San Diego CA Water Restrictions 2026

Current water restrictions in San Diego, California

San Diego is under Stage 1 Drought Watch restrictions, limiting outdoor watering to 2 days per week on an odd/even address schedule, with watering prohibited between 10 a.m. and 6 p.m.

San Diego Public Utilities declared the Stage 1 Drought Watch in response to the Metropolitan Water District of Southern California (MWD) issuing a Level 1 conservation notice to its 26 member agencies in March 2026. That notice came after the State Water Project allocation was cut to 30% of requested supplies — the result of four consecutive below-average precipitation years across Southern California. San Diego relies heavily on MWD-delivered Colorado River water and State Water Project deliveries, making federal and regional allocation cuts a direct trigger for local restrictions.

The restrictions are mandatory, not voluntary. San Diego Public Utilities administers and enforces them under the city's water shortage response protocols, which align with MWD's tiered conservation framework. Failure to comply can result in enforcement action, beginning with a written warning.

At the state level, California's Level 1 Conservation status reflects system-wide pressure: MWD's declaration affects the entire greater Los Angeles and San Diego metropolitan region, and the city is operating within that broader mandate.

Practically, this means a resident with an even-numbered address — say, 4210 Park Blvd — may run their sprinklers on Wednesday or Sunday, but not during the 10 a.m. to 6 p.m. midday window. Watering on any other day of the week, or running an irrigation system at noon on a permitted day, is a violation. Hand watering with a shut-off nozzle and drip irrigation are exempt from the day restrictions. For current updates and program details, visit San Diego Public Utilities.

Watering schedule and allowed days

Your allowed watering days are determined by whether your street address number is odd or even. The table below summarizes all current rules at a glance.

Rule	Details
Days per week	2
Day assignment	Odd addresses: Tuesday and Saturday; Even addresses: Wednesday and Sunday
Allowed hours	Anytime except 10 a.m. – 6 p.m.
Hand watering	Exempt — shut-off nozzle required
Drip irrigation	Exempt from day restrictions
New sod or seed	30-day establishment window typically available — register with San Diego Public Utilities before installation

Your address number — not your unit number in an apartment or condo — determines your day assignment. For a single-family home at 3317 Grape Street, the odd address means Tuesday and Saturday are your permitted days. Watering before 10 a.m. or after 6 p.m. on those days is required; running sprinklers at any point between 10 a.m. and 6 p.m., even on a permitted day, is a violation.

Multi-family residential and commercial properties follow the same odd/even rule based on the property's street address. If a commercial building has multiple addresses or straddles a parcel boundary, San Diego Public Utilities recommends contacting them directly to confirm which address governs the irrigation schedule. Large commercial landscapes with separate irrigation meters may have additional reporting requirements under Stage 1 protocols.

The midday watering restriction exists to reduce evaporation loss — San Diego's Mediterranean climate means summer afternoon temperatures regularly exceed 75–85°F in coastal neighborhoods and climb well past 90°F inland in communities like El Cajon and Santee, making midday irrigation particularly wasteful. Prioritize deep, infrequent watering during permitted hours for established trees like coastal live oak (Quercus agrifolia), California sycamore (Platanus racemosa), and Torrey pine (Pinus torreyana), all of which are deep-rooted and stressed by shallow, frequent cycles. These species can often go longer between watering sessions than turf, and deep watering every permitted day is better than light daily cycles.

What happens if you violate restrictions in San Diego?

Enforcement under Stage 1 begins with education, not immediate fines. The table below outlines the penalty progression.

Offense	Penalty
First violation	Written warning — no fine
Second violation	Monetary fine issued by San Diego Public Utilities
Subsequent violations	Escalating fines; potential flow restrictor installation on service connection

San Diego Public Utilities enforces restrictions through a combination of complaint-based reporting and field patrols. Residents can report violations online at sandiego.gov/water or through the city's Get It Done app, which routes complaints to the utilities department. Field investigators are dispatched to verify reported violations and typically conduct site visits within a few business days of a complaint. San Diego has also been expanding its Advanced Metering Infrastructure (AMI) smart meter network, which allows utilities staff to identify abnormal consumption patterns — such as daily high-volume usage during restricted hours — without requiring a physical inspection.

If you receive a warning or fine you believe is in error — for example, if drip irrigation was running during the restricted window — San Diego Public Utilities has an appeals process. Contact the department in writing with documentation (photos, irrigation controller logs, or receipts for drip equipment) within the timeframe noted on your notice. Appeals are reviewed by utilities staff, and outcomes are typically communicated within two to three weeks.

Other outdoor water rules

Stage 1 restrictions in San Diego extend well beyond lawn irrigation. Pool evaporation is a significant factor in the region's year-round warm, dry climate, and ornamental water features are addressed specifically. The following rules apply citywide under the current Drought Watch.

