Do I Need A Permit?
Commercial Buildings
The answer is almost always Yes!
All construction, except one and two family dwellings and their accessory structure, are subject to the requirements of the Oregon Structural Specialty Code. The only exemptions are listed in Sec.106. and they are as follows:
Unless otherwise exempted, separate plumbing, electrical, and mechanical permits will be required for the above items where appropriate.
*Exemption from the permit requirements of this code shall not be deemed as to grant authorization for work done in violation of the provisions of the Oregon Structural Specialty Code or any other laws or ordinances of the county.*
Do I need an Architect for Commercial Buildings?
In general, the erection, enlargement, or alteration of any commercial building where the resulting building has a ground area more than 4000 square ft, or is more than 20 feet in height from the top surface of the lowest floor to the highest interior overhead finish, requires plans prepared and signed by an engineer or architect licensed by the State of Oregon.
The Plans examiner may require engineering calculations for any structure to demonstrate compliance with the structural provisions of the code if the construction does not comply with the “Conventional Construction” provisions of Sec.2517.
Persons wishing to construct agricultural buildings must make application for exemption through Deschutes County Community Development Department, and are exempt only if they comply with ORS.455.315. Non-structural alterations or repairs are exempt from the above requirements.
Residential Buildings - One and Two Family Dwellings
It is not the intent of the dwelling code to require permits for minor repairs, general maintenance or minor improvements, when such work is done on a one or two family residence or accessory building.
The following items, associated with one and two family dwellings, which do not encroach on subsurface disposal systems, setbacks or into required yards, are exempt from permits and fees:
See ORS 455.320 for exemptions of room sizes, ceiling heights and maintenance of specific temperature levels
All other construction for one and two family dwellings requires permits and fees.
