Accessory or Auxiliary Dwelling Units (ADU) are becoming very popular in the Portland, OR area. With the ability to add more room for extended family, provide an aging-in-place option, or earn extra income as a stand alone rental property, ADUs can come in all shapes and sizes.
Depending on city or county residential codes, a basement or attic can become an ADU with proper modifications. An ADU can also be a new addition to an existing house or a detached structured located elsewhere on the property. Essentially, these are standalone areas that can have as much – or as little – access to the main home as desired.
This means each ADU should have it’s own entrance and contain a living, sleeping, kitchen and bathroom areas. ADUs can still have all the creature comforts of home – just on a smaller scale.
Wondering if an ADU is right for you? Here are some things that Oregon Builders & Restoration will investigate for you before the first shovel of dirt is turned:
- Are they allowed in your neighborhood?
- Will it be inside/attached/free-standing?
- What is the size of the ADU?
- Is your property large enough to support an ADU?
- Is your property properly zoned for an income property?
- What are the property setbacks and will that leave enough room for an ADU?
Once the codes and requirements are met and the permits secured, Oregon Builders & Restoration can begin construction on the ADU.
