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.

How much does an ADU cost in Idaho?
What are the rules for ADUs in Idaho?

Is an ADU allowed in Idaho?

Yes, ADUs are generally permitted in Idaho, but compliance with specific city zoning laws, like those in Boise City, is mandatory. Each municipality has its own set of rules. We can help confirm your property's eligibility.

What are the rules for ADUs in California?

California has enacted laws that streamline the process of building ADUs, often limiting local governments' ability to deny them. These state mandates address things like minimum lot sizes. This is specific to California, not Idaho.
