Crook County, Oregon Building Permit Guide

The Crook County Building Department, part of Community Development in the county courthouse, issues all building permits in Crook County, including inside Prineville, the county’s only city. Contractors and owners can apply, pay and book inspections on Oregon ePermitting, though inspection cards are still picked up at the office. Under the fiscal 2026–27 schedule a new house valued at $150,000 carries a $976.00 structural permit fee, plus 75 percent plan review, the 12 percent state surcharge and a county code compliance fee.

What requires a building permit in Crook County?

The department reviews and inspects work under the state building codes and Title 15 of the Crook County Code, Buildings and Construction. Its residential forms cover one- and two-family dwellings, manufactured homes, accessory structures, remodels and additions, demolition and removal, residential solar and the separate electrical, mechanical and plumbing permits; the fee schedule adds re-roofing “when required,” fire sprinkler systems, floodplain development review and changes of occupancy.

The exemptions come from sections R105.2 and R101.2.2 of the 2026 Oregon Residential Specialty Code, whose chapter 1 is mandatory from October 1, 2026. Pool-barrier fences always need a permit. A shed under the exemption can still need county planning approval: the planning fee list includes a $100 site plan review for an accessory structure under 200 sq ft with no plumbing, electrical or mechanical work.

What the county decides and what the state holds

The county adopts its fee schedule each fiscal year and adds charges of its own on top of the state-based permit fees: a code compliance fee that pays for code enforcement and an advanced planning fee for long-range planning on larger projects. It also sets local installation details in its Applicable Regulations and Minimum Criteria sheet, such as an 18-inch frost depth. The codes, trade licensing and the 12 percent surcharge come from the state.

Crook County building department: who handles permitting

The Building Codes Division’s Local Building Department Directory lists Crook County for all building permits in Prineville, Powell Butte, Paulina, Post and the rest of the county. There is no city building department, so the county also issues the trade permits inside Prineville.

The county warns that fraudulent emails asking for wire transfers have come from addresses ending in @usa.com, and that only messages from @crookcountyor.gov or @accela.com addresses are genuine.

Permit types and approvals before filing

Residential permits

The dwelling and manufactured home applications are built to include everything needed to start, while other projects add separate discipline applications. A residential submittal includes the county applications, the zoning, moisture and lighting acknowledgements, the HVAC and whole-house ventilation checklist, an initial flood elevation certificate, the property owner statement, a complete plan set and a copy of the land use approval. Electronic plans are accepted as one PDF per discipline; uploads of single plan pages are rejected. In subdivisions that require fire sprinklers, the sprinkler plans and calculations come with the house application. The forms list also includes a residential dwelling contractor verification form.

Commercial permits

Commercial work has its own application page. A fire and life safety review at 40 percent of the structural fee is required on every structure over 4,000 sq ft and on any project the building official names. A complex or large project can book a pre-application consultation at $197 an hour with a two-hour minimum; phased projects pay $330 plus 10 percent of the total permit fee, capped at $1,500 a phase, and deferred submittals 65 percent of the fee on the deferred part, at least $315.

For tenant improvements and new commercial builds, Alliance handles commercial building permits through issuance. More on this: commercial building permits explained.

What comes before the building permit

• Land use: outside Prineville the county Planning Department issues the land use approval; applications go by email, in person or by mail. A residential site plan review is $1,124, an accessory structure review $305 and an accessory dwelling unit $1,286, each plus a code compliance fee ($189 on planning fees of $1,001 to $5,000).
• Septic: the county On-Site program, working under DEQ authority, needs a site evaluation ($889) with at least three test holes before a construction permit ($1,098 for a standard system, more for capping fill, pressure distribution or sand filters); a DEQ surcharge is added, and the county may double a septic fee if work starts before the permit.
• Parks district: a dwelling or manufactured home inside the Parks and Recreation District pays that district’s fee before the permit issues.
• Floodplain: an initial flood elevation certificate is part of a residential submittal where it applies.

