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.

What are accessory dwelling units (ADUs) and how do they function?
Accessory Dwelling Units (ADUs) are secondary housing units on a single-family residential lot, offering independent living facilities. They can be attached to the primary home, such as a basement or attic conversion, or be a detached structure like a backyard cottage. ADUs typically include their own kitchen, bathroom, and sleeping area, providing a separate living space. They function as independent residences, suitable for family members, renters, or as home offices. The primary purpose is to increase housing options within existing neighborhoods, often providing flexible living arrangements while utilizing existing infrastructure. Understanding local zoning is key to their implementation.
