Summary

San Leandro requires every undeveloped lot to be fenced, signed, and kept free of weeds, debris, and stockpiled material at all times, with a local contact person on file so the City can reach someone about the property within 50 miles of it.

(a) The City Council finds that vacant lots that are undeveloped, poorly maintained, and open to the public can significantly and adversely affect the general welfare... Vacant lots overgrown with weeds and vegetation or accumulated with debris, trash, junk, discarded items, or other materials constitute a public nuisance... (c) Vacant lots must be maintained free of litter, weeds, dry brush, dead or dying vegetation, graffiti, debris, trash, junk, storage units, discarded items, and the stockpiling of any material at all times. (d) Vegetation Management: (1) Ground cover, turf, and grasses shall be maintained to be no more than four inches tall. (2) Weeds over four inches tall shall be removed. (e) Fencing and Security: (2) Vacant lots shall be fenced on all sides along, or within two feet of, the property line. (3) Fencing shall be a minimum of 72 inches in height.

Full Breakdown

SLMC § 3-1-220 imposes a standalone maintenance regime on top of the Community Preservation Ordinance's general nuisance rules for any lot that is undeveloped. The owner must designate a local contact representative with a working phone number and an address within 50 miles of the lot. The property itself must stay free of litter, weeds, dry brush, dead or dying vegetation, graffiti, debris, trash, junk, storage units, discarded items, and stockpiled material at all times, and the owner or designee must inspect it at reasonable intervals to confirm that.

Vegetation management standards cap ground cover, turf, and grasses at four inches tall and require weeds over four inches to be removed, with shrubs and hedges trimmed to leave at least 18 inches of clearance above the ground. Fencing and security rules require the lot to be fenced on all sides at or within two feet of the property line, with fencing at least 72 inches tall, non-view-obscuring, and fitted with a gate if the lot is 5,000 square feet or larger so emergency crews can get in.

Each frontage needs at least one posted 'No Trespassing' sign, plus a weather-resistant posting at least 18 by 24 inches giving the name, address, and 24-hour contact number of whoever maintains the property. The Community Development Director may approve an alternative method of securing a lot if it is at least as effective.

Violations & Fines

A vacant lot found in violation of § 3-1-220 is declared a public nuisance under § 3-1-225 and abated the same way as any Community Preservation Ordinance violation: a Code Enforcement Officer's notice of violation, a chance to appeal to the City Clerk within 15 calendar days, and City abatement billed to the owner if the condition isn't fixed. Repeat nuisance findings on the same lot within two years can draw treble abatement costs on top of the underlying fine.
