ADU Types and Configurations
The company works with several ADU configurations, with the appropriate type determined in part by the client's local municipality. Each town's Planning and Zoning department has its own rules regarding what is permitted, and ADU Builders CT LLC conducts a feasibility study as part of their complimentary design consultation to identify any limitations early in the process.
Detached ADU (Stand-Alone)
A detached ADU is a standalone dwelling unit built on the same property as the primary residence, typically in the backyard or side yard. It includes its own entrance, kitchen, and bathroom, offering a fully independent and private living space with no shared walls.
Attached ADU
An attached ADU is physically connected to the primary home and shares at least one common wall with the main dwelling. This configuration blends with the existing home's footprint and can be a practical option for flexible living arrangements with shared utility access.
Above-Garage ADU (Carriage House)
This type of ADU is built above an existing or newly constructed garage. Sometimes referred to as a carriage house, it functions as a fully independent living unit and can be a good solution for smaller lots where ground-level space is limited.
Basement ADU
A basement ADU — also known as a basement apartment, in-law unit, or secondary suite — is a self-contained living space created within the existing basement of a single-family home. This type of conversion can add functional living space while also increasing a home's resale value.
Attic ADU
An attic ADU involves converting existing, unused attic space into a habitable living area. Because it works within the home's existing footprint, this type of internal conversion can sometimes avoid certain zoning or lot size restrictions. Features like vaulted ceilings, skylights, or custom built-ins are possible depending on the structure.
Pool House ADU
A pool house ADU meets the standard requirements of an accessory dwelling unit — including a full kitchen, bathroom, and sleeping area — making it a fully livable space. Its proximity to a pool also makes it suitable for outdoor entertaining and leisure use.
General Remodeling and Custom Build Services
Beyond ADU construction, ADU Builders CT LLC also handles general home remodeling projects. Their services include kitchen and bathroom renovations, basement and attic conversions, and full home renovations. The company works with skilled tradespeople and sources materials for finish carpentry, flooring, lighting, plumbing, and hardscape features.
Custom plans are available across multiple ADU types, allowing clients to tailor the design to their specific needs and property conditions. The company's project delivery process has been refined over decades and is structured to keep clients informed at each stage of construction.
ADU Builders CT LLC is based in Westport, CT and serves clients throughout Connecticut.
