How the rule works
San José Municipal Water System customers have no assigned watering days, but irrigation is banned between 10 a.m. and 8 p.m. every day under Municipal Code Section 15.10.290. Sprinklers and other irrigation systems also stop at 15 minutes per station per day. These are permanent rules that run all year. Watering by bucket, by a hose with a self-closing nozzle, or by drip is exempt from the hours. Valley Water Ordinance 23-02, which covers properties whose water Valley Water supplies or manages, adds a ban on overhead sprinklers from 9 a.m. to 6 p.m. and a rain rule: no landscape watering during and within 48 hours after at least 0.25 inches of rain. Where it applies, sprinklers stay off from 9 a.m. to 8 p.m. The City names no water shortage in force: the Council ended the last shortage declaration in August 2023, and no day limits apply without one.

San Jose Muni Water rules and fines
Current stage No water shortage stage is declared. The City Council ended the city-wide water shortage in August 2023 (Resolution RES2023-287), which had been declared on November 30, 2021 (Resolution 80303) and extended by Resolution 80749. The 2025 Water Shortage Contingency Plan, adopted by the Council in June 2026 (RES2026-169), defines six shortage levels that start only when the Council declares a shortage; without a declaration the system is in a functional Stage 0, and the permanent rules of Chapter 15.10, Part 2, stay in force at all times.
The exceptions include drip irrigation, hand watering, new plantings, smart controllers, recycled water and fixing or testing sprinklers, each with its own conditions. A written exception can also be requested. The full text is below.
First: $250. Then $500 within 12 months.

Exceptions to the San Jose Muni Water rules
- The 10 a.m. to 8 p.m. ban does not apply when watering with a bucket, a hand-carried container, a hose equipped with an automatic positive self-closing valve, or a drip irrigation system (15.10.290 A).
- The 15-minute cap does not apply to a continuously attended hose with a self-closing valve, very low-flow drip systems with no emitter above two gallons per hour, irrigation systems with weather-based controllers, or stream rotor sprinklers that meet a 71 percent efficiency standard (15.10.290 B).
- Neither limit applies during plant Establishment Periods, which Section 15.11.390 defines as the first year after installing plants, or the first two years if irrigation will end after establishment, or while a landscape water management audit evaluates and adjusts the system (15.10.290 C). Golf and bowling green syringing is also exempt.
- The limits cover potable water. Reclaimed (recycled) water and graywater are not potable water under Section 15.10.030 B. Where a recycled water system is installed and recycled water is available, potable water may not be used for that irrigation (15.10.295).
- Rain: Valley Water Ordinance 23-02, Section 3.1(c), bans watering outdoor landscapes during and within 48 hours after measurable daily rainfall of at least 0.25 inches, judged from the closest National Weather Service or Valley Water ALERT station.
- No water use that runs off onto sidewalks, driveways, gutters or streets, or beyond the immediate area of use, or that pools or puddles (15.10.220).
- Start repairing leaking or broken pipes, faucets, sprinklers and irrigation systems within five working days after learning of them, and finish as soon as practical (15.10.210).
- Hoses used to clean buildings, sidewalks, driveways, patios or other hard surfaces, or to wash vehicles, need an automatic positive self-closing valve (15.10.240 and 15.10.250).
- Anyone seeking an exception from a potable water rule in Chapter 15.10 files a written request on a City form, with an exception review fee, showing that no other water source can be used (15.10.380).

San Jose Muni Water watering questions
Does San Jose Muni Water assign watering days by address?
No. Chapter 15.10 of the San José Municipal Code sets no even or odd split and no weekday schedule for Muni Water customers. It limits the clock and the run time instead. Day limits under Section 15.10.310 start only if the City Council declares a water shortage, and none is declared today.
What hours can sprinklers run in the Muni Water service area?
Before 10 a.m. or after 8 p.m. Section 15.10.290 A bans irrigating outdoor landscaping with drinking water between 10:00 a.m. and 8:00 p.m. Valley Water's Ordinance 23-02 separately bans overhead irrigation from 9 a.m. to 6 p.m. on properties whose water it supplies or manages, such as Evergreen, which gets Valley Water treated water; there, sprinklers stay off from 9 a.m. to 8 p.m.
Can I hand water or use drip irrigation during the day in San Jose?
Yes. The 10 a.m. to 8 p.m. ban in Section 15.10.290 A does not cover watering with a bucket, a hand-carried container, a hose with an automatic positive self-closing valve, or a drip irrigation system. The residents page names only the hose and bucket, but the code text also lists drip.
How long can each sprinkler station run on a Muni Water account?
At most 15 minutes per station per day under Section 15.10.290 B. The cap does not apply to a continuously attended hose with a self-closing valve, very low-flow drip with no emitter above two gallons per hour, systems with weather-based controllers, or stream rotor sprinklers that meet a 71 percent efficiency standard. New plantings in their establishment period and irrigation audits are exempt as well (15.10.290 C).
What are the fines for watering at the wrong time in San Jose?
The City's Administrative Citation Schedule of Fines, Resolution RES2025-403, sets $250 for a first violation of Section 15.10.290 and $500 for a second or later violation within 12 months of the previous one. Runoff, leak repair and hose rules carry the same amounts. Valley Water is not issuing its own water waste fines while it has no mandatory reduction call.
Is San Jose under a drought stage or water shortage right now?
The City names none. The Council declared a 15 percent water shortage in November 2021 and ended it in August 2023 with Resolution RES2023-287. The 2025 Water Shortage Contingency Plan, adopted in June 2026, starts its six shortage levels only on a Council declaration and calls the condition without one a functional Stage 0, when only the permanent Chapter 15.10 rules apply.
Is my San Jose home served by Muni Water?
Only if it sits in one of Muni Water's four service areas: North San José and Alviso, Evergreen, Edenvale or Coyote Valley. San José has three water retailers, and other homes are billed by San Jose Water Company or Great Oaks Water Company. The City's water retailer lookup and the name on the water bill settle it.
How do I report water waste in the Muni Water area?
The City's Report Water Waste page sends reports to Valley Water: call (408) 630-2000, submit an online request through Access Valley Water, or use the Access Valley Water mobile app. Valley Water passes repeat complaints to the water retailer for enforcement.
