CO Questions

Why do I need a CO or Certificate of Completion?

A permit is only the start. Most building jobs end with a final inspection and a certificate from your town, city or village. Without it, the work can still show as open or unapproved on your property's record. That can cause problems when you sell or refinance.

What's the difference between a Certificate of Occupancy and a Certificate of Completion?

Both are issued by your municipality after final approval. Which one you get depends on the type of work and your town's process. We'll tell you which applies to your job.
