Property inside Huntsville is different: city land and structures must follow the applicable zoning district, and the city requires a Certificate of Zoning Compliance before issuing a building permit4.
Who do you call with building or zoning questions in Madison County?
Madison County's department listing does not identify a dedicated building, planning or zoning office, which is why the county building-permit answer remains worth confirming.
Madison County's department listing does not identify a dedicated building, planning or zoning office, which is why the county building-permit answer remains worth confirming1. Start with the Madison County Clerk at the courthouse in Huntsville for county-government questions that have no published administering department2. Madison County also lists a Road and Bridge Department for county-road matters and a combined addressing and floodplain office for addressing and floodplain questions2. For land inside Huntsville, use the city's zoning process because zoning compliance must be reviewed before a city building permit is issued4.
Does Madison County have zoning?
Madison County appears not to administer countywide zoning in unincorporated areas, but we could not confirm the absence of zoning in an express county ordinance or statement.
Madison County appears not to administer countywide zoning in unincorporated areas, but we could not confirm the absence of zoning in an express county ordinance or statement1. The City of Huntsville does have zoning: city property is divided into districts, permitted and conditional uses depend on the district, and the official zoning map determines a property's current zoning4. Huntsville also requires a Certificate of Zoning Compliance before a building permit is issued4. We could not confirm a minimum home size, general building setback, lot-coverage limit or building-height limit for unincorporated land; ask the County Clerk before fixing a site plan2.
How do septic permits work in Madison County?
First determine whether public sewer is available: Arkansas requires a home or business to connect when the building's sewer exit is within 300 feet of public-sewer access on the owner's property or an adjacent street or alley.
First determine whether public sewer is available: Arkansas requires a home or business to connect when the building's sewer exit is within 300 feet of public-sewer access on the owner's property or an adjacent street or alley6. Otherwise, the Arkansas Department of Health or its authorized agent approves the onsite-wastewater application5. The system must be inspected and approved, and the owner must obtain a Permit for Operation before use5. Application-review fees run from $30 for a structure up to 1,500 square feet to $150 for one over 4,000 square feet; alteration, repair or extension review costs $30, and garages, carports and porches do not count toward residential square footage9. Only about 8.1% of county soils lack severe limitations for a conventional drain field, so arrange the site and soil evaluation before choosing the house location10.
Can you live in an RV or tiny home on your land in Madison County?
We could not confirm a rule allowing or prohibiting long-term RV or tiny-home occupancy on a private parcel in unincorporated Madison County.
We could not confirm a rule allowing or prohibiting long-term RV or tiny-home occupancy on a private parcel in unincorporated Madison County. Confirm the parcel's status and current practice with the Madison County Clerk before moving in or relying on an RV during construction2. A parcel with 3 or more RV, tiny-house-on-wheels or mobile-home spaces is regulated as a park when placement or maintenance services are provided for a fee11. In such a park, a tiny house on wheels is treated as a mobile home when plumbed and inspected under the 2018 Arkansas Plumbing Code, and as an RV otherwise11. Those park rules do not settle occupancy of one RV or tiny home on private land.

- Design to the 2021 Arkansas Fire Prevention Code, including its building and residential codes3.

- Pay the application-review fee before Part 1 of the permit application is issued, then begin construction within 1 year or have the permit revalidated9.
- Have the septic system inspected and obtain its Permit for Operation before use5.
- For access, ask the Road and Bridge Department about a county road; a state-highway driveway needs ARDOT approval2,8.
What to check before you buy land in Madison County
Soils: only 8.1% of Madison County's land lacks severe limitations for a conventional septic drain field, while 56.3% of the county sits at 15% slope or less, so a flat-looking lot can still need an engineered septic system.
Soils: only 8.1% of Madison County's land lacks severe limitations for a conventional septic drain field10, while 56.3% of the county sits at 15% slope or less10, so a flat-looking lot can still need an engineered septic system. Water: the state onsite-wastewater rule requires at least 100 feet between a septic system and a domestic water well6; private domestic wells are not shown to need a Department of Health construction permit the way public and semi-public wells do13. Flood: Madison County's addressing and floodplain office handles floodplain questions for the county2. Access: a driveway onto a state highway needs its own Arkansas Department of Transportation permit, separate from anything the county requires8. Taxes: Madison County's effective property tax rate runs about 0.4%, with a median annual property tax bill near $70210.
Watch-outs
- Madison County has no official statement on minimum dwelling size, setbacks, lot coverage or building height for unincorporated land; treat these as unconfirmed and check with the County Clerk's office, not as unregulated2.
- Long-term RV and tiny-home living on a private unincorporated parcel remains unconfirmed; Arkansas regulates qualifying RV and tiny-house-on-wheels parks, but that does not answer single-parcel occupancy11.
