It has 2 dwellings on property.

For non-primary residences, they have to follow all of the following rules to receive a permit: - the property must be a minimum of one (1) acre in size (designed as a precaution to disturbances)- The building standards of the underlying zone district must be met - Adequate parking is provided - Defensible Space requirements are met - Valid water and sanitation must be demonstrated - No more than five (5) bedrooms are in the dwelling As time goes on, they continue to become more strict on the rules listed above here, and are actively regulating it.

It's technically not an ADU if it's the only property on land as it's an accessory dwelling unit to a main unit.

@Anthony Britto Additional Dwelling Units are now by right in RI.

But realized they were a lot more hoops to jump through with the city to make it a separate dwelling unit so we have opted to make it an extension of the home.

The section continues, “… Bed and Breakfast establishments, boarding homes, dormitories or multiple units, or any other similar lodging arrangements are specifically prohibited.”Section 3 – Commercial Use – states, “…no part of a Lot or Dwelling shall be used or caused to be used or allowed or authorized in any way, directly or indirectly, for any business, commercial, manufacturing, mercantile, storing, vending, or other such nonresidential purposes…”.

However, the City of Columbia only allows a max of 3 unrelated persons per dwelling unit.

By placing more emphasis on the condition of residents’ dwellings, the new inspection model aligns more closely with stakeholder expectations regarding housing quality.

It has 2 separate dwellings.

Another example is converting the garage into an Accessory Dwelling Unit.
