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
Allow approximately three days for requested inspections; the county does not publish a separate plan-review timeline.
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 423-323-6440 (Planning and Codes); 423-323-6440 also listed for permit questions; 423-279-2820 (County Highway driveway permits) 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
Sullivan County Department of Planning and Codes is the identified county-level authority for this profile. Confirm that the property is in its service area 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 423-323-6440 (Planning and Codes); 423-323-6440 also listed for permit questions; 423-279-2820 (County Highway driveway permits).
Allow approximately three days for requested inspections; the county does not publish a separate plan-review timeline.
The applicant is responsible for calling for required inspections and for requesting the final inspection and Certificate of Occupancy. The official application says to allow a three-day turnaround for inspections, which are handled in the order received. New residential applications require a plot plan; nonresidential applications require a site plan, and new buildings require water/sewer or septic documentation and a floodplain elevation certificate when applicable.
Sullivan County states that the Board of County Commissioners adopted the 2018 International Residential Code and the 2018 Energy Code, effective April 1, 2018. County materials also identify the current zoning resolution, stormwater/flood-damage rules, and property-maintenance requirements as applicable. Permits are required for new homes, mobile homes, modular homes, additions, carports, garages, storage buildings, gazebos, pools, decks, roofs, and interior remodeling. Cosmetic repairs such as painting and carpet are exempt. Detached residential accessory structures under 120 square feet are exempt from permitting but must be in the rear yard at least 8 feet from side and rear property lines. Confirm any additional narrow exemptions with Planning and Codes.
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.
