Allowed Watering Hours
No outdoor irrigation between 9:00 AM and 4:00 PM. Under Level 2, SFPUC requires a 15% reduction in total water use compared to the customer's prior year baseline, this overall cap replaces rigid day-of-week scheduling for single-family residential customers.
Still Allowed
💧 Hand Watering
Allowed with shut-off nozzle. Hours: Any time outside the 9:00 AM – 4:00 PM blackout.
🌿 Drip Irrigation
Exempt from day-of-week limits. Must follow allowed hours.
Fines & Enforcement
$250 per violation
SFPUC enforcement is primarily education-first for residential customers but commercial properties, multi-family buildings, and HOAs face citations starting at $250 for first violations and up to $1,000 for repeat offenses within 12 months. Chronic non-compliance can add a 'drought surcharge' to the monthly bill equal to 50% of the tier-2 rate.
Citations begin November 2025🏠 HOA Rules During Restrictions
California Water Code §10631.5 and Civil Code §4735 prohibit HOAs from fining residents for drought-compliant brown lawns during declared shortage and protect homeowners who reduce irrigation to meet conservation orders. SFPUC's Level 2 declaration qualifies as the state-recognized trigger.
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 San Francisco Public Utilities Commission. 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
SFPUC's Hetch Hetchy Regional Water System delivers water to 2.7 million Bay Area residents. The Hetch Hetchy Reservoir is at 72% capacity (normal 83% for April), but San Francisco's 2026 allocation from the Regional Water System was cut 15% due to reduced Sierra snowpack (only 62% of normal) and Tuolumne River flow commitments to downstream senior rights holders. Level 2 mandatory rationing reflects this allocation cut rather than local reservoir-only conditions.
This deficit has accumulated over the current water year and represents a significant departure from historical averages for the San Francisco area. Water supply reservoirs and aquifer levels are well below seasonal targets, necessitating mandatory conservation measures.
How to Keep Your Lawn Alive During San Francisco Water Restrictions
11 tips tailored for San Francisco homeowners during Level 2 Mandatory Water Rationing restrictions.
San Francisco's fog belt moderates lawn water demand, most west-side neighborhoods (Sunset, Richmond) can cut irrigation days in half April through September.
Replace tall fescue with Kurapia or UC Verde Buffalo Grass, both handle SF's cool summers and use roughly 60% less water than traditional lawns.
Stack rebates: SFPUC's Lawn Be Gone ($3/sq ft) plus regional turf-removal credits for up to $5/sq ft combined.
Use PG&E-certified smart controllers with a separate rain sensor, rebates cover up to $100 on Hunter Hydrawise and Rachio units.
Sheet-mulch lawns to remove without digging: cardboard, 4 inches of compost, then wood chips, ready to plant in 60–90 days.
Drip-irrigate all trees and shrubs on a separate valve, SF's sandy western neighborhoods lose 2x the moisture of clay-dominant eastern ones.
Harvest shower warm-up water, SF allows simple greywater laundry-to-landscape systems under the California Plumbing Code without a permit.
Track monthly consumption at sfpuc.org 'My SFPUC Account', Level 2 requires a documented 15% reduction versus 2023 baseline.
Apply foggy-day irrigation strategy: SF's marine layer delivers measurable moisture Jun–Sep, skip irrigation days after 3+ fog mornings in a row.
Fix outdoor hose bibs with anti-siphon shut-off valves, recommended by the SFPUC to eliminate inadvertent drips.
Replace any remaining overhead spray in narrow side yards with subsurface drip, saves 40% versus pop-up sprays in SF's windy corridors.
