Members of the Baltimore City Council voted Tuesday to advance a proposal that would set a new, higher property tax rate on vacant and abandoned houses, a first step toward cementing the bill into law. If passed by the rest of the council, the special tax rate could take effect as early as July 2026, bill co-sponsors Odette Ramos and Eric Costello said at a Tuesday committee hearing in City Hall. The bill received unanimous co-sponsorship by every member of the council when it was introduced earlier this month, a rarity relative to most pieces of legislation that move through City Hall.
