Do you need a building permit in Dyer County, Tennessee?

Yes. Dyer County requires a building permit for all new construction, including mobile and modular homes, as well as additions, alterations, demolitions and accessory buildings¹. The county says to obtain the sewage permit and 911 address before submitting the building-permit application⁵. Permit fees vary with the project's construction cost rather than a single flat amount¹¹. A narrow code provision also requires a previously purposed structure converted into a dwelling to meet the locally adopted 2015 International Residential Code provisions for existing buildings, or a later locally adopted version¹². The zoning resolution also describes a certificate of occupancy after final inspection, but makes that process conditional on adoption by the county court; ask Building & Zoning whether it applies to the project¹³¹⁴.

Who is the Dyer County building department, and how do you reach it?

Dyer County Building & Zoning handles county building permits, setback questions, Planning Commission submissions and zoning appeals¹⁵. Completed forms may be sent to the office at 1910 Pioneer Rd., Dyersburg, TN 38024 or emailed to afitzhugh@co.dyer.tn.us¹⁵. The Planning Commission meets on the second Thursday of each month, while the Board of Zoning Appeals meets on the second Tuesday; submissions for either are due 14 days before the meeting⁵. An appeal requires a fee when the completed form is submitted, although the amount is not established in the reviewed county information⁵.

Does Dyer County have zoning?

Dyer County administers local zoning through designated districts, and uses or dimensional requirements can vary by district or require approval on appeal². The official zoning map determines the parcel's district⁶. Setbacks also vary by district and use, so a setback from one residential district should not be carried over to another parcel without confirmation³. Residential lot minimums also depend on district and wastewater service: FAR permitted uses require at least three-fourths of an acre, while R-1 and R-2 dwellings require at least 10,000 square feet with public water and central sewer or 15,000 square feet with public water and septic; soil conditions may require more land¹⁶. In the cited residential provisions, buildings over 35 feet require larger side yards and may not exceed 65 feet, while accessory buildings may not exceed 2 stories¹⁷. Dwellings and accessory buildings in the cited residential districts may cover no more than 30% of the lot¹⁸. Ask Building & Zoning to identify the district and dimensional rules before settling a site plan¹⁵.

How do septic permits work in Dyer County?

Tennessee's state septic program, rather than Dyer County, handles permits for installing a subsurface sewage system or repairing a faulty one⁴. TDEC directs applicants not to begin dirt work or construction, including a building pad, before the permit is issued¹⁹. After installation, the applicant or installer notifies the Division of Water Resources, which inspects each system for compliance with the permit and regulatory requirements²⁰. Dyer County asks applicants to have the sewage permit before submitting the county building-permit application⁵. The TDEC Jackson Environmental Field Office lists Dyer among its served counties and provides a septic-inquiry line at 731-441-5593²¹. Only about 5.6% of county soils are rated without severe limitations for a conventional drain field, so make the site evaluation an early contingency²².

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

We could not confirm a general Dyer County rule allowing full-time RV occupancy or temporary camping on private land, so ask Dyer County Building & Zoning about the parcel and proposed duration before buying or moving an RV onsite¹⁵. Tiny houses are limited to places where the zoning district allows them and must meet county standards for a permanent foundation, conventional exterior and roof, removal of towing gear and height⁹. Tiny and manufactured homes must connect to public gas, electric, water and sewer; where water or sewer is unavailable, the unit must use a TDEC-approved well and/or septic system²³. Manufactured and mobile homes also have foundation or underpinning and exterior standards, with added rules on flood-hazard sites²⁴. We could not confirm a general countywide minimum dwelling size, so request the rule for the specific district and structure type from Building & Zoning¹⁵.

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

Ask Dyer County Building & Zoning to confirm the parcel's zoning district, allowed residential use, lot-area requirement and applicable setbacks²¹⁶³.
Secure the 911 address and apply through Tennessee's state program for the required septic permit before dirt work or construction begins⁵⁴¹⁹.
Submit the county building-permit application after the sewage permit and 911 address are in hand; the fee is based on construction cost⁵¹¹.
If acting as your own builder, use the state licensing exemption only for a single residence for your own use; Dyer County's building-permit requirement still applies¹⁰.
Before installing an entrance on a state highway right-of-way, obtain the required TDOT driveway permit²⁵.
Arrange the required septic inspection, then ask Building & Zoning whether the county's conditional final-inspection and certificate-of-occupancy process applies²⁰¹⁴.

What should you check before buying land in Dyer County?

Start with the official zoning map, because district boundaries control allowed uses, setbacks and minimum lot area⁶³¹⁶. Test septic feasibility early: only about 5.6% of Dyer County soils are rated without severe limitations for a conventional drain field, and some residential lot standards allow the required area to increase with soil conditions²²¹⁶. Confirm legal road access as well; a vehicle opening may be no wider than 30 feet under the county resolution, and access to a state or federal highway must meet the higher applicable standard²⁶. Dyer County's effective property-tax rate is about 0.6%, and its median annual property-tax bill is about $966²⁷²⁸. The county averages about 51.7 inches of precipitation annually, while roughly 94.7% of its land has a slope of 15% or less²⁹³⁰.

Watch-outs

Do not submit the Dyer County building-permit application before obtaining the sewage permit and 911 address⁵.
Only about 5.6% of Dyer County soils are rated without severe limitations for a conventional septic drain field, so confirm an approvable system before treating a lot as buildable²².
Dyer County's RV-occupancy, temporary-camping and general minimum-home-size rules remain unconfirmed; ask Building & Zoning about the specific parcel and proposal¹⁵.
The zoning resolution makes its certificate-of-occupancy process conditional on county-court adoption, so confirm the active final-inspection requirement before scheduling a move-in date¹³¹⁴.
