How long do permits take
Permit timing depends on your city, your project, and how complete your plans are. A simple interior remodel may move in a few days or weeks, while an addition, structural change, or new build can take several weeks to a few months, and sometimes longer.

Short answer: most permits take days to months, not hours
Homeowners often hear very different answers about permit timing because there is no single national rule. Local building departments set their own process, staffing, fees, review steps, and inspection schedules. That means the same kitchen remodel might be approved quickly in one town and take much longer in another.
As a broad U.S. estimate, a very simple permit for minor work may take a few business days to 2 weeks. A typical remodel with plan review may take about 2 to 6 weeks. Home additions, structural work, foundation work, major renovations, and new construction often take 1 to 4 months for review and approval, and complex projects can take longer. These are estimates, not quotes or guarantees.
What affects permit timing
The biggest factor is project complexity. If your work changes walls, beams, foundations, rooflines, plumbing, electrical, mechanical systems, or the home's footprint, the review is usually more detailed. New homes and additions often trigger zoning review, structural review, energy code review, and other checks.
The second big factor is how complete the application is. Missing drawings, unclear scope, incorrect forms, or plans that do not meet local code often lead to comments and resubmittals. Every correction cycle can add days or weeks. Good contractors and design professionals help reduce this risk, but no one can honestly promise approval by a certain date.
- Project type: cosmetic remodels are usually faster than additions or new construction.
- Local rules: each city or county has its own process, backlog, and staffing.
- Plan quality: complete, code-ready plans usually move faster than vague or incomplete drawings.
- Zoning issues: setbacks, height limits, lot coverage, parking, or historic rules can slow review.
- Special approvals: septic, well, grading, flood zone, coastal, or fire reviews may add steps.
- Seasonal workload: busy building seasons can create longer review times and inspection waits.
- Resubmittals: if reviewers ask for changes, the clock may restart or pause until updated plans are filed.
What it means for you as a homeowner
The practical takeaway is simple: do not plan your project around a best-case permit timeline. If you are trying to line up a move, a lease ending, school start dates, or temporary housing, build in cushion. Many projects are delayed not because anyone did something wrong, but because review comments, inspection scheduling, weather, or utility coordination take longer than expected.
It also means you should be careful with any contractor who says they can start major permitted work right away without clear approvals. In many cases, demolition, framing, structural changes, additions, and new construction need permits before work begins. Starting too early can create stop-work orders, fines, failed inspections, extra costs, and problems when you sell the home.
Mainstay Builders is a free matching service. We connect homeowners with licensed, bonded and insured general contractors for major residential projects. We do not issue permits, do not approve plans, and do not give legal, code, engineering, or design advice. Always verify a contractor's license, bond, insurance, and permit plan before signing a contract.
How permit timing works in practice
Most projects move through a series of steps. First, the scope is defined. Then drawings and application materials are prepared. Next, the permit package is submitted to the local building department. Reviewers may approve it, deny it, or send correction comments. If comments come back, the plans are revised and resubmitted. After approval, permit fees are paid, the permit is issued, and work can begin according to local rules.
That sounds straightforward, but the real timing can vary a lot. Some departments review in the order received. Some offer over-the-counter or same-day permits for very limited work. Others route plans to zoning, structural, planning, fire, public works, or health agencies. If a project needs multiple reviews, each department can add time.
Inspections matter too. Even after the permit is issued, work often cannot move to the next phase until inspections are passed. For example, foundation, framing, rough plumbing, rough electrical, insulation, and final inspections may all be required. If an inspection fails or the schedule is backed up, the project timeline extends.
- Step 1: define the work clearly.
- Step 2: prepare plans, drawings, and forms.
- Step 3: submit to the local authority.
- Step 4: respond to plan-check comments if needed.
- Step 5: pay fees and receive permit issuance.
- Step 6: schedule and pass required inspections during construction.
Common examples by project type
Small, non-structural projects can be faster, but many still need permits if plumbing, electrical, or mechanical work is involved. Replacing cabinets alone may not require much review in some places, but moving plumbing lines, electrical circuits, or walls usually changes that. Bathroom remodels often fall into this middle category.
Structural projects usually take longer. Removing load-bearing walls, changing beams, adding square footage, building decks with structural requirements, converting garages, finishing basements with code upgrades, or repairing major foundation issues often require more detailed drawings and review. New homes take the longest in many jurisdictions because they involve the most review categories.
