Residential Water Conservation Ordinance

Under San Francisco’s Residential Water Conservation Ordinance, a real property owner must:

  • Equip showers with low flow devices limiting the water flow rate to 2.5 gallons per minute or less.
  • Attach aerators to applicable sink faucets.
  • Install low flow toilets or install devices designed to limit the water flow of an existing toilet.

A water conservation inspection and the appropriate changes must occur before transfer of title from seller to buyer can occur. The costs of water compliance are NOT applied to the cost limits associated with the energy conservation ordinance.  For specific questions, you can contact the Water Department at 415-551-3000.
