Digital permit application gateway
Start with the issuing authority’s own submission lane. A complete application package, accurate valuation, and accessible inspection path are the fastest route through statutory plan review.
Recommended first click
Use the official digital gateway to submit plans, monitor review comments, pay required charges, and request inspections when the permit is issued. If the link is unavailable, use the agency website or phone number on the administrative profile to confirm the current lane.
Typical review lane
N/A; Johnson County publishes no county building-permit review timeline because it does not require county building permits.
Treat this as a planning signal, not a guaranteed approval date. Completeness, corrections, resubmittals, and agency workload control the actual clock.
Verify the parcel is inside this agency’s service area and note whether a city, state, fire marshal, septic authority, or utility district also has approval authority.
Prepare legible plans, site information, project valuation, ownership authorization, contractor information, and any energy, floodplain, zoning, or utility documentation the issuing office requires.
Keep the permit number, approved plan set, correction comments, fee receipts, and inspection results together. Those records establish the compliance trail for the next trade.
Application documents
Before submission, call 423-727-9696 (County Mayor’s Office); 423-727-7692 (Property Assessor); 615-741-7170 (State Fire Marshal residential information) if the project involves a change of occupancy, structural alteration, accessory structure, demolition, or work near a regulated environmental feature.
Source trail
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.
Project questions
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 423-727-9696 (County Mayor’s Office); 423-727-7692 (Property Assessor); 615-741-7170 (State Fire Marshal residential information).
N/A; Johnson County publishes no county building-permit review timeline because it does not require county building permits.
For ordinary county construction, obtain the required septic approval through TDEC and electrical permit/inspection through Mountain Electric. Johnson County also says it issues Certificates of Occupancy despite not requiring building permits. Owners or contractors may optionally obtain a State Fire Marshal permit and request inspections through https://core.tn.gov/; state guidance says inspections may result in a Certificate of Occupancy for one- and two-family dwellings in opt-out/non-code jurisdictions.
Johnson County’s official newcomer information and Assessor letter state that the county does not require building permits or inspections. The county’s public materials do not identify a locally enforced building-code edition. For an optional State Fire Marshal inspection, Tennessee uses the 2018 International Residential Code and 2018 International Energy Conservation Code with amendments. No county building permit is currently required for new structures or additions, and the county says it has no building-permit or zoning department. The county’s stated requirements are a septic permit through TDEC and an electrical permit/inspection through Mountain Electric. State guidance separately exempts detached garages, sheds, barns, and other detached nonliving structures from a state residential permit and generally does not require a state permit for manufactured or modular installation unless custom site work is included.
What makes an application complete
Before you click submit, make sure the drawings agree with the site plan, project description, valuation, ownership authorization, and contractor information. If the work changes structure, occupancy, drainage, fire protection, energy performance, or utility demand, describe that scope plainly. Ambiguous narratives create correction cycles and delay the field schedule.
Save the confirmation number, payment receipt, uploaded plan set, and every correction comment. Those records are the backbone of a defensible compliance file when multiple trades or agencies share responsibility.
Submission quality check
Site: address, parcel, access, setbacks, and existing conditions are consistent.
Scope: structural, mechanical, plumbing, electrical, fire, and energy work is identified.
Closeout: inspection contacts and the final approval path are understood before work begins.
