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
Pennsylvania Uniform Construction Code (UCC), 34 Pa. Code Chapters 401-405 and referenced current ICC codes as adopted by Pennsylvania, enforced by the applicable municipality or its certified third-party code agency. Allegheny County separately administers county health and housing standards and certain subdivision/land-development reviews.
Inspection lane
Contact the municipality or its certified UCC code official where the work is located; Allegheny County does not schedule general building inspections countywide. Municipal inspection procedures, contacts, and appointment requirements vary.
Minor-work playbook
Exemptions are controlled by the applicable municipality and Pennsylvania UCC. Emergency repairs or equipment replacements may proceed without a prior permit only when the UCC application is submitted to the building code official within three business days; other minor-work exemptions must be confirmed locally. Zoning, floodplain, sewer/septic, and other approvals may still apply.
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
Contact the municipality or its certified UCC code official where the work is located; Allegheny County does not schedule general building inspections countywide. Municipal inspection procedures, contacts, and appointment requirements vary.
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
This record is marked Municipal 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 Allegheny County general information: 412-350-4636 or 800-581-9145; county planning: 412-350-1030; local building/code official varies by municipality.
N/A; review and inspection timelines are set by the municipality or its third-party UCC agency. Pennsylvania state expedited plan review is available within 7 days when requested with the applicable fee.

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.
