What happens if I damage a green during my round?

There's no automatic penalty under the Rules if you accidentally damage a green, but deliberately causing serious damage counts as serious misconduct and can get you disqualified. A Committee can also adopt a Code of Conduct that adds a one-stroke or general penalty for course damage.

What the Rules actually say

Rule 1.2a expects players to take good care of the course — that means repairing ball marks, replacing divots, and not causing unnecessary damage. But here's the key: the Rules themselves don't attach a penalty for failing to do this. The only built-in sanction is disqualification for serious misconduct, and the official interpretation spells out that deliberately causing serious damage to a putting green qualifies. So if you spike a green in frustration or gouge it with your putter, the Committee can DQ you. If you accidentally drag your bag across the fringe or leave a deep pitch mark you forgot to fix, that's not a Rules penalty — it's just bad etiquette.

When a Code of Conduct changes things

Rule 1.2b lets a Committee adopt a Code of Conduct as a Local Rule. If they do, they can attach penalties for breaching it — typically a one-stroke penalty or the general penalty (two strokes in stroke play, loss of hole in match play). Many tournaments and clubs now use this to penalize things like failing to repair ball marks or damaging greens in anger. Always check the notice board or the "Notice to Players" on the first tee. If a Code of Conduct is in effect, the penalties are real and enforceable, even though the base Rules don't mandate them.

What to do if you damage the green

Fix it. Repair your ball mark properly (use a repair tool, push the edges toward the center, don't lift up), smooth any spike marks if local rules allow, and if you've done something worse — like a divot on the putting surface — tell a referee or the Committee right away. Honesty and quick action matter more than the damage itself when the Committee decides whether it's serious misconduct.

Exceptions that change the answer

• A Committee has adopted a Code of Conduct under Rule 1.2b → Breaching its standards (e.g., failing to repair damage, damaging the green in anger) can carry a one-stroke penalty or the general penalty, and serious breaches can still lead to disqualification.
• The damage is deliberate and serious → It's classified as serious misconduct under Interpretation 1.2a/1, and the Committee may disqualify you even without a Code of Conduct.

Frequently asked questions

Do I get a penalty stroke for accidentally damaging the green?

No. The Rules of Golf don't impose a penalty for accidental damage. Only deliberate, serious damage counts as serious misconduct, which can lead to disqualification.

What counts as serious misconduct on a green?

Deliberately causing serious damage — like stabbing the green with a putter, carving initials, or aggressively twisting spikes — is the classic example. The Committee judges based on all circumstances.

Can my club give me a penalty for not fixing a ball mark?

Yes, if they've adopted a Code of Conduct under Rule 1.2b that includes that standard. Many clubs now do. Check the Local Rules posted on the first tee.

What if I see someone else damaging the green?

If it's deliberate and serious, report it to the Committee. They decide whether it's serious misconduct. You don't call the penalty yourself — the Committee does.

Does repairing spike marks on the green count as damage?

No. Since 2019, you're allowed to repair spike marks and other shoe damage on the putting green without penalty (Rule 13.1c). That's encouraged, not penalized.
