Encroachment Permits

Any connection to a county-maintained road is considered an encroachment. If your building permit involves the construction of a new driveway or improvement to an existing one, or the connection to utilities under the road, it will require an encroachment permit.

Encroachment Permit Application

The County Department of Public Works has several different standard driveways. We will determine by inspection, the type of driveway that best fits your driveway approach. This determination takes into consideration the flow of storm drainage and other factors. When your building permit is issued, you will also receive an encroachment permit.

The current estimated fee for the issuing of an encroachment permit is (see fee schedule), payable to the County Public Works Department. The fee must be paid to issuance of your building permit.

You can determine if the county will be looking into the encroachment of your building permit by determining if you have a connection to a county-maintained road. Simply enter the road name that the building permit has access to. Keep in mind that this is only a cursory search, there are county roads that are not entirely county maintained. After the Development Services Division receives your building permit application, we will make the final determination.


County Road Listing

These are the roads, or portions of roads, maintained by the county. If your road appears in the list it is likely to be subject to an encroachment fee.
