How long will your commercial project’s permit actually take? If you are an architect or project manager working across multiple jurisdictions, the honest answer is: it depends on factors most teams do not assess until the schedule is already at risk. Permit review timelines in the United States range from three weeks to eighteen months depending on the jurisdiction, project type, and entitlement status.
That variance is not a minor planning variable. It is one of the most consequential risks on a complex commercial project. Burnham Nationwide helps project teams forecast and manage that risk across jurisdictions, drawing on over 30 years of permitting experience and local expertise in markets from Chicago to Los Angeles.
This guide covers the primary drivers of permit timeline risk, how to assess jurisdiction-specific delay factors before you submit, and the strategies that protect your construction schedule when approvals take longer than planned.
Every week a permit is delayed costs money. Carrying costs on land, idle construction crews, expiring rate locks, and missed lease-up windows compound quickly. On a $2 million project with 8% financing, each month of permit delay adds roughly $13,000 in interest alone, before accounting for opportunity cost or contractor remobilization fees.
The challenge is that most project teams treat permitting as an administrative task rather than a schedule-critical path item. They estimate timelines based on past experience in a single jurisdiction and apply that assumption everywhere. On a multi-site commercial rollout, that approach breaks down at the first unfamiliar building department.
A 2026 report from the New York State Comptroller’s office found that the NYC Department of Buildings is experiencing slowdowns in responsiveness for both development and inspection activities due to staffing and budget constraints. That pattern is not unique to New York. Building departments across the country are managing elevated demand with limited staff, and the result is longer, less predictable review cycles.
Permit timelines are not random. They are driven by a set of identifiable factors that vary by location, and understanding those factors is the first step toward managing the risk they create.
The single largest variable in permit review duration is the jurisdiction itself. Tier 1 markets such as New York City, Los Angeles, and San Francisco have complex multi-department review processes, design review boards, and environmental requirements that push timelines to nine months or longer.
Tier 3 markets, including many Texas and Florida suburbs, may issue permits in three to eight weeks for the same project type.
Department staffing levels play a direct role. When a building department is understaffed, even straightforward plan reviews take longer. Some jurisdictions have addressed this through third-party review programs; others have not. Knowing which category your target jurisdiction falls into is essential for accurate schedule planning.
A tenant improvement permit in Houston suburbs may take two to four weeks. The same tenant improvement in Los Angeles may take eight to sixteen weeks. Ground-up commercial construction takes longer than interior renovations in every jurisdiction, but the multiplier varies.
Large-scale projects requiring structural, mechanical, electrical, and plumbing review across separate departments face compounding review cycles. These parallel reviews can extend timelines well beyond initial estimates.
Projects that trigger discretionary review, such as those requiring zoning variances, conditional use permits, or design review board approvals, add an additional layer of unpredictability. These reviews often involve public hearings and elected or appointed decision-makers whose schedules and priorities are outside the applicant’s control.
In jurisdictions that require environmental review under the California Environmental Quality Act (CEQA) or the State Environmental Policy Act (SEPA), entitlement alone can add months to the timeline. Building permit review does not begin until entitlement is resolved.
Projects in coastal California and parts of the Pacific Northwest should plan for entitlement durations that may exceed the building permit review itself.
Even in jurisdictions without formal environmental review, zoning confirmation and use-specific approvals can introduce delays that project teams often underestimate. A project that appears to be by-right may still require fire department review, health department sign-off, or utility coordination that extends the critical path.
Effective due diligence before submission is the most reliable way to reduce permit timeline risk. The goal is not to eliminate uncertainty; it is to narrow the range of possible outcomes so that your schedule accounts for realistic timelines rather than theoretical best cases.
Most building departments publish estimated review timelines, but those estimates reflect ideal conditions. Published timelines typically describe the duration for a single review round of a complete, code-compliant submittal.
In practice, the gap between published and actual commercial project timelines can be two to five times the published figure. Project complexity and department workload drive that gap.
Start with the published timelines, then adjust for current conditions. Check whether the department has posted any advisories about backlogs or staffing changes. Look at recent project data if available.
At Burnham Nationwide, we maintain a project database with permitting timelines across hundreds of jurisdictions. This data allows us to provide more accurate forecasting than published estimates alone.
A common source of delay is discovering mid-process that additional approvals are required. Many jurisdictions require separate reviews from fire, health, environmental, and accessibility departments. These reviews may run sequentially rather than in parallel.
In some cities, a project cannot proceed to building permit review until zoning and site plan approvals are complete.
Map every required approval before you submit. Identify which reviews can run concurrently and which are sequential dependencies. This approval map becomes the foundation of a realistic permit schedule.
