New one- and two-family homes and townhouses in unincorporated Meigs County, Tennessee require a state residential building permit, and county compliance review may also apply1,2.

RV occupancy and minimum lot area depend on the zoning district5.
Do you need a building permit in Meigs County, Tennessee?
Yes.
Yes. New one- and two-family dwellings and townhouses in unincorporated Meigs County require a state residential building permit1. Meigs County Planning & Zoning also issues a compliance permit for the county's zoning, subdivision, mobile-home and floodplain regulations2. The state permit does not replace zoning approval, floodplain review, septic or sewer approval, grading approval or electrical permits10. Tennessee applies the 2018 International Residential Code and 2018 International Energy Conservation Code under the state program7. Detached garages, sheds, barns and other detached structures not used for living do not need the state residential permit; manufactured or modular homes generally do not, though custom site work does1. The available facts do not establish Meigs County's commercial-code requirements, so ask Planning & Zoning what review applies to a nonresidential project2.
Who issues Meigs County building permits, and how do you reach them?
The Tennessee State Fire Marshal's Office administers the residential building permit and inspection program used in unincorporated Meigs County.
The Tennessee State Fire Marshal's Office administers the residential building permit and inspection program used in unincorporated Meigs County1. A state residential permit can be purchased online through CORE or from a local Issue Agent7. Meigs County Planning & Zoning separately issues the county compliance permit and enforces zoning, subdivision, mobile-home and floodplain regulations2. Reach Planning & Zoning at 423-334-2565, email planningandzoning@meigscountytn.org, or visit 345 N. Main Street, Decatur, TN 373222. Ask the Compliance Coordinator what to submit because a complete county application checklist and review timeline could not be confirmed2. State residential permit fees depend on construction cost, cover required inspections and one free reinspection, and additional reinspections cost $100 each6.
Does Meigs County have zoning?
Yes.
Yes. Meigs County Planning & Zoning enforces a Zoning Resolution, Subdivision Regulations, Mobile Home Regulations and Floodplain Regulations2. Minimum lot area varies by district and utilities: a detached home in R-1 or R-2 requires 15,000 square feet with public water and sewer, 20,000 square feet with public water only, or 25,000 square feet without public water5. A detached home in FAR requires 20,000 square feet with public water or 25,000 square feet without it, while WF lots require at least 3 acres5. TDEC or health requirements can require more land5,11. We could not confirm a minimum home size, setback schedule or tiny-home classification; ask Planning & Zoning for the parcel's district and current dimensional standards2.
How do septic permits work in Meigs County?
Tennessee's Department of Environment and Conservation, not Meigs County, handles septic permits, site evaluations and final inspections here.
Tennessee's Department of Environment and Conservation, not Meigs County, handles septic permits, site evaluations and final inspections here3. A septic permit is required to construct, modify or repair a system and should be obtained before dirt work or construction of the building pad begins4. Apply through the state portal or call the Chattanooga Environmental Field Office at (423) 634-5745 for septic permits and records3. After installation, the installer must arrange a final inspection before covering the system; TDEC issues a Certificate of Completion when the installation passes4. Only about 14% of Meigs County's mapped soils lack severe limitations for a conventional drain field, so a site evaluation can materially affect the buildable area and system design9. Subdivision lots using septic and public water generally need at least 20,000 square feet; without public water or sewer, they generally need at least 25,000 square feet, and the health authority may require more12.
Can you live in an RV or tiny home on land in Meigs County?
RV occupancy in Meigs County is not a countywide yes or no; the zoning district controls.
RV occupancy in Meigs County is not a countywide yes or no; the zoning district controls5. On a vacant lot in the R district, the county may issue a temporary-use permit for the permit holder's sole residence for no more than 6 continuous months, with placement and removal dates stated on the permit5. The FAR district permits travel trailers and travel-trailer parks subject to its area rules, any applicable park resolution, and septic and health requirements5. The Commercial district does not allow an RV as a permanent residence5. We could not confirm how Meigs County classifies a tiny home or what minimum dwelling size applies, so ask Planning & Zoning about the specific design, foundation, utilities and parcel district before buying or moving a unit2.
Building a home in Meigs County: the steps, in order
Ask Meigs County Planning & Zoning to identify the parcel's district, minimum lot area, floodplain status, subdivision issues and compliance-permit requirements.
- Ask Meigs County Planning & Zoning to identify the parcel's district, minimum lot area, floodplain status, subdivision issues and compliance-permit requirements2,5.
- Apply for the state residential building permit through CORE or a local Issue Agent before covered construction begins1,7.
- Apply to TDEC for the septic permit before dirt work or construction of the building pad, then preserve the approved disposal area4.
- Schedule state inspections for the foundation before pouring, rough-in and framing, and final construction; certain slab foundations require another inspection, and plumbing and mechanical inspections also apply6.
- Arrange TDEC's final septic inspection before the installer covers the system4.
- Provide written notice of public sewer service, a septic-permit application or use of an existing septic system before the electrical inspector processes new service13.
- If the driveway enters a state highway right-of-way, obtain the separate TDOT driveway permit14.
What should you check before buying land in Meigs County?
Confirm the zoning district, minimum lot area and floodplain status with Meigs County Planning & Zoning before relying on a listing's description of buildability.
Confirm the zoning district, minimum lot area and floodplain status with Meigs County Planning & Zoning before relying on a listing's description of buildability2,5. Order the septic site evaluation early because only about 14% of mapped soils lack severe limitations for a conventional drain field9. Check access jurisdiction as well: a driveway connecting to state highway right-of-way needs a TDOT permit, while we could not confirm a county-road driveway rule14. The county is about 59% wooded and about 56% of its land has a slope of 15% or less, so clearing and terrain can change the usable building envelope9. The median property-tax bill is about $727 per year at an effective rate near 0.4%, useful as countywide context rather than a quote for a particular parcel9. We could not confirm a private-well permit rule or an off-grid sanitation alternative; ask Planning & Zoning and TDEC before treating either as available2,3.
Watch-outs
- An R-district RV permit allows no more than 6 continuous months of occupancy and must state when the RV will be removed5.
- A state residential building permit does not replace the Meigs County compliance permit, septic approval, floodplain review or electrical permits2,10.
- Meigs County's tiny-home classification, minimum dwelling size, private-well requirements and county-road driveway rules could not be confirmed; ask Planning & Zoning before committing to a parcel or design2.
