Accessory Dwelling Units Montgomery County, MD: A Smart Investment

Looking to invest in a smart, cost-effective way to expand your living space, add room for a family member and boost your property value? Consider building an Accessory Dwelling Unit (ADU) on your Montgomery County, MD property. In this blog post, we’ll break down everything you need to know about ADUs in Montgomery County and how they can benefit you and your family and the community.

What are Accessory Dwelling Units?

Accessory Dwelling Units, or ADUs, are self-contained living spaces that are commonly built in the backyard of a primary single family property. They can serve as guest houses, in-law suites or rental apartments for additional income. In Montgomery County, MD, ADUs have become popular due to their potential to increase the value of a property and provide extra space without having to complete an addition. In 2020, the county amended its zoning laws to allow for easier permitting and construction of these units within certain areas.


An Accessory Dwelling Unit, commonly known as an ADU, is a complete and independent living area added to a single family property. In Montgomery County, MD, the legal definition of an ADU is an apartment-like structure that can be attached or detached from the primary residence. The architecture and area of ADUs must comply with local zoning codes and building regulations. Amendments are underway in Montgomery County to increase the number of properties that can legally have ADUs as they provide homeowners with additional income streams while addressing affordable housing needs in low-density residential areas.


Adding an ADU to your Montgomery County, MD property can provide numerous benefits. Firstly, it offers additional income potential for homeowners who choose to rent out the space. Secondly, it increases property value and opens up rental opportunities in a highly competitive area. Finally, ADUs offer flexible living arrangements for family members (i.e. aging parents) – complete with their own private entrance and living area.

By amending the architecture of your property with an apartment-like addition like an ADU in Montgomery County, MD you have a whole new area of possibilities that can cater to various needs. This investment is beneficial for homeowners aged 30-65 looking to expand their living spaces without having to move or compromise on privacy and comfort.

Types of ADUs

Attached and detached ADUs are the two most common types of Accessory Dwelling Units. Attached units include basement apartments or garage conversions, which connect to the main house and often share utilities. Detached structures such as small cottages or backyard studios provide additional living space while maintaining privacy from the primary home.

When considering adding an ADU to your property, it is important to understand the different types available to determine which best suits your needs. Some factors that may influence your decision include area size, existing architecture, and budget constraints. To help you make a complete assessment of what will work for you, here are some key points to consider:

  • Attached units like basement apartments or garage conversions can be more cost-effective because they utilize existing space.
  • Detached structures such as small cottages offer more flexibility in terms of design options and can potentially increase property value.
  • Be sure to check local zoning laws before making any amendments or additions to ensure compliance with regulations regarding minimum lot size requirements and other restrictions.

In summary, when looking at accessory dwelling units Montgomery County MD homeowners should know there are various types available for consideration based on their unique needs. Whether attached or detached, each type offers specific benefits that should be weighed carefully against personal preferences and financial considerations.

Why Invest in an ADU in Montgomery County?

Adding an ADU to your property in Montgomery County, MD can be a smart investment for several reasons. Firstly, it has the potential to significantly increase your property value. Secondly, you can generate rental income by leasing out the unit. With the growing demand for affordable housing options in Montgomery County, this is an opportunity that cannot be missed.

Increasing Property Value

Adding an accessory dwelling unit (ADU) to your property can increase its value by adding square footage and providing additional living space. This not only makes your property more attractive to potential buyers, but also gives you a unique selling point when it’s time to sell. With the growing demand for flexible living options, having an ADU on your property can be a smart investment that pays dividends in both rental income and resale value.

Rental Income Potential

Renting out the ADU can provide a steady stream of passive income. By having an additional dwelling on your property, you can potentially double your rental income without purchasing another property. You could even consider using this money to pay off your mortgage faster or reinvest it into other properties.

You can set rental rates that allow you to recoup your investment quickly. Renters are often willing to pay higher rents for access to amenities like private entrances and kitchens which ADUs offer. By doing some research on similar rentals in the area, you can ensure that you’re charging a competitive rate while still making a profit from your investment in the long run.

Meeting Growing Demand

As the demand for affordable housing options in desirable areas like Montgomery County continues to rise, accessory dwelling units are becoming an increasingly popular solution. Downsizing baby boomers and younger generations seeking urban lifestyles with nearby amenities or detached living spaces are also contributing to this growing demand. Investing in an ADU not only provides a valuable source of rental income but is also a smart move in meeting the needs of today’s changing housing market.
