Building an accessory dwelling unit (ADU) in your backyard is a popular trend in America. There are multiple television shows about tiny house ADUs and renovation programs about adding living units to an existing property. In addition to expanding your living space, an ADU house is a great solution for multigenerational families, growing teens, people who work from home, and homeowners who need a little extra income.

What is an ADU in Real Estate?

An ADU home is a fully self-contained living unit on the same lot as a primary home. An ADU, in real estate terms, has its own kitchen, bathroom, and entrance. These living units are designed to house tenants or family members independently from the main house. They can be detached structures in the backyard, converted spaces like garages, or additions attached to the main house.

Benefits of Backyard ADUs

Financial Benefits of ADUs

There are numerous financial benefits to having an ADU on your property, including:

  • Rental income potential: An ADU can bring in $1000 per month or more, depending on size and location. Although there’s an initial cash outlay for building an accessory dwelling, many ADUs pay for themselves within 5-10 years through rental income.
  • Qualification for a higher mortgage: If you’re applying to buy a home for sale with an ADU, you could get a bigger loan based on the income potential.
  • Property value increase: An ADU can increase your property value by 20-30%. When you sell your home, you can attract buyers specifically looking for a house with an ADU for sale.
  • Tax benefits: Depending on how you use the ADU, you could be able to deduct depreciation on your taxes. You may also be able to deduct business expenses such as maintenance and upgrades. Be advised that an ADU can increase your property taxes; it’s worth investigating the impact on your taxes before you buy ADU house plans.

Lifestyle and Family Benefits of ADUs

For homeowners, there are numerous advantages to having a backyard ADU. They can serve as:

  • Housing for aging parents: You can stay close to elderly relatives while allowing them to maintain the privacy and independence they’ve always enjoyed.
  • Independent space for grown children: Adult children are living at home longer while they save up for a down payment on their own house. An ADU lets them have their own lives while keeping their costs down.
  • Accommodations for caregivers: If you need caregiving or childcare on-site, an ADU can give them their own living space on your property.
  • A guest house for visiting family and friends.
  • Temporary housing during main house renovations.
  • A workout or meditation space.

Community and Social Benefits:

ADU real estate can help address local housing shortages and provide affordable rental options in cities where people struggle to make rent. You can also use your ADU to support temporary and seasonal workers, students, or anyone else who needs low-cost housing.

Types of ADU House Plans

ADU house plans cover a wide range of building types. When planning your ADU addition, choose a design that will suit your purpose and fit your lot size and budget.

Detached Backyard ADUs

These units offer the most privacy and flexibility. Since they’re completely separate from the main house, they’re ideal for renting out to tenants or providing a fully independent living space to older relatives or adult children. These units can be designed to match your home’s architecture. For smaller lots, a tiny house ADU can be perfect.

Garage Conversion ADUs

Garage conversions are a cost-effective way to create additional living space without adding on. With the right design, you can still maintain some parking space or storage within your current garage space.

Attached and Above-Garage ADUs

These units can be less expensive than detached ADUs since they share walls or floors with the existing home. You can include these types of ADUs in larger home renovations, which will save money over a dedicated building project.

Planning Your ADU Project

Once you’ve decided on the type of ADU home you want to build, it’s time for the next steps in the project! a

Zoning and Permit Regulations

Local zoning regulations can limit the size of the unit, dictate where it can be placed on your lot, and even determine who can live in it, so check the zoning restrictions for your area before you start. You’ll also need to check the setback rules for your lot, which limit how close your ADU can be to property lines. Other factors, such as parking space requirements, can also impact your plans.

Design Considerations

A well-designed ADU shouldn’t clash with your existing home but still needs to meet the needs of whoever will be using the space. Consider the architectural style for the ADU and its distance from the main house, as well as where entrances and windows will be placed and what level of soundproofing you want. If you’re building for aging family members, make sure you incorporate accessibility features like step-free entries, wider doorways, and accessible washrooms.

Budgeting and Financing

ADUs can be a smart investment but set out a budget in advance and stick to it. Construction costs typically range from $100,000 to $300,000 or more, depending on the size, layout, and features you choose. Financing options such as construction loans, home equity loans, or cash-out refinancing can help with up-front costs; investigate your options before breaking ground to make sure you’ll be able to get the funds you need.

The benefits of building an ADU in your backyard extend far beyond adding square footage. From generating rental income to providing flexible family housing solutions and supporting working from home, ADUs offer a unique opportunity to increase your property’s value for the long term. With proper planning and execution, an ADU can provide years of benefits for your family and secure your financial future.
