Ground Under Repair
In short
Ground under repair is a part of the golf course that the Committee has defined for repair or maintenance, such as a building site or a dug-up area. If your ball lies in it, or it interferes with your stance or swing, Rule 16.1 lets you take relief without penalty and drop within one club-length.
What does ground under repair mean in golf?
Ground under repair is an area of the course that is being repaired or maintained. It is abbreviated GUR. Typical examples are dug-up areas, building sites, newly laid turf or places where greenkeepers renovate the soil.
The basic idea is simple. Such areas are not part of the normal challenge of the course, so you should not be punished for landing there. That is why free relief exists. The Rules of Golf group ground under repair with animal holes, immovable obstructions and temporary water under the heading abnormal course conditions. They are covered by Rule 16.1.
Ground under repair is any part of the course that the Committee defines as such, marked or not. Even without markings, holes dug by maintenance staff and material piled up for removal, such as grass cuttings, count. The area also includes the ground and everything rooted in it. The edge extends vertically down but not up. A tree growing in the area still counts as part of it.
How is ground under repair marked?
The Committee usually marks the area with white lines, often with stakes as well. These stakes are frequently blue. Yellow and red are reserved for penalty areas so that nothing gets confused. If in doubt, the Local Rules on the scorecard or the notice in the clubhouse tell you which colour applies.
If lines and stakes are both present, the line defines the edge. The line itself is part of the ground under repair. The stakes themselves are not the boundary but obstructions. If they are movable and in the way, you may remove them. Put them back afterwards.
One important point: marking is not compulsory. An area can be ground under repair without any lines if the Committee has defined it so. A fresh pile of grass cuttings also counts as long as it is meant for removal. If in doubt, ask the Committee before or after the stroke, or play two balls in stroke play when you are unsure of the ruling.
Relief under Rule 16.1: how to proceed
You get relief if your ball lies in or touches ground under repair. You are also entitled to it if the area interferes with your stance or your swing. If the ball is on the putting green, an area on the green that intervenes on your line of putt can also give relief.
In the general area, proceed like this:
- For orientation, mark the position of your ball, for example with a tee.
- Find the nearest point of complete relief. This is the spot closest to the ball, no nearer the hole, where neither ball nor stance nor swing is interfered with by the area. Think of the club you would use for the next stroke.
- Drop a ball within one club-length of that point. The relief area is in the general area and must not be nearer the hole.
A club-length is the length of the longest club in your bag other than the putter. You may use the original ball or another ball. You drop from knee height, the ball falls straight down and must not touch you or your equipment. If the ball rolls out of the relief area, drop a second time. If it rolls out again, place it where the second drop first touched the ground.
Special cases: bunkers, greens and no play zones
If the ball is in a bunker, you have two choices. You may take free relief inside the bunker using the same procedure. If there is no point of complete relief there, you take maximum available relief in the bunker. Or you leave the bunker and drop back on the line behind it. That costs one penalty stroke.
On the putting green the ball is placed, not dropped. You place it at the nearest point of complete relief. If there is none on the green, that point may lie in the general area beside the green.
Sometimes the Committee declares an area a no play zone, for example to protect young turf. You may not play from there and may not even stand in the area to make a stroke. You must take relief. Playing from a no play zone is penalised.
In a penalty area there is no relief under Rule 16.1. Rule 17 applies there, and every form of relief costs one penalty stroke.
A practical example: par 4 with a building site by the fairway
You are playing a par-4 of about 340 metres. Your tee shot is stroke 1 and finishes at the edge of the fairway after 210 metres. Right there the greenkeeper has opened a drainage ditch. It is surrounded by a white line. Your ball lies inside the line.
You do not have to play the ball from the ditch. You mark the spot, lift the ball and look for the nearest point of complete relief. That is a spot on the fairway just outside the line, no nearer the flagstick. Your stance must no longer reach into the area there, and your swing must not touch it.
From that point you measure one club-length. If the driver is your longest club, that is roughly 1.10 to 1.20 metres as a rule of thumb. Within that area you drop the ball from knee height. There is no penalty. Your next stroke is stroke 2. If it reaches the green and you two-putt, you have taken four strokes, which is par.
Common mistakes and tips
The same mistakes come up again and again with ground under repair:
- Wrong measurement: what counts is the nearest point of complete relief, not the place where the ball lay.
- Dropping nearer the hole: the ball must not come to rest nearer the hole than that point.
- Dropping too far: the relief area is exactly one club-length.
- Ignoring the line: in the general area there is no relief just for the line of play. Only on the putting green can the line of putt count.
- Invalid reason: there is no relief if the interference exists only because of an unusual stance, swing or club. It is also ruled out if the stroke would be clearly unreasonable for completely different reasons, for example because the ball is deep in a thicket.
A tip for beginners: read the Local Rules before the round. They explain how ground under repair is marked and whether there are no play zones. Never play from a no play zone. And use the relief rather than hitting from a dug-up area. It protects your clubs and the course.
Ground under repair, penalty areas and obstructions compared
Beginners often mix up ground under repair with other areas. The differences are clear.
A penalty area is marked with yellow or red. Relief from a penalty area costs one penalty stroke. Ground under repair, by contrast, is free of penalty.
An obstruction is an artificial object on the course, such as a path, a building or a sprinkler head. Movable obstructions such as rakes may be removed. Immovable obstructions also give relief under Rule 16.1. Animal holes and temporary water after heavy rain belong to the abnormal course conditions as well.
Out of bounds is marked with white stakes and lies outside the course. There is no relief there. Ground under repair, by contrast, is part of the course. You may play the ball from it too, as long as the area is not a no play zone.
Try it at Golf Lounge
You can learn when to take relief from ground under repair and how to drop correctly on the Platzreife course at Golf Lounge Resort Hamburg. The theory part covers rules, etiquette and safety on the course and is linked with practice, guided by PGA coaches. As a rule it takes four to five training sessions of two hours in small groups of up to six people. The exam takes place every Saturday on site in Moorfleet.
Frequently asked questions
What does ground under repair mean in golf?
Ground under repair is an area of the course that the Committee has marked for repair or maintenance, for example a building site or dug-up earth. It is one of the abnormal course conditions. If your ball lies there, or the area interferes with your stance or swing, Rule 16.1 allows free relief.
May I play from ground under repair?
Yes, as long as the area is not marked as a no play zone. Usually it makes little sense, though, because the ground and turf there are damaged or uneven. Relief costs no penalty, so most golfers take it. In a no play zone you must take relief.
Is there a penalty for taking relief from ground under repair?
No, relief in the general area is free of penalty. The only exception is the bunker: if you want to drop outside the bunker, you add one penalty stroke. If you drop inside the bunker, relief stays penalty-free. A mistake in the procedure can also cost penalty strokes.
How far may I drop from ground under repair?
You drop within one club-length of the nearest point of complete relief. The ball must not come to rest nearer the hole than that point. A club-length is the longest club in your bag other than the putter. You drop from knee height.
Does the rule also apply on the putting green?
Yes. On the green the ball is not dropped but placed at the nearest point of complete relief. The line of putt can count there too: if ground under repair on the green intervenes on your line, you are entitled to relief. If there is no such point on the green, it lies in the area beside the green.
