FIRST THINGS FIRST:
What's An ADU?
An ADU — Accessory Dwelling Unit — is a fully independent living space on your property with its own entrance, kitchen, and bathroom. ADUs deliver flexibility: they increase property value, accommodate aging loved ones, or generate rental income.
ADU Solutions Designed for Real Properties
No two properties, or families are exactly alike. That’s why have multiple ADU types, each designed to address common site conditions, zoning constraints, and homeowner goals across Dane County Wisconsin.

Detached ADUs
A detached ADU is a fully independent living unit located separately from the primary residence. This option is often ideal for larger lots or homeowners seeking a clear separation between the main home and the ADU. Detached ADUs provide flexibility for long-term family living, guests, or rental use while maintaining privacy for both spaces.

Attached ADUs
An attached ADU shares a wall or structural connection with the primary residence. This approach is commonly used when zoning, lot size, or site conditions favor expansion rather than a separate structure. Attached ADUs can offer efficient construction and convenient access while still functioning as a fully independent living unit.

Garages ADUs
A garage ADU is built above a new garage, or replaces an existing garage structure. This configuration is frequently used to meet zoning and setback requirements while preserving parking and access. Garage ADUs are a practical solution for properties where maximizing vertical space is key.

Pool Houses
Whether you need extra storage space or simply want to enhance your poolside ambiance, a pool house is the perfect way to infuse enjoyment and practicality into your outdoor space. If you’re considering taking your pool to the next level, learn more about the benefits of building a pool house, brought to you by your expert pool house builder in Madison, WI.

Offices
We understand the importance of creating a comfortable and productive workspace within your home, and our commitment to quality and affordability ensures that our ADU offices are the ideal choice for those seeking a convenient and private office solution. Trust Boundless Tiny Homes to transform your work-from-home experience into one of comfort and efficiency.
