Sumner County Building and Codes, at 355 N. Belvedere Drive in Gallatin, is the building authority for unincorporated Sumner County. The county enforces the 2021 International Codes it adopted in 2023, and collects the Adequate Facilities Tax that gates new development — including, through a certificate requirement, permits issued by the cities.
The Adequate Facilities Tax is the feature to plan around. It is a per-square-foot privilege tax on new residential, commercial and industrial development under the 1999 Private Act, payable at permit issuance, and even Gallatin, Hendersonville and Goodlettsville require a county certificate that it is paid before they issue. Electrical is generally a state permit, so budget for two authorities on a typical build.
Scope: unincorporated Sumner County through Building and Codes. Gallatin, Hendersonville, Goodlettsville, Portland, White House and others permit their own work — but the county AFT reaches them.
The Adequate Facilities Tax follows the project into the cities. Even a permit issued entirely inside Gallatin or Hendersonville requires a certificate from the county building inspector that the county AFT has been paid, and a city that issues without it becomes liable to the county for the tax. So account for the AFT wherever in Sumner County you build, and confirm the current per-square-foot rate with the AFT coordinator before you bid.
What requires a permit in Sumner County?
Sumner County Building and Codes, at 355 N. Belvedere Drive, Room 208 in Gallatin, is the building authority for unincorporated Sumner County. The cities inside it — Gallatin, Hendersonville, Goodlettsville, Portland, White House, Millersville and Westmoreland — run their own permitting, so a parcel inside a municipality goes to the city rather than the county. The department administers plan review, permitting and inspections and also handles health, safety and property maintenance.
The distinctive feature here is the Adequate Facilities Tax (AFT). Under Chapter 57 of the Private Acts of 1999, Sumner County imposes a per-square-foot privilege tax on new residential, commercial and industrial development, payable at the time the building permit is issued, to help pay for the public facilities that growth requires. It is collected at the county Building and Codes office, and there is a dedicated AFT coordinator. Tennessee does not have one permitting model, it has three, and which one applies decides who your building official actually is. A jurisdiction that has adopted codes meeting the state minimum and enforces them is an exempt jurisdiction: it runs its own plan review, permits and inspections, and the state stays out except for state buildings, schools and a handful of licensed occupancies. A jurisdiction that has not is non-exempt, and the State Fire Marshal's Office is the building official there, working through contracted deputy building inspectors who cover several counties each. And a jurisdiction that has passed a two-thirds resolution under T.C.A. § 68-120-101(b)(1)(B) is an opt-out or non-code jurisdiction, where one- and two-family dwellings sit outside the statewide standards altogether.
What surprises people is that the AFT reaches into the cities. When a building permit is issued by one of Sumner County's incorporated cities, the city must first require a valid certificate from the county building inspector that the full county AFT has been paid — and a city that issues without that certificate becomes liable to the county for the tax. So even a permit pulled entirely inside Gallatin or Hendersonville carries a county step. The county enforces the 2021 editions of the International Codes, adopted by resolution in 2023.
No political subdivision of Tennessee may adopt or enforce standards of fire prevention, fire protection or building construction that are less stringent than the state minimum. Local amendments can add to the code; they cannot subtract from it.

Sumner County building department: who handles permitting
Building and Codes is a multi-role office: it runs plan review, permitting and inspections for the unincorporated county, administers the Adequate Facilities Tax, and handles property maintenance and health-and-safety violations. Addresses are assigned by Sumner County Emergency Services rather than by the codes office, so a new parcel needs its address established before a permit application is complete.
The AFT is the step most likely to catch someone building for the first time in Sumner County. It is a per-square-foot tax under the 1999 Private Act, and because it is assessed at issuance and reaches the cities through the certificate requirement, there is no way to build new square footage in the county — city or unincorporated — without accounting for it. Confirm the current rate with the AFT coordinator before you price a project.
