“We were looking for a way to live in our house for the rest of our lives and to generate at least some income in the process,” Robert Mercer and Jim Heuer wrote for the program guide of the annual Portland ADU Tour when their home was part of the lineup. “An ADU offers the possibility of caregiver lodging in the future or even a place for us to live while we rent out the main house if we get to the point where we can’t handle the stairs any longer.”
THE SOUND OF SILENCE: Internal ADUs often require that soundproofing insulation be installed between the primary dwelling and the accessory unit that’s below, above or beside it. In Portland, the building code for duplex residences requires a sound insulation rating of at least STCC45. To property owners thinking about a similar ADU setup, the duo advise: “Think about how you live in your home and how having downstairs neighbors will change what you can and can’t do with your space and what investment you are prepared to make in sound insulation.”
AN ADDED BONUS: “We are pleased that we have been able to provide more housing density on our property and still be in keeping with the historic character of our home.”
