Final answer:
In 2014, the Virginia General Assembly changed the trigger number to more than 4 rental units, meaning landlords with more than 4 units are subject to the Virginia Residential Landlord Tenant Act.
Step-by-step explanation:
The student's question pertains to a change made by the 2014 Virginia General Assembly regarding the Virginia Residential Landlord Tenant Act (VRLTA). The trigger number indicates how many rental units a landlord must have before the VRLTA applies to them. Prior to the change, the VRLTA applied only to landlords who owned more than 10 rental dwellings or more than 4 single-family residences. In 2014, the Virginia General Assembly amended this provision, changing the trigger number so that landlords owning more than 4 rental units are subject to the VRLTA. This means that more landlords are now required to adhere to the regulations set forth in the Act, which provides a set of detailed regulations that stipulate the obligations and rights of landlords and tenants in Virginia.
