Summary
Seattle has no year-round lawn-watering-day schedule. SMC 21.04.500 lets the Director of Seattle Public Utilities ban outdoor water use, including irrigation of lawns, turf and other outdoor surfaces, only after declaring a water-supply emergency, and only on the times and conditions the Director then sets for each declared event.
A.The Director of Seattle Public Utilities, upon finding that an emergency situation exists which threatens to seriously disrupt or diminish the municipal water supply, may order and enforce restrictions on water use so as to distribute the available supply on a just and equitable basis to all customers, including residential, industrial, and commercial users, as well as to municipal water districts, other municipalities, and nonprofit water associations which purchase water from the City.B.Upon declaration of a water supply emergency by the Director of Seattle Public Utilities, no water shall be used for outdoor uses including, but not limited to, irrigation of lawns, turf or other outdoor surfaces by any customer at any residence, apartment building, commercial building, or property or structure except at times and under conditions as specified by the Director of Seattle Public Utilities.C.Before putting into effect any restrictions on water use for more than 21 days pursuant to this Section 21.04.500, the Director of Seattle Public Utilities shall explain fully to the Mayor and the City Council the reasons for such restrictions.

Full Breakdown
" The Director sets the actual watering days, hours, and any exemptions administratively for each declared emergency rather than through a fixed schedule printed in the code, so there is no standing odd/even-day or time-of-day watering rule absent an active declaration. If SPU wants to keep restrictions in place for more than 21 days, subsection C requires the Director to explain the reasons fully to the Mayor and City Council before doing so: a built-in check on open-ended restrictions. 505, lets SPU add a daily surcharge on customers who exceed the restrictions or conservation targets set during the emergency, though the surcharge cannot restrict "essential watering of vegetable gardens or ornamental plants," and SPU must publicly announce the restrictions and surcharge amount before billing anyone under it.
Customers who believe a surcharge is an undue burden can ask the Director in writing for an exemption. 580: a gross misdemeanor punishable by a fine of up to $5,000, up to 364 days in jail, or both.
Violations & Fines
Violating an active SPU outdoor-watering emergency order is a gross misdemeanor under SMC 21.04.580, punishable by a fine up to $5,000, up to 364 days in jail, or both. SPU can also impose a daily surcharge under SMC 21.04.505 on any customer whose usage exceeds the declared restrictions or conservation targets, on top of, not instead of, the criminal penalty, once SPU has publicly announced the restriction and surcharge amount.
