The terms overlap and are often used interchangeably. The most useful distinction: a casita typically refers to a detached structure on the property with its own kitchen, bathroom, bedroom, and living area (matching the Nevada legal definition of an accessory dwelling unit under AB 396). An in-law suite usually refers to an attached or integrated space inside or connected to the primary residence, often with its own bathroom and sometimes its own kitchen. Both serve the same purpose of providing independent living quarters for a family member. Kingdom & Co. designs both configurations depending on the property, the use case, and the resident’s needs.
