Portland Oregon is in the seismic category three. This means a masonry chimney must be built with reinforcement. Re-bar, rings and chimney straps anchor a masonry fireplace and chimney structure to the building. This is the code because if we were to have an earthquake the chimney would not sheer, crack or fall onto the house among other things. In this old Portland historical district many customers are interested in protecting their priceless homes. At Portland fireplace and chimney we strongly encourage and educate our homeowners to repair their chimney to seismic specifications.
