Building Division FAQ

The property owner is ultimately responsible for obtaining all permits for work occurring on their property.  The property owner can designate someone to apply on their behalf such as contractor, tenant, engineer, architect, etc.  

Permits are required for any new construction, alterations and additions to existing structures, including structural, plumbing, mechanical, and electrical work. However, there are some exceptions to the structural requirements. If you aren’t sure you need a permit, call the City of Tualatin Building Division, (503) 691-3044.

Commercial or Multi-Family Buildings

You are required to hire an architect or engineer according to the following State laws. Please call one of our building inspectors or plans examiners if you have any questions.

Residential Single-Family Projects

An architect or engineer is required only when special structural conditions apply, such as seismic bracing requirements and large window expanses, decks and patio covers over ten (10) feet in height, special soils conditions and sloping sites, and other unusual structural elements like extensive cantilevers.

Work can begin as soon as the permit is issued. The permit must be on the job site while work is in progress and when the inspector is present. If you have submitted plans, one set of plans stamped “Approved” will be returned to you. These approved plans, along with the permit, must be on the job site while work is in progress and also when the inspector is present.

Permits are not required for porches and decks, where the floor or deck is not more than 30″ above adjacent grade at any point and where in the case of a covered porch, the covered portion of the porch does not come closer than 3′ to property lines. 

A permit is required if it involves the replacement of joists, beams, railings, or stairs. A permit is not necessary if only the decking (top) is being replaced. 

Oregon law requires plumbing permits for water heaters because of potential safety hazards such as fire, electric shock, or explosion.

Your permit expires if work does not start within 180 days of the date of issue. Once you have started working, your permit expires if work is suspended or abandoned for 180 days or more. If you cannot work within a 180 day period and do not wish to abandon the project, you may submit an extension request form for an additional 180 day period.

You may contact a plans examiner or inspector by calling the Building Division at (503) 691-3044.
