Whether you face mandatory water restrictions in New Jersey depends on your water utility, not just the statewide status. New Jersey is under a statewide NJDEP Drought Warning, which is voluntary. But several utilities have imposed their OWN mandatory restrictions on top of it: New Jersey American Water requires mandatory outdoor conservation for customers in Monmouth and Ocean counties; the Park Ridge Water Department has mandatory restrictions for Park Ridge and Woodcliff Lake through September 1, 2026; and Madison has borough-wide mandatory odd/even watering. Check your own utility below before assuming your rules are voluntary.
New Jersey has been under a statewide Drought Warning since December 5, 2025, declared by the New Jersey Department of Environmental Protection (NJDEP). As of July 7, 2026, about 75 percent of the state is in drought (roughly 42 percent severe and 9 percent extreme, US Drought Monitor). The Drought Warning is the third of four NJDEP tiers (Normal, Watch, Warning, Emergency); at the STATE level it is voluntary, so NJDEP asks every household to hold lawn watering to no more than two days per week and there are no state fines. Individual utilities, however, can and do make their own restrictions mandatory and enforceable within their service areas.
The drought is severe and long-running. New Jersey has recorded below-normal precipitation in 20 of the last 24 months and came through its driest 365-day period in roughly twenty years. State Geologist Steven Domber has described it as a chronic water supply drought, the scale of which the state has not seen in more than twenty years. NJDEP reported the drought area expanding again in May 2026.
Select your city below for the local utility, water source, NJDEP drought region, and city-specific conservation guidance. Hand watering with a shut-off nozzle and drip irrigation are unrestricted statewide. Only the Governor can escalate from a Drought Warning to a mandatory Drought Emergency.
How New Jersey Manages Drought
New Jersey's drought status is set by NJDEP, not by individual utilities. The NJDEP four-tier system is the governing state designation: Normal, Drought Watch, Drought Warning, and Drought Emergency. The state has been at Drought Warning since December 5, 2025. Under the Governor Mikie Sherrill administration, NJDEP Acting Commissioner Ed Potosnak has led the statewide voluntary conservation appeal.
Utilities also set their own rules, and those rules can be mandatory and enforceable within a utility's service area without waiting for a state Drought Emergency. As of July 2026, at least three New Jersey utilities have mandatory outdoor restrictions in force: New Jersey American Water requires customers in Monmouth and Ocean counties to stop non-essential outdoor water use and to water no more than twice per week, projected through at least September 1, 2026 (njamwater.com); the Park Ridge Water Department, which serves Park Ridge and Woodcliff Lake, has mandatory restrictions through September 1, 2026 (Park Ridge sprinklers Monday, Wednesday and Friday; Woodcliff Lake Tuesday, Thursday and Saturday), and as of July 2, 2026 prohibited all automatic sprinkler and irrigation systems until further notice except as authorized, after wells were taken offline for treatment work (parkridgeboro.com); and Madison has borough-wide mandatory restrictions with odd-numbered addresses watering on odd dates, even on even, sprinklers permitted only 7 a.m. to 6 p.m. (rosenet.org). Statewide, only the Governor can escalate the NJDEP tier to a mandatory Drought Emergency, but that is separate from these utility-level mandates, which are already in effect.
New Jersey last declared a statewide drought emergency from March 2002 to January 2003. The state's water supply draws on the Delaware River, the Passaic River, a network of North Jersey reservoirs, and the Coastal Plain groundwater aquifers of the south, so conditions and the right conservation response vary by region.
The NJDEP Four-Tier Framework and New Jersey's Six Drought Regions
NJDEP escalates drought response through four tiers. Normal: no action. Drought Watch: voluntary conservation requested. Drought Warning (current): stronger voluntary conservation, including a recommended two-day-per-week lawn-watering limit, with NJDEP able to direct water-supply transfers between systems. Drought Emergency: declared by the Governor, with mandatory restrictions, enforcement, and fines. New Jersey has been at the Drought Warning tier since December 5, 2025.
NJDEP tracks conditions across six drought regions, and a city's region determines which reservoirs, rivers, and aquifers drive its local outlook. Northeast: Bergen, Essex, Hudson, Passaic, Union. Central: Mercer, Middlesex, Monmouth, Somerset. Northwest: Sussex, Warren, Morris, Hunterdon. Southwest: Camden, Gloucester, Salem, Burlington. Coastal North: Ocean, with parts of Monmouth. Coastal South: Atlantic, Cape May, Cumberland. The Coastal South region entered a drought warning in fall 2024, ahead of the rest of the state.
New Jersey Lawn Grass and the 2026 Drought
New Jersey lawns are predominantly cool-season grasses, mostly established Tall Fescue and Kentucky Bluegrass. These grasses handle a voluntary two-day-per-week schedule well when watered deeply rather than shallowly.
