Choose your city
Minnesota winters are cold and long. This means we often need to schedule foundation work and exterior framing during warmer months. Protecting the site from snow and frost is crucial. Spring and fall offer the best weather for most construction. The state has specific rules for ADUs, often varying by city. We navigate these local requirements for you. Many homes in Minneapolis and surrounding areas are older. These can have unique structural considerations. We assess your existing home to ensure a smooth build. Think about your local zoning. It dictates size and placement. We help you understand what's possible in your area.