Burnham Nationwide’s code consulting services include this jurisdictional analysis as a standard part of project onboarding. This helps teams avoid discovering unknown requirements after submission.
Incomplete or non-conforming submittals are the most common and most preventable cause of permit delays. If a permit application is not approved on the first review due to missing documentation, it can set the approval process back several weeks or sometimes months.
Each resubmittal typically resets the review queue, meaning the project goes to the back of the line.
A thorough pre-submission review of plans and documents against the jurisdiction’s specific requirements reduces the likelihood of resubmittal. This includes confirming that drawings meet the local department’s format and content requirements and that all supplemental documents are included.
Burnham Nationwide’s permit expediting team reviews every submittal package against jurisdiction-specific checklists before filing. This pre-submission quality check reduces corrections and protects review timelines.
Even with thorough due diligence, certain delay triggers are common enough that project teams should plan for them explicitly.
Plan review comments are a normal part of the permitting process. The issue is that each comment-and-response cycle adds time. In jurisdictions where logged-in permit reviews take two to four weeks per round, a single resubmittal can add a month or more to the timeline.
Two or three rounds of comments can push a project months beyond its original schedule.
The most effective mitigation is accurate, complete documentation on the initial submission. Beyond that, rapid response to reviewer comments reduces the duration of each cycle. Having a local point of contact who can communicate directly with the plan reviewer, clarify questions, and coordinate corrections with the design team compresses these cycles significantly.
Building departments across the country continue to face staffing challenges. Demand for permitting services has remained elevated, but many departments have not restored the staffing levels needed to process applications within their published timelines. The result is backlogs that extend review durations beyond what project teams expect.
This is a risk factor largely outside the applicant’s control, but it is not invisible. Departments often post advisories when backlogs develop. Permit expediters with local relationships can provide current intelligence on actual review durations.
At Burnham Nationwide, our local project managers track department conditions in their markets. They provide clients with up-to-date timeline estimates that account for current staffing and workload realities.
Building codes are not applied uniformly across the country. Even jurisdictions that have adopted the same base code, such as the International Building Code (IBC), often apply local amendments and enforcement practices that differ significantly from neighboring cities.
A design that is fully compliant in one jurisdiction may trigger plan review comments in another because of a different local interpretation of the same code section.
For multi-jurisdictional projects, this means that a single set of construction documents may need to be adapted for each location. An early code analysis by someone familiar with the target jurisdiction’s specific requirements can identify these differences before they become resubmittal triggers.
When your project portfolio spans multiple cities and states, permit timeline risk management becomes a program-level discipline, not a project-by-project task.
A one-size-fits-all permitting schedule does not work for multi-jurisdictional projects. Each location needs its own timeline forecast based on the jurisdiction’s review process, current conditions, project type, and entitlement status. The aggregate of those individual forecasts becomes your program timeline.
This sounds resource-intensive, and it is. But the alternative, applying a single average timeline to every location, guarantees that some projects will be significantly delayed while others will have unnecessarily long buffers. Jurisdiction-specific forecasting allocates schedule contingency where it is actually needed.
Phased permitting allows construction to begin on approved portions of a project while later phases are still under review. For large commercial projects, this can compress overall project timelines by weeks or months. Foundation and structural permits may be issued while interior and mechanical plans are still in review, allowing site preparation and structural work to proceed.
Concurrent plan review, where multiple departments review different disciplines simultaneously rather than sequentially, offers a similar benefit. Not all jurisdictions support concurrent review, but where available, it can reduce total review duration by 30% to 50%. Knowing which jurisdictions offer these options, and structuring your submittal to take advantage of them, requires local expertise.
On multi-site programs, the volume of permits, comment letters, resubmittals, and deadline tracking can overwhelm even experienced project management teams. A centralized system that provides real-time visibility into the status of every permit across your portfolio reduces the risk of missed deadlines and lost communications.
This system should track the current status of each permit, projected timeline to issuance, outstanding comments, and responsible parties for each open item.
When a delay develops at one site, early visibility allows the program team to adjust schedules, reallocate resources, or escalate issues before they cascade into downstream construction delays.
The difference between a permit expediter who knows a jurisdiction and one who does not is measurable in weeks of review time. Local knowledge includes understanding which submission method matches your project scale, which departments review in parallel versus in series, and when to request a pre-submission meeting.
Burnham Nationwide operates with local project managers in markets nationwide. That model provides jurisdictional intelligence that digital-only permitting tools cannot replicate.
Our teams track how a specific building department is actually operating, which reviewers are handling which project types, and what the real turnaround times are this month.
Permit timeline risk does not exist in isolation. It affects construction schedules, financing, tenant commitments, and opening dates. How you communicate that risk to clients and stakeholders determines whether delays are managed or whether they become project crises.
