FAQ
What is an ADU?
An ADU (accessory dwelling unit) is a secondary dwelling located on the same property as a single-family home. They can be connected (like converting a basement or garage) or separated (like a backyard cottage). ADUs are designed as permanent homes with standard utilities, a proper foundation, and compliance with local building codes.
What is a tiny house?
Tiny houses, on the other hand, are usually independent, very compact dwellings. Tiny homes, often less than 400 square feet, embrace minimalist living and efficient use of space. Some are built on fixed foundations, while others are built on wheels, especially if mobility is a priority.
ADU vs Tiny Home: Key Differences
size and layout
Tiny homes focus on ultra-efficient layout features, such as lofted sleeping areas and versatile furniture. ADU designs are typically larger and often offer a full kitchen, living room, and bedroom space similar to traditional homes. This difference alone will determine your decision when comparing ADU and tiny home options.
Permanence and legal status
ADUs are treated as permanent housing and are subject to the same safety and construction requirements as the main house. This means ADUs can increase property value and often meet zoning rules more easily. Tiny houses vary depending on how they are classified. Some are considered RVs, which may limit where you can live long-term.
cost and value
Tiny homes typically cost about $30,000 to $70,000 to build or buy, making them attractive to those looking for affordability. ADUs require more investment because they are built to full residential standards. Although costs are higher for mid-sized new construction, ranging from $180,000 to $400,000, ADUs often provide greater long-term returns because they can increase property value and generate rental income.
fit your lifestyle
Tiny homes appeal to people looking for a simple and flexible lifestyle. Ideal for people who live a minimalist lifestyle or are planning to move in the future. ADUs are perfect if you’re looking for stability and everyday comfort. Popular as a multi-generational residence, guest accommodation, or rental opportunity.

How to decide between an ADU and a tiny house
Choosing between an ADU and a tiny home depends on your goals. If you’re looking for mobility, minimalism, and low costs, a tiny home may be the way to go. If you’re looking for more square footage, long-term value, and reliable regulatory compliance, an ADU is often the better choice. Think about your lifestyle, wealth, and long-term plans.
In the comparison between ADU and tiny house, there is no universal winner. Each offers meaningful benefits depending on how you plan to use your space. You can take the time to evaluate what’s most important to you and take the next step with confidence, whether it’s building something small or a complete ADU.
FAQ: ADUs and tiny homes
Are ADUs more expensive than tiny houses?
Yes, in most cases, ADUs are built to the same standards as traditional homes, which means they cost more. Tiny homes typically have lower initial costs, but they may not add long-term value like ADUs.
Can a tiny house be used as a full-time residence?
It depends on local laws. Some regions allow tiny homes as permanent residences, while others allow them only as temporary or recreational facilities. When deciding between an addo and a tiny house to live in full-time, be sure to check zoning and building regulations first.
Which one is more advantageous in terms of rental income?
ADUs are usually a stronger option for generating rental income because they fully meet housing standards and can be legally rented in many locations. Depending on the classification, tiny homes may have restrictions on long-term rentals.
Which type is easier to maintain?
Tiny homes are often easier to maintain due to their smaller size. ADUs require the same type of upkeep as tiny homes, but offer more comfort and flexibility in your daily life.
