Getting a building permit is a process that allows a government permitting authority to review certain proposed construction work for compliance with applicable building codes, zoning requirements, safety standards, and other regulations. The process is common across the United States, but there is no single nationwide building permit application or approval procedure.

The exact requirements depend on the property's location, the type and size of the project, the applicable codes, and the authority responsible for permitting. A homeowner building an addition may need detailed architectural and structural plans, while a smaller alteration may require a simpler application. Some projects may also require separate electrical, plumbing, mechanical, zoning, demolition, or specialized approvals.

If you're trying to determine which requirements apply to your specific project, Zermit AI can help you research the relevant permit information before you begin the application process.

How Do You Get a Building Permit?

The typical process involves identifying the correct jurisdiction, determining which permits are required, checking zoning requirements, preparing plans and supporting documents, submitting the application, paying applicable fees, completing plan review, responding to corrections, receiving approval, and completing required inspections.

Although the sequence is broadly similar, individual jurisdictions can use different application portals, documentation standards, review procedures, fee structures, and inspection processes. The local authority having jurisdiction should therefore be treated as the final source for project-specific requirements.

Step 1: Identify the Authority Having Jurisdiction

The first step is determining which government authority handles permitting for the property.

Depending on where the property is located, permitting may be administered by a city, county, municipality, or another designated authority. This is particularly important in areas where a property may have a mailing address associated with one community but fall under a different permitting jurisdiction.

Start with the property's exact address and determine which building department or permitting authority has jurisdiction.

This prevents a common problem: preparing an application based on the requirements of the wrong city or county.

Step 2: Determine Which Permits Your Project Requires

Before completing an application, identify all of the permits and approvals that may apply.

A project could potentially require a:

• Building permit
• Electrical permit
• Plumbing permit
• Mechanical permit
• Zoning approval
• Demolition permit
• Fire-related approval
• Specialized permit

For example, a major home renovation may involve structural changes, electrical modifications, plumbing relocation, and HVAC work. Treating the project as a single "renovation permit" could result in missing required approvals.

The correct approach is to evaluate every component of the proposed work.

Step 3: Check Zoning Before Finalizing the Project

Building-code compliance and zoning compliance are related but different concepts.

Zoning regulations can govern:

• What a property can be used for
• Building setbacks
• Building height
• Lot coverage
• Density
• Parking
• Accessory structures
• ADUs
• Property development
• Historic or special districts

A proposed project can satisfy construction requirements while still violating a zoning restriction.

For this reason, zoning should be checked early, particularly for additions, new structures, conversions, ADUs, changes of use, and substantial exterior modifications.

Step 4: Prepare Your Plans and Supporting Documents

The documents required depend on the project's complexity and the jurisdiction's application requirements.

A permit application may require some combination of:

• Site plans
• Floor plans
• Elevations
• Construction drawings
• Structural plans
• Engineering calculations
• Electrical plans
• Plumbing plans
• Mechanical plans
• Energy documentation
• Product specifications
• Property information
• Contractor information
• Project valuation

Complex projects may require documents prepared or sealed by licensed professionals.

Before submitting, compare your package against the jurisdiction's current checklist so that missing documents do not create avoidable delays.

Step 5: Complete the Building Permit Application

Once you understand the requirements and have prepared the documents, complete the permit application.

Applications commonly request information about:

• Property address
• Property owner
• Applicant
• Contractor
• Project scope
• Construction type
• Project valuation
• Proposed work
• Supporting plans

Use a precise description of the work. A vague description can make it harder for reviewers to understand the full scope and determine which requirements apply.

Step 6: Submit the Application

Many permitting authorities now provide online application portals, while others use in-person or hybrid submission procedures.

When submitting, make sure you provide the complete application package in the format requested by the jurisdiction. Some authorities impose specific requirements for file formats, drawing scales, naming conventions, signatures, or supporting documents.

After submission, retain confirmation and application information so you can track the project's status.

Step 7: Pay the Required Permit Fees

Permit fees vary substantially across the United States because each jurisdiction establishes its own fee structure.

Depending on the project, costs may include:

• Building permit fees
• Plan-review fees
• Inspection fees
• Technology or administrative fees
• Specialized permit fees
• Additional review charges

Some jurisdictions calculate fees based on project valuation, square footage, construction type, permit category, or other factors.

