Applying for a Permit
Depending on the project, you may need to provide:
- Property information
- Description of the work
- Construction plans
- Site or plot plan
- Contractor information
- Estimated project value
- Additional approvals
More complicated projects may require plan review before the permit can be issued.
Permit Fees
Permit fees vary depending on the type and size of the project.
Rather than relying on an old fee amount, check the Building Department’s current information or contact the office before applying.
Inspections After the Permit
Getting the permit isn’t the final step.
Many projects require inspections at different stages of construction, such as foundation, framing, electrical, plumbing or final inspections.
Allen County Building Inspections
Don’t cover work that requires inspection until the appropriate inspection has been completed.
Doing the Work Yourself
Homeowners may be able to obtain permits for certain work on their own property, but permit and inspection requirements still apply.
For specialized electrical, plumbing or HVAC work, check with the Building Department about licensing or contractor requirements before beginning.
Already Started Without a Permit?
If you discover that work was started without a required permit, contact the Building Department.
Don’t continue the project and hope it won’t matter. The county can explain what needs to be done to bring the project into compliance.
Local Tip
If you’re unsure whether your project needs a permit, call before starting.
Describe exactly what you’re building or changing. A five-minute question beforehand can prevent delays, additional costs or having to redo work later.
