The City of Spring Hill Building Department, at City Hall on Northfield Lane, is the building authority inside Spring Hill — one of Tennessee's fastest-growing cities, about 30 miles south of Nashville. The city spans Williamson and Maury counties, and inside the limits the department is the single authority regardless of county.
The two-county structure has a financial edge: the Adequate Facilities Tax depends on which county the parcel is in — the Maury County tax on the Maury side — on top of the city's own facility tax, charged per gross square foot. The department also validates NFIP and FEMA conformance and enforces the Unified Development Code.
Scope: inside the Spring Hill city limits through the Building Department, across two counties. Unincorporated Williamson and Maury counties permit their own work.
One city, two counties, and a county-dependent facilities tax. Inside the city limits the Building Department permits the work regardless of county, but the Adequate Facilities Tax depends on the parcel's county — the Maury County tax on the Maury side — on top of the city's own per-square-foot facility tax.

What requires a permit in Spring Hill?
The City of Spring Hill Building Department, at City Hall on Northfield Lane, is the building authority inside the city limits of Spring Hill — one of Tennessee's fastest-growing cities, about 30 miles south of Nashville and home to a major automotive assembly plant. Spring Hill is unusual in that it spans two counties, Williamson to the north and Maury to the south, and inside the city limits the Building Department is the single authority regardless of which county the parcel sits in.
The department issues permits and inspects all building activity, validates conformance with the National Flood Insurance Program and FEMA regulations, and enforces the city's Unified Development Code. Commercial plans are submitted by email with a completed application and a digital set including the mechanical, electrical and plumbing drawings. Confirm the current adopted code editions with the department before designing. An exempt jurisdiction cannot let its code go stale indefinitely. Under T.C.A. § 68-120-101(b)(5)(A) the adopted edition must stay within seven years of the most current published edition unless the State Fire Marshal approves otherwise. That seven-year band, rather than a single statewide changeover date, is why two Tennessee cities an hour apart can be on different code years and both be compliant.
The two-county structure has a real financial consequence: the Adequate Facilities Tax that applies depends on which county the parcel is in — a Maury-County-side parcel is subject to the Maury County Adequate Facilities Tax — and that is on top of the City of Spring Hill's own facility tax, which is charged per gross square foot for residential and commercial work under the city's 2022 ordinance. So the same city permit can carry different county-level charges depending on the parcel. 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. 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.

Spring Hill building department: who handles permitting
Spanning two counties, Spring Hill is a single city building authority: inside the city limits the Building Department issues the permit and inspects regardless of whether the parcel is in Williamson or Maury County. Just outside the city, the relevant unincorporated county governs. That makes Spring Hill a teaching case in the same family as Johnson City, which spans three counties, and Kingsport, which spans two — the city line, not the county line, decides who permits.
The county line does matter for money. The Adequate Facilities Tax on new development depends on which county the parcel is in, so a parcel on the Maury County side is subject to the Maury County Adequate Facilities Tax, while the city also levies its own facility tax charged per gross square foot for residential and commercial work under its 2022 ordinance. A new Spring Hill project should therefore price both the city facility tax and the applicable county facilities tax for the parcel.
The city's development framework rounds out the picture. The Building Department validates conformance with the National Flood Insurance Program and FEMA regulations, and the city's Unified Development Code governs land use, site plans, signs and setbacks. Commercial plans go in by email with a completed application and a full digital set, so assemble the mechanical, electrical and plumbing drawings before submitting.

One city, two counties, and a county-dependent facilities tax. Inside the city limits the Building Department permits the work regardless of county, but the Adequate Facilities Tax depends on the parcel's county — the Maury County tax on the Maury side — on top of the city's own per-square-foot facility tax. Confirm the code editions with the department.
Confirm from the parcel whether the site is inside the Spring Hill city limits or in unincorporated Williamson or Maury County, and on which county's side of the city it sits, because the permitting authority is the city inside the limits while the applicable county facilities tax follows the county line.
Spring Hill permits: record types and what each covers
Spring Hill runs residential and commercial building records across two counties. 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 city | Building review; city facility tax plus the county's; per the parcel's county | Fee by scope plus facility taxes |
| Floodplain development | Work on a low-lying or flood-zone parcel | NFIP/FEMA conformance in addition to the building permit | 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 building inside the city | Full plan review by email with a digital MEP set | Fee by scope plus facility taxes |
| Retaining wall or pool | A retaining wall or swimming pool | Building review with structural and barrier checks | 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

Solar permits in Spring Hill
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 Spring Hill is a city building permit for the structural attachment plus an electrical permit for the wiring, handled through the city's Building Department. A roof-mounted retrofit on an existing home is not new development, so the facilities taxes that attach to new construction generally do not apply to it. 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 Spring Hill
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 Spring Hill is a city building permit reviewed against the city's adopted codes. A like-for-like replacement is straightforward; adding load or altering the roof structure draws closer review. A re-roof on an existing home is not new development, so the city and county facilities taxes that attach to new construction do not apply to it.
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.
Spring Hill permit cost
Spring Hill building permit fees are set by the Building Department against the project, but the larger budget items on new development are the taxes: the City of Spring Hill's own facility tax, charged per gross square foot for residential and commercial work, and the county Adequate Facilities Tax, whose form depends on which county the parcel is in.
Confirm the current fee and tax basis with the department before budgeting, and account for the TDEC septic approval on a parcel without public sewer and any floodplain conformance on a low-lying parcel.
| Fee component | How it works |
|---|---|
| Building permit | Set by the Building Department against the project |
| City facility tax | Per gross square foot, residential and commercial |
| County facilities tax | Depends on the parcel's county (Maury AFT on the Maury side) |
| Floodplain | NFIP/FEMA conformance on a low-lying parcel |
| Commercial plans | Application plus a digital MEP set by email |
| Septic properties | TDEC approval where there is no public sewer |
| Confirm | Current fee and tax basis with the department before budgeting |

