The short answer: In several major U.S. cities, obtaining a standard building permit now takes 4 to 12 months — and in some cases longer. San Francisco, New York City, Los Angeles, Chicago, Seattle, and Boston consistently rank among the slowest, driven by staffing shortages, layered review processes, and growing backlogs that surged after 2020.
If you're a contractor, developer, or homeowner planning a project, this delay isn't just frustrating — it's expensive. Carrying costs, rising material prices, and lost rental income can add tens of thousands of dollars to a project before a single shovel hits the ground.
This guide breaks down which cities are the worst, why permits stall, and what you can realistically do to move your application forward faster.
Why Building Permits Take So Long in Major Cities
Permit delays rarely come down to one cause. In most slow cities, several factors stack on top of each other:
- Staffing shortages — Many building departments lost experienced reviewers during the pandemic and never fully replaced them.
- Layered reviews — A single project may need sign-off from planning, zoning, fire, public works, and environmental departments.
- Discretionary approvals — Projects requiring public hearings or design review add months before construction review even begins.
- Outdated software — Some cities still process applications partly on paper or through systems that don't talk to each other.
- Post-pandemic backlog — A surge in renovation and ADU applications overwhelmed departments already short-staffed.
- Community opposition — Appeals and neighborhood objections can freeze a permit indefinitely.
The result: even a straightforward kitchen remodel or small addition can sit in queue for months before a reviewer opens the file.
Cities With the Longest Permit Wait Times
The table below reflects typical timelines reported by contractors and public data for standard residential and light commercial permits. Actual times vary widely by project type, zoning district, and completeness of the application.
| City | Typical Wait (Simple Residential) | Main Bottleneck |
|---|---|---|
| San Francisco, CA | 6–12+ months | Discretionary review, planning hearings |
| New York City, NY | 4–10 months | Multiple agency sign-offs, DOB backlog |
| Los Angeles, CA | 3–8 months | LADBS staffing, plan check queues |
| Chicago, IL | 3–7 months | Zoning review, aldermanic prerogative |
| Seattle, WA | 3–6 months | Design review, SEPA environmental checks |
| Boston, MA | 2–6 months | Neighborhood design review, ISD |
| Portland, OR | 2–5 months | BDS turnover, inspection scheduling |
| Washington, DC | 2–5 months | DCRA restructuring, historic review |
Note: Timelines are approximate and based on publicly reported averages. Always check your city's current permit dashboard for real-time estimates.
What Makes San Francisco and New York the Worst
San Francisco: The Discretionary Review Trap
San Francisco's permitting problem isn't just about volume — it's about process. Almost any project that changes the exterior or adds square footage can be pulled into Discretionary Review, a hearing where a single neighbor's objection can delay a permit by 6 to 12 months.
Even projects that avoid review face a planning department that has struggled with turnover. Contractors routinely report waiting weeks just to get a response to a clarifying question.
Realistic scenario: A homeowner in Noe Valley wants to add a second-story bedroom. The plans are straightforward, but a neighbor files for discretionary review. The project goes to a Planning Commission hearing, gets continued twice, and finally receives approval — nine months after the initial application.
New York City: Too Many Agencies, One Project
In NYC, a simple renovation can require approval from the Department of Buildings (DOB), the Department of Transportation, the Fire Department, and sometimes Landmarks Preservation. Each agency has its own queue, and they don't always coordinate.
DOB's plan review backlog has improved from its worst days, but contractors still report 4 to 10 months for anything beyond a minor alteration. Projects in historic districts or those needing a variance can take a year or more.
The Real Cost of Waiting
Permit delays aren't just an inconvenience. They carry direct financial consequences:
- Carrying costs — Mortgage interest, insurance, and property taxes continue during the wait.
- Material price risk — Lumber, steel, and labor costs can rise significantly over six months.
- Lost revenue — Rental units sit empty; commercial spaces can't open.
- Contractor scheduling — Good crews book other jobs; you may lose your builder.
- Permit expiration — Some cities require you to start work within a set period or reapply.
For a mid-size project, six months of delay can easily add $20,000 to $80,000 in combined costs — often more than the permit fees themselves.
How to Speed Up Your Permit (Realistically)
You can't fix a city's backlog, but you can avoid becoming a victim of it. These steps consistently help:
- Submit a complete application the first time. Missing documents are the #1 cause of delay. Use the city's checklist and double-check every item.
- Hire a local expedititor or permit runner. In slow cities, experienced expediters know reviewers, common rejection reasons, and how to push files forward.
- Schedule a pre-application meeting. Many cities offer this free or low-cost. It surfaces problems before you submit.
- Avoid discretionary review if possible. Design within existing zoning envelopes. If you must trigger review, hire a land-use attorney early.
- Respond to comments within 24 hours. Every day you wait to reply adds days to the back of the queue.
- Use over-the-counter permits when eligible. Simple repairs, water heaters, and some electrical work can be approved same-day in many cities.
- Consider phased permits. Some cities allow foundation or demolition permits while the full project is under review.
- Track your application online. Don't assume it's moving. Check the portal weekly and follow up politely but persistently.
Cities That Are Actually Getting Faster
Not every city is stuck. Some have made real improvements:
- Austin, TX — Moved to a digital review system and now offers same-day permits for some residential work.
- Houston, TX — No zoning and a relatively streamlined permitting process make it one of the fastest large cities.
- Phoenix, AZ — Invested in online permitting and reduced review times for standard residential projects.
- Denver, CO — Offers a "quick permit" program for simple projects, though larger reviews still take months.
The pattern: cities that invest in digital infrastructure, delegate more decisions to staff (rather than hearings), and publish clear timelines tend to perform better.
Frequently Asked Questions
Which U.S. city has the longest building permit wait time?
San Francisco is widely considered the slowest for residential projects, with typical timelines of 6 to 12 months or more when discretionary review is involved. New York City and Los Angeles follow closely.
Can I legally start work before my permit is approved?
No — with very few exceptions (like emergency repairs), starting work without a permit is illegal and can result in fines, stop-work orders, and required demolition of completed work. Always wait for approval.
How much does a building permit cost?
Permit fees vary by city and project value, typically ranging from a few hundred dollars for minor work to several thousand for new construction. The bigger cost is usually the delay, not the fee itself.
What is an expediter and do I need one?
An expediter is a professional who manages permit applications on your behalf. In slow cities like San Francisco, New York, or Chicago, an experienced expediter can save months by avoiding common mistakes and knowing how to navigate the system.
Do ADUs get approved faster?
Some cities, including California jurisdictions, have streamlined ADU reviews under state law. However, even these can take 2 to 4 months in practice. Check your local rules — ADU-specific pathways are often faster than standard residential permits.
What happens if my permit expires?
Most permits expire if work hasn't started within 6 to 12 months, or if work stops for a set period. You may need to reapply, pay fees again, and go through review a second time. Mark your expiration dates.
The Bottom Line
Permitting delays in major cities are a structural problem — not something you can wish away. The cities with the worst timelines share common traits: fragmented review processes, discretionary hearings, and understaffed departments.
But you're not powerless. Submitting a complete application, hiring local expertise when needed, and staying on top of your file can shave months off the process. In a system this slow, preparation is the only real shortcut.
If you're planning a project, start the permit process earlier than you think you need to. And if you're choosing where to build or invest, factor permitting timelines into your budget and schedule from day one.
Next step: Check your city's online permit dashboard for current processing times, or consult a local expediter before you submit your next application.
