Summary
San Leandro caps grass on improved property at 18 inches before it becomes subject to abatement, under an Administrative Code height standard adopted pursuant to the Weed Abatement chapter's ban on letting weeds, rubbish, or dangerous material accumulate on private property.
§ 3-2-205. PRIVATE PROPERTY AND PUBLIC RIGHT-OF-WAY. No owner of property within the City of San Leandro shall permit or allow grass over a height established by the City Manager in the Administrative Code, weeds, rubbish or any material dangerous or injurious to neighboring property or the health or welfare of the public to remain on such property. The City Manager may establish in the Administrative Code such height limitation for abatement of weeds as he or she deems necessary or desirable. § 11.4.110. IMPROVED PROPERTY. When grass on improved property reaches a height of 18 inches or more, it will be subject to abatement pursuant to the provisions of San Leandro Municipal Code, Chapter 3-2.

Full Breakdown
SLMC § 3-2-205 makes it unlawful for a property owner to allow grass over a height set by the City Manager, or weeds, rubbish, or other material dangerous to neighboring property or public welfare, to remain on the property, and it authorizes the City Manager to fix that height in the City's Administrative Code. 105, applies the same 18-inch trigger to weeds and grass on vacant lots. The Administrative Code chapter notes there are no other height or condition limitations that must be met before abatement can be required under Chapter 3-2 beyond that 18-inch mark.
A separate section, § 3-2-200, bars letting grass, weeds, or other vegetation obstruct the sidewalk or street abutting the property, regardless of height. Any property maintained in violation of the Weed Abatement chapter is declared a public nuisance under § 3-2-210 and abated the same way as other Code violations, with abatement costs collected as a lien under Chapter 1-12.
Violations & Fines
Grass or weeds over 18 inches on an improved lot, or vegetation obstructing the sidewalk, is enforced as a Weed Abatement violation under § 3-2-210. The City proceeds through Chapter 1-12: a notice of violation, an opportunity to abate, and City-performed abatement billed to the owner as a lien if the deadline passes, with infraction fines running $100 to $200 before repeat violations become a misdemeanor punishable by up to $1,000 and six months in jail.
