Here is an excellent video by the Oregon DEQ about building Accessory Dwelling Units or "Granny Flats." It offers lots of great reasons to build an ADU on your property, either for rental income, relatives to live in or visit, or even to move into yourself as you rent out your main house. Propel Studio has been designing many of these projects over the past couple years and think they are a fantastic way to increase the value of your property, bring in supplemental income and creating sustainable, affordable housing stock in our wonderful Portland neighborhoods.
You can check out our previous post titled A Design Guide to Portland ADUs (Accessory Dwelling Units) for more information on this project type, frequently asked questions, and how we can help you create one on your property. https://www.propelstudio.com/accessory-dwelling-units-adu/
