(1) In addition to the remedies now vested in boroughs to make repairs to sidewalks, any borough shall have power to make emergency repairs to any sidewalks within the borough if an inspection of the sidewalk discloses that, and a certificate made by the officer or head of the department or committee lawfully having charge of sidewalk repairs specifies that, a dangerous condition exists that can be repaired by an expenditure of not more than $1,000.

(2) Before repairs are made, a notice to make the repairs within 48 hours shall be served upon the owner of the property. If the owner cannot be served within the county, notice may be served upon the agent of the owner or the party in possession or, if there is no agent or party in possession, the notice may be served by posting the same upon the premises.

(1) Upon the completion of the work, the cost shall be a charge against the owner of the property and shall be a lien, until paid, upon the abutting property if a claim is filed. The charge may also be collected by action of assumpsit.

(2) This section is intended to provide an additional remedy for boroughs in connection with emergency repairs, where the actual cost of doing the work does not exceed $1,000. The certificate of the officer or head of the department or committee in charge of repairs to sidewalks shall be conclusive evidence of the existence of the emergency justifying the repair under the terms of this section.
