When we begin the job of building an accessory dwelling unit in Hillsboro, step one involves a comprehensive site assessment to understand the existing property's topography, soil conditions, and utility access points. This is crucial in a city with a density of over 4,000 people per square mile, where efficient use of space is paramount. We meticulously examine the current zoning regulations and building codes specific to Hillsboro to ensure full compliance, which can dictate everything from placement to maximum size. Our initial evaluation also includes assessing the structural integrity of any existing foundations or structures that might be incorporated into the ADU design. We consider the orientation of the site to optimize natural light and passive solar gain, contributing to energy efficiency. The proximity and accessibility of utilities—water, sewer, and electricity—are carefully documented to plan for necessary connections or upgrades. We also take into account the architectural style of the primary residence to ensure the ADU complements its aesthetic, enhancing the property's overall appeal. This thorough initial phase sets the stage for a successful and compliant ADU project. Contact us to schedule your initial site evaluation in Hillsboro.

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.
