Quick answer: How long does a building permit take?
There is no single nationwide building permit timeline.
Simple residential projects can sometimes move through review relatively quickly, while additions, structural work, new construction and projects involving multiple departments can take much longer.
For planning purposes, think in terms of weeks for simpler projects and potentially months for more complicated projects. Your local permitting authority's current review schedule is more useful than a nationwide average.
If you are ready to start a home project, you probably have one question before anything else:
"How long will it take to get my building permit?"
The honest answer is that building permit processing times vary widely across the United States.
A small residential project with a complete application may move through review much faster than a large addition or new home that requires detailed plans, structural review and multiple approvals.
Local government workload also matters. Even two similar projects can have different timelines when they are submitted to different jurisdictions.
Current municipal guidance demonstrates this variation. For example, Portland publishes residential first-review goals of roughly 7 days for alterations and 15 days for additions and new construction. Arlington, Virginia publishes approximately 5 to 10 business days for several residential review paths. These are local review targets, not national guarantees.
That distinction matters.
A permit review time is also not necessarily the same as the total time from "I started planning" to "I have an approved permit."
What this guide covers
1. How Long Does a Building Permit Take?
A building permit can take anywhere from a relatively short period for simple work to several months for complicated projects.
The biggest mistake is looking for one number that applies to every homeowner.
There isn't one.
Simple projects
Complete applications and straightforward work may move through review more quickly.
Additions & remodels
More plans and code issues can mean additional review and corrections.
Complex projects
Large projects may involve multiple agencies, technical reviews or zoning issues.
The local department's published review times should always be treated as the starting point for your estimate.
2. Building Permit Timeline: What to Expect
A permit does not simply go from "submitted" to "approved."
There are usually several steps between preparing your project and receiving an issued permit.
Project preparation
You determine the scope of work, prepare plans and identify the applicable requirements.
Application submission
The application and required documents are submitted through the local process.
Completeness check
The authority may determine whether the application contains the required information.
Technical review
Reviewers examine the plans and project against applicable requirements.
Corrections, if required
You may need to correct plans or provide additional information.
Recheck or additional review
Revised plans may need another review.
Permit issuance
Once the applicable requirements are satisfied, the permit can be issued according to the local process.
This is why the phrase "permit review time" can be misleading. A department may publish a target for its first review, but the total time to approval can be longer if corrections or additional reviews are required.
3. How Long Do Simple Residential Permits Take?
Simple residential projects are usually easier to review when the scope is clear, the application is complete and the plans do not raise unusual issues.
Some jurisdictions have fast-track, express or over-the-counter paths for qualifying work.
For example, Arlington, Virginia currently publishes approximate residential review times of 5 business days for one standard alteration route and 10 business days for several other residential routes, with separate express options for eligible projects.
What makes a project easier to review?
- ✓ Complete application
- ✓ Accurate project information
- ✓ Clear plans
- ✓ Correct property information
- ✓ No unresolved zoning issue
- ✓ No missing supporting documents
- ✓ Quick response to reviewer questions
Even when a jurisdiction has a short published review target, that target should not be treated as a guaranteed permit issuance date.
4. How Long Can Complex Building Permits Take?
Larger or more complicated projects can take substantially longer.
Examples include:
For complicated projects, planning for several weeks is often more realistic than expecting an immediate approval. Some projects can extend into months when multiple reviews, corrections or special approvals are involved.
The more complicated the project, the less useful a simple "average permit time" becomes.
Use the actual review information from your jurisdiction and build extra time into your project schedule.
5. What Happens During Building Permit Review?
Understanding the review process makes it easier to understand why some permits move quickly while others take longer.
Application completeness
The department may first determine whether the application has the information and documents required to move forward.
Building-code review
Depending on the project, reviewers may examine structural details, life-safety issues, construction methods and other applicable requirements.
Zoning or planning review
The project may also need to satisfy local zoning rules such as setbacks, height, lot coverage or permitted use.
Specialty review
Certain projects may require additional review by other departments or agencies.
Correction review
If changes are requested, the revised documents may need to be reviewed again.
6. What Causes Building Permit Delays?
Not every permit delay is caused by the permitting department.
Homeowners and contractors can prevent many avoidable delays by preparing the application correctly.
Incomplete applications
Missing information can prevent a project from moving through review.
Missing plans
Required drawings or supporting documents may be needed before review can be completed.
Incorrect information
Conflicting dimensions, project descriptions or property information can create additional questions.
Zoning problems
A project may require changes if the proposed location or size does not meet zoning requirements.
Slow responses
Waiting to answer correction requests can add unnecessary time.
Department workload
Current staff workload can affect actual review times.
Kirkland's current permit-review guidance specifically identifies application accuracy and clarity, site conditions, availability of project contacts, staff workload and the extent of proposed work as factors that can affect actual review times.
7. How Much Time Do Permit Corrections Add?
There is no universal number of days that a correction request adds.
It depends on the correction.
A small clarification may be resolved quickly. A major plan change can require revised drawings, additional engineering and another round of review.
Think in review cycles
Instead of asking only "How long is the permit review?", ask:
"How long will the first review take, and what happens if corrections are required?"
This gives you a much more realistic project schedule.
8. How to Get a Building Permit Faster
You cannot control the permitting department's workload, but you can control how prepared your application is.
Confirm the requirements first
Know what the local authority expects before submitting.
Prepare complete plans
Missing information creates avoidable review problems.
Check zoning before submission
Identify setback, height or location problems early.
Double-check dimensions
Make sure drawings and application information agree.
Respond quickly
Do not leave correction requests unanswered.
Keep documents organized
Keep track of submitted plans, revisions and approvals.
Reduce the reasons your application can be sent back.
The fastest permit is not necessarily the one submitted first. It is often the one submitted correctly and completely.
9. Does the Permit Timeline Include Inspections?
Usually, you should think of permit approval and construction inspections as separate stages.
First, the permit application may be reviewed and approved.
Then, once construction begins, required inspections can occur at specified stages of the work.
Permit review
Determines whether the proposed work satisfies the applicable requirements.
Construction inspections
Check work during construction according to the local inspection process.
Therefore, if someone tells you that their permit took two weeks, that does not necessarily mean their entire construction process took two weeks.
10. How to Check Your Building Permit Status
Many local governments provide online permit-status tools.
If your jurisdiction provides one, you may be able to search using information such as:
Permit status labels can differ between jurisdictions. A status such as "under review," "corrections required," "approved" or "issued" can have specific meanings in the local system.
Don't panic if the status does not change every day
Permit departments may process applications in stages. A status remaining unchanged for a period does not automatically mean that the application has been rejected.

Does the building permit timeline include inspections?
Usually, the permit review and permit issuance are different from the construction inspection stage. A permit may be approved before construction begins, while required inspections take place during the project. The exact process depends on the jurisdiction and project.
Final Answer: How Long Does a Building Permit Take?
The most accurate answer is: it depends on your project and your local permitting authority.
Simple residential work may move through review relatively quickly when the application is complete and straightforward.
Additions, structural projects, new construction and projects involving multiple reviews can take much longer.
The biggest mistake is planning your construction schedule around an internet estimate that does not account for your property or jurisdiction.
The smartest approach
Check your local department's current review times, prepare a complete application, make sure your plans are accurate, and allow extra time for corrections or additional reviews.
A realistic permit schedule is not just about counting days. It is about understanding the entire process from preparation to approval.
If you are planning construction in 2026, research your property's requirements before you commit to a construction start date.
