What types of properties can be included in an HOA unit?

The correct answer includes a wide range of properties that can be managed or encompassed within a Homeowners Association (HOA) unit. This includes various types of residential properties such as lots, villas, townhomes, houses, or parcels.

HOAs are commonly formed in residential communities where there are shared amenities or common areas that require management and maintenance. The inclusion of diverse property types reflects the typical structure of many planned communities, which can range from single-family homes to more densely populated townhomes and villas. This variety allows for different living arrangements and community designs, fostering a closer-knit neighborhood.

The other options are too restrictive, either limiting the properties to just single-family homes, focusing solely on land without structures, or including only commercial properties, which do not align with the general nature and function of an HOA. An HOA's role is to oversee the interests of its members, which typically includes a range of residential properties, emphasizing community standards and amenities.