Spring Hill trade permits
One city authority, two counties, county-dependent tax. Four Spring Hill specifics decide whether your application moves:
Know which county the parcel is in
Spring Hill spans Williamson and Maury counties, and the Adequate Facilities Tax depends on which county the parcel is in — the Maury County tax on the Maury side. Determine the county side of the parcel to price the applicable tax.
Budget the city facility tax too
On top of any county facilities tax, the City of Spring Hill levies its own facility tax per gross square foot for residential and commercial work under its 2022 ordinance. Price both into a new project.
Submit commercial plans by email with the MEP set
Commercial plans are submitted by email with a completed application and a full digital set including the mechanical, electrical and plumbing drawings. Assemble a complete set before submitting.
Validate floodplain and the UDC
The Building Department validates NFIP and FEMA conformance, and the city's Unified Development Code governs land use, site plans and signs. Identify floodplain and UDC requirements early on the parcel.
Spring Hill permit application: how to apply step by step
Here is how to get a building permit in Spring Hill, from confirming the requirement through to close-out. Each step below corresponds to a real decision point where projects commonly stall.
Unincorporated Williamson and Maury counties permit their own work. Inside the city limits, the Building Department is the authority regardless of county, so determine the parcel's county side as well.
Confirm the current adopted code editions with the Building Department before you design, since the city adopts its own set.
Determine the applicable county Adequate Facilities Tax for the parcel's county side, and the city's own per-square-foot facility tax, and price both into the project.
Prepare the plans — commercial by email with a full digital MEP set — validate NFIP/FEMA conformance on a low-lying parcel, and on a septic parcel obtain the TDEC approval.
Apply with the Building Department for the building permit and the electrical, plumbing and mechanical permits, and clear the Unified Development Code review where it applies.
Book city inspections, run the trade inspections, and carry the project through to occupancy before legal use.
Inspections in Spring Hill
City inspections are scheduled against the issued permit and reviewed against the city's adopted codes, with typical checkpoints running footing and foundation, framing, trade rough-ins, insulation and final. The inspections run the same way regardless of which county the parcel is in, since the city is the single authority inside its limits.
On new development, the facilities taxes are settled as part of the permitting rather than at inspection, but confirm the city facility tax and the applicable county Adequate Facilities Tax are accounted for. On a low-lying parcel, the floodplain conformance is checked against the NFIP and FEMA requirements.
On an existing building, confirm what was previously permitted against what is standing before a change of occupancy, using the city record. A project on the city edge should confirm it is inside the city limits rather than in the adjacent unincorporated county.
Inspections run the same regardless of county, since the city is the single authority inside its limits. Confirm the city facility tax and the applicable county facilities tax are settled, and clear all finals before a certificate of occupancy.

Frequently asked questions
Who issues building permits in Spring Hill, TN?
The City of Spring Hill Building Department, at City Hall on Northfield Lane, for work inside the city limits. Because the city spans Williamson and Maury counties, the Building Department is the single authority inside the city limits regardless of which county the parcel sits in.
Which counties does Spring Hill span?
Two — Williamson to the north and Maury to the south. Inside the city limits, the county line does not change who permits the work; it is always the City of Spring Hill Building Department. Just outside the city, the relevant unincorporated county governs.
Does the county facilities tax apply to a Spring Hill permit?
It can, and which one depends on the parcel. The Adequate Facilities Tax on new development depends on which county the parcel is in, so a Maury-County-side parcel is subject to the Maury County Adequate Facilities Tax. That is on top of the city's own facility tax.
What is the City of Spring Hill facility tax?
The city levies its own facility tax charged per gross square foot for residential and commercial work under its 2022 ordinance, separate from any county Adequate Facilities Tax. Confirm the current per-square-foot rates with the Building Department.
Which building code does Spring Hill enforce?
The city adopts and enforces its own building and life-safety codes, so confirm the current adopted editions with the Building Department before you design. The city also validates NFIP and FEMA conformance and enforces its Unified Development Code.
How do I submit commercial plans in Spring Hill?
Commercial plans are submitted by email with a completed application and a digital set including the mechanical, electrical and plumbing drawings. Assemble a complete set before submitting to avoid a delayed review.
Do I need a contractor licence in Spring Hill?
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 Spring Hill?
No. Spring Hill spans Williamson and Maury counties, neither of which is 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.
Do I need a septic approval before a building permit in Spring Hill?
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 city can issue the building permit. Much of the city is on public sewer.
Does Spring Hill validate floodplain conformance?
Yes. The Building Department validates conformance with the National Flood Insurance Program and FEMA regulations, so a low-lying or flood-zone parcel carries floodplain review in addition to the building permit. Check the flood map for the parcel early.
Does Spring Hill 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 city can still breach a covenant, and the city will not have checked.
Is my project in Spring Hill or unincorporated county?
It depends on the parcel. Inside the city limits, the Building Department permits the work regardless of county; just outside, the unincorporated county governs. Confirm the parcel is inside the city limits, and note which county side it sits on for the facilities tax.
