Full Breakdown
Union City Municipal Code § 7.08.060 obligates the owner of any parcel of land, whether improved or unimproved, to keep it free of earth, dirt, grass, weeds, dead trees, tin cans, rubbish, refuse and waste material that could endanger neighboring property or public health and safety. On a Fire Chief finding of noncompliance, the City posts and mails a notice to clean; if the owner fails to act within ten days, the Fire Chief removes the material and the removal costs become a special assessment collected on the property tax roll.
Violations & Fines
Failing to clean an unimproved or vacant lot after notice lets the City remove weeds and waste itself, billing costs as a lien on the property tax roll.
