With increasing urbanization and a growing need for more affordable housing, many people are turning to attached accessory dwelling units (ADUs) as a viable solution. Attached ADUs are becoming more popular as they offer an efficient way to add additional living space to single-family homes. But what exactly are attached ADUs, and what should you know before building or renting one? In this article, we'll explore the different types of attached accessory dwelling units, their advantages and disadvantages, and what you should consider before investing in one.

Accessory dwelling units (ADUs)

are an increasingly popular way to add living space to a single-family home. An attached ADU is one that is physically connected to the existing home, typically located above a garage or below an existing home.

In this article, we will explore the different types of attached ADUs and discuss their benefits and drawbacks. The first type of attached ADU is an apartment-style unit. These units typically have their own kitchen, bathroom, and living space. They are usually connected to the main house by a staircase or elevator, making them ideal for families with elderly parents or young adult children who want their own space but still want to be close to the family. The second type of attached ADU is a studio-style unit. These units are typically smaller than apartment-style units and may only have a kitchenette and bathroom.

They are great for short-term visitors or as an income-generating rental unit. The third type of attached ADU is a hybrid unit. This type of unit combines the features of both apartment-style and studio-style units, making it a great option for those who want the convenience of both but don’t have the space for two separate units. No matter which type of attached ADU you choose, there are several benefits to consider. First, they can provide additional living space without taking up too much land or having to build a separate structure. Second, they can be used as a rental property and generate additional income.

Lastly, they can be used as a place for family members or visitors to stay while they are in town. However, there are also some drawbacks to consider when building an attached ADU. First, they can be more expensive than other types of dwellings due to the need for additional plumbing and electrical work. Additionally, if not done properly, the addition of an attached ADU can alter the existing structure’s aesthetics and value. Lastly, depending on local regulations, there may be restrictions on how big an attached ADU can be and how many people can occupy it at one time.

Types of Attached ADUs

There are three main types of attached accessory dwelling units (ADUs): apartment-style, studio-style, and hybrid units.

Each type has different benefits and drawbacks that should be considered when deciding which is best for your home.

Apartment-Style Unit

An apartment-style unit is typically located above a garage or an addition to the existing home. It typically includes a full kitchen and bathroom, as well as a living area, bedroom, and closet. The benefits of this type of attached ADU include additional living space, increased privacy, and potential rental income. The drawbacks of this type of unit include the cost of construction and the potential impact on property taxes.

Studio-Style Unit

A studio-style unit is usually located below an existing home or in an addition to the existing home.

This type of unit typically contains a kitchenette and bathroom, as well as a living space and bedroom area. The benefits of this type of attached ADU include having a relatively low cost of construction and the potential for rental income. The drawbacks include limited privacy and potential noise issues.

Hybrid Unit

A hybrid unit combines elements from both the apartment-style and studio-style units. It typically includes a full kitchen and bathroom, as well as a living space and bedroom area.

The benefits of this type of attached ADU include increased living space, increased privacy, and potential rental income. The drawbacks include the cost of construction, potential noise issues, and potential impact on property taxes.

Building an Attached ADU

Building an attached ADU can be a complex process that involves navigating regulations, permits, and construction considerations. It’s important to start by doing research on applicable regulations and laws, including zoning laws and building codes. Depending on the jurisdiction, a permit may be required before any construction begins.

It’s also important to consider the costs associated with building an attached ADU, which may include a variety of items such as labor, materials, and permits. In some areas, it may be necessary to hire a professional contractor for the project. It’s important to research potential contractors and make sure they are properly licensed and insured. Additionally, it’s essential to consider the size and layout of the attached ADU and any potential impact on the existing structure or landscaping.

Finally, it’s important to consider energy efficiency when building an attached ADU. Depending on local laws and regulations, it may be necessary to install energy-efficient features such as insulation, windows, and doors that meet certain standards. Additionally, it’s important to consider the use of sustainable materials such as recycled materials and low-VOC finishes. Attached accessory dwelling units can be a great way to add extra living space to a single-family home without having to build an entirely new structure.

However, there are a few factors to consider before making the decision, such as cost, regulations, and construction considerations. Doing thorough research beforehand is key to making the best decision for your situation.
