It's not the actual weight, but the weight rating of the trailer which determines if brakes are required on the trailer, and they vary from state to state. In most states, trailer brakes are required on any trailer with a GVWR of 3,000 lbs. or more. In some states, the requirements may be as low as 1,000 lbs.

Start by dropping your trailer. You will notice there are wheels on only one end. A trailer like that is a "semitrailer." A "full trailer" has wheels at both ends. The official name is a "tractor-semitrailer," shortened to "semi."

Also called semi, is a detachable trailer for hauling freight, with wheels at the rear end, the forward end being supported by the rear of a truck tractor when attached.
It's short for "semitrailer". The entire rig is properly called a tractor-semitrailer. It's a semitrailer because it's only part of a trailer; it only has the back set of wheels (the front wheels under the cargo area are attached to the tractor, the part with the engine and the driver's cab).
There is no minimum weight.

Semi-trailers come in different sizes and not all are made with the same materials and components or extra features. A 53-foot empty semi-trailer can weigh anywhere from 10,000 to 25,000 pounds.
Lights are always required to be installed on a boat trailer. This is so no one runs into the back of the trailer, especially at night.
