Summary

Anne Arundel County bans weeds or grass over 12 inches on most properties, but the Director of Public Works may modify that limit for natural wooded areas, covenanted open space, and plantings needed for soil stabilization or erosion control.

These county ordinances apply to unincorporated areas of Anne Arundel County. Incorporated cities within the county may have their own rules that take precedence over county-level regulations.

(b) Modification. The Director may modify the provisions of this section for agricultural property, natural wooded areas, areas publicly owned and maintained as natural areas, open space areas covenanted with the County as open space, open areas, or recreational areas, and areas where a growth of grass or weeds is necessary for soil stabilization and erosion control.

Full Breakdown

County Code § 13-6-103 prohibits an owner from allowing "rank vegetation" (weeds or grass 12 inches or higher) or noxious weeds on their property, and applies countywide except to open space zoning districts, most RA-zoned parcels, unimproved lots of three acres or more, and government or association-owned parcels. Subsection (b) lets the Director of Public Works modify the standard for agricultural property, natural wooded areas, publicly maintained natural areas, covenanted open space, and areas where grass or weed growth stabilizes soil or controls erosion: the route for a native or naturalized planting bed to stay compliant. Noxious weeds must be destroyed by cutting, removal, or plowing under, not chemical spraying, except in the Critical Area where the Department of Public Works must approve the removal method.

Violations & Fines

Complaint-driven: Public Works investigates and, if it finds a violation, serves 7-day written notice to cut, trim, remove, or destroy the growth; unresolved violations let the County do the work and bill the owner, collectible like unpaid taxes if unpaid after 30 days.

Frequently Asked Questions

Can I grow a native meadow or naturalized bed instead of mowed lawn in Anne Arundel County?
Yes, but it needs Director of Public Works sign-off under § 13-6-103(b) as a natural area, open space, or erosion-control planting: an unapproved 12-inch-plus stand is rank vegetation and can draw a violation notice.
Does this rule apply in Glen Burnie or Severna Park?
Yes. Both are unincorporated, so the County Code is their only local law and § 13-6-103 applies directly: there is no separate municipal ordinance to check.
What happens if I ignore a rank vegetation notice?
Public Works can cut or remove the growth itself after the 7-day notice period and bill the owner for the cost, including overhead, due within 30 days.