Two other county desks sit alongside the building permit. A driveway or road access permit comes from the Sumner County Highway Department, and on a septic property the TDEC approval has to be in hand first. Neither is issued by Building and Codes, and both take their own time, so line them up early rather than discovering them at the counter.

Account for the AFT before you price the job. The Adequate Facilities Tax is a per-square-foot county tax on new development, collected at permit issuance, and even the cities require a county certificate that it is paid before issuing. Confirm the current rate with the AFT coordinator, and get your address assigned by Emergency Services before you file.
Confirm from the parcel whether the site is unincorporated Sumner County or inside Gallatin, Hendersonville, Goodlettsville or another city, because the permitting office changes at the city line — though the county Adequate Facilities Tax follows the project into the cities through the certificate requirement, so the county is rarely out of the picture entirely.
Sumner County permits: record types and what each covers
Sumner County runs residential and commercial building records, with the Adequate Facilities Tax attaching to new development. These are the records you are likely to file:
Residential permit types
| Permit type | What triggers it | Review path | Fee basis |
|---|---|---|---|
| New construction | New dwellings, additions, and accessory structures above the local size threshold | Plan review against the adopted residential code, plus zoning; the state floor is the 2018 IRC with Appendix Q | Valuation-based |
| Addition | Added interior space, including additions of thirty square feet or more | Structural and energy review; the thirty square foot interior trigger is smaller than most applicants expect | Valuation-based |
| Renovation / alteration | Structural changes, layout changes, or added plumbing, mechanical, or electrical | Plan review scaled to scope; renovations of existing one- and two-family dwellings sit outside the state minimum standards | Valuation-based |
| Reroof | Roof covering replacement, recover, and structural deck repair | Deck and dry-in inspection; plan review rarely required | Valuation or squares |
| Solar photovoltaic | Rooftop or ground-mount arrays, with or without battery storage | Structural review of the attachment locally, with the electrical scope usually permitted and inspected by the state | Flat or system-size based |
| Battery energy storage | Wall or floor-mounted storage added to a dwelling | Electrical review plus fire separation and location check | Flat or per-permit minimum |
| Electrical | Service changes, panel upgrades, new circuits, EV chargers, and rewiring | In most of Tennessee a state record bought through CORE and inspected by a contracted Deputy Electrical Inspector, not a local one | Per-permit or per-device |
| Plumbing | New piping, repipes, fixtures, gas piping, and water heater replacement | Trade review; performed by a licensed plumber or a Limited Licensed Plumber below the contractor threshold | Per-permit minimum or per-fixture |
| Mechanical / HVAC | Changeouts, new ductwork, and refrigeration | Trade review; the contractor licence attaches once the trade portion reaches the statutory threshold | Per-permit minimum or per-unit |
| Deck and porch | New decks, screened porches, and structural rebuilds | Structural review of footings, ledger attachment, and guards | Valuation or flat |
| Swimming pool | In-ground and above-ground pools | Barrier, bonding, and electrical review; the bonding scope generally follows the state electrical record | Valuation or flat |
| Manufactured home set-up | Placing or re-siting a manufactured home | Zoning, floodplain, and anchoring review; manufactured homes sit outside the state minimum building standards but not outside local zoning | Flat or per-unit |
| Demolition | Full or partial demolition of a dwelling or accessory structure | Utility disconnect confirmation and site restoration check | Flat |
| New single-family dwelling | Building a new home in the unincorporated county | Building review against the 2021 codes, with the AFT at issuance | Per-square-foot AFT plus permit fee |
| Addition with new square footage | Adding conditioned floor area to a home | Building review, with the AFT assessed on the new square footage | Per-square-foot AFT plus permit fee |
Commercial permit types
| Permit type | What triggers it | Review path | Fee basis |
|---|---|---|---|
| New commercial construction | Ground-up commercial, industrial, and institutional buildings | Concurrent review against the adopted building code, fire, and zoning; the state floor is the 2021 IBC with Tennessee amendments | Valuation-based |
| Tenant improvement / upfit | Interior fit-out of an existing tenant space | Building, trade, and life-safety review; accessibility attaches on change of use | Valuation-based |
