You generally must not park within 15 feet (about 4.5 meters) of a fire hydrant in many places.

Short answer

  • In a lot of U.S. and Canadian cities, the standard rule of thumb is 15 feet ≈ 4.5 meters from the hydrant.
  • Some local laws allow slightly less (around 3–4 meters), but 15 feet / 4.5 meters keeps you safe almost everywhere.

If you’re asking for a specific country or city (for example, UK, Ireland, India, Singapore, etc.), tell me your location and I can explain how that area handles fire hydrants and parking near them.
