Permit steps in Terrebonne

1. Call Deschutes County Planning first. Ask what your zone is and whether the lot is in a combining zone or flood plain. The county says to research Planning and Onsite (septic) permits before you apply for a building permit.
2. Check the size. Under the 2026 Oregon Residential Specialty Code, a one-story detached accessory structure not used for sleeping or permanent cooking needs no building permit if it is 200 square feet or less and no taller than 15 feet, measured from grade to the average height of the highest roof surface. On a parcel of at least 2 acres the size limit may be increased to 400 square feet. An older county handout lists 10 feet at the highest point, so ask a plans examiner to confirm the height for your lot.
3. Ask a county plans examiner whether your building qualifies and what the wildfire rules mean for it. Plans examiners are in the Bend office Monday to Friday, 9 am to 4 pm.
4. Bring your address, the building size and height, your Hub Summary Report and, for a certified building, our engineer-stamped drawings.
5. Apply to Deschutes County Community Development. The county does the plan review and inspections.

Exempt from a building permit does not mean exempt from the rules. County zoning still applies. Separate electrical, plumbing and mechanical permits may still be required. In areas determined by the floodplain administrator, certain permit-exempt work must still be built to minimize flood damage. Our Central Oregon permit guide has more.

Snow load & certified options

The number depends on your exact address and elevation. The county points you to the state's Oregon Design Criteria Hub, a mapping tool that makes a Summary Report for your site. Ask the building department to confirm the number for your exact address.

Our certified buildings come rated for 40, 50, 60 or 80 psf snow load. We confirm the rating at order. A certified building comes with engineer-stamped drawings for the building department. In snow country we usually recommend the A-frame vertical roof because vertical panels shed snow better.

Frost, wind & other local rules

Wildfire rules. Fire-hardening rules have applied to all new accessory structures everywhere in unincorporated Deschutes County since April 1, 2026. The county's fire-hardening page separately lists non-habitable detached accessory structures with floor area less than 400 square feet and not exceeding 15 feet maximum roof height. Ask a plans examiner how the rules treat a building in that category. For anything bigger or taller, ask the plans examiner what applies before you order.

Soil. The county lists a soil bearing capacity of 1,500 psf. Give that number to whoever designs or pours your slab or footings.

Combining zones. The Landscape Management zone adds appearance and setback rules along designated roads, rivers and streams, with more design limits if the building can be seen from them. The Airport Safety zone guards against airspace obstructions, so ask about height. The Surface Mining Impact Area zone adds setbacks near mining sites. Planning can tell you if any of these cover your lot.
