Summary
Vallejo Municipal Code Section 7.62.045 bars any vacant lot from sitting idle for more than thirty days unless it is actively for sale, under active construction, or registered and actively kept free of blight through landscaping upkeep, trash and graffiti removal, and, if the city requires it, permanent fencing. The rule sits inside the city's Vacant Real Property ordinance and is enforced by the code enforcement division.

Violations & Fines

A vacant lot that draws three or more dumping, trespassing, camping or fire complaints in two years must be fenced under Section 7.62.055, and a broken or open fence left unrepaired more than seven days after notice is a separate violation.
