Adu company — St. Paul, MN

Last updated: September 24, 2026

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

This involves design, permitting, and the actual construction work needed to get your project across the finish line. Choosing the right partner means finding a team that handles the technical complexities of zoning and utility infrastructure so you don't have to navigate those hurdles alone.
