In Ann Arbor, the approach to accessory dwelling units (ADUs) can differ significantly between older and newer properties. Older homes may require more extensive modifications to accommodate an ADU, potentially involving structural upgrades or historical preservation considerations. Newer properties might offer more flexibility in terms of foundation, utility hookups, and modern design integration. Regardless of your home's age, an ADU provides a valuable addition for rental income or family needs. They are equipped to assess your specific property, whether historic or modern, and navigate Ann Arbor's regulations. We streamline the process, ensuring a clear path from concept to completion. Let us help you explore the possibilities for your Ann Arbor home. Call today for a no-obligation estimate.
What affects the price
Building an ADU involves several moving parts that shape your total budget. The biggest factor is whether you choose a prefabricated unit or a custom build on-site. Site preparation is also significant; if your land requires extensive grading, utility trenching, or foundation work, costs will climb. Your choice of finishes—like kitchen cabinetry, flooring, and siding materials—also shifts the bottom line. We help you navigate these variables to find a setup that fits your property.
