- What days can I water in San Francisco?
- Any day. SFPUC sets no odd/even schedule by address, no assigned weekdays, and no days-per-week cap for landscape irrigation. The only day-based restriction depends on weather, not the calendar: no watering during and within 48 hours after measurable rainfall. SFPUC's advice that watering once or twice a week may be sufficient is written as guidance, and no rule attaches a penalty to exceeding it.
- What hours can sprinklers run in San Francisco?
- There is no citywide clock restriction on landscape watering for general SFPUC retail customers. Section E, Rule 12 contains no time-of-day provision, and the Prevent Water Waste page lists no prohibited hours. A separate provision in the water efficient irrigation rules, Section F, Rule 6, prints "Overhead irrigation shall be scheduled between 8:00 p.m. and 10:00 a.m. unless weather conditions prevent it," and also requires irrigation scheduling to be regulated by automatic irrigation controllers. Section F, Rule 1 aims that at Tier 1 rehabilitated landscape projects of 1,000 square feet up to under 2,500 square feet and Tier 2 projects of 500 square feet or more new or 2,500 square feet or more rehabilitated, yet Rule 1(a)(iii) also extends Section F to "The irrigation and maintenance of any landscape irrigation system," so the scope reads two ways in the source document itself. Treat the window as a landscape ordinance provision tied to irrigation system design and operation, not a general curfew, and ask SFPUC's Water Efficient Irrigation Ordinance staff about a specific property.
- Is there a 9 a.m. to 4 p.m. watering ban or a Level 2 drought stage in San Francisco?
- No. A 9:00 a.m. to 4:00 p.m. irrigation ban, a "Level 2" status with a 15 percent reduction target, $250 and $1,000 citation tiers, a 50 percent tier-2 drought surcharge, and a claim that citations began in November 2025 all circulate on aggregator sites, and none of it appears in SFPUC's own rules or on any SFPUC page. No drought stage, water shortage level, or water shortage emergency is in effect, and no drought banner or service alert appears on sfpuc.gov.
- Can I water when it rains?
- No. Section E, Rule 12(1)(e) prohibits "Application of potable water to outdoor landscapes during and within 48 hours after measurable rainfall." This is a permanent restriction that stays in force year round, independent of any drought stage.
- What is exempt from San Francisco's watering rules?
- There are no drip, hand watering, new planting, edible plant, container pot, hot day, or smart controller exceptions, because SFPUC assigns no watering days or hours and therefore has no schedule to grant exceptions from. The carve-outs sit inside the individual prohibitions instead: hoses are permitted when fitted with a positive shut-off valve; hardscape washing is allowed for health, safety, or to meet City of San Francisco standards for sidewalk cleanliness; eating and drinking establishments can serve drinking water upon request; and construction or dust-control use is prohibited only where recycled water, well water, or groundwater are available, with SFPUC reviewing the fire hydrant meter application. The nonfunctional turf ban does not apply to single-family properties, areas that are the exclusive use of the occupants of an individual dwelling unit, cemeteries, active use areas of parks, sports fields, golf courses, water used to ensure the health of trees and other perennial non-turf plantings, or areas irrigated with recycled water.
- What is the fine for water waste in San Francisco?
- No dollar amount is printed anywhere in SFPUC's rules for outdoor watering or water waste violations, and the escalation is described by process only. Under Section E, Rule 12(4), SFPUC first notifies customers it observes or that are publicly reported to be violating a restriction and advises them of corrective action, by methods that "may include letter, phone call, and dispatch of an inspector." Violators "may be subject to enforcement that could include fines on their water bill, installation of flow restriction devices, injunctions, or other actions as deemed appropriate." No amount, no first, second or third offense tiering, and no per-day figure is stated.
- Does the $1,000 per violation per day fine apply to watering?
- No, and this is the most common mix-up in the SFPUC rules document. The figure "up to $1,000 per violation per day" appears in Section G, Rule 14, which governs cross-connection and backflow prevention under San Francisco Health Code Article 12A. It does not apply to landscape watering or water waste, so treat any site publishing it as a San Francisco watering fine as wrong.
- My address is in San Francisco. Is SFPUC my water supplier?
- Yes. SFPUC is the retail supplier for the entire City and County of San Francisco, including Treasure Island and Yerba Buena Island, so a San Francisco address is served by SFPUC and no other retailer. Immediately south the retailers change to Daly City's municipal water system, the Guadalupe Valley Municipal Improvement District in Brisbane, and North Coast County Water District in Pacifica, each of which sets its own watering rules. The bigger mix-up is regional rather than adjacent: SFPUC wholesales Hetch Hetchy water to 27 cities and public water agencies in Alameda, Santa Clara, and San Mateo counties, including Hayward, Redwood City, Palo Alto, Mountain View, San Bruno and Millbrae, coordinated through BAWSCA. Those households drink SFPUC water but are governed entirely by their own retailer's watering schedule, not by this page.
- How do I report water waste in San Francisco?
- Use San Francisco 311: submit a report at sf311.org or call 3-1-1. Section E, Rule 12(4) states that "The SFPUC directs members of the public to report potential instances of water waste or other violations of this Rule through the City's 311 system. SFPUC staff regularly review and respond to reports submitted." The same 3-1-1 number is SFPUC's 24-hour hotline for water, power, or sewer emergencies and service problems.
