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, including applicable 2021 ICC editions for 2026 permits. Delaware County Planning provides advisory review of subdivisions, land developments, and ordinances; its official guidance directs building-permit questions to the municipality’s code-enforcement officials.
Inspection lane
Contact the city, borough, or township where the work is located to identify its building-code official, submit the UCC application and plans, and schedule inspections. Delaware County Planning’s Act 247 review and UCC appeal-board functions do not replace municipal permit issuance or routine inspections.
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 application is submitted to the building code official within three business days. Local ordinances may exempt normal maintenance or minor repairs that do not alter a structure; confirm all minor-work, zoning, floodplain, sewage, driveway, and occupancy requirements with the municipality.
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 city, borough, or township where the work is located to identify its building-code official, submit the UCC application and plans, and schedule inspections. Delaware County Planning’s Act 247 review and UCC appeal-board functions do not replace municipal permit issuance or routine inspections.
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 Delaware County Planning Department: 610-891-5200; local building/code official varies by municipality.
Pennsylvania UCC generally requires a building code official to grant or deny a complete permit application within 30 business days of filing; actual timing varies by municipality, code agency, project type, and completeness.

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.
