Which type of lot has a right-of-way on only one side?

The correct choice is the inside lot. An inside lot is characterized by having properties that are surrounded by other properties on all sides, except for one side which typically has the right-of-way or access. This means that it has a street or access road on just one side, which allows for entry and exit while being bordered by other buildings or lots on the remaining sides.

This definition differentiates inside lots from corner lots, which are located at the intersection of two streets and thus have two sides with right-of-way. Through lots, on the other hand, have access points on both the front and back sides, allowing passage through the property. Interior lots are another term often used interchangeably with inside lots but generally refer to the same concept. Overall, the key characteristic of an inside lot is that it features a right-of-way on only one side, making it distinct among the options provided.
