Do you need a building permit in Greenville, MS?

Greenville requires the building inspector to issue a building permit before construction, reconstruction, renovation, demolition, structural excavation or filling, and development for a use without a building begins.1 Greenville building permit applications require a plat, dimensional sketch or scaled plan, so prepare the proposed layout before applying.1 Mississippi’s owner-builder exemption concerns residential-builder licensing for work on an owner’s own residence; the exemption does not waive a Greenville building permit or other local requirements.9 Ask the city Building Inspector to identify the inspections and residential occupancy approvals needed for your project.

Who issues building permits in Greenville, and how do you apply?

The Greenville Planning Department lists a Building Inspector and Planning/Zoning Director and can be reached at 662-378-1548.4 The city’s Planning Development page provides a building permit application and separate electrical, mechanical, plumbing and gas permit forms.4 Ask the Building Inspector which applications fit your work and request the current fee schedule before setting a construction budget. The city also provides an Application for Certificate of Business Occupancy; that business form does not establish the residential occupancy procedure.11 We could not confirm Greenville’s residential inspection schedule; ask the Building Inspector when to request each inspection.

Does Greenville have zoning, lot-size and setback rules?

Greenville has zoning regulations in Appendix B of its city ordinance.2 Ask the city Planning/Zoning Director to confirm the parcel’s district, permitted residential use and front, side and rear setbacks before choosing a house footprint. In Greenville’s A-1 Residential District, the table gives a minimum lot-area range of 1 to 3 acres for the specified conventional housing, mobile-home subdivision and individual mobile-home categories where public approved sewer is unavailable.7 The A-1 rule requires 3 acres where the soil test fails to show satisfactory percolation, with additional Washington County Health Department specifications.7 Treat the district’s lot-area rule and MSDH’s wastewater approval as separate checks.76

How do septic permits and off-grid sanitation work in Greenville?

MSDH administers onsite wastewater systems inside Greenville when a private system is used, and requires a permit for installation of a new system and the associated water meter.36 MSDH offers soil and site evaluations that produce a Permit/Recommendation suitable for installation.5 Washington County’s soils rated not limited for conventional septic drain fields account for only 0.1% of the county; this countywide rating supports getting a site evaluation, not a conclusion that septic is impossible on a Greenville lot.12 Greenville wastewater, including gray water, must be piped to sewer or septic and cannot be discharged onto the ground, into ditches or into bodies of water.10

Can you live in an RV, tiny home or manufactured home in Greenville?

We could not confirm permission to live in an RV or tiny home on a private Greenville lot; ask the city Planning/Zoning Director about permanent occupancy and temporary living during construction before buying either dwelling. Greenville’s zoning regulations are the starting point for that parcel-specific answer.2 Mississippi’s rules for Pearl River Valley Water Supply District campgrounds apply to those campgrounds and do not establish permission for RV living on private Greenville land.13 A manufactured home sited in Mississippi and installed on or after July 1, 2009 must undergo the state installation inspection before occupation, with necessary local and state approvals obtained before installation.14 Ask city Planning separately whether the proposed home is allowed in the parcel’s zoning district.

What are the steps to building a home in Greenville?

  1. Ask Greenville Planning to confirm the zoning district and proposed use against the city’s zoning regulations.2
  2. Confirm sewer availability; if the lot needs septic, apply to MSDH for its soil and site evaluation and wastewater approval.35
  3. Check flood hazard status with city Planning: Greenville requires residential lowest floors at or above base flood elevation where data exists in designated flood hazard areas.8
  4. Submit the plat, dimensional sketch or scaled plan and obtain the city building permit before starting the covered work.1
  5. Ask the Building Inspector for the project’s inspection sequence and residential occupancy requirements before scheduling construction.

For a property outside city limits, use the Washington County guide to find the county building and zoning contact; the county Planning Department handles county land-use and development questions.15

Watch-outs

  • A Greenville lot in a designated flood hazard area can require elevation measures even when the proposed residential use fits the zoning district.82
  • We could not confirm Greenville’s accessory dwelling, temporary RV occupancy or tiny-home occupancy rules; ask the city Planning/Zoning Director before committing to a second dwelling or a construction-site living arrangement.4
  • MSDH does not require a septic inspection for a real-estate transaction but recommends one; consider requesting an existing-system inspection before buying a Greenville home with septic.16

Unanswered questions are usually a sign that Greenville publishes no rule on the point, not that none exists. Washington County’s page lists the county offices to call.
