Pitkin County grandfathered structures still have limits

Older cabins and long-used property setups in the Roaring Fork Valley often come with the phrase “it’s grandfathered.” The useful follow-up is: grandfathered for what?

In unincorporated Pitkin County, a use or structure that was lawfully established before the current code may be legal nonconforming. It can continue only under Chapter 9 of the Land Use Code.

Normal maintenance and repair may be allowed. Expansion, relocation, and a change of use are separate questions. For many nonconforming structures, work may proceed when it does not increase the existing nonconformity. Larger changes can require another county approval, and the path differs inside the VC and VR zone districts.

Before buying or drawing remodel plans, ask zoning staff what the county recognizes as legal nonconforming, what part of the property is nonconforming, and which Chapter 9 path applies to the proposed work. Prior approvals and the parcel’s zone district matter more than the word “grandfathered” in a listing.
