Building permits inside the City of Clarksville are issued by the City's Building and Codes department — separate from Montgomery County — across three divisions, on the 2018 International Codes with the 2017 National Electric Code, with a CONO contractor registration required before you apply.
This Clarksville building permit guide covers what requires a permit, the City's Building and Codes department with its Administrative, Construction and Codes Enforcement divisions, the 2018 codes with the 2017 National Electric Code, the CONO contractor registration the city requires, and the certificate of occupancy that closes a project out.
Scope: inside the City of Clarksville limits. Montgomery County permits the area outside the city; the city is most of the county's population.
City and county are separate departments here. Clarksville Building and Codes permits work inside the city limits; Montgomery County Building and Codes permits the area outside. Because Clarksville is the large majority of the county's population, most permits are city permits — but the two departments do not share an application queue, so confirm the parcel first.
What requires a permit in Clarksville?
Building permits inside the City of Clarksville are issued by the City's Building and Codes department, which is separate from Montgomery County Building and Codes. Clarksville is the large majority of Montgomery County's population, so most permits in the county area are actually city permits — but the city and the county are two distinct departments, and a parcel just outside the city limits goes to the county instead. Settle which one owns your parcel first.
Clarksville Building and Codes runs three divisions: the Administrative Division oversees incoming permits and inspection requests and answers customer questions; the Construction Division issues building permits and carries a project through to the certificate of occupancy; and the Codes Enforcement Division handles codes and ordinances dealing with environmental issues. 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 city enforces a full 2018 code set adopted by the City of Clarksville Building and Codes Department — the 2018 IBC (with appendices C, D and F), the 2018 IRC for one- and two-family dwellings (with appendix G), the 2018 energy, fire, fuel gas, mechanical, plumbing and existing-building codes, the 2009 A117.1 accessibility standard, and the 2017 National Electric Code — together with the city's own property maintenance code. The city notes it is the contractor's and design professional's responsibility to check for changes in the applicable code.
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.

Clarksville building department: who handles permitting
The three-division structure is the practical map of a Clarksville project. The Administrative Division is the front door — it takes incoming permits and inspection requests, fields questions in person and by phone, facilitates board meetings and tracks the monthly statistics. The Construction Division is where the building permit is issued and where the project is carried through to the certificate of occupancy. Knowing which division owns which step saves a misdirected call.
Contractor registration runs on a CONO (contractor number) system. A contractor registers with the city and is issued a CONO ID; when a licence or certification lapses, the city specifically asks that you not file a fresh registration but instead email updated documentation and the existing CONO ID to the Building and Codes administrative address. That keeps the registration record continuous rather than creating duplicates.
Because Clarksville and Montgomery County run separate Building and Codes departments and the city is the majority of the population, the most common early error is the city-or-county mix-up. The city permits work inside the corporate limits; the county permits the area outside. Confirm the parcel's status before filing, because the two departments do not share an application queue.
| Detail | Information |
|---|---|
| Authority | City of Clarksville Building and Codes |
| Covers | Inside the City of Clarksville limits only |
| County runs its own | Montgomery County Building and Codes (area outside the city) |
| Divisions | Administrative, Construction, and Codes Enforcement |
| Codes enforced | 2018 International Codes with the 2017 NEC |
| Accessibility | 2009 ICC/ANSI A117.1 |
| Contractor registration | CONO number; email updates rather than re-registering |
| Close-out | Certificate of occupancy from the Construction Division |
| Registration email | bcadmin@clarksvilletn.gov |
CONO first, and confirm city versus county. Clarksville issues contractors a CONO registration number, and asks that you email updated documentation with the existing CONO ID rather than re-registering when a licence lapses. Because the city is most of Montgomery County's population, confirm the parcel is inside the city limits rather than the county's area before you file.
Clarksville and Montgomery County run separate Building and Codes departments, and the city is the large majority of the county's population. Confirm from the parcel whether the site is inside or outside the city limits before you file — the two departments do not share an application queue, and a misdirected application is the most common delay here.
