Unincorporated Morgan County, Alabama does not currently require a general building permit for a house, garage, or barn1. The county still requires three other permits for new development: a floodplain determination, a septic (onsite sewage) permit, and a driveway permit, and none of them is optional1. Morgan County also has no general zoning ordinance, so it sets no minimum home size, setbacks, or use restrictions on unincorporated land2. Only 18.7% of the county's soil is rated free of severe limits for a conventional septic drain field, so budget time for a site evaluation before you count on a standard system3.

Do you need a building permit in Morgan County, Alabama?
Unincorporated Morgan County, Alabama does not currently require a general building permit for a house, garage, or barn1. The Morgan County Engineer's own page states that development in the county requires permits in three areas only, floodplain, sewage disposal, and driveway access, and describes none of them as optional1. Alabama law does let a county commission adopt a general building code and inspectors for unincorporated areas under Ala. Code § 34-14A-12, so this could change, but no official Morgan County page shows that the county has exercised that authority10. Construction inside a mapped floodplain is the exception: it still needs a floodplain development permit and periodic inspection from the Morgan County Engineer's Office118.
Who handles floodplain, septic and driveway permits in Morgan County, and how do you reach them?
Morgan County has no building department because unincorporated land needs no general building permit1. Floodplain permits, the county's subdivision regulations, and utility or driveway permits within county road right-of-way are handled by the Morgan County Engineer's Office at 580 Shull Road, Hartselle, AL 35640, phone 256-773-5297, email [email protected]8. That office administers the Morgan County subdivision regulations and administers the Morgan County flood ordinance8. Septic tank and onsite-sewage applications go through the Morgan County Health Department's environmental office at 3821 Hwy. 31 South, Decatur, Alabama 35603, phone 256-340-656312.
Does Morgan County have zoning?
Morgan County has no general zoning ordinance for unincorporated land2. The county's own subdivision regulations refer to a zoning resolution "when they exist," language that only makes sense if the county has none today2. Alabama law does not give counties broad, general land-use authority the way it lets some counties zone by local law, and the state's own county-commissioners handbook names only a short list of counties, such as Baldwin, Russell, Shelby, and Jefferson, that have created that kind of local authority13. Because Morgan County has no zoning ordinance, it sets no minimum dwelling size, no minimum lot size, no setbacks, no lot-coverage limit, and no building-height limit on unincorporated land5. That same gap means Morgan County does not restrict living in an RV, tiny home, or manufactured home, or temporary camping, on unincorporated land through zoning5. Two state rules still apply to the structures themselves regardless of zoning: a manufactured home must be installed by an installer certified by the Alabama Manufactured Housing Commission14, and a park-model trailer under 400 square feet counts as temporary living quarters, not a permanent dwelling15.
How do septic permits work in Morgan County?
Every onsite sewage system for residential use in Morgan County needs a Permit to Install from the local health department before construction begins1617. The Morgan County Health Department provides onsite-sewage and septic-tank applications and permits to the public1812. A floodplain determination must be obtained before applying for the sewage-disposal permit, because certain systems are not allowed in a flood-prone area16. Only 18.7% of Morgan County's soil is rated free of severe limitations for a conventional septic drain field, so expect the county's floodplain-then-septic sequence to often lead into a site evaluation for an alternative system3. Statewide, only a registered professional engineer may design the system where soil percolation is slower than 60 minutes or a shallow limiting zone is present, a common condition given how little of the county's soil is favorable17. Building before all required permits are in hand risks a $300 penalty under the county's own rule16.
Can you live in an RV or tiny home on your land in Morgan County?
Unincorporated Morgan County places no zoning restriction on living in an RV, tiny home, or manufactured home on your own land, because the county has no zoning ordinance to set that rule52. A recreational park-model trailer, defined statewide as no more than 400 square feet of gross trailer area in setup mode, counts as temporary living quarters rather than a permanent dwelling, and Alabama's rule does not itself authorize placing one for site, septic, or floodplain purposes in Morgan County15. A manufactured home used as a residence anywhere in Morgan County must still be installed by an Alabama Manufactured Housing Commission-certified installer and meet the Commission's uniform standards, and occupying a noncompliant unit is a misdemeanor carrying a civil penalty of up to $50014. Any RV, tiny home, or manufactured home with its own wastewater system still needs a septic permit from the Morgan County Health Department the same as a house1612, and if the parcel sits in a mapped floodplain, a floodplain permit from the County Engineer's Office comes first118.
Building a home in Morgan County: the steps, in order
- Confirm you don't need a general building permit: unincorporated Morgan County has none today, though this could change if the county commission ever adopts a building code under state law110.
- Get a floodplain determination from the Morgan County Engineer's Office early; it is required before you can even apply for a septic permit168.
- If the site is in a mapped Special Flood Hazard Area, obtain the county's floodplain development permit and expect periodic inspections during construction118.
- Apply for an onsite sewage disposal permit with the Morgan County Health Department's environmental office and wait for the Permit to Install before starting construction1612.
- If you're building or improving your own one- or two-family home to live in, you likely qualify for Alabama's owner-builder exemption from residential contractor licensing, as long as you supervise all the work yourself and don't sell within a year619.
- Hire a state-licensed water well driller if you need a well; the driller, not the landowner, files the Notification of Intent and a Certification of Completion within 30 days of finishing9.
- Apply to ALDOT with Form BM-111 if the driveway will connect to a state highway, or coordinate with the Morgan County Engineer's Office for other driveway and utility permits in county right-of-way208.
- Before covering any onsite sewage installation or closing out floodplain-related work, confirm what completion documents each office needs: Morgan County's own rule sets a $300 penalty for building before all required permits are in hand16.
What to check before you buy land in Morgan County
Water: Alabama does not regulate individual private wells directly outside coastal capture zones, so a domestic well in Morgan County needs a state-licensed driller but no separate landowner permit; the driller carries a $200 annual state license and must file a completion report within 30 days of finishing9. Soils: only 18.7% of Morgan County's soil carries no severe limitation for a conventional septic drain field, and any system still needs a floodplain determination before the septic permit is issued, so build in time for a site evaluation316. Flood: Morgan County requires a floodplain permit for most construction and can require a FEMA elevation certificate before it will issue a certificate of occupancy for work in a Special Flood Hazard Area218. Access: connecting a driveway to a state highway needs an ALDOT permit built to state standards, including a side-drain pipe at least 15 inches in diameter20. Taxes: Morgan County's effective property tax rate runs about 0.3%, with a median annual property tax bill of about $674, low even by rural-county standards2223. Setting: at 215.9 people per square mile and about 19 miles from the nearest metro area, Morgan County is denser and more connected than most Bolthole Index counties, with 56.4% of its land wooded and severe drought in only about 5.8% of years24252627.
Watch-outs
- No official Morgan County page states whether the county has adopted a building code under state law, so a countywide building-permit requirement could exist or change without notice; confirm current status with the Morgan County Engineer's Office before you build108.
- Morgan County's own materials describe a Permit to Install but do not state a general post-installation inspection requirement, so ask the Health Department's environmental office directly what inspection your system will need1612.
- No official Morgan County source addresses short-term rentals in unincorporated areas, so a buyer planning to rent should ask the County Engineer's Office or County Commission directly before assuming any use is allowed28.
