8 rules for unincorporated Bronx County, New York.
Verified from official government sources
NYC Admin Code 16-118 requires owners to keep lots free of weeds and rank growth. DSNY and HPD enforce. Practical threshold is around 10 inches of unchecked growth on vacant or neglected lots in the Bronx.
All street trees in The Bronx belong to NYC Parks Department. It is illegal for residents to prune, trim, or damage a street tree without a free Parks work permit. Even trimming branches over your sidewalk requires authorization.
Removal of any street tree in The Bronx requires a NYC Parks permit and is rarely granted. Private tree removal on residential lots generally does not require a permit unless the site is in a Special Natural Area District or Landmark zone.
Weed control falls under NYC Admin Code 16-118 (lot cleanliness) and DEC invasive-species rules 6 NYCRR Part 575. Owners must keep yards clear of rank weeds; sale or planting of DEC-listed invasives is prohibited statewide.
NYC draws water from the Catskill/Delaware and Croton reservoirs, so Bronx residents do not face the standing watering-day rules common in the West. NYC DEP activates drought-emergency restrictions only when reservoir levels trigger them.
Rainwater harvesting is legal in The Bronx. NYC DEP actively encourages residential rain barrels through free giveaway events. Stored water is for non-potable outdoor use only.
NYC supports native-plant landscaping. There are no turfgrass mandates in The Bronx, and the NYC Native Species Planting Guide is the standard reference for Parks and private projects.
Artificial turf is allowed on private property in The Bronx but must meet NYC DOB drainage, fire, and stormwater rules. NYC Parks has paused new crumb-rubber installations on parkland over health concerns. Lot-coverage and impervious-surface limits still apply.
