The Town of Smyrna Building Safety Department is the building authority inside Smyrna — a Rutherford County town north of Murfreesboro. It enforces the town's building, plumbing, mechanical, gas and electrical codes on the 2024 editions with town modifications, so it issues its own electrical, and it runs the Front Street Historic District.
Smyrna issuing its own electrical is the operational difference from unincorporated Rutherford County, which routes it to the state. And because Smyrna sits in Rutherford County, one of nine Home Improvement counties, the Home Improvement licence rule reaches mid-sized residential work in the town.
Scope: inside the town limits of Smyrna through the Building Safety Department. Unincorporated Rutherford County, Murfreesboro and LaVergne permit their own work.
Town electrical, 2024 codes, and the Home Improvement rule. Smyrna's Building Safety Department issues its own building, plumbing, mechanical, gas and electrical permits on the 2024 codes with town modifications. Because Smyrna is in Rutherford County, one of nine Home Improvement counties, confirm the contractor credential, and check the Front Street Historic District.
What requires a permit in Smyrna?
The Town of Smyrna Building Safety Department is the building authority inside the town limits of Smyrna — a fast-growing Rutherford County town north of Murfreesboro, home to a major automotive assembly plant. The department performs plan examinations, issues construction permits, conducts inspections and issues Certificates of Occupancy. It enforces the Town's nationally recognised building, plumbing, mechanical, gas and electrical codes, so unlike an unincorporated county parcel, a Smyrna job keeps electrical in-house rather than routing it to the state.
Smyrna is on the 2024 International Codes with Town of Smyrna modifications, matching Rutherford County's 2024 adoption, so the town is on a current set. The town also runs the Front Street Historic District, where design review applies on top of the building permit for work in the district. 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.
The credential picture carries a Rutherford County wrinkle: Smyrna sits in Rutherford County, one of the nine Tennessee counties where the Home Improvement licence applies, so mid-sized residential improvement work below the full contractor threshold may require that state credential. Confirm which licence a residential job needs before bidding, and confirm zoning and any historic-district review for the parcel. 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.

Smyrna building department: who handles permitting
The Building Safety Department is a full-service town office: plan examinations, permits, inspections and Certificates of Occupancy, across building, plumbing, mechanical, gas and electrical work. The town issuing its own electrical is the operational difference from unincorporated Rutherford County, where electrical routes to the state — a Smyrna job keeps all the trades on the town's track.
The Home Improvement licence rule follows the county, not the town. Rutherford County is one of only nine Tennessee counties where the state Home Improvement licence applies, and because Smyrna sits within Rutherford County, that rule reaches work in the town. For residential improvement work below the full contractor threshold, confirm whether the Home Improvement licence is the right credential before bidding.
The Front Street Historic District adds a design-review layer. Work on a property in the district is reviewed for its effect on the historic character in addition to the building permit, so a project in that area should account for the review in its schedule. The town's construction, planning and zoning material sets out the district and the design standards that apply.

Town electrical, 2024 codes, and the Home Improvement rule. Smyrna's Building Safety Department issues its own building, plumbing, mechanical, gas and electrical permits on the 2024 codes with town modifications. Because Smyrna is in Rutherford County, one of nine Home Improvement counties, confirm the contractor credential, and check the Front Street Historic District.
Confirm from the parcel whether the site is inside the town limits of Smyrna or in unincorporated Rutherford County, Murfreesboro or LaVergne, because the permitting office changes at the town line — and Smyrna issues its own electrical while the unincorporated county routes it to the state.
Smyrna permits: record types and what each covers
Smyrna runs residential and commercial building records and its own trade permits. 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 inside the town | Building review against the 2024 codes; town trade permits | Fee by scope |
| Home improvement work | Mid-sized residential improvement work | Reviewed; the Home Improvement licence may apply in Rutherford County | Fee by scope |
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 or industrial building | Full plan review; town trade permits | Fee by scope |
| Historic district work | Work in the Front Street Historic District | Design review in addition to the building permit | Fee by scope |
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

| Commercial building permit | Commercial and industrial construction |
| Town electrical permit | Issued by the town under its electrical code |
| Plumbing permit | New piping, repipes, and fixtures |
| Mechanical / gas permit | HVAC changeouts, ductwork, and gas work |

| Sign permit | Under the town sign ordinance |
| Demolition permit | Full or partial demolition |
Solar permits in Smyrna
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 inside Smyrna is a town building permit for the structural attachment plus a town electrical permit for the wiring, because the Building Safety Department issues its own electrical rather than routing it to the state. That keeps the solar job on the town's track — different from unincorporated Rutherford County, where electrical is a state permit. The local power company sets the meter release on an approved electrical inspection, so confirm the interconnection path early.
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 Smyrna
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 inside Smyrna is a town building permit reviewed against the 2024 codes with town modifications. A like-for-like replacement is straightforward; adding load or altering the roof structure draws closer review. Because Rutherford County is a Home Improvement county, confirm whether a mid-sized roofing job needs the Home Improvement licence or the full contractor licence, and check the Front Street Historic District.
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.
Smyrna permit cost
Smyrna building permit fees are set by the Building Safety Department against the project, with the town issuing its own electrical, plumbing, mechanical and gas permits rather than routing electrical to the state. Work in the Front Street Historic District carries the added step of design review.
Confirm the current fee basis with the department before budgeting, and confirm whether a mid-sized residential job requires the Home Improvement licence or the full contractor licence, since Rutherford County is a Home Improvement county.
| Fee component | How it works |
|---|---|
| Building permit | Set by the Building Safety Department against the project |
| Trade permits | Town electrical, plumbing, mechanical and gas fees |
| Historic district | Design review for work in the Front Street district |
| Credential | Home Improvement or full contractor licence, confirmed for the work |
| Certificate of occupancy | Issued by the department after final inspection |
| Septic properties | TDEC approval where there is no public sewer |
| Confirm | Fee basis with the department before budgeting |

