Fees, valuation & enforcement
Permit fees are a project input. Enforcement exposure is a project risk. Use the official schedule where available, then confirm valuation, trade permits, plan review, and inspection charges with the Authority Having Jurisdiction.
Official fee pathway
The final charge may depend on declared construction value, occupancy classification, square footage, plan review, state surcharges, trade permits, technology fees, and inspection activity. Do not use a neighboring city’s fee table as a substitute for this jurisdiction.

Ask the counter to confirm current charges before submitting a project with multiple trades or a change of use.
Financial exposure
Plan for building, mechanical, plumbing, electrical, fire, energy, zoning, septic, right-of-way, or other reviews that the project scope triggers. The lowest initial permit fee is not always the lowest project cost.
Enforcement exposure
When work begins without authorization, the agency may halt the site, require corrective plans, impose additional fees, withhold inspection release, or require concealed work to be exposed for review.
Closeout exposure
A missing final inspection or certificate can complicate occupancy, refinancing, sale, insurance, and utility connection. Preserve the approved plans and signed inspection record through closeout.
Professional field note
Even when a cosmetic or minor project does not require a building permit, zoning, floodplain, shoreline, historic, utility, fire, or right-of-way controls may still apply. Confirm the full jurisdictional picture before work starts.

Use these direct agency or licensing links to confirm current instructions before you file, pay, or schedule work. External pages control if their information differs from this directory.

This record is marked State Fallback. Confirm whether a city, state agency, or other local authority controls the parcel before filing.
Begin with the online permit gateway listed in the application guide. If the portal does not recognize the address or project type, contact 931-296-7795 (Humphreys County Government); 615-741-7170 (State Fire Marshal residential/electrical section); 931-201-3844 (state-listed inspector Ronnie Galloway).
N/A; Humphreys County and the State Fire Marshal’s public materials do not publish a county-specific review timeline. County subdivision regulations provide a 60-day planning-commission period for final subdivision-plat decisions, which is separate from building permits.
For the optional State Fire Marshal path, purchase/service a permit and request inspections through https://core.tn.gov/ or email SFMO.permits-licensing@tn.gov with the full permit number and ready date. State inspections generally cover foundation before pouring, framing/rough-in, and final construction, with plumbing/mechanical checks at rough-in and final. Ronnie Galloway is the state-listed Humphreys County inspector at 931-201-3844. For Waverly projects, the official city FAQ directs inspection requests to Building and Codes at 931-296-2101 ext. 359.
Tennessee’s official Residential Jurisdictions list identifies Humphreys County as OPT OUT of statewide residential building-code enforcement. The optional state inspection path uses Tennessee’s 2018 International Residential Code and 2018 International Energy Conservation Code with amendments. The county publishes subdivision regulations, but no separate county building-code edition. The state list identifies Waverly and McEwen as EXEMPT and New Johnsonville as OPT OUT, so municipal requirements differ inside those cities. Because Humphreys County is OPT OUT, the county does not require a state residential building permit for ordinary unincorporated residential construction under the state program; homeowners may still request state inspection through CORE. State guidance says detached garages, sheds, barns, and other detached non-living structures do not require a state residential permit, while additions over 30 square feet generally do where the state program applies. Manufactured or modular installation itself generally does not require a state residential permit, but custom site work may. Municipal exemptions and permits vary by Waverly, McEwen, and New Johnsonville.
Why permit costs vary
Building departments commonly calculate charges from valuation, occupancy, floor area, project type, plan review effort, trade scope, state surcharges, and inspection activity. A remodel that appears small on paper may still trigger structural, energy, fire, or utility review. Ask the permit counter which disciplines apply before you finalize the construction budget.
The same discipline applies to enforcement. Correcting unpermitted work after finishes are installed can require demolition, revised plans, additional inspections, and schedule disruption. Authorization is usually the less expensive project-management decision.
