Does Prairie Village, Kansas have zoning, and what does it cover?
Prairie Village zones land inside its own city limits, and its zoning regulations include R-1A and R-1B residential districts with neighborhood design guidelines2. We confirmed only those two districts; the full district list and map were not available to us4. Johnson County's separate zoning applies only to unincorporated land outside any city9.
We could not confirm Prairie Village's rules on RV living, tiny homes, manufactured homes, minimum lot size or minimum home size. Ask the10 before you buy or plan a build.
Do you need a building permit in Prairie Village, and who issues it?
Prairie Village requires a building permit to build an accessory structure1 and for all residential additions10. The City of Prairie Village Codes Department issues them10. A drainage permit from the city's Public Works Department must be on file first, all contractors must be licensed with the city, and additions of 600 square feet or more need a tree protection and removal plan1.
The city's handouts cite the 2018 international codes7. We could not confirm whether an owner-builder exemption exists inside the city; the handout requires city licenses for all contractors1.
What are the rules for a garage or shed in Prairie Village?
Prairie Village permits one major accessory building of up to 576 square feet, and it cannot sit in a utility easement5. The building may be at most 20 feet tall or no taller than the main structure, whichever is less6. It must sit at least 60 feet from the front property line and 20 feet from a street side lot line5. Side and rear setbacks start at 3 feet, and a building above 10 feet must be set back one third of its height5. Building coverage may not exceed 30 percent11.
What does a building permit cost and what plans does Prairie Village require?
The city calculates the building permit fee from the value or square footage of the work when it approves the permit, so no flat amount is published in the handouts we reviewed8. Plans must be sealed by a Kansas registered design professional, and the site plan must rest on a boundary survey12. Applications go through the city's online portal10.
