Have you ever rented the unit in someone’s basement? Maybe your spouse’s mother moved into your “Mother-In-Law Unit” above your garage? Or have you ever traveled and stayed in a pool house for your stay? Commonly referred to as “Mother-In-Law” units, homeowners use these as a way to fill the space in their home and gain residual income, either from vacationers or long-term tenants.
The official terms for these units are Additional Dwelling Units (ADU) or Detached Additional Dwelling Units (DADU’s), and are defined as extra spaces in homes and on properties where someone can live completely independent of the main house.
These units can be almost anywhere on the property, but they are usually located in the basement, in the backyard, or above the garage. They have their own bathroom and kitchen facilities, and sometimes they share laundry with the main house.
Thinking of adding a unit to your home? Here are some benefits and risks, as well as important aspects to consider before you build:
Homeowners can maximize their investment by renting out the extra space to long-term tenants for short-term vacationers. These tenants can help pay off debt or create an extra stream of income to pay for other needs or wants.
Depending on several factors, including the size of the unit, the market in the area, and other factors, each homeowner should decide which option they are more comfortable with. These decisions should be made before they list the unit for rent to best market to the right audience.
An obvious risk is that when you open your space to a stranger, there’s a possibility that things might end poorly. Either the tenants could turn out to be untrustworthy, or unreliable, leading to a financial burden.
To minimize the risks, it’s a good idea to use an application process to check backgrounds and employment history as a tool to get to know the potential tenant. Make sure to adhere to the National Fair Housing Laws and your local regulations.
Things to Consider:
- What are the shared spaces?
- Would you be comfortable sharing those spaces, and potentially appliances, with a new person each weekend, or would you rather get to know the long-term tenant who would use those on a consistent basis?
- Rooms like the kitchen can be great for those who want to get more interaction from their vacation renters. However, sharing one bathroom between the homeowners and the visitors can be uncomfortable and risky.
- Would you be okay with a long-term renter using your laundry facilities? What kind of access would they need to the house in order to use those machines?
- What is the size of the ADU/DADU?
- Is it truly a space where someone could live, or would it be too tight to fit all the necessary appliances?
- Does the unit adhere to your local housing codes as a livable space?
- How close are the units and what noise level are you comfortable with?
- As a long-term landlord, tenants have the right to quiet enjoyment without the landlord barging into their space or controlling their activities. If the unit is in the basement and the tenant has friends or family over, that noise could permeate into your unit in the late hours of the night. A way to prevent this is to be sure to layout quiet hours and expectations before they sign the lease or make an agreement so that you and the tenant are on the same page.
- The same goes for the rules in the vacation rental listing. Managing expectations is the first way to create a relationship with the tenants, even those there for the weekend.
- What improvements are required to make the unit livable?
- Do you need to add a kitchen or a bathroom? What are the costs associated with those improvements and would the market-rate rental prices make up for those improvements? You might not get your money back within the year, but if you’re dedicated to making the space worth it to rent it out over the next few years, these improvements, and financial obligations are necessary.
- If these initial investments aren’t viable for your situation, it might be a good idea to look at other options to earn rent from your home, including adding roommates with whom you’re willing to share all the common spaces.
Whatever you decide, it’s important to be familiar with the rental market and regulations in both your local region and your neighborhood.
