What Is an ADU and a Garage Conversion?
An Accessory Dwelling Unit (ADU) is a secondary housing unit on a single-family residential lot. It can be detached, attached, or converted from an existing structure, providing additional living space for family members, renters, or guests - particularly valuable in Naples where median rent is $2,057.
Garage conversions transform an unused or underused garage into livable space. This process typically involves upgrading insulation, flooring, and electrical systems to meet residential standards - essential in Naples' Mediterranean climate where temperatures typically range from 50°F in winter to 80°F in summer.
Types of ADUs: Attached, Detached, and More
We work with several types of ADUs to meet different needs and property layouts in Naples, where land is at a premium with its 3,333 residents living in a compact island community. The most common are attached and detached ADUs, each offering distinct advantages.
An attached ADU shares at least one wall with the main house. This option is often more cost-effective since it utilizes existing infrastructure like plumbing and electrical connections, important considerations in an area where 29% of residents hold master's degrees or higher.
Detached ADUs stand alone and provide more privacy. They offer flexibility in design and location but usually cost more to build due to separate utility setups.
These are particularly popular among Naples' many retirees seeking space for visiting family.
We also handle garage conversions, which transform existing garage spaces into functional living areas. This is a practical choice when adding extra square footage without expanding the building footprint in Naples' limited geographic space surrounded by canals.
