Summary

Tacoma treats grass, weeds, or brush over one foot tall on any lot as a public nuisance the property owner must correct, with limited exceptions for erosion control or critical areas.

Overgrown, uncultivated, unkempt, or potentially hazardous vegetation of any type, including, but not limited to, shrubs, brush, trees, weeds, blackberry vines, and grasses over one foot in height or length that poses a threat to public health, safety and welfare, including vegetation which may harbor rodents or transient activity. Where erosion control issues, indigenous species, or critical areas as defined in TMC Chapter 13.11 are present, an exception or modification may be made to these requirements. Where a single parcel is undeveloped and over one acre in area, elimination of the fire hazard presented by vegetation may be accomplished by removing the vegetation from the area within 20 feet of abutting, improved properties or public rights-of-way.

3. Inappropriate disposal or accumulation of vegetation waste, including, but not limited to, grass clippings, cut brush, cut trees, cut weeds, and/or cut wood, except as contained in a compost pile not to exceed two cubic yards, or orderly stacked fire wood, if cut in lengths of four feet or less.

4. Any poisonous or hazardous material or thing on any real estate, so as to allow access to it by any animal or person.

5. Storing of flammable material on any real estate, including but not limited to old rags, rope, cordage, rubber, boxes, or paper, by properly licensed persons or businesses trading in such articles, unless it is in a building of fireproof construction.
