The Manager may order appropriate measures to render a derelict structure secure from entry. The securing of the structure shall be by methods calculated to render entry very difficult, including, but not limited to, the use of lag screws in the boarding of entry points, instead of nailing. In order to perform the function or duty authorized or required under this section, city representatives and their agents shall have the right at reasonable times to enter upon the property and render a derelict structure secure from entry. If consent to inspect or secure the property is refused, the City shall apply for an inspection warrant. The costs incurred by the city in boarding or securing a derelict structure may be assessed to the property owner and collected as costs of abatement under Medford Municipal Code 5.520.