| Change of occupancy | Converting a building or space to a different use group | Occupancy classification, egress, and accessibility review | Valuation or flat |
| Commercial electrical | Service, distribution, and branch circuit work | State record in most jurisdictions unless the municipality is one of the roughly thirty-five authorised to inspect its own electrical | Per-permit or valuation |
| Commercial plumbing | Process piping, fixtures, backflow, and grease waste | Trade review; backflow and grease interceptor sign-off where applicable | Per-fixture or valuation |
| Commercial mechanical | Rooftop units, kitchen exhaust and hood systems, and refrigeration | Trade review; hood and suppression systems draw fire review alongside mechanical | Per-unit or valuation |
| Commercial reroof | Roof covering replacement on a commercial structure | Deck, dry-in, and attachment inspection | Valuation or squares |
| Signage | Wall, ground, and illuminated signs | Zoning review for size and placement, plus electrical where illuminated | Flat or per-sign |
| Land disturbance | Clearing, grading, and stormwater-triggering site work | Erosion and sediment control review, separate from the building permit | Acreage-based |
| Commercial demolition | Full or partial demolition of a commercial structure | Utility disconnect, asbestos notification, and site restoration | Flat or valuation |
| State Fire Marshal plans review | Occupancies requiring State Fire Marshal approval, including schools and certain licensed facilities | Filed with the state through the plans submittal portal, in addition to and not instead of the local record | State fee schedule |
| Commercial new construction | A new commercial building in the county | Full building review, with the AFT on the new square footage | Per-square-foot AFT plus permit fee |
| Industrial development | A new industrial building or expansion | Building review, with the AFT at its industrial per-square-foot rate | Per-square-foot AFT plus permit fee |
Residential
- Single-discipline review in most cases
- The electrical record is usually a separate state permit, not a line on the building permit
- Contractor licence attaches at the statutory threshold; a Home Improvement licence may apply below it in nine counties only
- Septic properties need TDEC approval before ground is broken
Commercial — multi-discipline
- Concurrent review across building, trades, fire, and zoning
- Signed and sealed plans across every affected discipline
- The licensee's monetary limit caps the job value, separately from the permit
- Accessibility and life-safety review attach to any change of occupancy

Solar permits in Sumner County
Solar is reviewed on two tracks at once in Tennessee, and in most of the state those two tracks belong to two different governments. The structural side — attachment detail, rail spacing, and whether the existing framing carries the added dead load — is a local building review. The electrical side — conductors, overcurrent protection, rapid shutdown, labelling, and the service or supply-side connection — usually runs on a state electrical record instead, against the National Electrical Code edition the state programme enforces.
A residential solar installation in unincorporated Sumner County is a county building permit for the structural attachment plus a state electrical permit for the wiring and interconnection, since electrical here is generally a state record through CORE rather than a county one. The local power company sets the meter release and usually waits on an approved electrical inspection, so line up the state electrical permit alongside the county building permit and confirm the interconnection requirements with the power company early. A ground-mounted array on a separate structure can draw its own structural review.
That split is the most common cause of a stalled Tennessee solar job. An installer who files the building record locally and assumes the electrical inspection comes with it will sit waiting for an inspector who was never booked. Confirm at the outset whether your jurisdiction is one of the roughly thirty-five municipalities authorised to run its own electrical inspections, or whether the electrical permit has to be bought from the state.
Interconnection runs on a third clock. Tennessee is served by the Tennessee Valley Authority through local power companies — municipal electric systems and rural electric cooperatives — and each sets its own application, meter and witness-test sequence. Permission to operate is not something the building department controls, so plan for the tracks to finish at different times.
Roofing permits in Sumner County
A roof covering replacement needs a permit in most Tennessee jurisdictions that enforce their own codes. The permit is usually quick, but it is not optional, and the inspection that matters happens before the covering goes on rather than after.
