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
2018 Kentucky Residential Code (KRC) for residential work; commercial work is reviewed under the Kentucky Building Code (KBC), including applicable Kentucky electrical and other adopted standards.
Inspection lane
Required inspections vary by project and include footer/post-hole, rough framing/mechanical, insulation, above-ceiling or fire-wall where applicable, and final building inspections. Call the inspector at least 24 hours before a footing inspection; the applicant or electrician must call for rough-in and final inspections. Use the official Required Building Inspections sheet: https://trimblecountyky.gov/wp-content/uploads/Required-Building-Inspections_2026.pdf. Contact Matt Dunaway at (502) 639-3218, Jerry Dunaway at (502) 639-3428, or the Fiscal Court at (502) 255-7196.
Minor-work playbook
The zoning ordinance exempts routine maintenance; alterations to existing buildings with replacement value of $500 or less; service connections to publicly owned and operated utilities; improvements required by an approved preliminary subdivision or planned-development plat; and structures other than signs containing less than 576 square feet. Confirm whether a project is exempt from the newer building-inspection program before starting work.
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
Required inspections vary by project and include footer/post-hole, rough framing/mechanical, insulation, above-ceiling or fire-wall where applicable, and final building inspections. Call the inspector at least 24 hours before a footing inspection; the applicant or electrician must call for rough-in and final inspections. Use the official Required Building Inspections sheet: https://trimblecountyky.gov/wp-content/uploads/Required-Building-Inspections_2026.pdf. Contact Matt Dunaway at (502) 639-3218, Jerry Dunaway at (502) 639-3428, or the Fiscal Court at (502) 255-7196.
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
Trimble County Building Division and Trimble County Planning & Zoning Commission is the identified county-level authority for this profile. Confirm that the property is in its service area before filing.
No verified online portal was located in the reviewed public materials. Contact Trimble County Fiscal Court/Planning & Zoning: (502) 255-7196 ext. 800; Building Inspector Matt Dunaway: (502) 639-3218; Electrical Inspector Jerry Dunaway: (502) 639-3428; Planning & Zoning Administrator Zoe Kemper: (502) 665-1507 and request the current application route before preparing a final submittal.
N/A. The current building program does not publish a standard review timeline; the zoning ordinance says three business days is reasonable under normal circumstances for zoning applications.

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.
