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
2021 International Residential Code and 2021 International Building Code, including high-wind-region design requirements effective January 1, 2023; Louisiana State Uniform Construction Code and FEMA/flood-elevation requirements also apply.
Inspection lane
Apply and track permits through MGO Connect. The building procedures require benchmark, form-top, and final elevation documentation; the permit placard and reviewed plans must remain visible/on site. The building-permit process is generally 5-7 working days when no additional review is needed; Certificate of Occupancy is issued within 10 working days after final documentation is complete.
Minor-work playbook
N/A. The parish FAQ confirms owner-builder affidavits for a primary residence but does not publish a general minor/cosmetic building-work exemption list.
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
Apply and track permits through MGO Connect. The building procedures require benchmark, form-top, and final elevation documentation; the permit placard and reviewed plans must remain visible/on site. The building-permit process is generally 5-7 working days when no additional review is needed; Certificate of Occupancy is issued within 10 working days after final documentation is complete.
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.
No verified planning reference link is listed; ask the agency for the parcel-specific source.
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
Plaquemines Parish Government Permits, Planning & Zoning Department 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 Belle Chasse (504) 934-6195; Port Sulphur (504) 934-3610.
5-7 working days for permit processing when no additional reviews or approvals are needed; Certificate of Occupancy within 10 working days after final required documentation.

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.
