Do you need a building permit in Lee's Summit, MO?

Lee's Summit requires a separate city building permit for each regulated building or structure before construction, enlargement, alteration, repair, remodeling, moving, conversion or demolition.1 Residential construction follows the 2024 International Residential Code with city additions, amendments and exceptions.9 Homeowners may obtain building permits for their primary residence, but that permission does not exempt the work from building-code compliance.7 Lee's Summit's final inspection must occur after the permitted work is complete and before occupancy, including moving furniture into the house.10

Who issues building permits in Lee's Summit, and what do they cost?

Lee's Summit Development Services accepts building permit applications online or at its office on the first floor of City Hall; roofing applications must go through CityView.11 Contact Development Services at 816.969.1200 or [email protected] for building permit questions.12 City building permit fees depend on project cost and work type, with a $50 minimum and a flat $50 charge for re-roofing or demolition.13 Standard inspections and plan reviews are included, but water tap, right-of-way, sanitary sewer development and miscellaneous fees may also apply.13

Does Lee's Summit have zoning, lot-size rules and setbacks?

Lee's Summit's Unified Development Ordinance regulates zoning and subdivisions inside city limits.2 Development Services offers free telephone zoning verification using the property's address, legal description or parcel number.14 In the AG Agricultural District, the minimum lot is 10 acres for either one or two dwelling units under the same ownership; RDR Rural Density Residential requires a minimum 1-acre lot.65 The standard R-1 minimum lot size is 8,400 square feet.15 AG and RDR front setbacks are 100 feet on major streets and 50 feet on other streets, or as established by existing homes on the same side of the street; side and rear setbacks are 50 feet.16

How do septic permits work inside Lee's Summit?

Lee's Summit requires residential properties within 150 feet of public sewer to connect; nonresidential properties within 300 feet must connect.8 Where public sewer is unavailable, Jackson County Public Works must approve the private sewage system before Lee's Summit issues the building permit.17 Under Jackson County's onsite wastewater program, permitted system construction must be inspected before backfill, and the county provides that service to municipalities other than Kansas City, Independence and Lake Lotawana.18 Ask the Jackson County On-Site Wastewater Specialist at 816-881-4515 which private sewage-system approval your project needs.19 Missouri's possible single-family septic exemptions are not a substitute for the city's stated requirement to obtain county approval.2017

Can you live in an RV or tiny home in Lee's Summit?

We could not confirm a rule allowing residential RV occupancy on a private lot in Lee's Summit; ask Development Services about the proposed address and use before relying on an RV as housing.14 Lee's Summit requires single-family homes to have at least 720 square feet, so a smaller proposed single-family tiny home would not meet that minimum.4 We could not confirm a separate tiny-home occupancy rule; ask Development Services to identify the applicable dwelling classification and zoning approval.14 A temporary certificate of occupancy for a permitted building may be issued only when the occupied portion is safe, with a validity period set by the city.21

Building a home in Lee's Summit: what are the steps?

  1. Ask Lee's Summit Development Services to verify the parcel's zoning using the address, legal description or parcel number.14
  2. Resolve sewer service: connect where the city's distance rule requires it, or obtain Jackson County's private sewage-system permit before the city building permit when public sewer is unavailable.817
  3. For work in a regulatory floodplain, submit a Floodplain Development Permit application to city Public Works for review and approval.2223
  4. Apply for the city building permit through Development Services and obtain approval before regulated construction begins.111
  5. Complete required construction inspections and obtain the final approved inspection before occupancy.1021

What should you check before buying land in Lee's Summit?

Lee's Summit floodplain development permits cover more than houses: earthwork, fill, excavation, tree clearing or planting, sheds and pools also require approval within a regulatory floodplain.22 An Elevation Certificate may be required, and floodway work may need a No Rise Certificate.22 We could not confirm whether Lee's Summit requires a separate private well permit; ask Development Services before planning a well.12 Missouri regulates professional well construction and pump-installation work through contractor permits, while state guidance allows landowners to install their own well or pump under applicable law and rules.24 For property outside city limits, use the Jackson County guide: county zoning responsibility applies to unincorporated land rather than city parcels.25

Watch-outs

  • Lee's Summit's single-family minimum of 720 square feet applies even when a small home is proposed on a large lot.4
  • Private sewage-system approval from Jackson County must come before the Lee's Summit building permit when public sewer is unavailable.17
  • We could not confirm a general agricultural building-permit exemption inside Lee's Summit; ask Development Services about the specific structure.12
