Upland, CA Landscaping Rules: Rainwater Harvesting (2026)

No specific City of Upland ordinance prohibiting or licensing residential rain barrels or cisterns was identified in the City's published municipal code. In California, rainwater capture from rooftops for landscape and non-potable use is broadly permitted under the Rainwater Capture Act of 2012 (AB 1750), which lets residential, commercial and industrial property owners install rainwater capture systems without a water-rights permit from the State Water Resources Control Board. Larger or plumbed systems may still require a plumbing/building permit, and Upland's adopted California Plumbing Code governs any system tied into household plumbing. Upland's own Water-Efficient Landscape ordinance (UMC Chapter 17.12) is built around reducing applied water and is stated to be at least as effective as the State's model ordinance, consistent with on-site stormwater capture being encouraged for qualifying projects. Because Upland operates its own water utility, residents seeking incentives or guidance should check City and regional (IEUA/MWD) conservation programs. As always, confirm current permit thresholds with City Building & Safety before installing a large cistern. Where the City is silent, State law controls — capture is allowed.
