Even where no exterior work is proposed, the building owner may be required to make improvements to the public right of way. If the Office of Transportation determines that the existing right of way conditions are substandard, and the value of the proposed alterations to the building exceeds 35% of the assessed value of all existing improvements on the site, Transportation may require that you dedicate part of your property to construct street improvements. With a dedication, private property is legally converted to public right of way so as to improve a sidewalk, bike lane, etc. The value of required fire, life safety, accessibility and seismic upgrades may be subtracted from the total permit value for purposes of determining the 35% threshold.
Transportation staff at (503) 823-7002 can give you information about the status of the right of way at any location.
