9 rules for unincorporated Prince William County, Virginia.
Verified from official government sources
Prince William County limits grass and weeds to 12 inches on residential and commercial lots of two acres or less. Taller growth violates the county's tall grass and weed ordinance. Agriculturally zoned parcels are exempt.
PWC Tall Grass and Weed Ordinance (VA Code 15.2-901)
On residential and commercial properties with two acres or less, grass and weeds of more than 12 inches in height are not permitted.
Prince William County sets no general rule for trimming healthy trees on private property. Owners are responsible for maintaining their own trees; disputes over limbs crossing a property line are handled under Virginia common law, not county code.
There is no county permit to remove a healthy tree from an established residential lot. But clear-cutting or removing vegetation inside a Chesapeake Bay Resource Protection Area buffer is prohibited, and trees preserved on an approved development plan cannot be taken down without county sign-off.
PWC Code Ch. 32, Art. V, Pt. 504 (Chesapeake Bay Preservation)
RPAs include the land area within 100 feet of a perennial stream bank or edge of wetlands adjacent to the perennial stream. In general, no development, land disturbance, or vegetation removal is allowed in an RPA.
Weeds over 12 inches tall are prohibited on developed residential and commercial lots of two acres or less. The rule is enforced by Neighborhood Services under Virginia Code 15.2-901, which lets the county cut overgrowth and lien the cost to the owner.
VA Code 15.2-901
The owners of occupied or vacant developed or undeveloped property therein ... shall cut the grass, weeds, and other foreign growth, including running bamboo ... on such property or any part thereof at such time or times as the governing body shall prescribe.
Prince William County sets no permanent lawn-watering schedule. Virginia is a riparian (not scheduled-irrigation) water state, so day-of-week limits appear only when Prince William Water or the region declares a drought watch or warning.
Rainwater harvesting is legal in Prince William County and, as a riparian state, Virginia places no ownership limit on captured rain. Rain barrels are unregulated; larger cisterns or systems plumbed for indoor use must meet the Virginia building code and county permitting.
Prince William County actively favors native trees and woodland conservation in its landscaping standards. Development landscape plans must preserve native woodlands where possible; residents may plant native species freely so long as growth stays under the 12-inch weed limit.
PWC DCSM Section 800 (Buffer Areas, Landscaping, and Tree Cover)
Woodland conservation, replanting and reforestation standards are also appropriate and essential to ensure that the County's native woodlands are preserved and replenished, as well as for maintaining and creating wildlife habitats.
Prince William County has no ordinance banning or specifically regulating residential artificial turf. Synthetic lawns are generally allowed, but they cannot count toward the tree-canopy or landscaping requirements imposed on development sites, and drainage/impervious rules still apply.
Backyard composting is allowed in Prince William County. There is no permit for a residential compost pile, but it must be kept so it does not create odor, attract vermin, or become a nuisance under the county's property-maintenance and nuisance provisions.
