Pennsylvania permit review deadlines
How long does it take to get a building permit in Pennsylvania?
Pennsylvania's Uniform Construction Code sets clear clocks. A home permit must be granted or denied in 15 business days, or 5 when a licensed design professional certifies the plans.
If the official does not act, the home permit is deemed approved. Commercial permits get 30 business days, with no stated consequence for a miss.

The short answer
Under 34 Pa. Code 403.63, a building code official must grant or deny a residential permit application within 15 business days of filing. If a Pennsylvania-licensed design professional prepared the drawings and certifies that they meet the code, the deadline is 5 business days. If the official does not act in time, the application is deemed approved. Commercial permits fall under section 403.43, which gives the official 30 business days and does not say what happens if the deadline is missed.
By project type
Pennsylvania permit review deadlines.
Pennsylvania's deadlines come from the Uniform Construction Code regulations.
| Project type | Deadline | What to know |
|---|---|---|
| Residential permit | 15 business days | To grant or deny, in whole or in part, from the filing date. |
| Residential permit with certified plans | 5 business days | Plans prepared and certified by a Pennsylvania-licensed design professional. |
| Commercial permit | 30 business days | No deemed approval in the rule. A different deadline can be set for historic districts. |
For both kinds of permit, the official and the applicant can agree in writing to extend the deadline by a set number of days.
Step by step
How Pennsylvania's review clock works.
There is no separate completeness period in the rule.
The shorter deadline rewards plans certified by a licensed design professional.
The official may approve foundations or other parts early, and may allow deferred submittals with prior approval.
It must name the parts of the application that do not comply and cite the code provisions.
What this means for a review team
- A residential deadline that ends in deemed approval leaves no slack for a queue.
- Certified plans cut the window to 5 business days, so intake needs to spot them on day one.
- Written extensions are the only way to add time.
When the clock runs out
What happens when a Pennsylvania department misses the deadline.
If the official does not grant or deny within the deadline, the application is approved by rule.
The commercial rule sets the 30 business days and stops there.
Faster permit approvals start with more efficient plan review.

Common questions
Pennsylvania building permit deadlines, answered.
How long does it take to get a building permit in Pennsylvania?
A residential permit must be decided in 15 business days, or 5 with plans certified by a licensed design professional. A commercial permit must be decided in 30 business days.

How long is a Pennsylvania permit good for?
A residential permit becomes invalid if work does not begin within 180 days of issuance. It can be valid for no more than 5 years.
How do Pennsylvania building departments keep up with these deadlines?
Three habits show up in the departments that hit the clock. They check applications for missing items in the first few days. They let building, fire, planning, and engineering review the same plans at the same time. And they track the days left on every review, so a manager can step in before a deadline passes.
