Concord requires grass and weeds to be maintained at 4 inches or less as part of annual weed abatement enforced by ConFire. Overgrown vegetation is declared a public nuisance under California Health and Safety Code Β§14875 and Concord Municipal Code chapter 8.35.
Concord enforces vegetation height standards through two overlapping programs. ConFire conducts an annual weed abatement program under California Health and Safety Code Β§14875 and California Government Code Β§Β§39560-39588, which authorize municipalities to declare overgrown grass and weeds a public nuisance and abate them at the owner's expense. Properties typically receive notice in March or April requiring compliance by late spring (usually by May or June). Grass, weeds, and dry vegetation must be cut to 4 inches or less and maintained through the fire season (October 31). The Concord Municipal Code chapter 8.35 also addresses property maintenance nuisances, including overgrown vegetation that harbors vermin, obscures visibility, or encroaches on sidewalks and rights-of-way. Code Enforcement issues courtesy notices first, followed by administrative citations starting at $100 for first offenses, $200 for second, and $500 for subsequent violations within a 12-month period. If the owner does not comply after the final notice, the city or ConFire may contract the abatement work and place a lien on the property for the cost plus administrative fees (typically $200-$500 plus contractor costs).
