Construction permit application: Steps you should know

Applying for a construction permit before any major renovation is crucial to ensure your building project meets safety and zoning regulations. Whether you’re a homeowner planning a remodel or a contractor handling a large-scale build, knowing how to fill out a construction permit application and understanding how long it takes to review can save you time and frustration. And prevent potential legal issues.​

What is a construction permit?

A construction permit, often referred to as a building permit, is an official approval issued by a local government agency that allows you to proceed with construction or remodeling work on your property. 

Note that these permits ensure that projects comply with:

• Building codes (safety standards)
• Zoning laws (land use regulations)
• Environmental guidelines

When do you need a permit?

Most major projects require a permit, including:

• New construction (homes and commercial buildings)
• Structural changes (removing walls or adding rooms)
• Electrical, plumbing, or HVAC system updates
• Roof replacements (in some areas)
• Installation of large decks, fences, or outdoor sheds

Small repairs (such as painting or minor flooring) usually don’t need one. However, you must always check the local rules.

How to fill out a construction permit application?

Filling out a construction permit application correctly will help avoid delays or rejections. Below are the essential steps to ensure your submission is complete and compliant. For more detailed instructions, it’s best to refer to your local building department’s guidelines.​

Step 1: Identify the correct permit type

Before filling out any forms, confirm which building permits you need. Common types include:

• New construction permit: For building a house, garage, or commercial structure
• Remodeling/renovation permit: Required for structural changes (e.g., removing load-bearing walls, adding rooms)
• Electrical, plumbing, or mechanical permit: Needed for system upgrades or installations
• Demolition permit: For tearing down existing structures
• Accessory Dwelling Unit (ADU) permit: For granny flats, mother-in-law suites, or backyard cottages

Where can you find the right application form?

• Visit your city/county building department website and search for “building permit application”.
• Call the permitting office to confirm the applicable form for your project.

Step 2: Gather required documentation

Most applications require:

A. Property and ownership details

• Proof of ownership: Deed, title, or lease agreement
• Property survey/Site plan: Showing property lines, existing structures, and proposed work
• Legal description of the real estate: Found on your property tax statement

B. Construction plans and drawings

• Architectural drawings: For new builds or major renovations
• Structural engineering report: If modifying load-bearing elements
• Energy compliance forms: Some states require energy efficiency documentation

C. Contractor and professional credentials

• Contractor’s license number (if hiring a professional)
• Workers’ compensation insurance (for commercial projects)
• Notarized affidavit (if acting as an owner-builder)

Keep in mind that missing documents are the #1 reason for building permit delays. So get this step correct in the first go.  

Step 3: Complete the construction permit application form

Be specific—vague descriptions (e.g., “home renovation”) may trigger requests for more info. If you are unsure, consult a permit expeditor or contractor for this part.

Most applications ask for:

Project and property information

• Project address
• Parcel/Tax ID number
• Type of work (new construction, remodel, repair, etc.)
• Estimated project cost (this affects permit fees)

Applicant and contractor details

• Owner’s name and contact info
• Contractor’s license number (if applicable)
• Design professional’s info (architect/engineer)

Scope of work description

• Detailed summary (e.g., “Two-story rear addition, 500 sq. ft., with new bathroom”)
• Building materials and methods (e.g., wood framing, concrete foundation)

Step 4: Submit and pay fees

You can submit the application form in any of the following ways:

• Online (many cities now use online portals for convenience)
• In-person (at the building department office)
• By mail (this is less common; check if it’s allowed in your state)

Permit fees are typically based on:

• Project valuation (higher cost = higher fees)
• Square footage of the building
• Type of work (please note electrical/plumbing may have separate fees)

Step 5: Await review and respond to corrections

After your submission, there is:

1. Initial screening: The office checks for completeness (1–3 days)
2. Plan review: Engineers/planners assess compliance (2–8 weeks)
3. Corrections, if needed, are made at this point: You’ll receive a revision letter listing required changes
4. Final approval: Once compliant, you’ll receive the permit

How long does it take to review a construction permit application?

Several factors influence review time. These include:

• Completeness and accuracy of the application
• Specific site conditions or property issues
• Availability of contacts (owner, architect, or engineer) to respond to reviewer comments
• Current workload and staffing levels of the building department

Minor renovations or straightforward projects may receive approval within a few days to a couple of weeks.​ But complex projects or larger renovation projects can take several weeks to months. For instance, in Seattle, initial reviews for simple permits are typically completed in 2-3 weeks, while complex permits may take up to 8 weeks. By the way, some cities offer expedited review for an extra fee.

What are some pro tips to consider before applying for a construction permit? 

• Check local requirements. Building codes and permit requirements can vary significantly between jurisdictions. Always verify with your local building department.​
• Prepare thoroughly. Ensure all sections of the application are completed accurately and all required documents are attached.​
• Stay informed. Keep track of your application’s status and be responsive to any requests for additional information.​
• Follow up weekly if the review takes longer than estimated.
• Respond quickly to revision requests to avoid delays.

Key takeaway

By understanding the construction permit application process and preparing accordingly, you can facilitate a smoother approval process and ensure your project complies with all necessary regulations.
