Good News for Colorado Contractors

Colorado does not require a pre-lien preliminary notice for general contractors or subcontractors. You still must file the lien within the deadline and in the correct recording office.

Commercial vs Residential

Does the Property Type Change Your Deadline?

Colorado has the same 4-month deadline for commercial and residential. Note: special homestead protections apply on residential — verify with an attorney.

Common Mistakes

What Contractors Get Wrong in Colorado

1
Missing the 4-month deadline — Colorado courts strictly enforce it
2
Filing in the wrong county recording office
3
Not notifying the owner after filing — Colorado requires sending the owner a copy within 10 days of recording
