Unincorporated Coahoma County, Mississippi requires a building permit for a home, and the county Planning Department reviews zoning and setbacks before the permit is issued12. Septic paperwork comes from the Mississippi State Department of Health and must reach the county before building-permit approval34. A homeowner may pull the permit for work on the homeowner's own residence, but that licensing exemption does not waive county permits or inspections56.

Do you need a building permit in Coahoma County, Mississippi?
Yes. New residential construction in unincorporated Coahoma County requires a county building permit1. Before issuance, the county process calls for an address when needed, state wastewater paperwork, zoning and setback approval, plans, a tax parcel ID, and payment of the electrical, gas and plumbing permits2. Projects larger than 5,000 square feet require one stamped architectural-plan copy; other projects call for two scaled drawings2. Payment is by check or money order rather than cash2. The homeowner or contractor must schedule each county inspection at least 48 hours in advance8. A homeowner may act as general contractor on the homeowner's own residence under Mississippi's licensing exemption, but the county permit and inspection process still applies65.
Who handles Coahoma County building permits and inspections?
Start with the Coahoma County Planning Department at 71 Sunflower Avenue in Clarksdale, (662)624-9300 or [email protected]11. The county Building Official can be reached at (662) 645-0657 for building-plan review12. The county's published sequence requires zoning and setback approval before permit issuance, and the Building Official coordinates required inspections28. Coahoma County publishes fee schedules, but the amount depends on the project: the residential new-construction valuation basis is $78 per heated square foot, while the materials list different $95 commercial and $65 miscellaneous reinspection charges13. Ask Planning which schedule applies before preparing payment because the county accepts checks or money orders and does not accept cash for these permits2.
Does Coahoma County have zoning?
Yes. Coahoma County maintains zoning regulations administered by its Planning Department7. The county rules described here govern unincorporated Coahoma County; incorporated municipalities may administer their own requirements10. In the A-1 Agricultural district, the minimum lot area is 43,560 square feet, minimum frontage at the building setback line is 150 feet, and the front, side and rear dimensions are 40 feet, 30 feet on each side and 50 feet respectively10. Those figures are district-specific, so do not apply the A-1 table to a parcel until Planning confirms its zoning classification1011. Coahoma County's published materials do not confirm a countywide agricultural exemption, minimum dwelling size, lot-coverage limit or building-height limit; ask Planning for the current rule tied to the parcel11.
How do septic permits work in Coahoma County?
The Mississippi State Department of Health handles individual onsite wastewater permitting for Coahoma County3. A wastewater permit is required for a new onsite system and for a permanent water-meter application, and the county requires the state permit or recommendation before issuing the building permit4. Apply through the state wastewater program or call 1-855-220-0192 for help14. Only 6.3% of county soils are rated without severe limits for a conventional septic drain field, so make the soil and site evaluation an early contingency rather than assuming a conventional layout will work15. A permanent water meter requires a permanent sewage-disposal solution, and the state may refer a property within 1 mile of a sewer line for connection16. Household wastewater and gray water cannot be discharged onto the ground, into a ditch or into a body of water17.
Can you live in an RV or tiny home in Coahoma County?
Coahoma County zoning applies to unincorporated parcels, but the county materials do not confirm a general rule for long-term RV living, temporary camping or tiny-home occupancy on private land711. Ask the Planning Department whether the proposed unit is an allowed dwelling in the parcel's district and what permit, foundation, utility and occupancy conditions apply11. A new manufactured or mobile home has a clearer path: the county requires a permit before the home is moved onto the lot, requires state wastewater documentation, and will not authorize electricity without the permit9. An existing wastewater system also requires a licensed installer's affidavit addressing function and safety for that manufactured-home process9. Any occupied unit still needs lawful wastewater disposal because Mississippi prohibits discharging household wastewater or gray water on the ground, into ditches or into bodies of water17.
Building a home in Coahoma County: what are the steps?
- Ask the Planning Department to confirm the parcel's zoning district, setbacks and whether an E911 address is needed211.
- Apply to the Mississippi State Department of Health for the wastewater permit or recommendation and have the soil evaluated before construction214.
- Submit the state wastewater paperwork, plans and tax parcel ID to the county, then pay the required trade permits and building-permit charges by check or money order2.
- If access needs a culvert, contact the Coahoma County Road Department so it can determine the location and size18.
- Schedule county building inspections at least 48 hours ahead8.
- For a project using an individual wastewater system, deliver the installer maintenance-agreement affidavit, installer affidavit and state final-inspection report before the county issues the certificate of occupancy19.
What should you check before buying land in Coahoma County?
Confirm the parcel's jurisdiction and zoning district first, because the county rules described here apply to unincorporated land and A-1 dimensions should not be assumed for another district10. Make the purchase contingent on a workable wastewater plan: only 6.3% of county soils are rated without severe limits for a conventional drain field15. Check legal road access and culvert needs with the county Road Department, which determines culvert location and size for county development access18. If the driveway connects to a Mississippi state highway, a state access permit is required for a new driveway or alteration20. For a private well, a groundwater-withdrawal permit applies when the surface casing is at least 6 inches in diameter, subject to exclusions21. Coahoma County's effective property-tax rate is about 1.2%, and the median annual property-tax bill is about $1,0712223.
Watch-outs
- Coahoma County's published commercial and miscellaneous schedules show different reinspection fees, so ask Planning which schedule applies to your project1311.
- The county materials do not confirm private-land RV occupancy, temporary camping or a special tiny-home rule; get a parcel-specific answer from Planning before buying or placing a unit711.
- A county certificate of occupancy involving an individual wastewater system depends on installer affidavits and the state final-inspection report19.
