Difference between ADU and Tiny Home and Backyard Home and Guest Home

When it comes to finding the right housing solution for building an adu in Los Angeles, it can be hard to know where to start. With the emergence of new housing solutions such as Accessory Dwelling Units (ADUs), Tiny Homes and Backyard Homes, it can be daunting to decide which one best suits your needs. In this blog post, we’ll break down the key differences between ADUs, Tiny Homes and Backyard Homes, and discuss additional housing options like Guest Houses.

  1. Size and Cost of each type of home

ADUs from ADU Builders are typically larger than tiny homes and backyard homes, ranging from 100-800 square feet in size. They can cost anywhere from $40,000-$200,000 to build, depending on the size and materials used. Tiny homes, on the other hand, are typically smaller, ranging from 100-400 square feet. They usually cost between $20,000-$50,000 to build. Backyard homes are also usually smaller, ranging from 100-600 square feet, and they tend to cost between $30,000-$150,000. Finally, guest homes are usually the largest of the four types, ranging from 200-1000 square feet in size, and they usually cost between $50,000-$200,000.

  1. Zoning Requirements for each type of home

Zoning requirements can vary depending on the type of home you choose. An Accessory Dwelling Unit (ADU) is typically allowed in residential zoning districts, provided it meets certain requirements such as size, height, setback, and parking. Tiny homes, backyard homes, and guest homes may also be allowed in some zoning districts, but the rules can vary from city to city.

  1. Building Codes and Regulations

When it comes to building codes and regulations, ADU construction must adhere to local building codes, safety standards and zoning regulations. This includes plumbing and gas hookups, fire safety codes, and building codes and standards for structural soundness. Generally, the construction process for an ADU requires the same permitting process and inspections as building a new home. Tiny homes and backyard homes and guest homes, on the other hand, may not always comply with local building codes and regulations depending on the locality, and in some cases, may not require any permitting or inspections.

  1. Design Differences

The design differences between ADU, tiny home, backyard home, and guest home are quite vast. ADUs (Accessory Dwelling Units) are generally built to resemble a traditional single-family home and are located on the same property as a primary residence. Tiny homes are constructed to be much smaller and often are mobile, allowing them to be moved from one location to another. Backyard homes are similar to ADUs but are generally located on the same property as a primary residence, while guest homes are often separate from the primary residence and provide additional living space for visitors. Each of these types of dwellings have their own unique design considerations, from size and layout to materials and finishes.


The decision of which type of additional home to build depends on a variety of factors. ADUs, tiny homes, backyard homes, and guest houses all offer unique advantages and disadvantages that must be considered in order to make the best choice for your particular circumstances. Ultimately, what type of additional home you should build depends on your budget, the size of your property, and the end-use of the space. Careful consideration of all the factors will ensure you make the best decision for your needs.
