Other Information

Code Enforcement

A significant amount of time is spent following up on construction permits that have been issued, where, in most cases, the authorized work has been completed, but the required inspections have not been requested.

All improvements, with few exceptions, are subject to increased assessment regardless of whether or not a permit has been issued or inspections performed. The sole purpose of permits and inspections is for public safety and welfare. Please request a final inspection by contacting our office upon the completion of the work allowed by the construction permit.
