Do you need a building permit in Morgan County, Alabama?
Unincorporated Morgan County requires a Development Permit before construction or other development begins in a FEMA Special Flood Hazard Area or another county-designated flood hazard area1. We could not confirm a general county residential building-permit requirement outside regulated floodplains; ask the Morgan County Engineer's Office to check the parcel and proposed work2. Floodplain projects can require plans, elevations, utility-protection details, professional certifications and inspections during construction1011. Decatur, Hartselle and Priceville handle their own municipal building permits; the cited Hartselle provision concerns manufactured-home subdivisions, and Priceville's concerns subdivision development121314. Huntsville, mainly in Madison County but reaching into Morgan County, also issues its own building permits15. Septic applications remain with the Morgan County Health Department4.
Who handles floodplain development permits in Morgan County?
The Morgan County Engineer's Office handles the county flood ordinance, subdivision regulations and utility permits within county road right-of-way2. Reach the office at 580 Shull Road, Hartselle, AL 35640, 256-773-5297, or gbodley@morgancounty-al.gov2. For a new division of unincorporated land, the county administers subdivision review, although a municipal planning commission may control a development in its planning jurisdiction3. A plat within the Hartselle Planning Commission's jurisdiction needs commission approval before it is filed with the Morgan County Probate Judge's Office16. The Morgan County Health Department, not a city building office, is the county-level contact for onsite sewage and septic-tank applications417.
Does Morgan County have zoning?
We could not confirm whether unincorporated Morgan County has a current countywide zoning ordinance; ask the Morgan County Engineer's Office about the parcel's land-use constraints2. Alabama counties lack broad general land-use authority under general state law, but local laws and special statutory powers can authorize zoning and other controls18. Morgan County administers subdivision regulations and floodplain development controls in unincorporated areas31. Inside city limits, Decatur, Hartselle and Priceville have their own zoning rules192021. Hartselle's planning office handles zoning questions, and the city warns that recent amendments may not appear online2223. Municipal zoning does not replace the Morgan County Health Department's role in onsite-sewage applications4.
How do septic permits work in Morgan County?
The Morgan County Health Department administers onsite-sewage and septic-tank applications and permits throughout Morgan County4. A property not connected to public sanitary sewer needs a Permit to Install before a new onsite sewage system is built or an existing system is repaired; the installer must be licensed by the Alabama Onsite Wastewater Board5. If public sewer is unavailable, soil testing determines septic suitability, and unsuitable conditions may require an engineered system24. Only 18.7% of Morgan County soils are rated free of severe limitations for a conventional drain field, so make site review an early purchase contingency25. Call the Health Department before installation to schedule the required inspection, and obtain Approval for Use before occupying the building6. The environmental office is at 3821 Hwy. 31 South, Decatur, Alabama 35603, phone 256-340-656317.
Can you live in an RV or tiny home on your land in Morgan County?
We could not confirm private-land RV or tiny-home occupancy rules for unincorporated Morgan County; ask the Engineer's Office about the proposed site and the Health Department about sewage disposal217. A park-model tiny home is temporary living quarters for recreational, camping, travel or seasonal use under Alabama rules, not a permanent dwelling7. A manufactured home must be installed by an Alabama Manufactured Housing Commission-certified installer and meet the Commission's standards26. New or repaired onsite sewage systems require a Permit to Install, inspection and Approval for Use before building occupancy56. Regulated floodplain development requires county approval before work begins1. Inside Decatur, Hartselle or Priceville, ask the city's planning office about occupancy because municipal zoning applies192021.
What are the steps to building a home in Morgan County?
- Establish the parcel's jurisdiction: Decatur, Hartselle and Priceville have municipal zoning and building-permit rules192021121314.
- Ask the Morgan County Engineer's Office for a floodplain determination and any subdivision review that applies132.
- Obtain the floodplain Development Permit before starting regulated work10.
- For a property off public sewer, complete site review and obtain the Health Department's Permit to Install before septic construction or repair245.
- If using the owner-builder licensing exemption, personally supervise construction of the home intended for your own use8.
- For a well, use a licensed driller who files the pre-work notice and completion certification9.
- Schedule septic inspection, obtain Approval for Use, and submit required final floodplain certifications before occupancy627.
What should you check before buying land in Morgan County?
Start with jurisdiction and subdivision status: unincorporated parcels can face county subdivision review, while a municipal planning commission may have authority in its planning area3. Ask the Morgan County Engineer's Office whether the project needs a floodplain Development Permit and what fees apply12. Make septic suitability a contract contingency because only 18.7% of county soils are rated free of severe limits for a conventional drain field25. For a private well, use a licensed driller who files Alabama's required notice before work and completion certification within 30 days afterward9. We could not confirm a county rule for a new residential driveway connection; ask the Engineer's Office about county-road access2. Access onto an Alabama state highway requires an ALDOT turnout permit28. Morgan County's effective property-tax rate is about 0.3%, and the median annual property-tax bill is about $6742930.
Watch-outs
- County zoning and private-land RV occupancy remain unconfirmed; ask the Morgan County Engineer's Office before treating unincorporated land as unrestricted2.
- Hartselle warns that recently adopted zoning amendments may not yet appear in its online compilation, so confirm the current ordinance with the city23.
- Beginning January 1, 2027, Alabama residential home builders must follow the applicable state or local residential building code31.

- Share of soils USDA rates "not limited" for a conventional septic drain field (SSURGO). A strict rating: the median county is about 6% and a tenth of counties are 0%, so a low figure means most lots need a site evaluation or an engineered system, not that septic is impossible.
