ADU Permit Requirements in City of Spring Hill, KS
The City of Spring Hill Community Development Department issues all building, electrical, plumbing, and mechanical permits within incorporated city limits. Spring Hill straddles the Johnson County / Miami County line (most of the city is in Johnson County); the city issues permits for BOTH portions within city limits regardless of county. Kansas has no statewide residential building code, so adoption is local: Spring Hill adopted the 2006 IRC, 2006 IBC, and 2005 NEC, along with the 2016 Zoning Ordinance. This is notably older than surrounding jurisdictions (Johnson County unincorporated and Miami County both use 2018 IBC/IRC). IECC Climate Zone 4A, 36-inch typical frost depth. Kansas has NO state contractor licensing; contractors working in Spring Hill must be licensed through the Johnson County Contractor Licensing Program (913-715-2233, cls.jocogov.org, 111 S. Cherry Suite 1000 Olathe KS 66061) for parcels in the Johnson County portion, or the Miami County Contractor Licensing Program (913-294-4145, 201 S. Pearl Suite 201 Paola KS 66071) for parcels in the Miami County portion. Owner-builders may pull their own permits for their primary residence (cannot be built for sale or lease; cannot occupy before Certificate of Occupancy). Planning and building are combined under Community Development; a 9-member Planning Commission (7 city residents, 1 unincorporated Johnson County, 1 unincorporated Miami County) advises on development. Spring Hill lies in the Hillsdale Lake watershed; Hillsdale Lake has a TMDL for eutrophication (nutrients), and the city enforces Chapter 19 Stormwater and Chapter 20 Sewer System Benefit Area ordinances plus Chapter 17 Floodplain Regulations (Ordinance 2009-12, effective 4/23/2009). For UNINCORPORATED parcels at a 66083 address outside city limits, permits are issued by Johnson County Building Codes Department (north side) or Miami County Building Code Services (south side).
