Do you need a building permit in Greene County, Missouri?

Yes. Unincorporated Greene County requires a permit to construct, alter, repair, move, demolish or change a structure15. Permit coverage also extends to electrical, gas, mechanical and plumbing work, as well as wastewater-system or sewer-line repair and replacement5. Greene County uses the 2012 International Codes, the 2011 National Electric Codes with amendments and county wastewater standards5. A permit becomes invalid if work does not begin within six months of issuance or if six months pass without an inspection5. Missouri's farm-structure exemption concerns county fire ordinances; it does not establish a general building-permit exemption8.

Who issues Greene County building permits, and how do you reach them?

Greene County Resource Management's Building Regulations office issues construction permits for unincorporated Greene County5. The office is at 940 N Boonville Ave, Room 305, Springfield, MO 65802, and its phone number is (417) 868-40155. Building Regulations routes submitted plans to relevant county reviewers before issuing a permit5. The office schedules inspections, and its page directs applicants to call the day before rather than expect a same-day inspection5. For parcels inside municipal limits, begin with the city because municipalities handle zoning within their limits9.

Does Greene County have zoning?

Yes. All property in unincorporated Greene County is zoned, while property inside a municipality is governed by that municipality29. Planning and Zoning handles land-use and development questions for unincorporated areas10. Ask the office to confirm the district and permitted uses for the exact parcel before relying on a listing description10. Complete county rules for RV occupancy, tiny homes, minimum dwelling size, setbacks, lot coverage and building height could not be confirmed. Give Planning and Zoning the parcel number and a specific description of the proposed dwelling or use before buying or finalizing plans210.

How do septic permits work in Greene County?

Greene County requires a permit for a new onsite wastewater system and for repair or replacement; applicants obtain the permit from Building Regulations3. Materials include a site evaluation from a qualified soil scientist and a site plan and system design prepared by an eligible professional3. Commercial, non-residential and mechanical systems require a professional engineer, and installers need county and Missouri certifications3. Only 8.6% of county soils rate free of severe limits for a conventional drain field, so resolve soil suitability early7. Missouri describes possible exemptions for some lots, but ask Building Regulations about the specific parcel rather than assuming one113.

Can you live in an RV or tiny home on land in Greene County?

We could not confirm a Greene County rule that generally allows residential or long-term RV occupancy, temporary camping or tiny-home occupancy in unincorporated areas. Planning and Zoning handles permitted-use questions, so give that office the parcel number and describe the proposed unit and occupancy before buying land10. Building Regulations publishes temporary-use and manufactured-home materials, but complete occupancy standards were not confirmed; ask whether the unit needs a building permit, temporary-use approval or another review5. All unincorporated property is zoned, so a rural address does not answer whether a particular unit is allowed2.

What are the steps to build a home in Greene County?

  1. Confirm zoning and the proposed use with Planning and Zoning10.
  2. If public sewer is unavailable, obtain the soil evaluation, site plan and system design needed for the onsite wastewater permit3.
  3. Ask Environmental about flood risk because activity in a Special Flood Hazard Area requires a floodplain permit12.
  4. Contact Highway before county-road access work; a driveway or culvert on county right-of-way requires a permit6.
  5. Submit construction plans and the building-permit application to Building Regulations5.
  6. Schedule inspections and keep the permit active; a certificate of occupancy follows approved inspections and completion of other departmental requirements513.

What should you check before buying land in Greene County?

Get a soil evaluation before counting on conventional septic: only 8.6% of county soils rate free of severe limitations for a conventional drain field7. Confirm zoning because all unincorporated property is zoned and municipal rules apply inside city limits29. Check flood risk because activity in the Special Flood Hazard Area requires a permit12. Verify road ownership: county right-of-way driveway work goes through Highway, while driveway work on Missouri transportation right-of-way requires a state permit614. About 94.2% of the land has a slope of 15% or less, but slope does not resolve soil or flood concerns15. The typical home value is about $260,119, and the median annual property-tax bill is about $1,469 at an effective rate near 0.7%161718.

Watch-outs

  • An owner-builder exemption is not confirmed; ask Building Regulations whether an owner may pull the permit and perform the proposed work45.
  • RV, temporary-camping and tiny-home occupancy rules could not be confirmed; ask Planning and Zoning about the parcel and Building Regulations about the unit105.
  • A driveway or culvert on county right-of-way requires a county permit, while access on Missouri transportation right-of-way follows the state permit process614.

Missouri rules that apply here

    “Because fire and building codes are adopted at the local level in Missouri”

    effective date: 2025-08-28
