Toensing Construction is a licensed and insured Rhode Island general contractor providing ADU construction for homeowners looking to add flexible living space, support multigenerational housing, or create a well-designed in-law suite. They build attached and detached accessory dwelling units, garage conversions, basement apartments, and over-garage living spaces tailored to the property, the family, and local permitting requirements.

For homeowners planning an ADU in Rhode Island, Toensing Construction can help evaluate the best approach based on lot conditions, budget, and long-term goals. Whether the project involves a backyard cottage, a private in-law apartment, or a conversion of existing space, they focus on building practical, durable spaces that integrate naturally with the existing home.

Their custom ADU construction services cover homeowners across Rhode Island and include:

1. Detached ADUs and backyard cottages
2. Attached ADUs and home additions
3. In-law suites
4. Garage conversions
5. Basement apartment conversions
6. Over-garage apartments
7. Secondary living spaces for guests, caregivers, or adult children

Every project begins with the property itself. Toensing Construction looks at available space, access, utility connections, privacy, parking, layout, and how the new ADU will function on a day-to-day basis.

Types of ADUs Toensing Construction Builds

Detached ADUs are separate structures on the same property as the main house. This is a common choice for homeowners who want privacy and independence in a dedicated secondary dwelling.

Attached ADUs connect to the primary home through an addition or reconfiguration. This format is frequently used for in-law suites and family housing where closer access is a priority.

Garage conversion ADUs can be an efficient way to create an accessory dwelling unit using existing square footage. Toensing Construction evaluates structural condition, layout, access, insulation, and utility needs to determine feasibility before moving forward.

Basement ADUs can create self-contained living space while making better use of the home's existing footprint. Key considerations include entrance options, ceiling height, natural light, and code-related requirements.

Over-garage apartments add living space while preserving yard area and can blend well with the existing home's appearance.

Homeowners in Rhode Island commonly build ADUs for a range of reasons, including in-law housing, multigenerational living, aging in place, guest accommodations, and flexible space for adult children or caregivers.

When helping homeowners plan their project, Toensing Construction works through considerations such as:

1. Detached vs. attached ADU options
2. In-law suite design priorities
3. Garage and basement conversion feasibility
4. Site planning and privacy
5. Utility access and service upgrades
6. Long-term family use and resale value
7. Construction scope, finish level, and budget priorities

The ADU Construction Process

Toensing Construction follows a structured process from initial consultation through project completion:

1. Initial Consultation — They start by learning about the property, the homeowner's goals, and how the space will be used. This helps determine whether a detached ADU, in-law suite, garage conversion, or another format is the right fit.
2. Site Review and Feasibility — The property layout, access, existing structure, and practical constraints are assessed before design work begins.
3. Design and Planning — The project moves from concept to a buildable plan, with coordination of the details needed for a functional living space.
4. Permitting and Local Coordination — ADU projects often involve zoning, code, and permitting requirements that vary by municipality. Toensing Construction helps guide the project through that process.
5. Construction — Once approved, they manage the construction process from start to finish, with attention to schedule, workmanship, and quality control.
6. Final Walkthrough — Before closeout, the completed project is reviewed with the homeowner to confirm the ADU meets the expected standard.
