Rainwater Harvesting

California Water Code 10573 (AB 1750) lets Corona residents collect rainwater in barrels for outdoor use without a permit. Tanks over 5,000 gal or indoor reuse require permits and backflow prevention.

Specific penalty amounts for this ordinance are not published in a publicly accessible fine schedule. Contact [Corona code enforcement](https://leginfo.legislature.ca.gov/faces/codesTOCSelected.xhtml?tocCode=WAT) directly for current fines, enforcement procedures, and hearing options.

If you are coming from a city with tighter rules, you will find Corona gives residents more flexibility on rainwater harvesting.

Water Restrictions

Corona DWP enforces CMC 13.32 with no watering 9 a.m.-6 p.m. and stage-based 2-day-per-week sprinkler limits. AB 1572 phases out potable water on non-functional turf at HOAs by 2031.

Contact [Corona code enforcement](https://leginfo.legislature.ca.gov/faces/codes_displaySection.xhtml?lawCode=CIV&sectionNum=4735) directly for current fines, enforcement procedures, and hearing options.

Corona is more permissive than most cities when it comes to native plants. That said, there are still limits.

Weed Ordinances
