Rule 16.1

Ground under repair — free relief, if it really is GUR

Ground under repair is free relief under Rule 16.1: drop within one club-length of the nearest point of complete relief, no nearer the hole. But you only get relief if the GUR interferes with your lie, your stance or your swing — and several things golfers assume are GUR are not.

The short answer

What counts as ground under repair?

Ground under repair is any part of the course the committee defines as being under repair, and it also includes a small set of situations that are GUR automatically, even unmarked:

Most GUR, though, is simply whatever the committee marks — usually with white lines, stakes or a GUR sign. The defined area includes all the ground inside its edges, plus any grass, bushes, trees and natural objects growing in it.

Relief is free — here's how to take it

  1. Find the nearest point of complete relief. Nearest spot to the ball, no nearer the hole, where the GUR no longer interferes.
  2. Take one club-length from that reference point as your relief area.
  3. Drop from knee height. If the ball rolls out, re-drop; if it rolls out again, place it where the second drop first touched the ground.

"Complete relief" is the trap. You cannot stand in ground under repair to play a shot — even if your ball is outside it. If your stance or your swing touches the GUR, you are not fully relieved and playing from there is a general penalty (two strokes in stroke play, loss of hole in match play).

You don't have to take relief

Unless the area is a No Play Zone, you are always allowed to play the ball as it lies from ground under repair. Plenty of players drop out of GUR when they had a perfectly good lie inside it. If you like the lie, play it.

Things that are NOT automatically GUR

You might think it's GUR…Reality
Tractor or vehicle rutsNot GUR by default. A committee is justified in declaring deep ruts GUR but it is not automatic — check the Local Rules.
Old hole plugs, sunk below the green surfaceNot automatically GUR. On the putting green you may repair the damage under Rule 13.1c instead.
Fallen trees or un-cut tree stumpsNot automatic. They must be unearthed or cut up for later removal to qualify.
A bare, thin or patchy lieJust a bad lie. Play it or declare it unplayable.
A divot hole in the fairwayNo free relief — divots are not GUR unless a local rule says so.

When you can't find the ball in GUR

Rule 16.1e covers the case where your ball has not been found, but it is known or virtually certain that it came to rest in or on ground under repair. Instead of stroke and distance, you take free relief: estimate the point where the ball last crossed the edge of the GUR, use that as the starting point for the nearest point of complete relief, and drop within one club-length, no nearer the hole.

"Virtually certain" is a high bar — about 95% confidence. If there is a real chance the ball rolled past the GUR into thick rough, you don't get this relief and the ball is simply lost.

Frequently asked questions

Do you get a free drop from ground under repair?
Yes. Ground under repair is an abnormal course condition under Rule 16.1, so relief is free. You find the nearest point of complete relief no nearer the hole and drop within one club-length of it.
How do you know if an area is ground under repair?
Usually it is marked with white lines, stakes or a GUR sign, and the defined area includes the ground inside the edges plus anything growing in it. A few situations are GUR automatically even when unmarked: holes made by staff, organic material piled for removal, and animal habitats.
Can you play the ball from ground under repair?
Yes — unless the area is a No Play Zone, you are always allowed to play your ball as it lies from GUR. Relief is available to you, not compulsory.
Are tractor ruts ground under repair?
Not automatically. A committee is justified in declaring deep ruts to be ground under repair but it is not automatic, so you must check the Local Rules before assuming you get a free drop.
What happens if you can't find your ball but you know it's in ground under repair?
Rule 16.1e gives you free relief provided it is known or virtually certain (about 95% confidence) that the ball came to rest in the GUR. You estimate the point where it crossed the edge and take relief from there instead of stroke and distance.
