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 application4. Permit fees vary with the project's construction cost rather than a single flat amount10. 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 version11. Contact Dyer County Building & Zoning for permit and setback information before construction12.

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 appeals12. Completed forms may be sent to the office at 1910 Pioneer Rd., Dyersburg, TN 38024 or emailed to [email protected]12. 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 meeting4. An appeal requires a fee when the completed form is submitted, although the amount is not established in the reviewed county information4.

Does Dyer County have zoning?

Dyer County has a zoning resolution and an official zoning map, and permitted uses depend on the parcel's mapped district25. Setbacks also vary by district and use, so a setback from one residential district should not be carried over to another parcel without confirmation3. In the cited residential districts, dwellings and accessory buildings together may cover no more than 30% of the lot, but other uses can have different limits13. The county's cited residential height provisions generally allow buildings up to 35 feet without increased side yards and cap them at 65 feet, while accessory buildings are limited to two stories14. Ask Building & Zoning to identify the district and applicable dimensional table before settling a site plan12.

How do septic permits work in Dyer County?

A Tennessee Septic System Construction Permit is required before installing a subsurface sewage system or repairing a faulty one in Dyer County7. TDEC directs applicants not to begin dirt work or construction, including a building pad, before the permit is issued15. After installation, the applicant or installer notifies the Division of Water Resources, which inspects each system for compliance with the permit and regulatory requirements16. Dyer County asks applicants to have the sewage permit before submitting the county building-permit application4. For local assistance, the TDEC Jackson Environmental Field Office lists Dyer among its served counties and provides a septic-inquiry line at 731-441-559317. Only about 5.6% of county soils are rated without severe limitations for a conventional drain field, so make the site evaluation an early contingency18.

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 onsite12. Tiny houses are addressed by the county zoning materials, but their placement still depends on the parcel's zoning district5. Where a manufactured dwelling, mobile home or tiny house is allowed, the unit must connect to public gas, electric, water and sewer; if water or sewer is unavailable, it must use a septic system and/or well approved by TDEC8. We also could not confirm a general countywide minimum dwelling size, so request the rule for the specific district and structure type from Building & Zoning12.

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

  1. Ask Dyer County Building & Zoning to confirm the parcel's zoning district, allowed residential use and applicable setbacks23.
  2. Secure the 911 address and apply for the required TDEC septic permit before dirt work or construction begins415.
  3. Submit the county building-permit application after the sewage permit and 911 address are in hand; the fee is based on construction cost410.
  4. If acting as your own builder, confirm that the state exemption fits a single residence for personal use that is not for sale, lease or rent9.
  5. Before installing an entrance on a state highway right-of-way, obtain the required TDOT driveway permit19.
  6. Arrange the required septic inspection after installation16.

What should you check before buying land in Dyer County?

Start with the official zoning map, because district boundaries control allowed uses and parcel-specific dimensional rules53. Test septic feasibility early: only about 5.6% of Dyer County soils are rated without severe limitations for a conventional drain field18. 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 standard20. Dyer County's effective property-tax rate is about 0.6%, and its median annual property-tax bill is about $9662122. The county averages about 51.7 inches of precipitation annually, while roughly 94.7% of its land has a slope of 15% or less2324.

Watch-outs

  • Do not submit the Dyer County building-permit application before obtaining the sewage permit and 911 address4.
  • 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 buildable18.
  • Dyer County's RV-occupancy, temporary-camping and general minimum-home-size rules remain unconfirmed; ask Building & Zoning about the specific parcel and proposal12.
