Under PCWA Stage 2 of its Water Shortage Contingency Plan, turf irrigation is limited to 3 days/week in July-September and 2 days/week in April-June and October-November, with watering only between 7 p.m. and 7 a.m. Washing down sidewalks and driveways is prohibited unless required for public safety.

Heavy RestrictionsRainwater Harvesting
Rocklin has no city-specific rainwater harvesting ordinance. Residential rainwater capture is governed by California Plumbing Code (Title 24 Part 5) Chapter 17 - Nonpotable Rainwater Catchment Systems and the California Rainwater Capture Act (Water Code 10574). Outdoor barrels under 360 gallons used for landscape irrigation generally require no permit; cistern systems with potable plumbing connections require a Building Division plumbing permit.
Rainwater Harvesting - No Local Ordinance; California Plumbing Code Ch 17 Applies
Few RestrictionsNative Plants
Rocklin requires all new-construction residential landscape plans to comply with the California Model Water Efficient Landscape Ordinance (MWELO), in effect since December 1, 2015. The City publishes Residential Landscape Templates that guide homeowners toward water-efficient and drought-tolerant plant choices, including native species. Civil Code 4735 preempts HOA bans on drought-tolerant landscaping during a declared drought.

On lots over 5,000 sq ft, no more than 60% of the front yard (and corner-lot street-side yard) may be impermeable surface; at least 40% must be permeable (grass, soil, landscaping, rock aggregate, decomposed granite, or similar).