Accessory structures and exterior work can also be unpredictable. A detached garage, large porch, retaining wall, major grading work, or fence in a regulated area may trigger separate rules. Historic districts, hillside zones, flood zones, wildfire-prone areas, and coastal regions often have added layers of review.
What to watch for before you sign with a contractor
A good contractor should speak plainly about permit timing. They should explain what they know, what they do not know yet, and what depends on your local department. Be cautious if someone gives a guaranteed approval date, says permits are unnecessary for clearly structural work, or suggests pulling a permit for only part of a larger job to move faster.
Ask who is responsible for preparing plans, submitting the application, paying permit fees, responding to corrections, and scheduling inspections. The contract should make these responsibilities clear. You should also confirm whether the contractor has experience with your city or county, but remember that local familiarity helps only so much. It does not override code or shorten every backlog.
- Verify the contractor is licensed, bonded and insured before signing.
- Ask whether your project needs zoning review, structural review, or other agency approvals.
- Ask what plans are included and who prepares them.
- Ask how resubmittals and correction comments will be handled.
- Ask for an honest timeline range, not a promise.
- Get permit responsibilities in writing.
How to reduce delays without cutting corners
You cannot control the building department's workload, but you can reduce avoidable delays. Start early. Be clear about your goals. Choose professionals who regularly handle permitted residential work. Make sure the project scope is complete before plans are submitted, because mid-stream changes can trigger new review comments or revised permits.
Keep your paperwork organized. Save permit numbers, receipts, revision notices, and inspection records. If English is not your first language, it is okay to ask for simple explanations and written summaries. You do not need to share immigration status or sensitive identification information to get matched with contractors through Mainstay Builders. Our role is to connect you with licensed, bonded and insured pros you can evaluate for yourself.
Most of all, avoid the temptation to skip permits to save time. Unpermitted major work can create expensive problems later. You may face penalties, need to open finished walls for inspection, have trouble with insurance claims, or be required to correct work that does not meet code.
Get matched with licensed contractors who can explain the permit path
If you are planning a new build, home addition, structural repair, or major renovation, Mainstay Builders can help you get matched with licensed, bonded and insured general contractors in the U.S. who handle projects like yours. We are a free matching service for homeowners. We do not build, design, engineer, or approve permits. We connect you with contractors so you can compare experience, communication, and approach.
When you speak with matched contractors, ask how they typically handle permit applications in your area, what parts of the process may take the longest, and what documents they need from you to get started. Then verify licenses, bond, and insurance, review the contract, and choose the pro you trust. That is the safest way to move forward with a permitted project.
Frequently asked questions
Can a contractor tell me exactly how long my permit will take?
Not honestly in most cases. A contractor may give you a reasonable range based on similar local projects, but the final timing depends on the building department, plan review comments, and any extra approvals required. Treat timelines as estimates, not guarantees.
Do all remodels need permits?
No, but many do. Cosmetic work may not need a permit in some places, while electrical, plumbing, mechanical, structural, and layout changes often do. Always verify local requirements before work starts.
Why do permit times vary so much from one city to another?
Each city or county has its own staffing, review process, backlog, and local rules. Some departments can issue simple permits quickly, while others route plans through multiple reviewers. Even within the same metro area, timing can be very different.
What usually causes permit delays?
Common causes include incomplete applications, unclear plans, code corrections, zoning issues, seasonal backlogs, and failed inspections later in the project. Scope changes after submission can also add time. Good preparation helps, but it cannot remove every delay.
Can work start while the permit is under review?
For major permitted work, usually no. Local rules differ, and a few limited early steps may be allowed in some areas, but you should never assume that means full construction can begin. Starting without proper approval can lead to fines, stop-work orders, and expensive corrections.
Does paying for expedited review guarantee fast approval?
No. In some jurisdictions, paid expedited review may shorten part of the process, but it does not guarantee approval by a certain date. If plans are incomplete or the project has code issues, comments and resubmittals can still slow things down.
Should the permit be in my name or the contractor's name?
That depends on local rules and the project setup. For major work, the licensed contractor often pulls the permit, but homeowners should still verify who is responsible and make sure the paperwork matches the actual scope. If anything is unclear, ask the local building department and read your contract carefully.
How can Mainstay Builders help if you do not issue permits?
We are a free matching service, not a contractor or building professional. We connect you with licensed, bonded and insured general contractors for major residential projects so you can compare options. You should still verify credentials, review the permit plan, and choose the contractor you want to hire.