Clarksville permits: record types and what each covers
Clarksville Building and Codes runs residential and commercial records across its three divisions. 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 |
| City electrical permit | Residential wiring, service, or solar | Under the city's 2017 NEC adoption; a city permit, not a state one | Valuation-based |
| Manufactured home placement | Setting a manufactured home in the city | Placement with a set-up inspection through the Construction Division | Valuation-based |
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 building permit | Commercial construction or tenant work | Requires drawings sealed by a Tennessee-registered architect or engineer | Valuation-based |
| Certificate of occupancy | Occupying completed commercial space | Issued by the Construction Division once all inspections are approved | Flat |
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
Records you will actually see in Clarksville
| Record | What it covers |
|---|---|
| Residential building permit | New homes, additions, alterations, and repairs |
| Commercial building permit | Commercial construction and tenant work |
| Accessory structure | Above the city threshold |
| Swimming pool | With barrier and bonding review |
| Electrical permit | Under the city's 2017 NEC adoption |
| Plumbing / mechanical / gas | Trade permits under the city's adopted codes |
| Demolition permit | Full or partial demolition |
| Manufactured home | Placement with set-up inspection |
Solar permits in Clarksville
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 the City of Clarksville is a building permit for the structural attachment plus an electrical permit — and the electrical here is a city permit under Clarksville's own 2017 NEC adoption, rather than a state record as in most of Tennessee. That keeps the solar job within the city's Building and Codes department. The contractor needs a current CONO registration, and if a licence has lapsed the city asks for emailed updates against the existing CONO ID rather than a fresh registration.
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 Clarksville
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.
Reroofing requires a permit inside the City of Clarksville and is filed with Building and Codes. The work is reviewed against the city's 2018 codes, and a residential reroof is charged against the value of the improvements. The city notes it is the contractor's and design professional's responsibility to check for code and fee changes, since the fee schedule is amended by ordinance. On a tear-off that exposes the deck, the inspection looks at the sheathing and structure.
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.
Clarksville permit cost
Clarksville building permit fees are set by the city's Building and Codes department, assessed against the submitted scope, and amended from time to time through the city code — the building permit fee provisions sit in Title 4 of the city code and have been updated by ordinance. Because the city adopts its own electrical code, the electrical permit here is a city permit rather than a state one.
Confirm current amounts against the department before budgeting. The city's own note — that it is the contractor's and design professional's responsibility to check for changes in the applicable code and fee — is worth taking literally, because the fee schedule is amended by ordinance rather than fixed.
| Fee component | How it works |
|---|---|
| Basis | Building permit fees set by the city's Building and Codes department |
| Fee authority | Title 4 of the city code, amended by ordinance |
| Electrical | A city permit under the 2017 NEC, not a state permit |
| Registration | CONO contractor registration required before applying |
| Close-out | Certificate of occupancy from the Construction Division |
| Septic properties | State approval where there is no public sewer |
| Confirm | Against the Building and Codes department before budgeting |

Clarksville trade permits
Trade permits run under the city's own adopted codes, including its 2017 NEC. Four Clarksville specifics decide whether your application moves:
Register with a CONO number first
Clarksville issues contractors a CONO registration number, required before applying. When a licence or certification lapses, email updated documentation and the existing CONO ID to bcadmin@clarksvilletn.gov rather than filing a fresh registration.
Electrical is a city permit here
Clarksville adopts the 2017 National Electric Code and issues electrical permits itself, rather than routing them to the state as most of Tennessee does. The electrical permit is a city record under the city's own adoption.
Know which division you need
The Administrative Division takes permits and inspection requests and answers questions; the Construction Division issues building permits and carries the job to the certificate of occupancy; Codes Enforcement handles environmental ordinances. The right division speeds the call.
City limits only
Building and Codes permits work inside the city. Montgomery County permits the area outside, and the city is the majority of the county's population. Confirm the parcel is city before you file.
Clarksville permit application: how to apply step by step
Here is how to get a building permit in Clarksville, from confirming the requirement through to close-out. Each step below corresponds to a real decision point where projects commonly stall.
Clarksville permits work inside the corporate limits; Montgomery County permits the area outside. Because the city is most of the county's population, confirm the parcel's status from the parcel before you start.
Register with the city's Building and Codes department for a CONO number before applying. If a licence or certification has lapsed, email updated documentation with the existing CONO ID rather than re-registering.
