Commercial Efficiency Requirements

Mandatory Water Efficiency for Commercial Water Users

Every non-residential building is required to have water efficient toilets, urinals and faucets. Businesses that have showerheads, ice machines and/or clothes washers must have water efficient models. These requirements applied to all businesses as of December 31, 2013. Visitor serving businesses (such as hotels and restaurants) were required to install water efficient devices by January 1, 2001. All visitor serving accommodations must have linen and towel reuse programs in place, and all public restrooms must have water conservation messages posted. Restaurants are only to serve water when requested.

Questions about these programs should be addressed to or call 831-658-5601.
