Water Conservation Emergency Regulations
As climate change-induced extreme weather continues to disrupt California’s water system, the State Water Resources Control Board has readopted two emergency regulations that prohibit certain wasteful water use practices statewide and encourage Californians to use water wisely and make conservation a way of life. Local water suppliers may have adopted stricter water conservation measures than the State Water Board’s, so water customers should check with local agencies about their current restrictions.

Update
The emergency drought proclamation and emergency water conservation regulations are still in effect: Governor Newsom’s March 24, 2023, Executive Order (N-5-23), which reduced emergency drought requirements, does not immediately terminate current State Water Board (Board) water conservation emergency regulations. Please see below for more details, which are accurate as of June 5, 2023.
- For urban water suppliers, statewide Level 2 demand reduction actions no longer required: The requirement for urban water suppliers to implement demand-reduction actions that correspond to at least Level 2 of their water shortage contingency plans is no longer in effect since June 5, 2023. Local water suppliers may adopt different and/or stricter water conservation measures; check with your supplier about current local restrictions.
- For commercial, institutional, and HOA common areas, decorative grass watering remains banned: TheThe Emergency Regulation to Ban Decorative Grass Watering (non-functional turf irrigation) in commercial, industrial, and institutional areas, including HOA common areas is in effect and the Board may continue to enforce it; it is set to expire in June 2024, unless the Board takes further action. This ban coincides with the state’s long-term goal of Making Conservation a California Way of Life, regardless of the weather.
- For all Californians, prohibition on wasteful water uses remains in effect: The Emergency Regulation to Prohibit Wasteful Water Uses (like refilling fountains without recirculating pumps, overwatering landscapes, watering grass within 48 hours of rainfall, etc.) is set to expire in December 2023, unless the Board takes further action. The Board may continue to enforce these prohibitions and may consider readopting them. Like the decorative grass watering ban, these prohibitions coincide with the state’s long-term goal of Making Conservation a California Way of Life, regardless of the weather.
What current water use restrictions apply to all Californians?
State Water Board water conservation requirements are listed in the table below. There are also requirements not listed here. Column A lists prohibitions on the use of potable water that apply to all Californians. Column B lists additional requirements for urban water suppliers. This table was updated on June 5, 2023.
WHEN IN EFFECT | A. PROHIBITED FOR ALL CALIFORNIANS | B. ADDITIONAL REQUIREMENTS FOR URBAN WATER SUPPLIERS |
---|---|---|
[1] Effective until December 2023 |

Should I follow state and local water use restrictions?
Yes, in most cases you should follow both state and local restrictions. The State Water Board’s restrictions that apply to all Californians are in column A of the table above, which include all the water use prohibitions and the ban on watering decorative grass in commercial, industrial, and institutional areas (including common areas of HOAs). You may also be a customer of a local water supplier that adopted stricter water conservation measures; check with your supplier about their current restrictions. You can find your local water supplier by clicking “Find Local Water Agency” on the website, SaveOurWater.com .
What are HOA requirements during drought emergencies, especially the ban on watering decorative grass?
The ban on using potable water to irrigate decorative grass applies to property a homeowners’ association (HOA) owns or maintains, and not the grass of individual residences (or separate interests). While an individual’s property is considered residential, property owned or maintained by an HOA is treated the same as other landscapes owned by commercial or institutional entities. The regulation does not ban watering grass with recycled water, watering grass regularly used for recreation or community activities, or watering trees or other plants.
An HOA should review areas of grass that it maintains, consult with residents, and determine whether the grass is decorative (“non-functional”). Water suppliers may defer to HOAs’ determinations that specific areas of grass are used for recreation or community events. However, water suppliers also retain the authority to enforce the watering ban if there is a documented violation.
According to the Davis-Stirling Act, an HOA may not impose a fine for reducing watering of lawns or vegetation during a drought emergency that was either declared by the Governor or local government. Additionally, homeowners may remove their lawns and replace them with water-wise plants. If a homeowner installs water-efficient landscaping during the drought, an HOA cannot prevent them from maintaining it or require them to remove it when there is no longer a drought state of emergency. An HOA also cannot prohibit, or include conditions that have the effect of prohibiting, the use of low water-using plants as a group or as a replacement of existing grass.

