The process of Designing and Building an ADU in Portland

When you work with Refresh, your ADU remodeling consultant will be your guide throughout your ADU construction in Portland. First, you'll want to define what your plans are for your ADU. Will it be to house family and friends, or will it serve as an AirBnB or rental property? You might browse some local Portland ADU examples to get inspiration. How much space do you have for your ADU? The average ADU size is between 600 to 1200 square feet, but that depends on the size of your property.

Next, it's time to design your space. Your Refresh ADU Consultant will work together with you to come up with an ADU design specific to Portland that complements your property and meets local regulation guidelines. ADU plans in Portland vary depending on the size of the property and the purpose of the dwelling. Once plans are drawn up and you are happy with those, your ADU Consultant will come back to you with a fixed quote. To get your personalised quote, book your free consultation now!

Types of ADUs

In most circumstances, homeowners will build ADUs as an accessory apartment to accommodate friends, family, guests or tenants. Primarily, you will need to decide whether or not you want it to be attached to your house or detached. For some, a home extension is the best option. For others, particularly those who want more space and privacy, a detached unit is the best solution. Many homeowners choose to renovate their garages into ADU units - either as a complete conversion or by adding a second story living space above the garage.
