Middlesex County sets no residential grass-height limit. In New Jersey, overgrown grass and weeds are a municipal property-maintenance matter, so each Middlesex town (New Brunswick, Edison, Woodbridge, Perth Amboy and others) enforces its own maximum lawn height, typically 8 to 12 inches, through its local code.
Trimming street and public-place trees in New Jersey is controlled by each municipality's Shade Tree Commission under N.J.S.A. 40:64, not by the county. Middlesex County only governs trimming of trees along county roads and inside county parks, handled by county Parks and Recreation.
Removing trees on private land in New Jersey is regulated by each municipality, which NJDEP now requires to adopt a tree-removal and replacement ordinance under the Tier A MS4 stormwater permit. Middlesex County controls only trees in county parks and along county roads.
NJDEP Tier A MS4 Stormwater Permit, Tree Removal/Replacement requirement (2022 Master Permit renewal)
By May 1, 2024, all municipalities with a Tier A MS4 Stormwater Permit are required to adopt and enforce an ordinance to control tree removal and replacement to reduce stormwater runoff and pollutants, and to promote infiltration of rainwater into the soil.
Middlesex County has no countywide weed ordinance for residential lots. In New Jersey, noxious weeds and overgrowth are a municipal nuisance matter, so each Middlesex town enforces weed removal on private property through its local property-maintenance code.
Middlesex County does not set lawn-watering schedules. Outdoor water use is governed by your water utility (Middlesex Water Company or NJ American Water) and by any statewide drought restriction NJDEP declares. Municipalities may add their own limits.
Rain barrels and residential rainwater harvesting are legal in New Jersey and Middlesex County imposes no ban. The state promotes rain barrels as a stormwater practice; only plumbing tie-ins to household water need code compliance, handled by your municipality.
Middlesex County does not require or ban native-plant landscaping on private property. New Jersey encourages native plantings and restricts certain invasive species, while any landscaping mandate would come from a municipality, not the county.
Middlesex County sets no countywide artificial-turf rule for homes. In New Jersey, whether synthetic turf is allowed, and any lot-coverage or stormwater conditions, is decided by each municipality's zoning and stormwater ordinances, not the county.
Backyard composting is legal in Middlesex County and encouraged statewide. New Jersey mandates that leaves be source-separated and recycled, and yard-waste handling is coordinated through the county Solid Waste Management Plan and each town's collection program.