Because fee schedules change and vary by location, always check the current fee information applicable to your project rather than relying on a generic national estimate.

Step 8: Wait for Plan Review

Once the application is submitted, the permitting authority reviews the plans and documentation for compliance with applicable requirements.

Depending on the project, reviewers may examine:

• Building-code compliance
• Structural design
• Zoning
• Fire and life safety
• Electrical requirements
• Plumbing requirements
• Mechanical systems
• Energy requirements
• Accessibility
• Site conditions

A complex project may pass through multiple review disciplines before approval.

Step 9: Respond to Corrections

A permit application does not necessarily receive approval during its first review. If reviewers identify issues, the jurisdiction may issue correction comments requesting additional information, revised drawings, calculations, or changes to the proposed design.

Read each correction carefully and address every requested item. Submitting an incomplete response can lead to another review cycle and extend the approval timeline. For complex projects, the correction process can be one of the most significant factors affecting the overall permitting schedule.

Step 10: Receive the Building Permit

Once the application satisfies the applicable requirements and all required fees and approvals have been completed, the jurisdiction can issue the building permit.

Before beginning construction, review the issued permit and associated documents carefully. Confirm the:

• Approved scope
• Approved plans
• Permit conditions
• Required inspections
• Expiration information
• Additional approvals or conditions

Application submission is not the same as permit approval. Construction that requires a permit should not begin merely because an application has been filed.

Step 11: Follow the Approved Plans During Construction

Once work begins, construction should follow the approved plans and permit conditions.

If you decide to make significant changes during construction, determine whether revised plans or additional approval are required before implementing the change.

Changing the scope without approval can create problems during inspection and final approval.

Step 12: Schedule Required Inspections

Inspections allow the permitting authority to verify that regulated work has been constructed according to the approved plans and applicable requirements.

Depending on the project, inspections may cover stages such as:

• Foundation
• Framing
• Electrical
• Plumbing
• Mechanical
• Insulation
• Drywall
• Final inspection

The exact inspection schedule varies by jurisdiction and project type.

A key rule is to avoid covering work that must be inspected before the required inspection has taken place.

Step 13: Complete Final Inspection and Approval

Once the construction is complete, the project may require a final inspection.

Depending on the project, the jurisdiction may also issue or require a certificate of occupancy, final approval, completion documentation, or another form of closeout.

Keep copies of the permit, approved plans, inspection records, and final documentation. These records can become important later if the property is sold, refinanced, renovated, or inspected.

How Long Does It Take to Get a Building Permit?

There is no universal U.S. building permit processing time because permit timelines depend on jurisdiction, project complexity, application completeness, review workload, and the number of correction cycles required.

A simple project with complete documentation may move more quickly than a complex addition or commercial project requiring structural, zoning, fire, environmental, or other specialized review.

If timing matters, check the permitting authority's current processing information before committing to a construction schedule.

How Much Does a Building Permit Cost?

The cost of a building permit depends on the jurisdiction and project. Fees may be calculated using project valuation, square footage, construction type, permit category, plan-review requirements, inspections, or other local formulas.

There is therefore no reliable single "U.S. building permit cost."

For an accurate estimate, identify the jurisdiction first and then review its current fee schedule for the specific project type.

What Can Delay a Building Permit?

Several issues can extend the permitting process, including incomplete applications, missing drawings, inaccurate project information, zoning conflicts, code deficiencies, engineering issues, multiple review departments, and slow responses to correction notices.

One of the most effective ways to reduce avoidable delays is to understand the jurisdiction's requirements before submitting the application, rather than discovering documentation requirements after the first review.

Can You Get a Building Permit Without a Contractor?

Whether a homeowner can apply for a permit without a contractor depends on the jurisdiction and type of work.

Some jurisdictions allow property owners to act as permit applicants for work on their own property, while other projects may involve licensing requirements or restrictions on who can perform specific work.

Always check the local rules before assuming that a homeowner can obtain or perform the work under a permit.

What Happens If You Build Without a Required Permit?

If a permit was required but construction began without it, the property owner may face enforcement action depending on local regulations. Potential consequences can include stop-work orders, penalties, inspections, additional fees, correction requirements, or other measures.

Unpermitted construction can also complicate future property transactions and subsequent permitting.

If you discover existing unpermitted work, contact the relevant permitting authority and ask what process is available for bringing the work into compliance.
