Water Use Rules in Corona, CA

Corona maintains 149 local ordinances across all categories, and 3 of those deal specifically with water use rules. Here is a breakdown of what the city actually requires, what is prohibited, and where Corona falls on the strict-to-permissive spectrum compared to other cities.

Leak Reporting Duty

Corona law makes failing to repair a water leak an unlawful "unreasonable use of water" at all times, alongside letting irrigation or leak runoff drain onto streets and neighboring property. The rule applies regardless of which water conservation stage the city has declared, so it never becomes optional.

Key details: Governing rule: Failing to repair a leak is unlawful. Applies: At all times, every conservation stage. First violation: Written notice within two weeks. Repeat violation: Flow restrictor or service shutoff. Maximum penalty: $1,000 fine or 30 days jail.

A first leak-related violation triggers a written notice or enforcement-officer visit under § 13.26.120 describing the required fix and possible consequences. A second or later violation can lead to installation of a flow-restricting device on the service line or discontinuance of water service. Any willful violation is also a misdemeanor under § 13.26.110, punishable by up to 30 days in county jail, a fine of up to $1,000, or both, under California Water Code § 377, and the city may separately pursue injunctive relief in Superior Court.

Recycled Water Rules

Corona runs a dedicated reclaimed water program under Municipal Code Chapter 13.28, requiring a citywide Reclaimed Water Master Plan and allowing the city to condition new development, remodels, and even existing customers on converting from potable to reclaimed water for irrigation and other approved uses.

Key details: Governing chapter: Corona Municipal Code Ch. 13.28. Master Plan update cycle: At least every 5 years. New development: Reclaimed water can be a permit condition. Existing customer objection window: 30 days from notice. Council appeal window: 10 days after Director's decision.

Section 13.28.070(A) declares any discharge of wastes or use of reclaimed water in violation of the chapter or a permit, including using reclaimed water for potable purposes or introducing it into a potable system, a public nuisance to be abated by the city; anyone creating that nuisance is guilty of a misdemeanor. The city can also issue cease-and-desist orders and pursue other administrative enforcement powers under § 13.28.070(B) against noncompliant permit holders.

Turf Replacement Rebates

Corona lets residents rip out parkway turf for water-efficient landscaping without an encroachment permit, under Corona Code of Ordinances § 12.08.010(B), as long as digging stays under 12 inches deep, new plants top out under 18 inches, and the replacement plants come from the city's approved landscape list. Skip a condition and the standard encroachment permit from the City Engineer applies instead.

Key details: Encroachment permit needed: No, if conditions met. Max excavation depth: 12 inches. Max mature plant height: 18 inches. Required call before digging: USA of Southern California. Replacement plants: From city landscape guidelines/list.

Removing parkway turf without meeting all seven conditions in § 12.08.010(B), and without first getting an encroachment permit, is declared a nuisance under § 12.08.010(A), exposing the property owner to the enforcement actions and penalties set out elsewhere in the Corona Municipal Code.

The rules around turf replacement rebates in Corona lean permissive, but that does not mean anything goes.

The Bottom Line

Corona's water use rules rules are a mixed bag. Some areas are strict, others are relaxed, and the details matter. The best approach is to check the specific rule that applies to your situation rather than assuming Corona is broadly strict or permissive.
