What Exactly is an Accessory Dwelling Unit (ADU)?

An Accessory Dwelling Unit (ADU), often referred to as a 'granny flat,' 'in-law suite,' or 'backyard cottage,' is a secondary housing unit on a single-family residential lot. ADUs are distinct from the primary dwelling and can be:

  • - Detached: A completely separate structure, like a small guesthouse or garage conversion, in the backyard.
  • - Attached: A portion of the existing primary home, such as a converted basement or an addition with a separate entrance.
  • - Internal: A self-contained unit within the existing structure, like a remodeled attic or basement unit.

The key characteristic of an ADU is that it provides independent living facilities, including sleeping, cooking, and bathing, while being on the same lot as another single-family home. For Riverland Terrace homeowners, an ADU can offer significant benefits.

The Advantages of ADUs for Riverland Terrace Residents

ADUs offer a multitude of advantages, making them an attractive option for homeowners and the broader community:

**For Homeowners:

  • - Rental Income: Generate additional income by renting out the ADU. This can help offset mortgage payments or provide extra cash flow.

Understanding ADU Regulations in Charleston County (Including Riverland Terrace)

Charleston County, which includes Riverland Terrace, has specific regulations governing the creation of Accessory Dwelling Units. These regulations are designed to ensure that ADUs are built safely, do not negatively impact surrounding properties, and comply with zoning ordinances.

While specific details can change, here are common considerations for ADUs in Charleston County:

  • - Zoning Compliance: The property must be zoned for single-family residential use, and specific overlays or restrictions may apply to areas like Riverland Terrace.
  • - Size and Setbacks: There are typically limits on the size of the ADU and required setbacks from property lines, ensuring it doesn't encroach on neighbors.
  • - Owner Occupancy: Often, at least one of the dwelling units (either the primary or the ADU) must be occupied by the owner of the property.
  • - Parking Requirements: Adequate parking must be provided for both the primary dwelling and the ADU.
  • - Permitting Process: All ADU construction requires building permits from Charleston County. This involves submitting detailed plans for review and approval.
  • - Unit Separation: ADUs must be clearly separate from the main dwelling, with their own entrance, and meet all building codes for habitability.

Important Note: It is crucial to consult the most current Charleston County zoning ordinances and building codes before planning any ADU project. Amber Dollarhite can connect you with local architects and builders experienced in navigating these regulations.
