Accessory dwelling unit grants — Hillsboro, OR
Last updated: September 24, 2026
What affects the price
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.
About this service
Grants are occasional funding programs offered by local or state governments to help homeowners cover a portion of their construction costs. These are usually limited to specific regions or income levels and come with strict eligibility requirements. You should look into these if you are in the early planning stages and want to see if your project qualifies for public financial assistance. Keeping an eye on local housing authority websites is the best way to find current opportunities. Exact pricing confirmed free on the call.
