Repair and rehabilitation of a structure are processes that can restore a building to its original condition or improve its strength and performance.

Repair

A process that restores a structure to its previous condition, usually without improving its strength. Repairs are often the least time-consuming and resource-intensive option.

Rehabilitation

A process that restores a structure to its original design strength, or as close to it as possible. Rehabilitation can include repairs, retrofitting, and strengthening to improve a structure's performance and reduce its vulnerability to damage.

Retrofitting

A process that improves a structure's strength to meet current safety codes and standards. Retrofitting is often the most resource-intensive and planning-intensive option.
