House conversions to Live/Work usually don't trigger Bureau of Transportation System Development Charges unless the house is larger than 3,000 square feet in floor area. For more information on Transportation SDCs call (503) 823-7002.
BES charges a Sanitary SDC for commercial projects whenever a development permit includes the addition of one or more new plumbing fixtures. (A new "fixture" is a sink, toilet, dishwasher, floor drain, etc.).
Different plumbing fixtures are charged at different rates. Call BES at (503) 823-7761 for more information.
For the Water Bureau, an SDC is based on the size of meter installed. If your new project will include the addition of plumbing fixtures, a larger meter size may be required and an SDC charged. Portland Water Bureau staff is available to answer your SDC questions at (503) 823-7368 or view more information online.