Building permit fees

The county’s fee schedule for fiscal year 2026–27 took effect July 1, 2026. Structural fees use the ICC valuation table current on April 1 each year.

State surcharge, in the county’s words: the 12% state surcharge is “Required to be added to Building Permit Fees as per the State of Oregon, ORS 455.210(4) & (5) and 455.220(1),” and the mechanical, plumbing and electrical sections each say their permits are “subject to a State Surcharge of 12% of the total permit fee.” Residential demolition ($110) is marked as not subject to it.

Worked example: a new house valued at $150,000 is in the top band: $763.50 plus 50 × $4.25 = $976.00. Plan review adds $732.00, the 12 percent surcharge on the permit fee $117.12 and the code compliance fee $270.00, for $2,095.12; the advanced planning fee is waived below $300,000, and trade permits, land use and septic fees are extra.

Trade permits and who may pull them

All electrical, mechanical and plumbing permits in the county, Prineville included, come from the Building Department, each on its own application. Plumbing plan review, where needed, is 30 percent of the plumbing fee, and mechanical plan review 75 percent; residential mechanical work is priced per appliance, such as $20 for a heat pump or furnace up to 100,000 BTU and $22 for a wood or pellet stove, over the $126 minimum.

• Owners: the county’s answer to “Can I do my own work?” is “In most cases, yes.” State law sets the limits: ORS 479.540 for owners wiring residential or farm property of their own or their immediate family that is not for sale, exchange, lease or rent, and ORS 447.060 for plumbing not done for hire.
• Contractors: a contractor needs a Construction Contractors Board license, and electricians and plumbers working for hire need their state licenses. If the contractor changes, the county must be told in writing, and a new permit may be needed.
• Owner-builders: the property owner statement on the residential forms list is the county’s form for owners; ORS 701.325 requires anyone exempt from CCB licensing to state the reason when applying.

How to apply

Review, corrections and what causes delay

Review does not start until the plan review fee is paid, and individual page uploads are rejected. Extra review caused by changes is $132 an hour with a half-hour minimum, and a change after approval goes on the revision application. Applications and permits stay active for 180 days, each approved inspection adds another 180, and the county emails or mails a notice before expiry; an extension request can be filed but is not guaranteed.

Inspections

Unless you ask for a later date, inspections happen the next business day between 8 a.m. and 4 p.m. Book through the ePermitting app or website; a same-day inspection is possible only when it is booked there before 7 a.m., and inspections booked by phone with the office cannot be same-day. Voicemail requests are not guaranteed. Because much of the county has no reliable cell coverage, the inspection cards, job location card and approved, legible color plans must be on site; without them an inspection can be marked not ready or denied, with added fees.

The county’s minimum criteria sheet sets the test pressures inspectors expect: at least 5 pounds of air for 15 minutes on waste and vent piping, 50 pounds for 15 minutes on water lines and 10 pounds for 15 minutes on gas piping. Water service lines go at least 30 inches deep, gas lines at least 18 inches with yellow tracer wire, and sewer lines carry green tracer wire.

Code editions and flood maps

The 2026 Oregon Residential Specialty Code applies to new applications, with its construction chapters optional against the 2023 edition until April 1, 2027; commercial work is under the 2025 structural and mechanical codes, and the 2026 electrical and plumbing codes took effect October 1, 2026. The county’s May 2026 criteria sheet still lists the earlier residential, plumbing and electrical editions. Site wind and snow loads come from the Oregon Design Criteria Hub or the ASCE hazard tool. Both Crook County and Prineville take part in the National Flood Insurance Program (FEMA Community Status Book), with flood maps dated February 2, 2012.

Oregon’s building code and its exemptions are the same in Crook County as everywhere in the state, and an exemption from the building permit is not an exemption from zoning, land use or a trade permit. Site snow, wind and seismic values come from the state’s Oregon Design Criteria Hub. How Oregon’s statewide code works
