Code

Washington County adopted a ruling in 1959 that required building permits in the unincorporated area.  This was at a time when the county was in the middle of developing all of the zoning for the county.  Building permits were issued and inspected using a basic safety code developed by the county.

On September 22, 1964, the county adopted a Home Rule Charter which included Ordinance #25 adopting the 1964 Uniform Building Code as the standard for the County Building Code.

In 1973, the state of Oregon introduced and passed legislation for a statewide building code program.  Key concepts included in this legislation were statewide uniformity, adoption of model codes; state building code composed of speciality codes, i.e. structural, mechanical, electrical, plumbing, boiler, elevator, local enforcement, certification of building inspectors and officials by July 1, 1977 and a training program financed by a 1 percent surcharge on all building permits.

Since that time, Oregon has adopted a number of speciality codes to enhance the safety regulations in all areas:
