In Hillsboro, Oregon, with a population of 107,730 and a density of 4,168 people per square mile, the one question worth asking any provider before hiring for accessory dwelling unit construction is about their specific experience navigating Washington County's and Hillsboro's unique ADU ordinances.

Building an ADU is a custom project, so costs vary based on your specific choices. Site conditions are the biggest factor; if your land requires significant grading, utility extensions, or foundation work, those expenses add up quickly. Choosing high-end finishes, custom cabinetry, or complex roof lines will also push the budget higher compared to a standard design. Prefabricated units often offer predictable costs, while custom site-built structures allow for more flexibility but can be harder to estimate upfront. Exact pricing confirmed free on the call.
A modular ADU is a home built in a controlled factory setting and then transported to your property to be placed on a permanent foundation. This method is often faster than traditional stick-built construction because the structure is built off-site while your foundation is prepared. You should choose this if you want a quicker build timeline and less disruption to your backyard. Factors like site accessibility for cranes impact the final price.
