MO
Permit Summary
Do You Need a Shed Permit?
Exemptions
A building permit is not required for a one-story detached accessory building used as a tool or storage shed, playhouse, garage, carport, or similar use when the projected roof area does not exceed 200 square feet. Permit-exempt work must still comply with the applicable Zoning and Development Code and Building and Rehabilitation Code.
Attached Shed Rules
The 200-square-foot building-permit exemption applies only to detached accessory buildings. A shed attached to a house or other principal building does not qualify for that exemption and is reviewed as an addition or alteration under the applicable residential permit process.
Shed Use Rules
The permit exemption covers one-story detached tool and storage sheds and similar accessory uses. Residential accessory structures must be subordinate to the principal use, be on the same lot as the principal building, and be constructed with or after the principal building. A change to a use that is not accessory storage can trigger different zoning or building requirements.
Zoning & Placement Rules
Zoning Rules
All sheds must comply with zoning even when building-permit-exempt. In the standard residential districts covered by IB122, an individual detached storage shed is limited to a 200-square-foot footprint. AG-R and R-80 districts allow accessory buildings up to 8,000 square feet under the district exception. Accessory structures must remain subordinate to the principal use and on the same lot. A larger shed in a district subject to the 200-square-foot zoning limit requires Board of Zoning Adjustment relief before it can be approved.
Setback Rules
For residential garages and sheds covered by IB122, a detached accessory structure may not be in a front or street-side yard and may not be closer to the street than the principal building. Minimum rear and interior-side setbacks are 1 foot 6 inches, and the structure must be at least 10 feet from other principal or accessory buildings on the same lot. Recorded building lines, easements, or other site restrictions can require greater separation.
Maximum Height Rules
IB122 limits a detached residential storage shed to 10 feet in height in the standard residential districts it covers. For a roof slope greater than 1 inch per foot, shed height is measured as the average of the top-plate height and roof-ridge height. In AG-R and R-80 districts, accessory buildings may be up to 35 feet high.
Lot Coverage Rules
The combined footprint of all detached accessory buildings and structures may not exceed 40 percent of the actual rear yard under the residential accessory-structure rules in IB122. The separate individual shed-size limit and any district-specific exceptions also apply.
Special Area Rules
Additional approvals can apply based on the site. Development within Kansas City's regulated FEMA 100-year floodplain plus the City's one-foot freeboard area requires a Floodplain Development Permit. Work on designated historic landmarks or in historic or certain neighborhood conservation overlay areas may require a Certificate of Appropriateness before a building permit can be issued.
Construction Requirements
Foundation Rules
Kansas City's small detached-shed exemption does not prescribe a special foundation type; permit-exempt work must still comply with applicable code. When a shed requires plan review, the plans must show the proposed foundation system and applicable footing or foundation information. Nonprescriptive engineered foundation or structural features require sealed design information and calculations.
Fire Separation Rules
Under IB122, when a detached accessory building is less than 5 feet from a property line, the wall along that property line generally requires a 1-hour fire-resistance rating; the bulletin provides an exception for detached accessory structures with projected roof area of 200 square feet or less that are exempt from a building permit. Exterior walls 3 to 5 feet from a property line are limited to 25 percent openings. Projections closer than 5 feet require 1-hour protection on the underside, and projections closer than 2 feet are limited to 4 inches.
Permit & Review Path
Permit / Review Path
A qualifying one-story detached shed with projected roof area of 200 square feet or less follows the building-permit-exempt path but must still meet zoning and building-code requirements. A detached shed over 200 square feet requires a building permit and plan review through CompassKC; in standard residential districts where zoning limits an individual shed to 200 square feet, Board of Zoning Adjustment relief is also required. An attached shed does not use the detached-building exemption. Residential plan review is subject to the City's published one- and two-family review target.
Trade Permits & Professional Design
Trade Permit Rules
Separate electrical, plumbing, mechanical, or other trade permits may be required if those systems are installed or altered in the shed. Kansas City requires permits before most electrical, plumbing, and heating/ventilating work, and permitted trade work is subject to inspection. Owner-occupants may obtain certain trade permits for work they personally perform on a single-family dwelling or accessory structure; otherwise City licensing requirements apply.
Professional Design Rules
Kansas City's one- and two-family residential submittal guidance does not generally require an architect or engineer seal for prescriptive residential plans. Engineered features that do not conform to the prescriptive 2018 International Residential Code path require appropriately sealed drawings and calculations. Site-specific floodplain or other specialized conditions can also require professional certification or design.
What You Need Before Applying
Requirements
A shed must comply with Kansas City's building and zoning codes even when no building permit is required. Confirm whether the shed qualifies for the one-story detached accessory-building exemption, verify zoning placement and dimensional limits, and obtain a building permit through CompassKC when the exemption does not apply. Separate zoning, floodplain, historic, or trade approvals may be required for some sites or scopes.
Required Documents
For a permitted residential shed, submit the required plans electronically through CompassKC, including a site plan or survey and construction drawings showing the proposed work. Kansas City generally requires a sealed, staked land survey for new structures; an accessory structure more than 10 feet from a property line may use a site plan instead when the location can be established from City GIS or vetted property documents. Engineered features require sealed drawings and calculations as applicable.
