Allowed Watering Hours

Irrigate in the early morning or evening; avoid the midday heat to limit evaporation

The Florida Keys Aqueduct Authority maintains year-round landscape irrigation guidance for Monroe County, generally limiting lawn watering to about two days per week and to the cooler parts of the day. The South Florida Water Management District issued a water shortage warning for Miami-Dade and Monroe counties on February 5, 2026, and rescinded it on March 30, 2026, after March storms recharged the Biscayne Aquifer. Because FKAA periodically updates its schedule, confirm the current watering days and hours at fkaa.com before adjusting your irrigation system.

Still Allowed

💧 Hand Watering

Allowed with shut-off nozzle. Hours: Hand watering with a shut-off nozzle is allowed; FKAA still encourages watering outside the midday heat.

Fines & Enforcement

Enforced by Monroe County and municipal code enforcement; confirm current penalties with FKAA

Outdoor watering rules in the Keys are enforced through county and municipal code enforcement. Specific penalty amounts are not published in a single schedule; contact FKAA at 305-296-2454 to confirm current enforcement before assuming a figure.

🏠 HOA Rules During Restrictions

Florida law limits the ability of HOAs to penalize residents for following water restrictions or for installing Florida-Friendly landscaping. In the Keys, salt-tolerant and drought-tolerant plantings are both practical and protected.

If your homeowners association sends a violation notice for a dormant or brown lawn during the current restriction period, respond in writing citing the applicable law and include a copy of the current restriction order from Florida Keys Aqueduct Authority. Most HOAs will rescind the notice once they are made aware of the legal protections in place. If the issue persists, contact your county’s code enforcement division for assistance.

Why These Restrictions Exist

Key West and the rest of the Florida Keys are served by the Florida Keys Aqueduct Authority, a regional utility unlike any mainland Florida water provider. FKAA produces almost no fresh water locally. Roughly 90 percent of the Keys' drinking water is drawn from the Biscayne Aquifer at well fields in southern Miami-Dade County and piped about 130 miles down US-1 to the islands. Reverse-osmosis desalination plants at Stock Island, near Key West, and in Marathon provide emergency backup if the pipeline is disrupted.

That structure makes the Keys uniquely dependent on a single pipeline and on mainland groundwater. A hurricane strike, a main break, or a drought in southern Miami-Dade can all affect supply far from Key West itself. For that reason FKAA promotes year-round conservation rather than treating restrictions as a drought-only measure.

In early 2026 the South Florida Water Management District, whose jurisdiction includes Monroe County, issued a water shortage warning for Miami-Dade and Monroe counties on February 5. Heavy March rainfall recharged the Biscayne Aquifer, and the District rescinded the warning on March 30, 2026. South Florida remains in its dry season, so FKAA continues to ask Keys residents to use water efficiently year-round.

Rainfall Deficit: March 2026 storms recharged the Biscayne Aquifer that supplies the Keys; the South Florida Water Management District rescinded its Miami-Dade and Monroe water shortage warning on March 30, 2026.

This deficit has accumulated over the current water year and represents a significant departure from historical averages for the Key West area. Water supply reservoirs and aquifer levels are below seasonal targets, prompting regional voluntary conservation guidance.

How to Keep Your Lawn Alive During Key West Water Restrictions

9 tips tailored for Key West homeowners during Year-Round Conservation (FKAA); Drought Warning Rescinded March 2026 restrictions.

Key West gets almost all of its water through a single 130-mile pipeline from the mainland; year-round conservation is a resilience measure, not just a drought response.

Most Key West lawns are salt-tolerant warm-season grasses; water deeply and infrequently to build roots that handle the islands' heat and wind.

Irrigate in the early morning or evening; the Keys' strong sun and sea breeze evaporate a large share of any midday watering.

Confirm FKAA's current watering schedule at fkaa.com, since the authority updates its year-round irrigation guidance periodically.

Switch flower beds and container plants to drip irrigation, which uses far less water than spray heads in a windy coastal setting.

Choose Florida-Friendly and salt-tolerant plants suited to the Keys, which need little irrigation once established.

Capture rainwater from roofs during the wet season for hand watering; the Keys have no natural fresh surface water to fall back on.

Check for leaks regularly; a hidden leak in the Keys wastes water that traveled 130 miles by pipeline to reach your home.

Keep an eye on FKAA's alert center during hurricane season, when pipeline disruptions can shift the islands onto reverse-osmosis backup supply.

Key West Water Restriction FAQs

What hours can I run my sprinklers in Key West?
Under voluntary conservation, Key West has no mandatory hour restrictions. The utility recommends watering in the early morning or evening to reduce evaporation, but no citations apply under voluntary conservation.
What are the fines for water violations in Key West?
Outdoor watering rules in the Keys are enforced through county and municipal code enforcement. Specific penalty amounts are not published in a single schedule; contact FKAA at 305-296-2454 to confirm current enforcement before assuming a figure. The Florida Keys Aqueduct Authority (FKAA) and local Monroe County enforcement officers conduct patrols and respond to complaints. Keep your irrigation timer set to your assigned day and hours to avoid citations.

When will water restrictions end in Key West?
The current Year-Round Conservation (FKAA); Drought Warning Rescinded March 2026 conservation guidance in Key West is effective from Year-round FKAA conservation guidance through Ongoing; South Florida Water Management District warning rescinded March 30, 2026. However, the guidance may be extended if drought conditions persist or eased if significant rainfall improves water supply levels. Monitor the Florida Keys Aqueduct Authority (FKAA) website for updates.
Who supplies Key West's water?
The Florida Keys Aqueduct Authority (FKAA) is the sole potable water provider for Key West and all of Monroe County. FKAA is distinct from mainland Florida utilities and from the regional water management districts; it produces almost no fresh water locally and instead pipes water from the mainland.
Where does Key West's water actually come from?
About 90 percent of the Keys' drinking water is drawn from the Biscayne Aquifer at well fields in southern Miami-Dade County and piped roughly 130 miles down US-1 to the islands. Reverse-osmosis desalination plants at Stock Island near Key West and in Marathon serve as emergency backup if the pipeline is disrupted.
Are there mandatory watering restrictions in Key West right now?
FKAA maintains year-round landscape irrigation guidance rather than a drought-only restriction. The South Florida Water Management District issued a water shortage warning for Monroe County on February 5, 2026, and rescinded it on March 30, 2026, after March rains recharged the aquifer. Confirm the current watering schedule at fkaa.com.
Why does Key West push conservation even when there is no drought warning?
Because the Keys depend on a single 130-mile pipeline and on mainland groundwater, supply can be affected by hurricanes, main breaks, or drought far from Key West itself. FKAA treats conservation as a year-round resilience measure so the islands have a margin of safety if the pipeline is ever disrupted.
What happens if the mainland pipeline is cut off?
FKAA operates reverse-osmosis desalination plants at Stock Island, near Key West, and in Marathon as emergency backup. These plants can produce fresh water from seawater or brackish water during a pipeline outage, but their capacity is limited, which is another reason FKAA emphasizes everyday conservation.
