Boundless Tiny Homes specializes in attached accessory dwelling unit construction for homeowners throughout the Madison, Wisconsin area. An attached ADU is a secondary living unit that shares one wall with the primary residence while functioning as a fully independent dwelling space.

Unlike a traditional home addition, an attached ADU includes:

A separate exterior entrance
A private kitchen
A dedicated bathroom
Independent living space
Full ADU permitting and code compliance

This type of structure allows homeowners to expand living capacity while maintaining privacy and separation between occupants.

Why Homeowners Choose an Attached ADU

Attached ADUs are especially useful for properties where lot size, setback restrictions, or zoning limitations make a detached structure difficult or impractical to build.

Because the ADU connects to the existing house, attached units can sometimes offer:

Lower construction costs compared to detached ADUs
More efficient utility integration
Faster permitting timelines in some municipalities
Better use of smaller residential lots

For many Madison-area homeowners, an attached ADU provides a practical way to create additional living space without sacrificing valuable backyard area.

Common Uses for Attached ADUs

Boundless Tiny Homes works with homeowners pursuing attached ADUs for several different reasons.

Aging Parents and In-Law Suites

An attached ADU can provide independent living space for aging parents while keeping family members close by for support and convenience.

Multigenerational Living

Families looking to create separate but connected living arrangements for adult children, relatives, or extended family often choose attached ADUs as a long-term housing solution.

Rental Income Opportunities

In walkable Madison neighborhoods, attached accessory dwelling units can serve as rental properties that offer more privacy and residential character than a standard apartment.

Smaller Lots with Limited Yard Space

For properties where setbacks or lot coverage restrictions prevent a detached structure, an attached ADU may be the only feasible path toward adding a legal second dwelling unit.

Feasibility and Property Evaluation

Before design or construction begins, Boundless Tiny Homes performs a feasibility review to determine what can realistically be built on a property.

This process evaluates:

Zoning regulations
Setback requirements
Existing structure conditions
Lot dimensions
Utility access
Municipal permitting considerations

This early-stage assessment helps homeowners understand the project’s practical limitations and possibilities before moving into design and permitting.

Most attached ADU projects completed by Boundless Tiny Homes fall within the following general parameters:

Size range: Approximately 300–700 square feet
Timeline: Approximately 4–6 months through Certificate of Occupancy
Foundation: Connected to the existing home’s structure
Separate entrance: Required for ADU designation

4. Construction and Project Management
