Do you need a building permit in Hancock County, Mississippi?

In unincorporated Hancock County, Planning & Zoning issues building and trade permits for residential and commercial construction, renovations, additions, heating, plumbing, electrical work and mobile homes1. Hancock County follows the 2018 International Building/Residential Codes for the work it administers3. Hancock County publishes a construction permit fee schedule15. A project valued at $1,000 or less pays no permit fee unless an inspection is required, in which case each inspection costs $15; starting work before obtaining a required permit doubles the applicable fee12. A homeowner building a single-family primary residence may perform electrical, plumbing or mechanical work, but must obtain the individual permits; Hancock County charges no fees for those homeowner-performed trade permits10.

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

Hancock County Planning & Zoning is the office serving unincorporated land for building, electrical, plumbing, heating and mobile-home permits, plan review and zoning, at 854 Highway 90, Suite A, Bay Saint Louis, MS 39520, phone 228-467-415716. The department also handles subdivision applications under published county subdivision regulations17. Subdivision lots without sewer collection and treatment must be at least 50 feet wide and 100 feet deep, while irregular residential lots must also contain at least 7,500 square feet; health and zoning requirements can demand more13. Applicants use the applicable residential or commercial forms, while applications involving the zoning ordinance go to the Planning Commission; an applicant seeking a place on the commission agenda must return the application and fee by the Friday before the meeting18. Inside Diamondhead, the city Building Department issues building permits; MSDH still handles onsite wastewater systems48.

Does Hancock County have zoning?

Hancock County Planning & Zoning administers zoning for unincorporated land and forwards zoning applications to the Planning Commission219. Inside Diamondhead, the city sets zoning, while MSDH remains the onsite wastewater authority58. Ask county Planning & Zoning to confirm an unincorporated parcel's district, allowed use, residential setbacks and dwelling standards; we could not confirm a complete dimensional schedule2016. Subdivision minimums do not override stricter zoning lot-area or width requirements13. For RV parks, the front setback is 25 feet, or 50 feet along a state or federal highway; side buffers and rear setbacks depend on adjoining districts and rights of way, and permanent structures must meet the zoning ordinance's standards21. Those RV park setbacks do not establish setbacks for an ordinary homesite21.

How do septic permits work in Hancock County?

The Mississippi State Department of Health's South Region handles onsite wastewater permits and inspections in Hancock County67. Before constructing or placing a residence or building that may need an onsite wastewater system, submit a Notice of Intent to MSDH; the approved Permit/Recommendation is also required for a water-service connection9. Sewer providers have first right to serve a property, and MSDH may require a rejection letter before proceeding with a septic application22. Contact the MSDH wastewater call center at 1-855-220-0192 for the soil and site evaluation and inspection arrangements; design-based systems require inspection and approval before final approval237. Only 3.7% of Hancock County soils are rated not limited for a conventional drain field; that does not mean septic is impossible, but a site evaluation should precede the house layout24. Household wastewater, including gray water, must go to central sewer or septic rather than the ground, a ditch or a body of water25.

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

Hancock County does not allow an RV in a permitted RV park to be used as a residential dwelling or permanent abode; occupancy or a stationary stay beyond 30 days in a three-month period is treated as permanent occupancy and prohibited14. That park rule does not answer whether someone may live in an RV on an ordinary residential or agricultural parcel outside a permitted RV park, which we could not confirm; ask Planning & Zoning before buying land for that use1416. We also could not confirm a county rule specific to tiny-home occupancy or a countywide minimum dwelling size; Planning & Zoning should identify the parcel's district and dwelling standards2616. A mobile home has a defined permit path: the permit costs $101 and requires a perk test or utility will-serve letter and proof of a wind zone 2 or greater rating11. Factory-built homes installed in Mississippi must also pass the state installation inspection before occupation27.

Building a home in Hancock County: the steps, in order

  1. Ask Hancock County Planning & Zoning to confirm the parcel's zoning district, allowed use and dimensional standards before design begins2616.
  1. Determine whether a sewer provider can serve the parcel; MSDH may require the provider's rejection letter before proceeding with a septic application28.
  1. Submit the MSDH Notice of Intent before constructing or placing a building that may need septic, and obtain the Permit/Recommendation for the onsite system and water connection9.
  1. Complete the applicable residential or commercial county forms and include an elevation certificate if the property is in a Special Flood Hazard Area1829.
  1. Submit the building-permit package and fee to Planning & Zoning before work starts; the county publishes the fee schedule1512.
  1. Obtain final wastewater approval before final power approval, and provide a final elevation certificate when the property is in a flood zone3029.

What to check before you buy land in Hancock County

Annual precipitation is about 64.8 inches, and severe drought occurs in about 5.8% of years3132. The county is flat and wooded: 100% of land is at a slope of 15% or less, and 72.2% is wooded3334. Confirm the zoning district, sewer availability and flood status before closing; Hancock County participates in the National Flood Insurance Program and uses current FEMA flood maps262235. Residential construction in a Special Flood Hazard Area requires an elevation certificate29. A new or altered driveway connecting to a Mississippi state highway requires a state permit36. Typical home insurance costs about $2,964 a year, while the effective property-tax rate is about 0.7% and the median annual property-tax bill is about $1,485373839.

Watch-outs

  • Subdivision minimums do not settle a parcel's zoning requirements; ask Planning & Zoning whether the district requires more lot area or width1316.
  • Permitted RV parks prohibit occupancy or a stationary stay beyond 30 days in a three-month period, while the rule for RV living on an ordinary private parcel remains unconfirmed; ask Planning & Zoning before assuming an RV can serve as a dwelling1416.
  • Only 3.7% of Hancock County soils are rated not limited for conventional drain fields; the rating does not rule out septic, so get an MSDH site evaluation before buying24.
