When exploring housing options, the question "what are small houses called" often arises for individuals seeking affordable, efficient, and sustainable living solutions. The terminology surrounding compact dwellings is diverse, ranging from formal classifications to colloquial nicknames, each reflecting a unique approach to minimalist living. Understanding these names is essential for anyone navigating the modern real estate market or designing a space that prioritizes functionality over square footage.
The Spectrum of Small Dwellings
The definition of a small house varies significantly based on regional standards and architectural style. What constitutes a small home in a dense urban center might be considered spacious in a rural context. Generally, these structures prioritize essential living functions, eliminating unnecessary space to create an affordable and energy-efficient environment. The specific name often indicates the design philosophy, construction method, or intended lifestyle associated with the unit.
Accessory Dwelling Units (ADUs)One of the most common official classifications for a small house is an Accessory Dwelling Unit (ADU). Also known as a granny flat, in-law suite, or backyard cottage, an ADU is a secondary housing unit located on the same lot as a primary residence. These structures are legally recognized in many municipalities as a way to increase housing density and provide rental income or independent living space for family members.
Tiny Houses on WheelsPerhaps the most iconic answer to "what are small houses called" is the Tiny House on Wheels (THOW). These structures are built on a trailer chassis, making them mobile and exempt from traditional foundation requirements. Often ranging from 100 to 400 square feet, they appeal to those who value freedom and mobility, allowing owners to relocate their living room with relative ease.
Cabin and Cottage Variants
Beyond technical definitions, many people refer to small houses as cabins or cottages, particularly when the design is inspired by rustic or mountainous architecture. A cabin typically evokes a sense of wilderness and uses natural materials like wood, while a cottage often suggests a charming, cozy retreat, sometimes associated with vacation properties or quaint suburban settings.

Micro-Units and Lofts
In urban environments, the answer to "what are small houses called" frequently manifests as micro-units. These are studio-style apartments found in dense city centers, designed to maximize every inch of vertical space. Lofts also fall into this category, utilizing high ceilings and open floor plans to create a sense of airiness despite a minimal footprint.
Specialized Designations
Specific architectural movements have coined terms for small houses that emphasize efficiency and design. For example, a "laneway house" is a small secondary home built in the back lane of a larger property, common in Canadian cities. Similarly, a "park model" refers to a small house built on a steel chassis, designed to meet the standards of the Recreational Vehicle Industry Association (RVIA) for campground use.
| Type Name | Typical Size (sq ft) | Key Feature |
|---|---|---|
| Tiny House on Wheels | 100-400 | |
| ADU/Granny Flat | 300-700 | |
| Micro-Unit | ||
| Cabin | 400-1000 |
Ultimately, the label assigned to these compact living spaces is less important than the lifestyle they enable. Whether you call them tiny houses, ADUs, or cabins, these small structures represent a significant shift toward intentional living, challenging the notion that more space is always better.
