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.
Affordability in backyard homes often comes down to choosing efficient designs and standardized floor plans. By selecting a model that fits your existing utility footprint and requires minimal site excavation, you can keep your budget manageable. Exact pricing confirmed free on the call.
