AOB fees are collected through the Department of Conservation and Development, Building Inspection Division at the issuance of the building permit. Fees are collected at the rate in effect at the time the building permit is issued.
AOB fee credits are granted when the preexisting use is replaced by a new use that generates more traffic. The applicant would receive credit for traffic generated by the preexisting use. A project that changes a single family home into a commercial/retail building, or modifies a light industrial building into a commercial/retail building are examples of projects that would receive fee credit.
AOB fee waivers are granted only when vehicle trips are not added to the road network as a result of the proposed development (e.g. replacing an existing single family home, with a new single family home).
