Corvallis is the seat of Benton County and home to Oregon State University at about 61,000 residents, a Willamette Valley university city. Building permits are issued by Development Services, a division of the Community Development Department that serves as the city’s one-stop shop for permit review, issuance and inspection at 501 Southwest Madison Avenue.
This guide covers Development Services and how to reach it, the uniform statewide code, the university and land-use context, and how fees and inspections work.
This guide covers work inside the City of Corvallis limits. Benton County and neighbouring Philomath are separate authorities.
Corvallis runs a one-stop Development Services shop for building permits and inspections, which also answers zoning, site-engineering, grading and erosion-control questions. It administers the uniform state code, issues the electrical, plumbing and mechanical permits, and processes floodplain-development and other permits alongside construction permits; most land-use applications go to the city’s Planning Division. Apply online at corvallispermits.com, and pull Cascadia seismic values from the state Design Criteria Hub.

The Oregon Residential Specialty Code (ORSC) governs one- and two-family dwellings and townhouses and their accessory structures; the Oregon Structural Specialty Code (OSSC) governs commercial buildings, apartments of three or more units and everything outside the residential scope. Alongside them sit the mechanical, plumbing, electrical and energy specialty codes, and the Oregon Fire Code is adopted by the State Fire Marshal. In Corvallis, Development Services administers the state code alongside zoning, floodplain and site-engineering review in one coordinated office.
Oregon’s building code and its exemptions are the same in Corvallis 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
Who handles permitting in Corvallis?

Development Services reviews and issues building, electrical, plumbing and mechanical permits and performs inspections, and it also handles zoning inquiries, site engineering, floodplain development, and grading and erosion control. Every building permit needs plan review: the city allows two business days for a completeness check, then targets two weeks of review for one- and two-family projects and three weeks for multi-family and commercial projects, or two business days for projects that qualify for Rapid Review. Oregon State University drives strong student-housing and institutional demand.
The technical code is the uniform state code; what Corvallis adds is coordinated land use, the fee schedule and the inspection process.
In 2025, building permits issued in Corvallis authorized 401 new privately owned housing units, 26 of them single-family homes, according to the U.S. Census Bureau Building Permits Survey.

Residential permits
Residential work spans neighbourhoods, infill, accessory dwelling units and student-housing conversions. Re-roofs beyond the exempt scope, solar and EV chargers need permits, seismic detailing applies broadly, and every contractor needs a current CCB licence, apart from casual work under $1,000 and owners working on their own property.
Commercial permits
Commercial work runs from university-adjacent and downtown development to retail and institutional projects, all subject to plan review, land use, and the CCB licence requirement, with electrical and plumbing work generally done by state-licensed trades.
Contractors need a current Construction Contractors Board licence with the right endorsement for a job of any size; the exceptions are casual work under $1,000 by someone who does not advertise as a contractor, and owners working on their own property who are not building to sell.

Corvallis permit costs and fees
Budget the city building permit and plan-review fees, separate trade permits, system development charges, the school and affordable-housing construction excise taxes, the 12 percent state surcharge, and any land-use or design review a parcel triggers; the floodplain development permit itself carries no fee. Fees follow Oregon’s statewide valuation method with the city schedule, and the city puts building permit and plan review fees at typically 1 to 2 percent of a project’s cost.
| Fee component | How it works |
|---|---|
| Building permit | Based on Oregon’s statewide valuation method; the schedule is set locally |
| Plan review | Equal to the building permit fee and paid when you apply; the city schedule adds Land Development Code review (67 percent of plan review) and a service enhancement fee (33 percent of plan review), and a fire and life safety review, where required, equal to the permit fee |
| Trade permits | Separate electrical, plumbing and mechanical fees |
| State surcharge | A statewide percentage surcharge added to permit fees |
| Land-use review | Zoning, design or land-use review where the project triggers it |
| Re-inspections and revisions | Additional fees for failed inspections, revisions and expired permits |

Oregon fixes the method rather than the price: new construction is valued with the ICC building valuation data under OAR 918-050-0100, Corvallis applies its own schedule, and a 12 percent state surcharge is added to every permit fee. How Oregon permit fees are set

Electricians and plumbers are licensed by the state, though an owner may do electrical work on their own home and plumbing work that is not for hire. An electrical permit is needed for new or altered wiring; like-for-like repairs of outlets, switches and fixtures, and bulb, fuse and small-appliance swaps, are exempt.

Philomath and unincorporated ground are separate authorities.

Cascadia design applies broadly in the valley.
Oregon requires it for almost any paid job; the exceptions are casual work under $1,000 and owners working on their own property.
An owner may do electrical work on their own home and plumbing work not done for hire; otherwise the installer needs the state trade licence.

An Oregon building permit expires if work does not start within 180 days of issue or stops for 180 days; the building official can extend it in writing, 180 days at a time. Oregon’s statewide code rules
Inspections in Corvallis
Standard checkpoints include footing and foundation, under-floor and slab, framing, rough-in electrical, plumbing and mechanical, insulation and energy, fire systems on commercial work, and final, with occupancy approval before use. Floodplain and infill work adds elevation and site verification.
Many Oregon jurisdictions take inspection requests online, several through the state ePermitting system; confirm the method Development Services uses and give the notice it asks for.
Do not cover work before the required inspection has been approved. Keep the issued permit, the approved plans, the seismic and energy documentation, product listings and your correction responses available on site.
