Do I need an engineered drawing for my shed permit in Colorado?
The short answer
Sometimes. Many Colorado jurisdictions accept our standard dimensioned drawings for accessory buildings, but larger structures, high snow-load mountain areas, and anything used as a garage or dwelling shell often require drawings with a Colorado engineer's stamp. That carries an additional fee. We walk through the exact submittal packet in our Colorado Springs shed permit guide.
Whether you need a stamped drawing comes down to your jurisdiction and the building's size and use. A plan reviewer's job is to confirm the structure will carry the local ground snow load and resist the local design wind speed. For a small storage shed, our standard drawing set usually satisfies that. For bigger spans and occupied structures, they want a Colorado-licensed engineer's seal on it.
Situations that usually require a stamp
- Mountain and foothill properties with high ground snow loads — Teller, Park, Summit, and similar areas.
- Garages and any structure with a slab foundation detail.
- Code-compliant home shells, which are reviewed as residential construction.
- Buildings well over 200 square feet, or with loft floors and wide clear spans.
- Sites with unusual wind exposure on ridgelines and open plains.
What a stamped set includes
Expect framing plans, member sizing, connection and fastener schedules, an anchoring detail for uplift, and the design loads used. Reviewers usually also want the foundation or skid detail showing how loads transfer to the ground.
Ask one question up front
Call your building department and ask: "For a [size] detached accessory building at this address, do you accept manufacturer drawings, or do you require a Colorado-stamped engineered set?" That single answer decides your paperwork and your cost.
How The Shed Yard helps
We provide standard drawings at no charge and can arrange engineered drawings when your county requires them, quoted before you commit. Because snow-load requirements change with elevation, tell us the address — not just the county — and we will point you the right direction. Talk to our team.
