Ascension Parish Permits & Inspection Help

First, Check Who Issues Your Permit

Not every property with an Ascension Parish mailing address is permitted by the parish government. The responsible office depends on whether the property lies within an incorporated municipality or an unincorporated area.

If you are unsure which jurisdiction covers your property, provide the street address or parcel information to the appropriate government office before paying any application fee.

Which Building Permits Are Available?

Ascension Parish provides separate applications for new construction, changes to existing structures, trade work, and other regulated projects.

Do not assume a small project is automatically permit-exempt. Requirements may depend on size, use, location, structural changes, utilities, and local ordinances.

Find the applicable official forms on the Ascension Parish permitting page.

How to Apply for a Building Permit Online

1. Confirm the property jurisdiction. Check whether the work falls under Ascension Parish or a municipal permitting office. Have your site address ready.
2. Identify the correct application. Open the official permitting page and review the form for your project, such as Residential New Construction, Residential Addition, or Commercial Construction.
3. Prepare your plans and supporting documents. Review the requirements and assemble the applicable application, site plan, construction drawings, contractor details, and additional approvals.
4. Submit through MGO Connect. Select Apply for Building Permits on the parish website, sign in or create an account, and complete the available application steps. Upload plans and documents through the portal rather than sending them separately unless instructed otherwise.
5. Complete review and obtain approval. Respond to requests for corrections or additional documents, confirm assessed fees, and obtain the required permit before beginning regulated construction.

What Should You Prepare Before Applying?

• Property details: Street address, site location, property dimensions, and project description.
• Site plan: Existing and proposed structures, property boundaries, building placement, and setbacks where required.
• Construction plans: Floor plans, structural details, elevations, and relevant trade drawings according to project type.
• Contractor information: Applicable state and parish credentials and the authorized applicant’s details.
• Project valuation: Construction value or other information required for fee assessment.
• Additional approvals: Zoning, drainage, floodplain, health-department, or other documentation when applicable.

The official Plan Review page includes residential new-home requirements and separate guidance for metal buildings and pole barns. For example, the parish’s published metal-building requirements identify a site plan, engineered structural drawings, and foundation drawings, along with electrical, plumbing, and elevation documentation where applicable.

Ascension Parish Building Permit Fees

Ascension Parish publishes a permit fee schedule covering residential, commercial, trade, inspection, and licensing charges. The examples below come from its published schedule marked effective October 4, 2024. They are reference amounts, not a guarantee that every charge remains unchanged in 2026.

Residential new-construction valuation is calculated using the parish’s published method of $75 per square foot of living area. Additional valuation tiers apply above $100,000. Commercial permit fees depend on project valuation, with separate commercial plan-review and trade charges.

Example: A 2,000-square-foot residence would have a calculation valuation of $150,000 under that published $75-per-square-foot method. This is not the total permit fee; the applicable valuation bracket, separate trade permits, plan review, and other charges must still be considered.

Download the parish’s published fee schedule (PDF) and confirm current charges with the department before submitting payment. Do not use older fee schedules from other Louisiana municipalities.

Building Inspections: Scheduling & Requirements

Permitted construction must receive applicable inspections before concealed work is covered and before final approval. The parish supplies separate inspection-sequence documents for residences on slabs, residences on piers, metal buildings, and mobile homes.

Typical Inspection Stages

1. Foundation and footing: Required excavation, reinforcement, forms, and other components are checked before concrete placement.
2. Under-slab or under-floor: Applicable piping, conduits, equipment, and reinforcement are inspected before covering.
3. Rough-in and framing: Structural framing and required electrical, plumbing, and mechanical work are reviewed before concealment.
4. Final inspection: The completed work is assessed before applicable final approval or occupancy authorization.

The actual inspection sequence depends on the permit, construction method, and approved plans. Use the parish’s published inspection checklist for your project rather than treating the sequence above as universal.

How to Request an Inspection

1. Open the official Inspections page.
2. Select the applicable inspection-sequence document and confirm the required stage.
3. Access your permit in MGO Connect or contact the department for the accepted scheduling method.
4. Provide the permit number, property address, requested inspection type, and site-access information.
5. Wait for the required approval before concealing inspected work or proceeding beyond a mandatory inspection hold point.

If an inspection fails: Review the correction items, complete the necessary work, and arrange follow-up inspection. Do not assume that submitting a correction automatically authorizes continued construction.

Building Codes Applicable in 2026

Louisiana’s State Uniform Construction Code Council bulletin revised August 6, 2026 identifies these statewide code editions:

Louisiana amendments and applicable parish ordinances must also be considered. The state bulletin identifies January 1, 2027 as the planned effective date for the next ICC and NEC code review cycle; applicants filing in 2026 should not automatically apply the 2024 ICC editions.

Important Local Requirements Before Construction

Floodplain & Elevation Requirements

Flood exposure is an important consideration in Ascension Parish, especially near waterways and low-lying areas. Depending on the property and work, flood-zone review or elevation documentation may be required.

The parish provides separate flood-zone determination requests for existing structures, proposed construction or mobile-home relocation, and vacant land. Its published response allowance is up to 10 business days for a determination request.

Request Flood-Zone Information

Floodplain Coordinator: 225-450-1369. Check flood requirements before finalizing foundation or elevation plans.

Zoning, Drainage & Driveways

Before designing additions, accessory buildings, or commercial projects, check permitted land use, setbacks, easements, and drainage requirements. Building permit approval does not automatically replace separate zoning or floodplain approvals.

For a culvert serving a first-access driveway or frontage along a public right-of-way, the parish instructs applicants to contact its call center at 225-450-1200.

Commercial Construction & Occupancy

Commercial applicants should confirm plan review, occupancy classification, fire-safety requirements, and health-related approvals before construction. The parish’s permitting guidance states that commercial applicants must provide a Louisiana Department of Health approval letter before permit approval.

Ask the department how the health-review requirement applies to your project and whether additional State Fire Marshal or other agency approvals are needed. New businesses and changes in occupancy may require separate approvals before opening.

Contractor Licensing & Registration

The parish requires contractors working in the building, electrical, mechanical, and plumbing trades to meet applicable state and parish licensing requirements.

The parish’s published contractor application guidance lists the following supporting items:

• Applicable Louisiana contractor or residential license.
• General liability insurance documentation.
• A $5,000 surety bond as specified in the parish’s contractor guidance.
• Louisiana sales tax registration documentation.
• Completed parish contractor registration or renewal forms.

The published guidance also addresses special classifications and annual renewals. Because licensing documents can change, confirm the current requirements before relying on an older application form.

Permit Status, Changes & Final Approval

After submission, retain your permit or project reference number. Sign in to MGO Connect to review the available application record and any document or correction requests. If a status or review item is unclear, contact the Building Department with your permit number and property address.

Changes to approved plans may require revised documents or additional review. Likewise, passing an individual inspection does not necessarily mean the entire project is complete.

Before occupying or putting a completed building into use, confirm whether a final inspection, certificate of occupancy, or other authorization is required for that particular project.
