Frequently Asked Permit Questions

No – if it is a residential property, you are the owner and live on the property, then you can take out your own permits.

Permits are NOT required for fences. They can be placed up to the property line, although we do suggest that you keep a couple feet off the line for maintenance, and can be a maximum of six (6 ft.) feet in height.
