Huntsville Building Permits — Cost, Timeline & Process

The City of Huntsville Inspection Department administers building permits, plan review, and inspections for work inside Huntsville city limits. Projects can also require review by Planning, Zoning, Engineering, Traffic Engineering, Water Pollution Control, Natural Resources, the City Clerk, or Legal depending on scope.

Current Adopted Codes

The City's current Inspection requirements page lists these technical codes:

• 2018 International Building Code (IBC)
• 2018 International Residential Code (IRC)
• 2018 International Mechanical Code (IMC)
• 2018 International Plumbing Code (IPC)
• 2018 International Fuel Gas Code (IFGC)
• 2018 International Existing Building Code (IEBC)
• 2018 International Swimming Pool and Spa Code (ISPSC)
• 2015 International Energy Conservation Code (IECC / Alabama Energy Code)
• 2017 National Electrical Code (NEC)

Huntsville Fire & Rescue separately lists the 2021 International Fire Code (IFC) with the City's stated appendix exclusions. Use the City's current code page rather than assuming Huntsville has moved to the 2021 IBC/IRC family.

How to Submit Plans

All commercial and residential projects that require plan approval are submitted through Huntsville ePlans Review.

The ePlans system is used to:

• submit the permit application and PDF plans;
• track review status;
• receive marked-up plans and review comments;
• upload revisions for a correction cycle; and
• receive the Ready for Issuance notice after approval.

The City specifically warns applicants not to delete prior plan files when resubmitting revisions because doing so can force a full resubmission.

Minor residential repairs or alterations that do not require plan review may qualify for a walk-in permit. Residential permits submitted through ePlans must still be picked up in person after processing and approval.

Permit Costs

Huntsville publishes its current building-permit fee formulas.

For a new single-family dwelling:

1. heated square footage × $15.00;
2. unheated square footage × $7.50;
3. add those values and multiply the total by 0.0055.

For other building permits, the City states that the permit is calculated from the total contracting price × 0.0055.

Electrical, plumbing, gas, and mechanical work requires the appropriate separate trade permits. Always use the current City fee page when budgeting because the published formula can be amended.

Review Time

There is no single official "2–4 week" review promise that applies to every Huntsville project on the City permit pages used for this guide.

Review time depends on:

• project type and complexity;
• whether the submission is complete;
• the number of City departments that must review it;
• zoning, engineering, floodplain, or other approvals; and
• correction and resubmittal cycles.

Use the live status in ePlans and contact Inspection Services at 256-427-5331 when a project schedule depends on current review workload.

Flood Hazard Areas

The City gives projects in FEMA Special Flood Hazard Areas a different workflow.

Its permit page states that:

• a project located in a FEMA Special Flood Hazard Area must be submitted in person; and
• building permits and most standalone trade permits require a Flood Development Permit (FDP) before other permit approval.

Use the City's GIS flood layer and confirm the requirement with Inspection Services or Engineering before filing.

Typical Permit Process

1. Confirm the parcel's zoning district and any overlay or special approval.
2. Determine whether the project requires plan review.
3. Prepare the permit application and required PDF drawings.
4. Submit projects requiring plan approval through ePlans.
5. Respond to departmental review comments and upload revisions without deleting prior files.
6. After approval, follow the Ready for Issuance instructions and pay applicable fees.
7. Keep the issued permit and approved documents available at the job site.
8. Schedule and pass the required inspections before final approval or occupancy.

Special Reviews

Some projects require additional documentation before permit issuance. Examples listed by the City include:

• Board of Zoning Adjustment approvals;
• Planning Commission Location, Character and Extent approval for qualifying public projects;
• Research Park Board approval for projects in Research Park districts;
• floodplain approval;
• landscaping/photometric plans for qualifying commercial development; and
• Natural Resources review for certain demolition, renovation, or addition work.
