Codes, exemptions & field inspections
Build to the adopted code. Verify every exception.
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.
Inspection lane
Submit and manage permits through Monroe County Online Permitting Services; use the county Inspections page for scheduling directions. Inspectors call the contact number before arrival, and forms or affidavits are not accepted in the field.
Minor-work playbook
Understand what may be exempt—and what is not.
Effective July 1, 2026, certain limited single-family residential work valued under $7,500 may qualify after written county approval. It cannot be in an A or V flood zone, include electrical, plumbing, structural, mechanical, or gas work, or be divided into smaller projects to avoid permitting. Exemption approval does not waive Land Development Code requirements.
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.

Retain the approved plans, inspection approvals, correction responses, and final certificate or occupancy release with the property file.
Contractor verification
Verify the builder before the contract is signed.
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
Keep the parcel rules beside the building plans.
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.
