Replacing old, water-wasting plumbing fixtures with new efficient models is one of the most important steps to help conserve and protect California’s water supplies. Several state and local measures require property owners to install water-conserving plumbing fixtures. The SFPUC and Department of Building Inspection (DBI) are partnering to provide information to building owners on local water efficiency ordinances and how to comply with requirements.
Effective July 1, 2009 two ordinances updated local water efficiency laws for San Francisco properties: the Residential Water Conservation Ordinance and the Commercial Water Conservation Ordinance.
Do the requirements apply to me?
The Commercial Water Conservation Ordinance applies to all existing commercial properties. This ordinance requires commercial building owners to repair plumbing leaks, replace inefficient plumbing fixtures, and submit a completed Commercial Water Conservation Affidavit to DBI by January 1, 2017 that verifies all plumbing fixtures are compliant. All commercial properties must submit a completed affidavit, even if all their plumbing fixtures are already efficient.
How do I comply?
To comply, commercial property owners or an authorized representative shall conduct an inspection to verify all plumbing fixtures in their buildings meet the requirements above and submit to DBI a Commercial Water Conservation Affidavit by mail or in-person to DBI's Commercial Water Conservation Ordinance Counter, Window #8, First Floor, 1660 Mission Street, San Francisco, CA 94103 or by email to dbi.plumbing@sfgov.org. Properties that missed the January 1, 2017 for compliance should submit completed affidavits by 5/18/17 or email DBI at dbi.plumbing@sfgov.org if you believe your building falls under special circumstances.
All noncompliant fixtures that exceed the maximum flow rates noted below must be replaced to before completing the affidavit:
- All showerheads must not exceed a maximum flow of 2.5 gallons per minute (gpm)
- All showers have no more than one showerhead per valve
- All faucets and faucet aerators must not exceed a maximum flow rate of 2.2 gpm
- All water closets (toilets) must not exceed a maximum rated water consumption of 1.6 gallons per flush (gpf)
- All urinals must not exceed a maximum flow rate of 1.0 gpf
- All water leaks have been repaired
Failure to submit an affidavit by the deadline or submitting an affidavit with inaccurate information will result in DBI initiating code enforcement proceedings, which may include monetary penalties and a lien on the property.
Need to replace a non-compliant plumbing fixture?
California plumbing code requires new plumbing fixture installations to meet the following water use rates:
- Showerheads ≤ 2.0 gpm
- Residential kitchen faucet aerators ≤1.8 gpm
- Residential lavatory faucet aerators ≤1.2 gpm
- Commercial/public lavatory faucets ≤ 0.5 gpm
