How Long Does a Commercial Building Permit Really Take in 2026?

Ask any city planning department how long a commercial building permit takes and you will get a number that bears almost no relationship to what your project will actually experience. The published target is an aspirational SLA, calculated against a clean first submittal, a single straightforward use, and a reviewer queue that does not exist in any major US metro in 2026. The real number, the one that matters to your construction loan and your delivery schedule, is two to four times longer.

This post unpacks the gap between published and actual commercial permit timelines across the jurisdictions Commun-ET operates in, the structural reasons the gap exists, and the specific levers that compress it. If you are sizing a pro-forma or pressure-testing a developer's schedule, this is the number you need to defend in the room.

What the published numbers actually mean

Most major US plan-review departments publish a target cycle time of 20 to 45 business days for a standard commercial permit. New York City DOB lists a 40-day target for new building applications under the standard plan-examination track. Los Angeles LADBS publishes 30 to 60 days for tenant improvements and 90 to 120 days for new commercial construction. Chicago DOB advertises a 30-day target for standard commercial. Austin DSD lists 21 days for commercial new construction at intake.

These numbers are reviewer-time only, measured from the moment a complete application reaches a plan examiner's desk to the moment that examiner returns a first round of comments. They do not include intake completeness review, the wait between submittal and examiner assignment, the cycles of corrections and resubmittals, the parallel reviews from other agencies (fire, health, transportation, environmental), or any of the time the package spends sitting on a customer's side waiting on the design team. In a real project, the published number is between 15 and 30 percent of the total elapsed time.

“The published cycle time is marketing. The real cycle time is the one your insurer, your lender, and your construction loan are pricing against.”

What the real numbers look like, by market

Across our 2025-2026 program data, the median elapsed time from first complete submittal to approved commercial building permit is 4.5 months for a typical 30,000-square-foot tenant improvement in a tier-1 metro, and 9 to 14 months for ground-up commercial construction. The variance by jurisdiction is the headline. The same project type lands at a 3.5-month median in Houston, a 6-month median in Los Angeles, an 8-month median in San Francisco, and can stretch past 12 months in jurisdictions with active building moratoria or unusual concurrent-review requirements.

We track these timelines per-market in our coverage directory, and our Los Angeles permitting guide, New York City permitting guide, Chicago permitting guide, Austin permitting guide, and Houston permitting guide break down what to expect in each. The pattern is consistent: jurisdictions with online plan-review portals and well-staffed examiner pools cluster tightly around their published targets. Jurisdictions with paper-based intake, examiner shortages, or politically active review boards run two to four times longer than advertised.

The five drivers of cycle-time variance

First, intake completeness. A submittal rejected at intake for missing exhibits or wrong-format drawings is not in the reviewer queue at all, and the clock does not start until it is. We see 30 to 50 percent of first submittals returned at intake in tier-1 metros. Each intake rejection costs one to three weeks before the package is back in line.

Second, concurrent-review coordination. A commercial permit is never a single review. Fire, public works, transportation, health, sanitation, and environmental all review in parallel or sequence depending on jurisdiction. A late hand-off between any two of them stalls the whole permit, and most published cycle times measure only the building department leg.

Third, response-to-comments turnaround on the applicant side. Plan examiners issue comments, the design team turns them around, and the package goes back into the queue. We see customer-side turnaround times ranging from 5 days to 45 days. The shorter that number, the faster the permit. This is the single largest lever the project team controls.

Fourth, reviewer continuity. If your file changes examiners mid-cycle, you will pay for it in a re-review that introduces fresh comments on conditions that were already negotiated. Jurisdictions with high examiner turnover (most major metros in 2025-2026) generate this risk continuously.

Fifth, jurisdictional backlog. Plan-review queues fluctuate seasonally and respond to local construction volume. A permit filed in February in most US metros will clear faster than the same permit filed in September, when the post-summer surge hits.

What compresses the cycle

The interventions that actually move the median are the unglamorous ones. A pre-application meeting with the building department before the first dollar is spent on construction documents will catch 60 to 80 percent of the conditions that would otherwise show up as first-round comments. Most jurisdictions offer these for free or for a nominal fee. Almost no one uses them.

A standardized submittal package built against the specific jurisdiction's format, drawing index, and response-to-comments template will cut intake rejection rates from 30 percent to under 10 percent. This is template work, not creative work, and it pays back every cycle.

A named relationship with the reviewer pool matters more than most operators are comfortable admitting. We are not talking about influence. We are talking about the difference between a permit examiner who picks up your file and recognizes the template versus one who treats it as a cold submittal. That relationship is what Commun-ET principals carry into every engagement.

Finally, parallel-tracking the non-building reviews. Most schedule slip in commercial permitting comes from sequential thinking about fire, transportation, and utility reviews that could have run alongside the building review with deliberate coordination. The Utility Coordination Field Guide goes deep on the utility-coordination piece.

How to use these numbers in a pro-forma

Stop using the published target. Use the jurisdiction's actual P75 elapsed time for your specific use type, plus a 20 percent contingency, plus the full duration of any concurrent permits (signage, encroachment, utility connection) that gate occupancy. For most tier-1 metros, that means budgeting 4 to 6 months for tenant improvements and 9 to 15 months for ground-up commercial. If your construction loan terms or your tenant's opening date cannot tolerate that, the permit strategy needs to start before the LOI is signed, not after.

Commun-ET maintains live P50/P75/P90 cycle-time data across every jurisdiction we operate in. If you need a defensible number for a specific permit type in a specific market, that is exactly the question our External Project Management engagement is built to answer in the first thirty days.
