Custer accessory structures and decks can need their own permit

It is easy to picture the house as the real permit project and treat everything else as “just a shed.” In Custer County, the outbuildings get the same attention.

One accessory-structure permit covers a wide range of them. Sheds, garages, barns, and other accessory buildings all fall under it, and so do decks, porches, balconies, and structures whether they are enclosed or left open. The little projects are not a separate, lighter category.

So the conversation about a small build belongs at the start, not after the lumber arrives. Three questions answer most of it: is this kind of structure allowed in your zoning district, where on the lot can it actually sit, and what plans or drawings does the county need to see? Settling those early keeps a weekend project from stalling.

The stakes climb on the kind of ground common in the Wet Mountain Valley, lots that come with slopes, a well, a septic area, an access road, or setbacks that leave little room to spare. A detached garage or a porch can feel like an afterthought, yet it still touches drainage, fire access, the spacing between you and a neighbor, and the paperwork a future buyer’s lender will expect to see. A permit on file turns all of that from a question into a record.

The county’s building permits and applications page is the place to confirm which structures need a permit and what each one requires before you start.
