Immovable Obstruction in Golf
What is an immovable obstruction?
An obstruction is any artificial object (not natural) on the course. It is immovable when it cannot be moved without disproportionate effort or without damaging it. The most common examples on the course:
- Cart paths (asphalt, gravel, concrete)
- Sprinkler heads and access covers
- Bridges over penalty areas
- Distance posts or signage
- Buildings and permanent structures
- Fixed fences and boundaries within the course
OB stakes and boundary posts are not obstructions — they are out-of-bounds objects and provide no relief entitlement.
When are you entitled to free relief?
You are entitled to free relief when an immovable obstruction interferes with:
- Where your ball lies (the ball is on or inside the object)
- Your stance (your feet touch or are on the object)
- Your swing area (the club would strike the obstruction during the swing)
You are not entitled to relief simply because the obstruction is on your line of play (the visual trajectory toward the target). The interference must be physical.
Exception: when the stroke is clearly unreasonable
If the only reason the obstruction interferes is because you've chosen an extremely abnormal stroke (for example, playing backwards over your left shoulder to avoid a tree), you have no right to relief. Relief only applies if the obstruction interferes with a reasonably executable stroke toward the target.
How to take relief
-
Determine the Nearest Point of Complete Relief (NPCR): the closest point to your ball where there is no longer any interference, not nearer the hole, in the same playing area (fairway to fairway, rough to rough, etc.).
-
Drop area: 1 club length from that relief point.
-
Drop from knee height within the area.
-
If the ball rolls outside the area, drop again.
Relief on the putting green
If your ball is on the green and an immovable obstruction interferes with your stance or swing, you may place (not drop) the ball at the nearest point of complete relief within the green.
If the obstruction is on your line of putt, you are also entitled to relief on the green (unlike off the green). On the green, line-of-play interference does entitle you to relief.
Common cases: the sprinkler and the cart path
Ball on sprinkler head or on cart path: entitled to relief. The NPCR is usually in the adjacent rough. Important: the NPCR may be in the rough even if your ball was in the fairway — relief goes to the nearest point, not necessarily the best position.
One foot on the cart path when setting up the stroke: entitled to relief even if the ball itself is off the cart path.
Penalty
None. Relief from an immovable obstruction is always without penalty.
Tactical advice
When the NPCR leaves you in a poor position (for example, in thick rough when your ball was in the fairway), evaluate whether you'd prefer to play from the obstruction. You're allowed to not take relief and play the ball as it lies — even on the cart path or sprinkler head — at the risk of damaging your equipment.
