Fees & System Development Charges

Project valuation (cost of labor + materials) will determine the fees. Sub-permits such as commercial mechanical, fire sprinkler, and fire alarm are calculated based on the valuation for the individual scope of work. The valuation should includes all materials, parts, and labor. For an estimate of the building permit fee, see current fee schedules.

The plumbing permit fee includes the total number of plumbing fixtures capped, added, or moved, and installation of any linear length of pipe. This fee schedule is for both commercial and residential plumbing projects.  The minimum fee covers permitting and inspection costs.

The residential mechanical permit fee includes the number of new mechanical fixtures (exhaust fans, fireplaces, etc). For a quick mechanical permit fee reference, see Building Division Fee Schedule.

Rates for the TDT are set by Washington County Land Use & Transportation and are dependent on intended use of the property. Uses that result in more public road trips will pay a higher rate because the more impact a business has on the roads the more it costs to maintain.  For changes in use, fees will be based on the difference between the previous and proposed uses. To see the most recent Washington County TDT Rate Schedule, please visit their webpage. For questions regarding specific TDT fees for your project, please contact the Engineering Division at 503-692-2010.

Rates for sewer SDCs are set in coordination with Clean Water Services (CWS).  Fees are assessed on the plumbing fixtures you add to your project, and fixtures that generate more waste into the system have a higher rate.

If your project requires a new or upsized water meter, an SDC will apply for the cost of the meter, plus installation.  For the current water meter SDC rates, please see the document attached below. When a meter is upsized, credit will be given for the existing water meter. This fees is used for maintaining our clean water system through the water system fund.

This fee is charged when a water meter is to be installed or switched and is based on the size of the meter. This covers the cost of the meter installation.

These rates are assessed based on a flat rate for each new dwelling unit for single-family and multi-family residential development. Non-residential rates are determined using development categories and any new square footage or change of use.

The School CET rates are set by the individual school district in which your project falls and is based on new square footage for both residential and non-residential projects. Tualatin stretches across four different school districts:  Tigard-Tualatin, West Linn-Wilsonville, Sherwood, and Lake Oswego. Please see the School District CET rate sheet for the most current rates.

These rates are set in coordination with Clean Water Services (CWS). Any time you add any additional impervious surface area to a project, stormwater SDCs apply (based on square footage of impervious surface area). Additional impervious surface examples are additions to buildings, large concrete pads, parking lots, covered areas, etc. The extra water runoff is a larger impact on the stormwater system.
