Full Breakdown

Section 15.10.290 of the Municipal Code bars anyone from using potable water to irrigate outdoor landscaping between 10:00 a.m. and 8:00 p.m., regardless of the method, and separately limits landscape-irrigation-system watering to fifteen minutes per station per day. The time-of-day ban does not apply to bucket or hand-carried-container watering, a hose fitted with an automatic positive self-closing valve, or drip irrigation. Weather-based controllers and high-efficiency stream rotor sprinklers are exempt from the fifteen-minute cap, as is syringing of golf greens and tennis courts. If the city council later declares a water shortage of ten percent or more, § 15.10.310 lets it further restrict watering to as few as zero to four days per week by resolution.

San Jose's code carries no dedicated penalty for Chapter 15.10; violations default to Municipal Code § 1.08.010 as a misdemeanor, up to $1,000 and six months' jail, with each day of continued violation a separate offense.
