How Long Does It Take to Get a Building Permit Approved?

Direct answer: There is no defensible national building-permit approval range. Use the responsible agency's current measure for the exact project and review path, then account separately for intake, correction cycles, outside-agency reviews, and applicant response time. If that agency publishes no current measure, the duration is unknown.

What the official timelines actually show

Two current city programs illustrate why a single nationwide number is misleading:

These figures are examples, not promises for another jurisdiction. They show the questions to ask: What project category am I in? When does the review clock start? Is the number a goal, median, or 75th percentile? Does it include applicant correction time?

How to use official targets

Do not convert another agency's target into a national range. Use a published local measure only after matching its permit category, review-clock definition, and reporting period to your project. If the responsible agency publishes no current measure, treat the duration as unknown and plan around the review stages below rather than inventing a number.

The timeline has five separate clocks

1. Pre-application research. Parcel, zoning, overlays, adopted code, and required approvals are identified.
2. Intake. Staff checks whether the application, plans, and fee are complete enough to enter review. Some agencies do not start their target clock until intake is accepted and paid.
3. Initial review. Building, zoning, fire, utilities, drainage, transportation, health, or other reviewers evaluate the package.
4. Corrections and re-review. The applicant answers comments and uploads revised documents. Every unresolved comment can create another cycle.
5. Issuance. Final fees, contractor credentials, bonds, or related approvals are cleared before the permit is released.

Ask the department which clocks its published measure includes. A review target rarely means the permit will be in hand that many days after the applicant first starts preparing.

What most often extends approval

• The application uses the wrong jurisdiction, permit type, or project address.
• The site plan omits lot lines, setbacks, easements, existing structures, or proposed dimensions.
• Architectural, structural, energy, or trade sheets disagree with one another.
• Zoning, floodplain, shoreland, historic, fire, utility, septic, or access approval must be completed by another reviewer.
• A correction response fixes one sheet but not the related notes, calculations, or schedules.
• The applicant waits to pay an invoice or respond to comments.
• The project needs a public hearing or discretionary approval rather than an administrative permit.

Austin's official process explicitly notes that rejection comments must be resolved before approval and that the review step may repeat. Seattle similarly reports multiple review cycles and distinguishes government review time from time with the applicant.

How to build a defensible estimate

1. Confirm the issuing authority for the exact parcel; mailing city and permitting jurisdiction are not always the same.
2. Find the official page for the exact permit category and record the date you checked it.
3. Confirm whether the target covers intake, initial review, corrections, and issuance.
4. List every parallel approval and whether it can run concurrently.
5. Ask whether corrections are common for this project type, and model applicant-response time separately; do not assume a cycle the agency has not documented.
6. Do not schedule demolition, material delivery, or contractor mobilization against a target date as though it were an approval guarantee.

Before you submit

• Use the current application and checklist.
• Match the project description across every sheet and form.
• Show existing and proposed conditions on the site plan.
• Include the survey, structural information, energy documents, and trade plans the checklist requires.
• Resolve zoning and overlay questions before detailed construction drawings are finalized.
• Name one person to own reviewer comments and return a complete, coordinated response.

Check the timeline for your property

The fastest useful answer starts with the address and project—not a national average. Start a GovCodex Permit Check to identify the likely authority and approval path, then confirm the current review target on that agency's official site.

Frequently asked questions

Does the review clock start when I upload the application?

Not necessarily. Many agencies start the clock only after intake accepts the package and required fees are paid. Austin, for example, says the review time starts after the accepted submittal is invoiced, paid, and distributed.

Is an initial-review target the same as approval time?

No. An initial review can end with correction comments. Approval comes after every required reviewer is satisfied and issuance conditions are cleared.

Can I begin work while the permit is under review?

Do not begin permit-required work unless the issuing authority has granted a specific early-start authorization. A submitted application is not an issued permit.

What is the best way to shorten the process?

Choose the correct permit path, submit the current checklist in full, resolve zoning and outside-agency issues early, and answer every correction as one coordinated package. Those steps reduce avoidable cycles; they do not guarantee that an agency will beat its published queue.
