Private residential properties smaller than 90sqm are subject to an occupancy cap of six unrelated persons per property. [See section on temporary relaxation for larger properties below]
Unrelated persons refer to anyone who is not part of the same family unit.
Domestic helpers are considered part of the same family unit.
The occupancy cap also applies to tenants who sublet the property. As the property owner, you must ensure that your tenants follow the rules.
