Thinking about adding an Accessory Dwelling Unit (ADU) to your Seattle home? It's a smart way to increase your property's value and create flexible living space in this dynamic city. As Seattle continues to grow, particularly in neighborhoods like Ballard and Capitol Hill, the demand for diverse housing options is evident. An ADU can provide a valuable rental income stream, accommodate extended family, or offer a private workspace. Factors such as your lot size, existing structure placement, and neighborhood design standards will all influence what you can build. We're here to simplify that process for you. Don't let uncertainty hold you back from this excellent opportunity. Call us today for a free estimate and let's discuss your ADU potential.

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.
