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.

About this service

Using an ADU as a rental involves converting a space on your property into a legal unit you can lease to tenants. This provides a steady stream of passive income, but it requires compliance with local landlord-tenant laws and ADU-specific zoning rules regarding long-term or short-term rentals. You need this service when you want to maximize your property's financial potential. Costs depend on the level of interior finish and separate utility metering. Exact pricing confirmed free on the call.
