Do you need a building permit in Stone County, Mississippi?
Yes. Stone County requires a permit for any structure over 200 square feet, regardless of its purpose1. The same requirement covers a prefabricated building that you purchase and place on your property1. Stone County warns that permit fees double when work begins before the permits are approved, so contact Planning and Building before site work or delivery1. The department says it permits and inspects structures under the 2003 International Building and Residential Codes4. Mississippi's statewide code framework separately says counties and municipalities had to enact uniform building codes unless they opted out before November 30, 20147. For a parcel inside Wiggins, ask the city rather than assuming the county process controls, because the county's own notice says the city has zoning2.
Who issues Stone County building permits, and how do you reach them?
The Stone County Planning & Building Department is the first stop for building permits and inspections4. The office is at 311 Court Street, Suite C, Wiggins, MS 39577; call 601-928-2810 or email build@stonecountyms.gov4. The department also assigns E-911 addresses, reviews commercial site plans and new subdivisions for Board of Supervisors approval, and enforces the county flood-damage-prevention ordinance4. Ask the department which application packet fits the project and whether separate electrical, plumbing, mechanical, mobile-home or floodplain paperwork is needed, because the county's permit application lists those permit types8. Stone County has a published fee schedule, but confirm the current charge with the office before budgeting; the county expressly directs applicants to call for clarification1.
Does Stone County, Mississippi have zoning?
Unincorporated Stone County currently has no zoning as it pertains to land use2. That does not make rural land rule-free: Stone County still enforces adopted building codes, and construction, alterations or installations may need permits2. Commercial and industrial sites must receive approval from the Stone County Board of Supervisors2. The City of Wiggins has zoning, so confirm whether a parcel lies inside city limits before relying on the county's no-zoning statement2. Land divided into subdivision lots is different: where a lot relies on an individual well and septic system, the minimum lot size is 1.5 acres, and building setbacks are 30 feet in front, 20 feet on the side and 30 feet in the rear910. We could not confirm setbacks for a single parcel outside a subdivision, or minimum dwelling size, lot coverage, building height or accessory dwellings; ask Planning and Building about the specific parcel and proposed use4. County records also do not establish a general private-land rule for long-term RV or tiny-home occupancy, so treat those uses as unanswered until the department responds4.
How do septic permits work in Stone County?
The Mississippi State Department of Health administers Stone County's on-site wastewater program, including technical work for individual septic systems and individual water supplies3. Start with the state's online wastewater application; the county Planning and Building page likewise directs applicants online for a percolation-test permit or recommendation4. For local contact information, the Stone County Health Department is at 211 North Critz Street in Wiggins and can be reached at 601-928-529311. Mississippi does not require a septic inspection as part of a real-estate transaction, although inspection is recommended, so ask for one before buying land that already has a system12. Only about 33% of Stone County soils are rated without severe limitations for a conventional septic drain field, so make the site evaluation an early contingency rather than designing the house first6. Mississippi does not recognize gray water as a separate waste stream; wastewater must go to a central sewer or septic system rather than onto the ground, into a ditch or into water13.
Can you live in an RV or tiny home in Stone County?
We could not confirm a Stone County rule that generally allows or prohibits living in an RV on private land, temporary camping on private land, or occupancy of a tiny home. Ask the Stone County Planning & Building Department about the parcel, the proposed duration and the required utility setup before buying or moving a unit4. No land-use zoning in unincorporated Stone County does not remove the county's adopted building-code and permit requirements2. Stone County does regulate RV parks, meaning four or more RVs offered to the public for lease or rent: an RV park needs at least one acre, board approval of its site plan, and each RV must sit at least 30 feet from a roadway right-of-way14. A tiny structure over 200 square feet requires a county permit, and a prefabricated building placed on the property is subject to the same rule1. Sanitation remains a separate constraint: Mississippi requires wastewater to enter a central sewer or septic system, and gray water cannot be discharged onto the ground, into ditches or into bodies of water13. A permanent water connection also requires an available permanent sewage-disposal solution15.
What are the steps to build a home in Stone County?
- Confirm whether the parcel is in unincorporated Stone County or inside Wiggins, because the city has zoning while unincorporated county land currently does not2.
- Call Stone County Planning & Building before work begins to identify the building, trade, floodplain and address paperwork for the project4.
- Apply to the Mississippi State Department of Health for the on-site wastewater evaluation and septic paperwork when public sewer is unavailable3.
- Finalize the building location and plans after the wastewater site evaluation, especially because only about 33% of county soils lack severe limits for a conventional drain field6.
- Obtain the county permit before construction or delivery of a qualifying prefabricated building; fees double if work starts before approval1.
- If access connects to a state highway, obtain the state driveway permit required for a new driveway or alteration16.
What should you check before buying land in Stone County?
Confirm jurisdiction first: unincorporated Stone County currently lacks land-use zoning, while Wiggins has zoning2. Check the permit path with Planning and Building, including floodplain review and the E-911 address process that the department handles4. Make a septic evaluation part of the purchase contingency because only about 33% of county soils are rated without severe limitations for a conventional drain field6. If a well is planned, Mississippi requires a groundwater-withdrawal permit for wells with a surface casing diameter of 6 inches or more, subject to exclusions17. Verify legal road access and determine whether the entrance meets a county road or a state highway; new or altered driveways on state highways require a state permit16. Stone County is about 81% wooded and roughly 17% federally owned, useful context when checking timber, boundaries and neighboring public land1819. The countywide effective property-tax rate is about 0.6%, with a median annual bill near $9912021.
Watch-outs
- No land-use zoning in unincorporated Stone County does not mean no permits: structures over 200 square feet require county approval, and adopted building codes still apply12.
- Stone County doubles permit fees when work begins before approval, so secure the permit before construction or delivery1.
- Private-land RV living, temporary camping and tiny-home occupancy remain unconfirmed; ask Planning and Building about the exact parcel and sanitation plan4.
