ADUs on the Rise: How Backyard Units Can Boost Your Financial Outlook

August 28, 2023

What does ADU mean in housing? An Accessory Dwelling Unit in housing refers to a secondary- self-contained unit located on the same property as a primary single-family home. ADUs are also popular with different names, such as in-law apartments and backyard cottages. They are self-contained living spaces with a kitchen, bedroom, and sleeping areas for independent living. Although ADU’s become increasingly popular, homeowners are recognizing their potential to increase their financial prospects. These backyard units, standalone cottages, or basement apartments offer the dual benefit of extra living space and potential rental income. ADUs allow homeowners to expand their income by renting their units to tenants and tourists. By availing of these ADU, homeowners improve their financial outlook through rental income, property value, and active participation in housing solutions.

The Financial Benefits of Building a Backyard Unit

Building a backyard unit offers a significant financial benefit. It can generate additional income by renting a backyard unit. Supplementing the homeowner's cash flow and covering loan costs. Additionally, extra living space often increases property value, leading to higher pay and tax incentives like deductions for depreciation and expenses. Some of the other financial benefits of building a backyard may include:

Home Value Appreciation

The addition of a backyard unit can highly contribute to home value appreciation. This little space generates rental income and enhances the overall property value. The increased square footage and functional living area can attract a broader range of potential buyers or renters, leading to a higher demand for the property. Backyard units often cater to the growing trend of multigenerational living, providing extra living space for family members or even serving as a home office. This adaptability can make the property attractive to a broader audience and increase its market value. Moreover, as the housing market values unique features and functional spaces, a well-designed backyard unit can set a property apart from others in the area, potentially commanding the best price.

 Short and Long-Term Financial Gain

ADU,s have gained popularity as a way to increase housing options and serve as a source of income for homeowners and real estate agents. Here is how they contribute to short-term and long-term financial gains:


Tourist Accommodation:

Depending on your location, you can list the ADU on platforms for short-term vacation rentals. This can lead to higher rental rates during peak tourism seasons.


Cost sharing:

If you are building ADU for extended family members, it can help share the cost and offers privacy too.


Equity Growth: 

As you pay down the mortgage on your property, your equity increases. The income generated from the ADU can help accelerate mortgage payments, further growing your equity.

 

Flexible Use: 

If your needs change, you can repurpose the ADU. For instance, if you no longer want to rent it out, you could use it for personal purposes like a home office, guest suite, or space for ageing family members.

Standard rules to follow when valuing an ADU

Having an Accessory Dwelling Unit (ADU) involves assessing several factors to arrive at an accurate estimate. Here are some basic rules to follow when valuing an ADU:

  • Consider your area's real estate market conditions, and identify supply and demand factors. Interest rates and local economic trends. These can highly influence the value of an ADU.
  • If you are still determining about valuing the ADU on your own, consider hiring a professional appraiser with experience in valuing ADUs. An appraiser can provide an attractive assessment of the ADU's value.
  • ADU size, layout, and number of bedrooms/bathrooms play a significant role in determining value. Larger, well-designed units with adequate amenities tend to have higher values.
  • Assess the functionality of ADU. Is it well-designed for comfortable living? Does it have its entrance, utilities, and parking? A functional and well-designed ADU is more valuable.