Accept natural summer dormancy. Cool-season grass turns tan in heat and drought, but the crowns stay alive and the lawn greens up again with cooler, wetter weather; dormancy is survival, not death.
The single adjustment most New Jersey homeowners need to make is accepting a longer summer lawn. Fescue and Bluegrass maintained at 90 to 100mm summer height shade the soil and have substantially lower water demand than closely-cut lawns. Consider native plant conversion for parkway strips and low-traffic landscape areas to cut long-term water use.
Drought-Survival Watering by Grass Type
| Grass | Survival Watering | Mowing Height | Notes |
|---|---|---|---|
| Tall Fescue | 0.75 in/week deep | 3.5 inches | Most drought-tolerant cool-season; accepts dormancy |
| Kentucky Bluegrass | 1 in/week deep | 3.5 inches | Recovers with fall rain after dormancy |
| Perennial Ryegrass | 1 in/week deep | 3 inches | Common in blends; water early morning to limit disease |
| Native Landscape | Rainfall + spot drip | N/A | Long-term conversion target for low-traffic areas |
HOA Protection During Drought
New Jersey condominium and homeowner associations operate under the New Jersey Condominium Act (N.J.S.A. 46:8B) and the Planned Real Estate Development Full Disclosure Act (PREDFDA), which make association documents subject to applicable law.
The current statewide status is a voluntary Drought Warning, so HOA landscape covenants are not yet legally superseded. Even so, an association should not pressure residents to over-water against NJDEP's voluntary two-day-per-week guidance, and boards are encouraged to adopt that guidance for common-area turf.
If the Governor escalates to a mandatory Drought Emergency, state restrictions would override conflicting HOA lawn-appearance enforcement. New Jersey homeowners with HOA disputes during active restrictions can file a complaint with the New Jersey Department of Community Affairs' Regulatory Affairs Division.
Watering Your Lawn During the New Jersey Drought Warning
New Jersey's dense suburban Tall Fescue and Kentucky Bluegrass lawns hold up well on the voluntary two-day-per-week schedule when watered deeply. Apply about 1 inch of water per week including rainfall, split across the two days. Water between 5 a.m. and 10 a.m.; New Jersey's humid summer overnights make evening watering a near-certainty of Brown Patch on Tall Fescue and Pythium Blight on Ryegrass-heavy lawns.
New Jersey soils range from Coastal Plain sandy loam in the south to Piedmont clay-loam in the central and northern counties. South Jersey's sandier soils benefit from splitting each watering into two shorter sessions so water does not drain below the root zone. North Jersey clay soils respond to cycle-and-soak: 10 minutes, a 30-minute pause, then 10 minutes. Raise mowing height to 90 to 100mm during summer to lower water demand.

Frequently Asked Questions
Is New Jersey in a drought in 2026?
Yes. NJDEP has had New Jersey under a statewide Drought Warning since December 5, 2025, the third of its four tiers. The state has seen below-normal precipitation in 20 of the last 24 months and its driest 365-day period in roughly twenty years.
Are New Jersey water restrictions mandatory?
It depends on your utility. At the STATE level a Drought Warning is voluntary, with no state fines, and it becomes a mandatory statewide emergency only if the Governor declares one. But your water utility can impose mandatory, enforceable restrictions on its own: as of July 2026 New Jersey American Water (Monmouth and Ocean counties), the Park Ridge Water Department (Park Ridge and Woodcliff Lake), and Madison all have mandatory outdoor restrictions. Check your utility's own notice, linked in the sections above.
What day can I water my lawn in New Jersey?
At the state level there is no mandatory assigned-day schedule; NJDEP recommends watering no more than two days per week, before 10 a.m. or after 6 p.m. But your utility may set a mandatory schedule: Madison runs odd/even by address with sprinklers only 7 a.m. to 6 p.m., Park Ridge limits sprinklers to Monday, Wednesday and Friday (Woodcliff Lake Tuesday, Thursday and Saturday), and New Jersey American Water caps Monmouth and Ocean customers at twice per week. Select your city below and check your utility's own notice.
Can my New Jersey HOA fine me for a brown lawn?
Under the current voluntary Drought Warning, HOA landscape covenants are not legally superseded, but a board should not pressure residents to over-water against NJDEP guidance. If the Governor declares a Drought Emergency, mandatory state restrictions would override conflicting HOA lawn-appearance enforcement.
Can I harvest rainwater in New Jersey?
Yes. Residential rooftop rainwater harvesting is permitted in New Jersey. Rain barrels and cisterns are a useful way to supplement irrigation and reduce demand on municipal supply during the Drought Warning.