Current Statewide Water Conservation Emergency Regulations
The water use restrictions table at the top of this webpage is based on current statewide water conservation emergency regulations. The boxes below contain the documents and details of each emergency regulation.
Emergency Regulation to Prohibit Wasteful Water Uses (effective since January 2022)
In 2021, Governor Newsom proclaimed a drought state of emergency for all counties in California, urging Californians to step up their water conservation efforts and encouraging the State Water Board to prohibit certain wasteful water uses. The State Water Board has found that an emergency exists due to drought conditions. To ensure all Californians take sufficient steps to save water and preserve the State’s water supply, the State Water Board has taken the actions in the following timeline.
Timeline
- January 4, 2022: State Water Board adopted the prohibited wasteful water uses emergency regulation.
- December 7, 2022: State Water Board readopted the prohibited wasteful water uses emergency regulation.
- December 21, 2022: Readopted emergency regulation took effect, upon completion of Office of Administrative Law process. It will remain in effect for one year from the effective date, unless the State Water Board modifies it, readopts it, or ends it before then.
Prohibited Wasteful Water Uses Emergency Regulation Requirements (see Regulation Text below for full list of requirements)
- Turn off decorative water fountains
- Turn off/pause your irrigation system when it's raining and for two days after rain
- Use an automatic shutoff nozzle on your water hose
- Use a broom, not water, to clean sidewalks and driveways
- Give trees just what they need: avoid overwatering

Emergency Regulation to Ban Decorative Grass Watering (effective since June 2022)
On March 28, 2022, Governor Newsom directed the State Water Board to consider adopting an emergency regulation to ban decorative grass watering (non-functional turf irrigation) in commercial, industrial, and institutional areas. On March 24, 2023, Governor Newsom’s Executive Order retained a state of emergency for all 58 counties and maintained the ban on wasteful water uses, such as watering decorative grass on commercial properties. To ensure all Californians take sufficient steps to save water and preserve the State’s water supply, the State Water Board has taken the actions in the following timeline.

Emergency Rulemaking Archive
The water conservation emergency regulations below are not in effect. They are listed here only for reference.
Following unprecedented water conservation and plentiful winter rain and snow, on April 7, Governor Edmund G. Brown Jr. ended the drought State of Emergency in most of California, while maintaining water reporting requirements and prohibitions on wasteful practices such as watering during or right after rainfall. Executive Order B‑40‑17 lifts the drought emergency in all California counties except Fresno, Kings, Tulare, and Tuolumne, where emergency drinking water projects will continue to help address diminished groundwater supplies. The Order also rescinds two emergency proclamations from January and April 2014 and four drought-related Executive Orders issued in 2014 and 2015. Executive Order B-40-17 builds on actions taken in Executive Order B‑37‑16, which remains in effect, to continue making water conservation a way of life in California. The State Water Resources Control Board maintains urban water use reporting requirements and prohibitions on wasteful practices such as watering during or after rainfall, hosing off sidewalks and irrigating ornamental turf on public street medians. As directed by Governor Edmund G. Brown Jr. in Executive Order B-37-16, the Board will separately take action to make reporting and wasteful water practices permanent.
State Water Board Partially Repeals Emergency Regulation on April 26, 2017The Executive Director for the State Water Resources Control Board rescinds the water supply stress test requirements and remaining mandatory conservation standards for urban water suppliers. The action was in response to Governor Brown's announcement earlier this month ending the drought state of emergency and transitioning to a permanent framework for making water conservation a California way of life. Current prohibitions against wasteful water use practices and requirements for monthly water use reporting remain in place.
