Taxes and Assessments
G.L.c. 143 , §9 permits a municipality, if the owner fails to do so, to demolish a property which is dangerous, unused, uninhabited or abandoned and provides for a lien in the favor of the municipality to secure the costs and expenses incurred in doing so. The obligation to pay the amounts due can be enforced by the municipality in an action of contract. The lien can be enforced as one under G.L.c. 139, §3A, which provides that the lien shall continue as a separate charge against the property for two years from October first next following the date of its filing and, thereafter, if it remains unpaid, it shall be added to the tax on the property (and thereby be secured by that lien).
