Moderate Projects

Examples:

• home additions

• larger renovations

What Affects Permit Approval Time?

Several factors determine how long the process takes.

1. Completeness of the Plans

This is the biggest factor.

If your drawings are missing information or unclear, the county will issue comments.

Each round of revisions adds time.

If you’re not sure what a complete set should include, see what is included in a permit plan set.

2. Type of Project

Larger and more complex projects take longer to review.

• residential projects are usually faster

• commercial projects require more coordination

3. County Workload

Review times can vary depending on how busy the county is.

Some seasons have higher submission volumes, which can slow things down.

4. Zoning and Code Issues

If your project doesn’t meet zoning or code requirements, it will not be approved on the first review.

This leads to revisions and delays.

5. Number of Review Cycles

Each time plans are submitted, they go through a review cycle.

If issues are not fully resolved, the process repeats.

This is where timelines can extend significantly.

Why Some Permits Take Much Longer

Delays are usually not caused by the county alone.

They often come from:

• incomplete drawings

• missing structural details

• unclear scope of work

• inconsistent plans

If your drawings are not clear, the review process slows down.
