Water Restrictions Explained: Stages, Rules & Compliance Guide
Published: July 8, 2026
Water restrictions limit when, how, and how much you can use water outdoors. They run from a voluntary advisory to an emergency-rationing order, and the specific rules vary by city, utility, and state. This guide walks through how the system works, what each stage means, how fines escalate, and how state HOA-protection laws shield homeowners from being penalised for following the rules.
What are water restrictions?
A water restriction is a rule issued by a water utility, regional water authority, or state environmental agency that constrains outdoor water use. The most visible form caps lawn irrigation to specific days of the week and specific hours of the day, but restrictions extend across vehicle washing, pool filling, pressure washing, decorative fountain operation, new sod installation, and commercial uses such as construction site dust suppression.
Restrictions exist on a spectrum from voluntary to mandatory. Voluntary advisories carry no fines and ask residents to cut outdoor use; mandatory orders are enforceable, with citations, escalating fines, and in extreme cases service shut-off. The international classification framework most utilities use traces back to the US Drought Monitor categories (D0 abnormally dry through D4 exceptional drought), with each utility setting its own quantitative triggers tied to those categories.
Authority to impose restrictions varies by jurisdiction. In Texas, the city water utility usually owns the schedule (San Antonio SAWS, Austin Water, City of Killeen), with regional input from the Brazos River Authority or Edwards Aquifer Authority. In North and South Carolina, the Catawba-Wateree Drought Management Advisory Group coordinates a Low Inflow Protocol across 24 counties, with each member utility enforcing locally. In Georgia, the state Environmental Protection Division (EPD) declares statewide Levels 1–4 that all public water systems follow. California devolves authority to the State Water Resources Control Board, which can override local utilities when the governor declares a drought emergency.
Why utilities issue water restrictions
Restrictions activate when one or more supply or demand triggers cross a threshold defined in the utility’s Drought Contingency Plan. The most common triggers are:
- Reservoir storage falling below seasonal target. Most plans set 70% as the Stage 1 trigger, 50% for Stage 2, and 30% for Stage 3.
- Snowpack below normal. Western utilities (Denver Water, JVWCD in Utah, SLC Public Utilities) tie spring triggers directly to April 1 snowpack measurements.
- Aquifer level. The Edwards Aquifer Authority uses the J-17 monitoring well in Bexar County: SAWS Stage 3 is triggered when J-17 falls below 640 ft and lifts only after 15 consecutive days above that threshold.
- US Drought Monitor classification. Cities tied to the federal monitor escalate stages when their county moves from D2 (severe) to D3 (extreme) to D4 (exceptional).
- Infrastructure capacity. Treatment-plant limits or transmission-main outages can trigger restrictions even when raw water supply is adequate. Metro Vancouver moved directly from no-stage to Stage 2 in May 2026 partly because the First Narrows Crossing supply main is offline for repair.
Real triggers in effect this season illustrate the variety. The Catawba-Wateree basin in North and South Carolina entered LIP Stage 2 mandatory on May 1, 2026 — its first Stage 2 since 2009 — after the driest October-to-March recharge season since records began in the 1970s, with Mecklenburg, Cabarrus, Stanly, and Union Counties at D4 exceptional drought (first D4 in the Charlotte region since 2008). Salt Lake Valley snowpack measured 8.4 inches on April 1 against a 14-inch normal, prompting Salt Lake City Stage 2 in March 2026. Edwards Aquifer J-17 sat at 625.9 feet in April 2026, well below the 640-ft Stage 3 exit and approaching the 630-ft Stage 4 trigger. Georgia EPD moved 53 counties to Level 1 on April 27, 2026.
The four-stage system explained
Most US utilities organise their plans into four stages progressing from mild to critical. The labels and exact rules vary, but the structure is consistent enough that the shape of the response is predictable across cities.
Stage 1 — Mild / Voluntary or Light Mandatory
Stage 1 is the entry-level response: outdoor watering is capped at roughly three days per week, with no irrigation between about 10 a.m. and 6 p.m. Most utilities designate it as voluntary, though a handful (Denver Water, Long Beach) start at mandatory Stage 1. Fines, where they exist, range from $0 to $200 for first offences. Vehicle washing at home with a shut-off nozzle, pool filling, and new sod installation (with variance) all remain permitted.
Stage 2 — Moderate / Mandatory
Stage 2 brings firm mandatory rules. Outdoor watering drops to two days per week with strict enforcement of the 10 a.m. to 6 p.m. blackout. Fines start at $100 and reach $500 for repeat offences. Vehicle washing at home is typically prohibited (commercial recycling-equipped car washes remain open). Pool top-offs are usually permitted but new fills require variance. Stage 2 is the most common active stage in the US right now — Charlotte Water, NTMWD member cities in Texas, Salt Lake Valley utilities, and 24 Catawba-Wateree counties are all currently at Stage 2.
