Want to avoid fines, protect your landscaping, and keep your water bill in check? San Diego has permanent water rules that apply year round, with extra limits added during drought levels. If you understand the basics, you can stay compliant and still keep your yard healthy. This quick playbook walks you through what the rules mean, how they are enforced, and simple steps to save water and money. Let’s dive in.
How San Diego water rules work
San Diego’s water rules come from several layers. The State sets efficiency targets that guide local planning, which influence how cities and water districts manage use and enforce conservation. You can read the state framework that shapes indoor targets in the Department of Water Resources summary. California’s guidance on indoor standards helps frame local policy.
Locally, the San Diego County Water Authority recommends measures that retail agencies can adopt during drought response levels. Member agencies, including the City of San Diego, set and enforce the actual rules for their customers. Start by confirming who bills you so you follow the right rulebook. Use the Water Authority’s locator to find your water district.
Year round rules you must follow
If you are a City of San Diego water customer, these permanent rules are always in effect. Other local agencies have similar measures, but timelines and penalties can vary. Review the City’s summary of current water use restrictions before you adjust your routine.
- No runoff. Do not let irrigation water run onto sidewalks, streets, storm drains, parking areas, or adjacent properties.
- Fix leaks within 72 hours. Repair or stop leaks as soon as you discover them or within 72 hours of a notice from your provider.
- Water before 10 a.m. or after 6 p.m. Limit outdoor watering to these time windows for landscapes, potted plants, fruit trees, and home gardens.
- Pause watering after rain. Do not irrigate during rain or within 48 hours after measurable rainfall.
- Use a shutoff nozzle. If you hand water or wash a vehicle at home, your hose must have a positive shutoff nozzle. Commercial car washes that recirculate are preferred.
- Fountains and pools. Ornamental fountains must use recirculating systems. Avoid overfilling pools and spas.
- Median turf. Potable water cannot be used for ornamental turf on public street medians.
When drought levels kick in
During declared drought levels, your provider may limit irrigation to specific days per week, set maximum run times per station, or restrict washing down paved surfaces except for health and safety. Agencies often use the Water Authority’s model measures when they add these temporary limits. Check announcements from your provider and review the Water Authority’s recommended mandatory restrictions to understand what may apply.
How enforcement works
Local agencies prioritize education first. If there is a report of water waste, expect an inspection and a notice with steps to fix the issue. The City outlines its approach and penalties on the enforcement page.
Continued violations can lead to administrative fines that escalate, with City examples ranging from $100 to $1,000. Egregious or repeated waste can result in further action, which can include service shutoff. If runoff reaches storm drains, stormwater enforcement may also get involved. Remember that rules and fine schedules can differ by agency, so always confirm with your provider.
Your step by step action plan
Confirm your provider. Use the locator to find your water district, then bookmark your agency’s conservation page.
Audit your irrigation. Check for broken heads, misdirected spray, and overspray onto hardscapes. Adjust heads and schedules to stop runoff.
Set your timer. Water only before 10 a.m. or after 6 p.m., and turn controllers off when rain is forecast. Use a rain sensor if your system supports it.
Fix leaks fast. If you get a notice, aim to repair within 72 hours. Track your bill for sudden jumps that can signal hidden leaks.
Schedule a free survey. City customers can request a residential water survey to identify savings at home.
Tap into rebates. Check City programs for turf replacement, rain barrels, and more on the rebates and conservation page. Many programs require pre approval before you start work.
Upgrade smart. Explore Weather Based Irrigation Controllers, flow sensors, and audits available through the Water Authority’s residential rebates and programs.
Consider graywater. Simple laundry to landscape systems may have streamlined permitting, while larger systems need plans and permits. Review the City’s Gray Water Systems bulletin before you design anything.
Big picture supply to watch