Smyrna trade permits
Smyrna issues its own trades, and the Home Improvement rule applies. Four Smyrna specifics decide whether your application moves:
Electrical is the town's
The Building Safety Department enforces the town's electrical code and issues its own electrical permits, alongside plumbing, mechanical and gas. A Smyrna job keeps all the trades on the town's track rather than routing electrical to the state.
The Home Improvement licence applies in Rutherford County
Smyrna sits in Rutherford County, one of nine Tennessee counties where the state Home Improvement licence applies, for residential improvement work below the full contractor threshold. Confirm which credential a mid-sized residential job requires before you bid.
Check the Front Street Historic District
Work on a property in the Front Street Historic District is reviewed for its effect on the historic character in addition to the building permit. Account for the design review in the schedule for a project in that area.
Design to the 2024 codes with town modifications
Smyrna is on the 2024 International Codes with Town of Smyrna modifications, so design to that set and confirm the town's specific amendments. It matches Rutherford County's 2024 adoption.
Smyrna permit application: how to apply step by step
Here is how to get a building permit in Smyrna, from confirming the requirement through to close-out. Each step below corresponds to a real decision point where projects commonly stall.
Unincorporated Rutherford County, Murfreesboro and LaVergne permit their own work. Settle jurisdiction from the parcel, noting Smyrna issues its own electrical while the county routes it to the state.
Because Rutherford County is a Home Improvement county, confirm whether a mid-sized residential job requires the Home Improvement licence or the full state contractor licence before bidding.
Design to the 2024 International Codes with Town of Smyrna modifications, and check whether the parcel is in the Front Street Historic District, which adds design review.
Assemble plans and the site plan, confirm zoning compliance, and on a parcel without public sewer obtain the TDEC septic approval.
Apply with the Building Safety Department for the building permit and the town electrical, plumbing, mechanical and gas permits, and clear any historic-district review.
Book town inspections, run the trade inspections on the town's track, and carry the project through to the town's Certificate of Occupancy before legal use.
Inspections in Smyrna
Town inspections are scheduled against the issued permit and reviewed against the 2024 codes with town modifications, with typical checkpoints running footing and foundation, framing, trade rough-ins, insulation and final. Because the town issues its own electrical, plumbing, mechanical and gas permits, all the trade inspections run on the town's track.
The department issues the Certificate of Occupancy after the final inspections, signifying the structure has been inspected for compliance with all adopted codes. On a Front Street Historic District project, the design-review approval is part of clearing the project.
On an existing building, confirm what was previously permitted against what is standing before a change of occupancy, using the town record. A residential job in the Home Improvement range should have the credential settled before the trades begin.
All trade inspections run on the town's track, since Smyrna issues its own electrical, plumbing, mechanical and gas permits. The department issues the Certificate of Occupancy after the finals — clear any historic-district review as well.

Frequently asked questions
Who issues building permits in Smyrna, TN?
The Town of Smyrna Building Safety Department, for work inside the town limits. It performs plan examinations, issues permits and Certificates of Occupancy, and inspects. Unincorporated Rutherford County, Murfreesboro and LaVergne run their own permitting.
Does Smyrna issue its own electrical permits?
Yes. The Building Safety Department enforces the town's building, plumbing, mechanical, gas and electrical codes, so the town issues its own electrical permits. That differs from unincorporated Rutherford County, where electrical routes to the state.
Which building code does Smyrna enforce?
The 2024 International Codes with Town of Smyrna modifications, matching Rutherford County's 2024 adoption. Confirm the town's specific amendments with the Building Safety Department before you design.
Do I need a Home Improvement licence in Smyrna?
Possibly. Smyrna is in Rutherford County, one of nine Tennessee counties where the state Home Improvement licence applies, for residential improvement work below the twenty-five thousand dollar contractor threshold. Above that threshold a full state contractor licence is required, so confirm which credential your job needs.
Is my Smyrna project in the Front Street Historic District?
It depends on the parcel. Work in the Front Street Historic District is reviewed for its effect on the historic character in addition to the building permit. Check the district boundaries and design standards with the town before starting a project in that area.
Do I need a contractor licence in Smyrna?
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. Below it, the Home Improvement licence may apply here.
How does Smyrna relate to Rutherford County for permits?
Smyrna runs its own Building Safety Department inside the town limits, while unincorporated Rutherford County is permitted by the county Building Codes Department. Both are on the 2024 codes, but Smyrna issues its own electrical while the county routes it to the state.
Does Smyrna issue Certificates of Occupancy?
Yes. The Building Safety Department issues Certificates of Occupancy after the final inspections, signifying the structure has been inspected for compliance with all adopted codes. A certificate is required before legal use.
Do I need a septic approval before a building permit in Smyrna?
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 town can issue the building permit. Much of Smyrna is on public sewer.
Does Smyrna 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 town can still breach a covenant, and the town will not have checked.
What trades does Smyrna permit itself?
Building, plumbing, mechanical, gas and electrical — all issued by the Building Safety Department. That keeps a Smyrna project's trades on the town's track, unlike an unincorporated county parcel where electrical is a state permit.
Is my project in Smyrna or unincorporated Rutherford County?
It depends on the parcel. The town of Smyrna and unincorporated Rutherford County permit their own work. Confirm the parcel is inside the town limits before filing with the Building Safety Department, since the electrical routing and office change at the town line.