A single-number permit timeline estimate creates a false sense of certainty. Instead, present permit timelines as ranges that reflect the jurisdiction’s typical review duration, the complexity of your specific project, and current department conditions.
A range of “12 to 20 weeks for plan review, with potential for additional review cycles” gives clients realistic expectations. It also reduces the risk of blame when timelines land at the longer end.
Provide context for the range. Explain what factors push timelines toward the shorter or longer end, and which of those factors are within the project team’s control. This transparency builds trust and helps clients make informed decisions about sequencing, financing, and contingency planning.
Clients should hear about potential delays from their project team before they discover them on their own. Regular status updates that include current review stage, estimated time to next milestone, and any emerging risks keep stakeholders informed and reduce the escalation that comes from unexpected bad news.
Burnham Nationwide provides project teams with regular updates and corrective measures throughout the review process, ensuring that clients have current information to make schedule decisions. This proactive communication is a core part of how we manage permit risk, not an add-on service.
Permit delays sometimes trigger contractual disputes about responsibility, schedule extensions, and cost impacts. Maintaining a clear record of submission dates, reviewer comments, response times, and resubmittal dates creates the documentation needed to resolve these disputes fairly.
The AIA A201 General Conditions framework addresses construction delays through provisions for extensions of contract time. Accurate permit timeline documentation supports those provisions.
A well-maintained permit timeline record also helps project teams identify patterns across their portfolio. If the same delay type recurs across multiple jurisdictions, it may point to a systemic submittal issue that can be corrected for future projects.
Despite thorough planning, some projects will face permit delays that exceed the schedule contingency you built in. When that happens, the response needs to be immediate and structured.
When a permit delay threatens the construction schedule, start by reassessing the critical path. Determine which construction activities are directly dependent on the delayed permit and which can proceed independently. In some cases, phased permitting or partial approvals may allow limited construction activity to continue while the full permit is resolved.
Explore whether the jurisdiction offers any expedited review options. Some departments allow applicants to pay for expedited review under certain conditions. Others offer over-the-counter review for specific project types or scopes.
Burnham Nationwide’s Chicago office, for example, has extensive experience navigating the city’s various review paths and can often identify faster alternatives when standard timelines are not workable.
A permit delay does not have to be a construction delay if the project team responds quickly. Coordinate with the general contractor to resequence work that does not depend on the delayed permit. Communicate with the client about revised milestone dates and any cost implications. Notify the design team if reviewer comments require plan revisions so that resubmittals are prepared before the jurisdiction requests them.
The key is speed. Every day between receiving a comment letter and submitting a response is a day added to the overall timeline. Teams that pre-position their response process and have direct communication channels with the reviewing department recover faster than those that treat comment responses as a routine task.
Permit timeline risk is not an abstract planning concern. It is a concrete, measurable factor that affects construction schedules, project costs, and client relationships on every complex commercial project.
The jurisdictions, codes, and staffing conditions that drive permit timelines will continue to vary. The project teams that manage that variance proactively will outperform those that treat permitting as an afterthought.
The foundation of effective permit timeline risk management is straightforward: research each jurisdiction before you submit, prepare complete and code-compliant documentation, track every open item, and communicate honestly with clients about what to expect.
At Burnham Nationwide, we have spent over 30 years building the local expertise, process discipline, and jurisdictional relationships that make this approach scalable across complex, multi-site portfolios. Contact Burnham Nationwide to discuss how we can help your next project stay on schedule.
Permit timeline risk is the possibility that building permit approvals take longer than your project schedule allows. This risk varies by jurisdiction, project complexity, and the completeness of your submittal. Managing it requires upfront due diligence and ongoing monitoring of review progress.
Burnham Nationwide reduces permit delays through jurisdiction-specific due diligence, pre-submission document review, and local project managers who track review conditions and communicate directly with plan reviewers. This approach catches issues before they become resubmittals.
Permit timelines differ because each jurisdiction sets its own review process, staffing levels, and code amendments. A project that permits in four weeks in one city may take four months in another due to different department structures, environmental requirements, and workload conditions.
Incomplete or non-conforming initial submittals are the most common preventable cause of permit delays. Burnham Nationwide’s pre-submission review process checks every document against jurisdiction-specific requirements, reducing the likelihood of corrections that reset the review queue.
Phased permitting allows approved portions of a project to begin construction while later phases are still under review. Burnham Nationwide uses phased and concurrent permitting strategies to compress overall timelines on large commercial projects, helping keep construction moving forward.
Present permit timelines as ranges rather than fixed dates, and provide regular status updates that include the current review stage, estimated time to the next milestone, and any emerging risks. Proactive communication builds trust and gives clients time to adjust schedules and budgets accordingly.