Tennessee has no statewide product-approval database, so there is no approval number to search for or cite on the application. The assembly has to comply with the adopted code and the manufacturer's listed installation instructions, and that pairing is what the inspector checks — which makes the manufacturer's instructions a document worth having on site.
A re-roof in unincorporated Sumner County is a county building permit reviewed against the 2021 codes, covering the structural and weatherproofing requirements for the new covering. A like-for-like replacement is straightforward, while adding load — heavier tile over asphalt, for example — or altering the roof structure draws closer review. Keep the permit and approved scope on site, and provide a ladder for the roof inspection, since the county requires access for a roof-mounted check.
Sequencing is where reroofs go wrong. The deck and dry-in condition has to be visible when the inspector arrives, so covering it first means opening it back up. Where a previous layer has been torn off, expect attention to deck fastening and to any sheathing replaced along the eaves. Note also that a roofing subcontractor is licensed on the value of the roofing portion alone once that portion reaches the statutory threshold.
Sumner County permit cost
Two separate charges drive the cost of building in Sumner County. The building permit fee is set by Building and Codes against the submitted scope, and the Adequate Facilities Tax is a per-square-foot privilege tax under the 1999 Private Act, assessed at issuance. The AFT is the one most likely to be underestimated, because it scales with square footage rather than being a flat fee, and it applies to commercial and industrial as well as residential development.
Because electrical is generally a state permit here, the electrical cost is a state fee through CORE rather than a county line item. Confirm the current building permit fee and AFT rate with the department before budgeting, and remember the AFT reaches a project even when the building permit itself is issued by one of the cities.
| Fee component | How it works |
|---|---|
| Building permit | Set by Building and Codes against the submitted scope |
| Adequate Facilities Tax | Per-square-foot on new residential, commercial and industrial development |
| AFT and the cities | City permits require a county certificate that the AFT is paid |
| Electrical | State permit fee via CORE, not a county line item |
| Driveway | Access permit from the Sumner County Highway Department |
| Septic properties | TDEC approval required before ground is broken |
| Confirm | Current fee and AFT rate with Building and Codes before budgeting |

Sumner County trade permits
Electrical is generally a state permit; plumbing, mechanical and gas follow the normal contractor rules. Four Sumner specifics decide whether your application moves:
The AFT attaches to new square footage
The Adequate Facilities Tax is assessed per square foot on new development at permit issuance, and it reaches city permits through the county certificate requirement. Price it into any new build in Sumner County, city or unincorporated, before you bid.
Electrical is generally the state's
Sumner County is not among the roughly thirty-five Tennessee municipalities authorised to run their own electrical inspections, so the electrical record is usually a state permit through CORE, inspected by a state-contracted Deputy Electrical Inspector. Confirm rather than assuming it comes with the building permit.
The address has to exist first
Addresses are assigned by Sumner County Emergency Services, not the codes office. A new parcel needs its address established before the permit application is complete, so start that step early.
City or county, decided from the parcel
The county permits the unincorporated area; Gallatin, Hendersonville, Goodlettsville and the other cities permit their own work. Confirm the parcel before you file — though the county AFT follows the project either way.
Sumner County permit application: how to apply step by step
Here is how to get a building permit in Sumner County, from confirming the requirement through to close-out. Each step below corresponds to a real decision point where projects commonly stall.
Gallatin, Hendersonville, Goodlettsville and the other cities permit their own work. Settle jurisdiction from the parcel before you start — but note the county Adequate Facilities Tax applies either way.
Addresses are assigned by Sumner County Emergency Services. On a septic property, obtain the TDEC approval before the county can issue. Both are prerequisites, not closing items.
Design to the 2021 International Codes the county adopted in 2023. Prepare plans, a plot plan showing distances from property lines, and any driveway access permit from the Highway Department.
Confirm the current per-square-foot AFT rate with the AFT coordinator and include it in the project cost. It is assessed at permit issuance and scales with square footage.
File with Building and Codes, clear plan review against the 2021 codes, and pay the building permit fee and the AFT. Electrical is a separate state permit through CORE.