• Swimming pools and spas: New pool filling is restricted. Topping off an existing pool to replace evaporation loss is permitted, but draining and refilling is not allowed without a variance. Pool covers are strongly recommended to reduce the approximately 1,000 gallons per month a typical San Diego-area pool loses to evaporation.
• Decorative fountains: Ornamental fountains and water features must use recirculating pumps. Single-pass water features that discharge to drain are prohibited.
• Car washing: Washing vehicles at home is only permitted using a bucket or a hose equipped with a self-closing shut-off nozzle. Running a hose without a shut-off nozzle is prohibited. Commercial car washes that recycle water are an unrestricted alternative.
• Pressure washing: Pressure washing of hardscapes — driveways, sidewalks, patios — is prohibited except when required for health or safety purposes. Preparation for painting or repair may qualify; routine cleaning does not.
• Construction water: Construction site dust control using potable water is subject to Stage 1 limits. Use of reclaimed water for dust control is encouraged and, on some project types, required.
• Restaurants: Restaurants may not serve drinking water to patrons unless the patron requests it — a rule that remains in effect under Stage 1 per California Water Code requirements that activate at this tier.

Water source and infrastructure

San Diego's water supply is almost entirely imported — roughly 85 to 90% of the city's potable water comes from outside the region. The San Diego County Water Authority (SDCWA) is the wholesaler that acquires and delivers water to San Diego Public Utilities and other local retail agencies across the county.

The largest single source is the Colorado River, delivered via the Metropolitan Water District's Colorado River Aqueduct, which runs from Lake Havasu on the Arizona-California border west to Southern California. A secondary import supply comes from the Sacramento-San Joaquin Delta via the State Water Project, transported south through the California Aqueduct. It is this State Water Project allocation that was cut to 30% in 2026, directly triggering MWD's Level 1 conservation notice and San Diego's Stage 1 Drought Watch.

The SDCWA operates two main water treatment facilities serving San Diego: the Otay Water Treatment Plant in the South Bay area and the Skinner Water Treatment Plant in Riverside County (operated by MWD), with treated water delivered into the county system. Locally, San Diego Public Utilities stores treated water in a network of reservoirs including Lake Miramar, Lake Murray, and Sutherland Reservoir in the backcountry. These local surface reservoirs act as emergency and regulatory storage, not primary supply — they do not capture enough local runoff to supply the city independently.

San Diego also has the Claude "Bud" Lewis Carlsbad Desalination Plant, operated by Poseidon Water, which is the largest ocean desalination facility in the Western Hemisphere. It produces approximately 50 million gallons per day, supplying about 10% of the county's water demand and providing a drought-independent local supply. Despite this buffer, the overall system remains heavily dependent on imported water, which is why reduced State Water Project allocations translate quickly into mandatory local restrictions.

Brown lawn protections in California

California law explicitly protects homeowners from HOA fines for drought-related lawn browning. Under California Government Code § 65595 and the protections established by AB 2100, a homeowner's association may not fine or penalize a property owner for allowing their lawn to go brown or reducing irrigation during a declared water shortage emergency or drought. This protection applies during San Diego's current Stage 1 Drought Watch, which constitutes a mandatory water conservation condition under state law.

Additionally, California Civil Code § 4735 prohibits HOAs from requiring homeowners to use water-intensive landscaping and bars enforcement of any rule that prevents compliance with a water-shortage emergency order. If your HOA has issued a fine or a notice of violation for a brown lawn or reduced irrigation while Stage 1 restrictions are active, that action is not enforceable under state law.

If your HOA is pressuring you to water beyond what Stage 1 allows, or fining you for a brown lawn, use the following as a starting-point response:

"I am writing to inform [HOA Name] that my current irrigation practices are required by San Diego Public Utilities' mandatory Stage 1 Drought Watch restrictions, which limit outdoor watering to two days per week. Under California Government Code § 65595 and Civil Code § 4735, homeowners associations are prohibited from fining or penalizing residents for reduced irrigation or drought-related lawn browning during declared water shortage conditions. I request that this fine/notice be rescinded immediately. If you have questions about the applicable restrictions, please contact San Diego Public Utilities at sandiego.gov/water."

Lawn care during restrictions

San Diego's Mediterranean climate — dry summers, mild winters, and moderate coastal humidity — supports a specific set of turfgrasses. The table below covers the grasses actually grown in San Diego yards and how they respond to twice-weekly irrigation under Stage 1.

Grass Type	Drought Tolerance	Survives 2x/Week Watering?	Notes
Bermudagrass	High	Yes	Goes dormant in cooler months; thrives in San Diego summers; very low water needs once established
Tall Fescue	Moderate	Yes, with deep watering	Performs well in coastal and inland San Diego; requires longer run times on permitted days
UC Verde Buffalograss	Very High	Yes — may need only once/week	Developed by UC Davis for California; excellent choice for water-restricted landscapes
Kikuyugrass	Moderate–High	Yes	Common in San Diego but invasive; aggressive grower that can handle restriction periods

During Stage 1, the most important adjustment for San Diego homeowners is to shift irrigation run times to early morning — before 10 a.m. — on permitted days, and to run each zone long enough to wet the soil 6 to 8 inches deep. San Diego's coastal soils often include clay layers that slow percolation, particularly in neighborhoods like Kensington, North Park, and Clairemont, so slower, longer cycles with soak periods will outperform short, rapid runs. Tall Fescue in particular needs this deep watering approach during summer to maintain root depth and avoid surface stress.

