Does your neighborhood have watering restrictions?
Often those restrictions apply primarily to automatic sprinkler systems. Hand-watering with a hand held hose is still permitted in many local ordinances.
That means you can keep potted plants, prized shrubs, and new transplants happy without breaking the rules. 
Always check your city’s website for the current drought stage and any time-of-day limits (watering is often restricted during the heat of the day). Happy gardening!
