Codes, exemptions & field inspections
This guide translates the available agency record into a preconstruction checklist for structural scope, minor work, and inspection release. The adopted code and the issuing official control when a field condition is disputed.
Regulatory framework
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.
Inspection lane
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.
Minor-work playbook
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.
Field rule
A permit exemption generally addresses one narrow construction trigger. It does not automatically waive zoning, land-use, floodplain, shoreline, fire, energy, electrical, utility, septic, or right-of-way requirements. Obtain written confirmation when the project involves a new structure, structural alteration, change in occupancy, or concealed work.
Inspection pipeline
Request with lead time
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.
Preserve access
Do not cover framing, reinforcement, wiring, piping, damp-proofing, or life-safety work until the required inspection has been completed and documented.
Close the record
Retain the approved plans, inspection approvals, correction responses, and final certificate or occupancy release with the property file.
Contractor verification
Use the state licensing system to verify active registration, trade credentials, bond status, and liability coverage where available. Match the legal business name to the proposal and permit application.
Planning reference
A building permit is only one part of statutory compliance. Check the local zoning, ordinance, map, or land-use reference before finalizing setbacks, height, lot coverage, access, drainage, or accessory structure placement.
Open planning reference ↗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.

Field sequencing matters
Code compliance is not only a plan-review exercise. Footings, reinforcement, framing, fireblocking, wiring, piping, insulation, weather protection, and life-safety systems each have points where the work must remain accessible. Build the inspection calendar into the trade schedule instead of treating it as a final administrative step.
When a project qualifies for a narrow minor-work exemption, keep a written explanation of why it qualifies and confirm that related zoning, utility, fire, energy, or environmental rules do not create a separate approval requirement.
Closeout file
Keep the approved plan set, inspection approvals, correction responses, contractor license verification, final certificate, and any occupancy release together. A clean record protects the owner, builder, lender, insurer, and future buyer.
