Is the bedroom up to code in your short-term rental?

Housing in Portland is diverse in age and construction type. Many bedrooms in older homes were approved to be used as sleeping rooms based on the building code requirements at that time.

Some older homes have bedrooms that were never approved as legal sleeping rooms. Examples might include attics, basements, garages, porches, patios, or other accessory buildings.

If you don't know if a bedroom was legally converted in the past, research this before applying for a short-term rental permit. If the bedroom wasn't legally created with a permit, this will come up during a property inspection. This can be a costly and time-consuming process.