If your lawn is showing stress under the current restriction schedule, this is a practical moment to evaluate turf removal. San Diego Public Utilities offers rebates for replacing turf with drought-tolerant landscaping, and the Regional Water Authority's WaterSmart program provides additional incentives. Bermudagrass and UC Verde Buffalograss are the lowest-water options for homeowners who want to keep some turf. Mow Bermuda to 1–1.5 inches and Tall Fescue to 3–4 inches during summer — taller blades shade root zones and reduce soil moisture loss between permitted watering days.

Common questions about San Diego water restrictions

What days can I water if my address is odd — say, 3317 Grape Street in San Diego?

An odd-numbered address like 3317 is assigned Tuesday and Saturday as your two permitted watering days. You may run your sprinkler system or irrigation before 10 a.m. or after 6 p.m. on those days only. Watering on any other day of the week — including if a neighbor or gardener shows up on a Monday — is a violation of the Stage 1 mandatory restrictions.

What days can I water if my address is even — for example, 4210 Park Blvd?

Even-numbered addresses are assigned Wednesday and Sunday. The same time restriction applies: no watering between 10 a.m. and 6 p.m. on those days. Early morning watering — beginning at 5 or 6 a.m. — is the most efficient option and is fully compliant with current Stage 1 rules.

Can I wash my car at home in San Diego right now?

Yes, but only with a bucket or a hose fitted with a self-closing shut-off nozzle. Running an open hose over your car — the kind that flows continuously while you're not actively spraying — is prohibited under Stage 1 restrictions. Commercial car washes that recycle their wash water are a fully unrestricted alternative and are often the more water-efficient choice.

Does San Diego Public Utilities use smart meters to catch violations?

Yes, increasingly so. San Diego has been deploying Advanced Metering Infrastructure (AMI) smart meters across the service area, which transmit usage data at regular intervals throughout the day. Utilities staff can flag accounts showing high consumption during the prohibited 10 a.m. to 6 p.m. window or consistent daily irrigation that exceeds two-day-per-week patterns. This data can support enforcement action without requiring a neighbor complaint or physical patrol observation.

Does drip irrigation count toward my two allowed days per week?

No. Drip irrigation is exempt from the day-of-week restrictions under San Diego's Stage 1 rules. You may run drip systems any day of the week, at any hour. This exemption applies to true drip systems — emitters that deliver water directly to the root zone at low flow rates. Microspray heads that broadcast water above the soil surface are generally not considered drip and are subject to the standard schedule.

What rebates does San Diego Public Utilities offer for removing turf?

San Diego Public Utilities offers turf replacement rebates through its WaterSmart Landscape Rebate program. As of 2026, rebates are available for converting irrigated turf to drought-tolerant or California-native landscaping. The Regional Water Authority, which serves the broader San Diego County area, also administers rebates through the regional WaterSmart program, and MWD offers rebates layered on top of local utility incentives. Check sandiego.gov/water for current per-square-foot amounts, as rebate levels adjust based on available program funding.

What happens to my landscaping contractor — are they subject to the restrictions too?

Yes. Landscaping contractors operating on your property are bound by the same Stage 1 restrictions that apply to you as the property owner. If your gardener runs irrigation on a non-permitted day or during the 10 a.m. to 6 p.m. window, the violation is recorded against your address and service account, not the contractor's license. Make sure your landscaping crew has your correct permitted days and understands the midday prohibition — you are responsible for what happens on your property.

How long will Stage 1 restrictions stay in effect in San Diego?

The current Stage 1 Drought Watch does not have a fixed end date. San Diego Public Utilities has stated restrictions will remain in place until conditions improve — specifically, until MWD's Level 1 conservation notice is lifted and State Water Project allocations recover to levels that remove the supply pressure triggering local action. MWD's declaration is tied to annual hydrology and State Water Project allocation reviews, so the earliest a meaningful reassessment would occur is during the 2026–2027 water year allocation cycle. Monitor sandiego.gov/water for any updates to the restriction phase.

What time can I water in San Diego?

Watering is allowed Not 10am-6pm. Watering outside these hours is a violation even on your assigned day.

What are the fines for watering violations in San Diego?

First offense: Warning first. Repeat violations: Fines. Contact San Diego Public Utilities for the full enforcement schedule.

When will water restrictions end in San Diego?

Current Stage 1 Drought Watch restrictions are in effect through Until conditions improve. Monitor https://www.sandiego.gov/water for the latest status.

Can I hand water during San Diego water restrictions?

Yes. Hand watering with a hose fitted with a shut-off nozzle is generally allowed on any day during permitted hours. Drip irrigation and soaker hoses are also typically exempt from the day-of-week schedule. Confirm specifics with San Diego Public Utilities.

How do I report a water waste violation in San Diego?

Contact San Diego Public Utilities or visit https://www.sandiego.gov/water. Most utilities accept online reports and respond within 48 hours.
