2026 Slowest Major Cities for Permit Approval
Which major permitting markets publish the longest commercial first-review pathways? This benchmark compares a verified sample of official agency timelines while keeping business-day targets, staged reviews, weekly averages and observed calendar-day performance separate.
Longest comparable published standard paths
Business-day or working-day records in the launch sample. Specialty/expedited lanes excluded.
Longer published review paths — not a national “worst cities” list.
The report is intentionally narrower than its headline. It uses official public information to identify the longest published first-review pathways within Alliance's current verified sample. It does not claim to measure every U.S. jurisdiction, applicant experience, total permit issuance time or approval probability.
First review ≠ permit issuance
A 25–30 day first review may still require one or more correction cycles, prerequisite approvals or applicant responses before issuance.
Metric types stay separate
Targets, observed averages, staged reviews and weekly estimates are displayed as published. Alliance does not convert unlike metrics just to create a cleaner ranking.
Project scope matters
Large commercial projects often have longer review windows than tenant improvements, minor scopes or qualifying expedited programs.
Longest published standard commercial review paths in the launch sample.
Primary ordering uses only business-day or working-day pathways that can be compared without unit conversion. Scottsdale's XLT path is shown as two published sequential stages rather than collapsed into a single agency-stated total.
| Rank | Jurisdiction | Published path | Metric type | Project scope | Interpretation |
|---|---|---|---|---|---|
| 1 | Jacksonville / Duval County, FL | 25–30 business days | Current expectation | First review of a building permit | Longest directly comparable published first-review window in this launch sample. |
| 2 | Scottsdale, AZ | 7 business days administrative + 20 business days substantive | Staged target | XLT commercial / multifamily, 50,000+ sq. ft., 4 stories | Published as separate stages; do not treat the combined 27 days as an agency-stated single review guarantee. |
| 3 | Austin, TX | 20 business days | Published target | New construction / remodels over 25,000 sq. ft. | Large-project lane; smaller new construction publishes shorter 7- and 10-day paths. |
| 4 | Tucson, AZ | 20 business days | Performance goal | Standard Lane commercial new building, addition/alteration and related permit types | Standard published lane; separate review paths may apply to other scopes. |
| 5 | Mesa, AZ | 18 working days | Set timeframe | Regular commercial plan review | Paid expedited and super-expedited options publish shorter 10- and 5-working-day reviews. |
Important long-duration records that should not be forced into the business-day ranking.
These official metrics are highly useful, but their units or definitions differ from the primary table.
Nashville / Davidson County, TN
Metro Nashville says average turnaround for most commercial construction, additions, renovations and site plans is 4–6 weeks after receiving the plans.
Metric: published average in weeks · not converted to business days.Phoenix, AZ
Phoenix's April 2026 report shows observed average initial commercial-building review of 37 calendar days for major and 38 calendar days for medium projects.
Metric: observed previous-month average in calendar days.Phoenix — Major Goal
The same report lists a 45-calendar-day goal for major commercial building plans over 50,000 sq. ft. and more than $5 million.
Goal and observed average are intentionally shown separately.Jacksonville — Site Development
Jacksonville Development Services states a goal of completing the first Site Development Plan review within 30 working days.
Different workflow from the building-permit first-review record above.The published review window is only one component of permit duration.
Prerequisite reviews
Some jurisdictions require zoning, concurrency, civil, flood, fire or other agency reviews before the building review begins. Jacksonville, for example, explains that prerequisite DSD and agency reviews may need to clear before Building Inspection review starts.
Correction cycles
A first review can return comments. Applicant response time, design-team revisions and resubmittal review can materially extend the total calendar duration.
Large-project review bands
Austin and Scottsdale both publish longer windows for larger or more complex commercial projects than for smaller qualifying scopes.
Workload and complexity
Agencies may explicitly state that published averages fluctuate with submission volume and project complexity. A reported average should never be interpreted as a promise.
How Alliance builds the Slowest Cities benchmark.
This report uses the same source-first philosophy that supports Alliance's permit guides and the broader Permit Intelligence program.
Included in the primary ranking
- Official jurisdiction source.
- Commercial building or closely comparable commercial plan review.
- Published business-day or working-day standard pathway.
- Current enough to be verified as of September 4, 2026.
- No paid expedited lane used as the standard benchmark.
Kept outside the primary ranking
- Calendar-day averages mixed with business-day targets.
- Weekly averages that would require conversion assumptions.
- Total permit-issuance claims without a standardized definition.
- Specialty, express or qualification-based fast-track programs.
- Jurisdictions that do not publish a usable timing metric.
“Slowest” on this page means the longest published pathways within the current verified sample. It does not mean poor agency performance, low approval probability, or the longest actual permit duration in the United States.

Research MethodologySlowest permit-market benchmark FAQs.
Is this a ranking of the slowest permit departments in the United States?
No. This launch edition compares only jurisdictions in Alliance's verified sample that publish usable commercial first-review timing information. It should not be read as a census of every U.S. city.
Does first-review time equal total permit approval time?
No. First review is only one stage. Corrections, prerequisite approvals, fire review, zoning, civil review, fees, applicant response time and other dependencies can extend the full permit timeline.
Why are Phoenix and Nashville shown separately from the business-day ranking?
Phoenix publishes observed averages in calendar days and Nashville publishes an average in weeks. Those metrics are valuable, but converting them into business days would introduce assumptions, so they are shown as supplemental evidence.
Can Alliance guarantee a faster permit approval?
No. Alliance can research published requirements, organize application materials, submit where authorized, track review status, route comments and coordinate administrative responses, but approval decisions and review timing remain with the authorities having jurisdiction.
