Building permits, zoning and land rules in Greene County, Missouri

Yes. Unincorporated Greene County requires a permit to construct, alter, repair, move, demolish or change a structure¹. Permits also cover installation, alteration, repair or removal of electrical, gas, mechanical and plumbing systems, wastewater-system or sewer-line work, and disconnection from septic to connect to city sewer¹. Greene County applies the 2012 International Codes, the 2011 National Electrical Code with adopted amendments and county wastewater standards¹. Recorded property owners may obtain permits in their own names, or authorized agents may apply with proof of ownership, but this does not waive the permit, code, inspection, zoning or wastewater requirements¹. A certificate of occupancy is issued only after required inspections are approved and other departmental requirements are met¹. Unlike most counties around it in Missouri, Greene County requires a county building permit¹.

Greene County Resource Management’s Building Regulations office issues building permits for unincorporated Greene County at 940 N Boonville Ave, Room 305, Springfield, MO 65802; call (417) 868-4015¹. Commercial submittals require sealed design documents, 5 plan sets, an application and the plan-review fee; initial comments should be available in 10 to 15 working days, and the building permit issues after all reviewers approve¹. Inside city limits, Springfield, Rogersville and Walnut Grove issue their own building permits; Republic requires a city commercial change-of-occupancy permit for the specified existing-building or infill work^6,7,8,9. Septic permits in unincorporated Greene County come through Building Regulations under the Environmental Division’s rules³; inside Rogersville, the city superintendent issues private sewage disposal permits¹⁰.

Every property in unincorporated Greene County is zoned by the county; county zoning stops at city limits². Inside Springfield, Rogersville, Walnut Grove, Willard, Strafford and Ash Grove, the city’s own zoning code applies instead^{11,12,13,14,15,16}. Lot division depends on the district: the A-R option allows tracts of at least 5 acres and RR-1 at least 3 acres, both requiring rezoning². More than 3 lots requires a surveyor-prepared plat and county review; parcels of at least 10 acres may use the stated no-plat exception unless a new public road is dedicated². Ask Planning and Zoning for the parcel's setbacks, height, dwelling-size and applicable coverage rules².

Greene County's Environmental Division administers onsite wastewater rules, while permit applications go to Building Regulations³. A permit is required for a new onsite system and for repair or replacement of an existing system; systems not connected to public sewer remain subject to county permitting and design rules³. The application needs a building-permit application, a site evaluation by a qualified soil scientist, and a site plan and system design by an approved professional; commercial, non-residential and mechanical systems require a professional engineer³. Only 8.6% of Greene County soils rate “not limited” for a conventional drain field; that does not rule out septic, but makes site evaluation essential before fixing the house site⁵. We could not confirm whether every new, repaired or replaced system receives a construction inspection; ask Environmental what inspections the proposed system will require³.

Greene County allows one recreational vehicle to be stored at specified residential locations, but no permanent or temporary living quarters may be maintained in it while parked or stored there⁴. Authorized travel trailer parks are limited to C-2 districts and must meet county sanitary, building-code, utility, area and yard conditions⁴. A tiny home on wheels counts as a recreational vehicle under the same rule¹⁷. A tiny home that qualifies as a county-defined manufactured home and is smaller than 1,000 square feet may be used as an accessory residence in an A-1 Agriculture District¹⁸. Manufactured homes used as dwellings are limited to A-1 or MH-1 districts, previously approved mobile-home parks, or mobile-home subdivisions; modular homes meeting site-built code requirements are allowed in any zoning district⁴. A park model home of 400 square feet or less may be a primary use only in an approved travel trailer park⁴. We could not confirm a general temporary-camping rule outside an approved park or a general minimum dwelling size, so take the unit specifications and parcel number to Planning and Zoning before buying².

1. Confirm the parcel's jurisdiction, zoning district, setbacks and proposed use with Planning and Zoning^2,4.
2. Determine whether public water and sewer are required; Greene County requires both for urban-style development, including lots of 10,000 square feet or less².
3. If onsite wastewater is needed, obtain the site evaluation and system design before applying through Building Regulations³.
4. Check the flood map: any activity in the Special Flood Hazard Area on the FEMA maps for unincorporated Greene County needs a floodplain development permit, with plans and the fee submitted to the Environmental Division³.
5. Apply before building a driveway or culvert on county right-of-way¹⁹.
6. Submit the building-permit application and plans to Building Regulations; the recorded owner may be the permittee¹.
7. Schedule building inspections the day before; same-day inspections are unavailable¹. Start work within six months and maintain inspections every six months to keep the permit valid, except for the stated demolition inspection exception¹.

Confirm the zoning district and any division history before assuming acreage can be split; tract sizes and plat requirements vary by district and proposal². Get a soil evaluation before counting on conventional septic because only 8.6% of Greene County soils rate “not limited” for a conventional drain field⁵. Agricultural practices in unincorporated Greene County remain subject to sinkhole-use standards, floodplain standards and onsite wastewater regulations⁴. Any activity in a mapped Special Flood Hazard Area needs a floodplain development permit³, and an agricultural pond needs one too if it lies there, or a grading permit if soil leaves the property³. Verify road ownership: a county-right-of-way driveway requires a county permit before work, while access on Missouri transportation right-of-way follows the state process^19,20.