Design to the city's 2018 International Codes with the 2017 National Electric Code and the 2009 A117.1 accessibility standard. Check for any code or fee changes, which the city notes are the applicant's responsibility to track.
Prepare plans, site plan and, for commercial work, sealed drawings. File with the Administrative Division, which takes incoming permits and inspection requests.
The Construction Division issues the building permit once review is cleared. Electrical is a city permit under the 2017 NEC. Confirm the current fee, which is amended by ordinance, before paying.
Book inspections through the Administrative Division, run through to final, and obtain the certificate of occupancy from the Construction Division before legal occupancy or use.
Inspections in Clarksville
Inspection requests run through the Administrative Division against the issued permit, with the Construction Division carrying a project from permit issuance to the certificate of occupancy. Typical checkpoints run footing and foundation, trade rough-ins, framing, insulation and final, reviewed against the city's 2018 codes and 2017 NEC, with the permit and approved plans on site.
Because Clarksville adopts its own electrical code, the electrical inspection here is the city's rather than a state track. That keeps the trade inspections under the city's Building and Codes department, which is simpler than the state-electrical split that applies across most of Tennessee — provided the electrical permit was pulled as a city permit in the first place.
The certificate of occupancy from the Construction Division is the close-out instrument. On an existing Clarksville building, the department's records are the way to confirm what was previously permitted before a change of occupancy, which is where unpermitted work tends to surface. Match the record against what is standing before you take a building on.
The Administrative Division takes inspection requests; the Construction Division issues the certificate of occupancy. On an existing building, confirm the permit history against what is standing before a change of occupancy, because unpermitted work surfaces at that point.

Frequently asked questions
Who issues building permits in Clarksville, TN?
The City of Clarksville's Building and Codes department, for work inside the city limits. It is separate from Montgomery County Building and Codes, which permits the area outside the city. Because Clarksville is most of the county's population, confirm the parcel is city before you file.
Which building code does Clarksville enforce?
A full 2018 International Code set adopted by the city — the 2018 IBC, IRC, energy, fire, fuel gas, mechanical, plumbing and existing-building codes, plus the 2009 A117.1 accessibility standard and the 2017 National Electric Code — together with the city's own property maintenance code.
How do I apply for a Clarksville building permit?
Register with the city's Building and Codes department for a CONO contractor number first, then file with the Administrative Division, which takes incoming permits and inspection requests. The Construction Division issues the building permit and carries the project to the certificate of occupancy.
What is a CONO number in Clarksville?
It is the city's contractor registration number. A contractor registers with Building and Codes and is issued a CONO ID. When a licence or certification lapses, the city asks that you email updated documentation and the existing CONO ID to bcadmin@clarksvilletn.gov rather than filing a fresh registration.
Does Clarksville or the county issue my permit?
Clarksville issues permits inside the city limits; Montgomery County issues permits for the area outside the city. Because the city is the large majority of the county's population, most permits are city permits, but a parcel just outside the limits goes to the county.
Does Clarksville issue its own electrical permits?
Yes. Clarksville adopts the 2017 National Electric Code and issues electrical permits itself under that adoption, rather than routing them to the state as most of Tennessee does. The electrical permit is a city record here.
What are the three Building and Codes divisions?
The Administrative Division oversees incoming permits and inspection requests and answers questions; the Construction Division issues building permits and carries a project to the certificate of occupancy; and the Codes Enforcement Division handles codes and ordinances dealing with environmental issues.
Do I need a contractor licence in Clarksville?
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. The city additionally requires a CONO registration before applying.
Do I need a Home Improvement licence in Clarksville?
No. Montgomery County, which contains Clarksville, 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.
Who issues the certificate of occupancy in Clarksville?
The Construction Division, which carries a project from permit issuance through to the certificate of occupancy once all inspections are approved. The certificate is required before legal occupancy or use of the completed building.
Does Clarksville 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.
How do I confirm what was permitted on a Clarksville property?
The Building and Codes department's records are the way to confirm what was previously permitted on an existing building. Match that record against what is standing before filing a change of occupancy, because unpermitted work surfaces at that point.
