Connecticut permit review deadlines
How long does it take to get a building permit in Connecticut?
Connecticut has one of the oldest and simplest rules on the map. A local building official must issue or refuse a building permit within 30 days of the application.
The rule has no fee refund and no automatic approval. It sets the expectation and leaves enforcement to appeals and complaints.

The short answer
Under Connecticut General Statutes section 29-263, a building official must issue or refuse a building permit, in whole or in part, within 30 days of the date of application. The law does not approve a permit automatically when the 30 days pass, and it does not refund fees. An applicant's remedy for a late decision is an appeal or a complaint.
By project type
Connecticut permit review deadlines.
Connecticut sets a single statewide deadline for building permits.
| Project type | Deadline | What to know |
|---|---|---|
| Any building permit | 30 days | To issue or refuse the permit, in whole or in part. Counted from the date of application. |
State guidance says an application that is missing a required zoning permit should be denied in writing within the 30 days, with a note that it will be held open for six months.
Step by step
How Connecticut's review clock works.
There is no separate completeness period in the statute.
A partial approval or partial refusal counts.
State guidance tells officials to name what is missing, such as a zoning permit, so the applicant can fix it.
When the clock runs out
What happens when a Connecticut official misses the 30 days.
The statute does not refund fees or treat a late permit as approved.
A late or refused permit can be taken up through the state building code appeal process.
Faster permit approvals start with more efficient plan review.

Common questions
Connecticut building permit deadlines, answered.
How long does it take to get a building permit in Connecticut?
State law gives the building official 30 days from the date of application to issue or refuse the permit. Simple projects are often faster. The 30 days is the outer limit in the statute.
What happens if the 30 days pass with no decision?
The permit is not approved automatically and no fee is refunded. The applicant's options are an appeal or a complaint.
Does a missing zoning approval stop the clock?
Not according to state guidance. The building official should deny the application in writing within the 30 days and hold it open for six months while the applicant gets zoning approval.
How do Connecticut 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.
