Sidewalk Trip Hazard Repair: Grind, Lift or Replace?
On accessible routes, the ADA Standards allow up to 1/4 inch of vertical change, 1/4 to 1/2 inch if beveled, and anything over 1/2 inch must be fixed. Sound panels with small lips can usually be ground; settled but intact panels can be lifted; cracked, broken or root-heaved panels should be replaced.

Sidewalk Trip Hazard Repair Guide: common questions
What size lip is a trip hazard?
Under the ADA Standards for accessible routes, changes over 1/4 inch must be beveled and changes over 1/2 inch must be fixed or ramped. Many insurers flag smaller lips too.
Is grinding a trip hazard cheaper than replacing the panel?
Usually much cheaper. Grinding a sound panel often runs about $50 to $200 per spot, versus roughly $500 to $1,500 to replace a panel.
When does a sidewalk panel need to be replaced?
When it is cracked through, broken, spalled, or keeps moving because of tree roots or washout.
How long does trip hazard repair take?
Grinding is often done the same day. Replacement panels usually need a day or two before foot traffic.
