4. a. If the department proceeds to execute a notice or order issued
by it or by the court for the removal of a nuisance, the department may
let contracts therefor, in accordance with the provisions of any local
laws, ordinances, rules and regulations of the municipality applicable
to the letting of contracts for municipal improvements. The cost of
executing such notice or order or orders whether or not carried out
pursuant to court order shall be met from any appropriation made
therefor, or if such appropriation has not been made or is insufficient,
from the proceeds of the sale of obligations pursuant to the local
finance law. The department shall keep a record of such notices and
orders together with the acts done and the items of cost incurred in
their execution.
b. The municipality shall have a lien upon the premises of the
dwelling for the cost of executing such notice or order or orders for
the removal of a nuisance and shall file a notice of such lien in the
office of the clerk where notices of mechanics' liens are filed; and all
proceedings with respect to such lien, its enforcement and discharge
shall be carried on in the same manner as proceedings with respect to
mechanics' liens under the lien law.
c. Notwithstanding the foregoing and in addition to any other remedy
available, the department may maintain an action against the owner to
recover the cost of executing such notice or order or orders.