Book county building inspections, run the state electrical inspection on its own track, and carry the project through to the certificate of occupancy before legal use.
Inspections in Sumner County
County building inspections are scheduled against the issued permit, with typical checkpoints running footing and foundation, trade rough-ins, framing, insulation and final, reviewed against the 2021 International Codes. During construction the approved construction documents, permit card and inspector signature cards should be available on site, and a ladder must be provided for any roof-mounted inspection.
Electrical inspections run on the state's track through CORE, arranged and regulated by the state rather than the county. On a project that also draws a driveway access permit or a septic authorisation, keep those sequences straight — each has its own authority, and a hold on one is not a hold on another.
The Adequate Facilities Tax is settled at issuance rather than at inspection, so by the time a project reaches its inspections the AFT is behind it — but on a change of occupancy or an addition, confirm what was previously permitted against what is standing, because unpermitted square footage surfaces there and can carry its own AFT question.
Keep the approved documents, permit card and inspector signature cards on site, and provide a ladder for roof-mounted inspections. On an existing building, confirm the permit history against what is standing before a change of occupancy or an addition.

Frequently asked questions
Who issues building permits in Sumner County, TN?
Sumner County Building and Codes, at 355 N. Belvedere Drive, Room 208 in Gallatin, for unincorporated Sumner County. Gallatin, Hendersonville, Goodlettsville, Portland, White House and the other cities run their own permitting. The department line is (615) 452-1467.
What is the Adequate Facilities Tax in Sumner County?
A per-square-foot privilege tax on new residential, commercial and industrial development, imposed under Chapter 57 of the Private Acts of 1999 and payable when the building permit is issued. It helps pay for the public facilities that growth requires, and it is collected at the county Building and Codes office.
Does the Adequate Facilities Tax apply inside the cities?
Yes. When one of Sumner County's incorporated cities issues a building permit, it must first require a valid certificate from the county building inspector that the full county AFT has been paid. A city that issues without that certificate becomes liable to the county for the tax, so even a city permit carries a county AFT step.
Which building code does Sumner County enforce?
The 2021 editions of the International Codes, adopted by county resolution in 2023. As a local building authority under the statewide minimum standards, the county's adopted set governs, so confirm the current editions with the department before you design.
Does Sumner County issue electrical permits?
Generally no. Sumner County is not among the roughly thirty-five Tennessee municipalities authorised to run their own electrical inspections, so the electrical record is usually a state permit through CORE, inspected by a state-contracted Deputy Electrical Inspector.
How do I get an address for a new parcel in Sumner County?
Addresses are assigned by Sumner County Emergency Services, not the codes office. A new parcel needs its address established before the building permit application is complete, so start that step early in the process.
Do I need a contractor licence in Sumner County?
A Tennessee contractor licence is required to bid or perform work valued at twenty-five thousand dollars or more, including labour and materials, and the same threshold reaches trade subcontractors on their own portion.
Do I need a Home Improvement licence in Sumner County?
No. Sumner is not one of the nine Tennessee counties that require the Home Improvement licence. Below the twenty-five thousand dollar contractor threshold there is no separate state home improvement credential here, though local registration and trade licences still apply.
Do I need a septic approval before a building permit in Sumner County?
On a parcel without public sewer, yes. The state's TDEC subsurface sewage disposal program issues the septic permit, and it must be in hand before the county can issue the building permit. The system is sized to bedroom count, so adding bedrooms needs its own approval.
Where does a driveway permit come from in Sumner County?
From the Sumner County Highway Department, separately from the building permit. A driveway or road access permit is its own approval, so account for it when planning site access.
Does Sumner County check my HOA covenants?
No. Deed restrictions, covenants and subdivision regulations are private matters between the owner and the subdivision. A permit that clears the county can still breach a covenant, and the county will not have checked.
What do I need on site during a Sumner County inspection?
The approved construction documents, the permit card and the inspector signature cards should be available on site during construction. For any roof-mounted inspection, you must provide a ladder at the time of inspection.