Stage 3 — Severe / Strict Mandatory
Stage 3 cuts allowed outdoor watering to one day per week, often shifted to overnight-only windows. Fines start at $250 and run to $2,000 for repeat or commercial violators. Vehicle washing at home is banned outright. Pool fills are banned unless a variance is granted (typically only for newly built homes). New sod and seed installations are banned. San Antonio (SAWS) has been continuously at Stage 3 since June 2024 — the first Stage 3 in its 30-year history. Eagle and Vail Colorado, Kerrville and Seguin Texas, and several Utah cities are also at Stage 3.
Stage 4 — Critical / Emergency
Stage 4 is the emergency tier. Outdoor irrigation is restricted to once every 14 days or banned outright, often with brief overnight windows. Fines start at $500 and routinely exceed $2,000 for repeat violators, with service shut-off available as a tool. The South-Central Texas Lower Guadalupe Cooperative (SSLGC), serving Schertz and Cibolo, runs Stage 4 at once-every-14-days — the most restrictive residential outdoor watering schedule currently in force in Texas. Boerne and Riverdale UT are also at Stage 4.
Stage, Phase, and Level — same idea, different names
Common rules across all stages
Most utilities enforce a baseline of year-round permanent rules that apply regardless of drought stage. Even when no stage is declared, these rules are typically in effect:
- No watering during or within 48 hours of measurable rainfall. Even unrestricted utilities prohibit running sprinklers right after a storm.
- No watering between 10 a.m. and 6 p.m. (or 10 a.m. to 4 p.m. in Georgia EPD-regulated systems). The midday blackout reflects evapotranspiration losses of 30 to 40 percent during peak heat.
- No washing impervious surfaces. Driveways, sidewalks, and patios cannot be hosed clean — sweep instead.
- Decorative fountains must recirculate water. Single-pass fountains are banned in nearly all utility districts, drought stage or not.
- Restaurants serve water on request only. A Texas-wide rule going back to the 2011 drought of record; California, Colorado, and several other Western states have the same rule.
- Hand watering with a shut-off nozzle is almost always exempt from the day-of-week schedule (though midday blackouts still apply). Drip irrigation, soaker hoses, and foundation watering follow the same exemption pattern.

How to find your local watering schedule
Don’t guess. Five reliable ways to confirm what stage your address is on and which days you can water:
- Check your utility’s website.Almost every US water utility publishes a current drought page (look for “water conservation”, “drought status”, or “watering schedule” in the menu).
- Call your utility directly.Numbers are on your monthly bill or under the city’s “contact us” page.
- Use the LawnBySeason directory. Visit the water restrictions hub to find your city’s current stage, watering days, and fines.
- State agency websites. Georgia (epd.georgia.gov), Florida (floridadep.gov), Texas (tceq.texas.gov), and California (water.ca.gov) all publish statewide drought status maps.
- Sign up for utility alerts. Most utilities offer text or email notifications when a stage activates, changes, or lifts.

Fines and enforcement
Enforcement structure is consistent across the US even when fine amounts vary. Most utilities follow a graduated escalation:
- Warning on first observation (some utilities, including SWFWMD in Florida, eliminated this step in 2026 — see their notice).
- $100 to $500 for second offence in Stage 1 or 2.
- $500 to $2,000 for third or repeat offence in Stage 2 or higher.
- Service shut-off for repeated egregious violations (rare but available).
- Property liensin some jurisdictions for unpaid drought fines that exceed the city’s administrative threshold.
Enforcement methods range from passive to active: 311 / 511 water-waste hotlines (most cities), neighbour reporting, code-enforcement officer patrols, smart-meter spike alerts (any utility on AMI metering — increasingly common), and in advanced districts satellite-based wet-area detection. AMI smart-meter data lets utilities flag off-schedule irrigation automatically, then dispatch officers for field verification, which is how Cedar Park, Pflugerville, and several other Texas cities run enforcement.
HOA brown-lawn protections by state
HOAs cannot lawfully fine homeowners for brown or dormant lawns caused by complying with mandatory water restrictions in most US states with active drought protection laws. The relevant statutes:
| State | Statute | What it protects |
|---|---|---|
| Texas | Property Code §202.007 | Brown lawns during drought, drought-tolerant xeriscaping |
| Colorado | HB 21-1229 | Water-wise landscaping, conversion of turf to drought-tolerant species |
| California | Civil Code §4735 | Drought-compliant lawns, low-water plantings |
| Utah | SB 152 (2022) | Water-wise landscaping protections |
| Georgia | OCGA 44-3-235 | HOA rules cannot conflict with state-level water emergency orders |
| Florida | Statute 720.3075 | Florida-friendly landscaping, brown lawns during WMD orders |
| Nevada | NRS 116.31085 | Drought-tolerant landscaping in HOA communities |
North Carolina and South Carolina do not have explicit HOA brown-lawn statutes, but municipal water emergency orders generally override HOA covenants under each state’s municipal home-rule doctrine. Document compliance with the specific stage order if your HOA challenges a brown lawn — the order itself is sufficient defense in most cases.
