When searching for a new home, understanding the differences between housing types is essential. Duplex vs. townhouse? These are some of the housing options available for your future home. Knowing what is a duplex and what is a townhouse can help you decide which option best suits your lifestyle and long-term goals.

What is a duplex?

A duplex is a residential building divided into two separate units, typically with separate entrances. Each unit may be side by side or stacked one on top of the other, sharing a common wall. Duplexes can be owner-occupied, rented out entirely, or have one unit rented while the owner lives in the other.

Pros and cons of buying a duplex

Pros:

  • Potential rental income: One of the key advantages of a duplex is the ability to rent out one unit while living in the other, helping offset mortgage costs.
  • More space: Duplexes often provide larger living areas compared to apartments. 
  • Lower cost compared to single-family homes: While offering more space than a condo, duplexes are usually more affordable than a standalone house.
  • Investment opportunity: If well-maintained, a duplex can appreciate in value and serve as a profitable real estate investment.

Cons:

  • Shared walls: Although not as communal as a townhouse, living in a duplex still means sharing a wall with neighbors, which might affect privacy.
  • Responsibility for maintenance: Whether renting out one unit or living in both, maintenance falls entirely on the property owner.
  • Limited appreciation compared to single-family homes: Duplexes may not appreciate as much as detached homes in certain markets.

What is a townhouse?

A townhouse is a multi-floor home that shares one or two walls with adjacent properties but has its own separate entrance. Unlike a duplex, a townhouse is typically part of a row of similar homes, forming a community with shared amenities.

Pros and cons of buying a townhouse

Pros:

  • More privacy than a condo: Unlike condos, townhouses offer separate entrances and fewer shared common areas.
  • Lower maintenance: Many townhouses are part of homeowners’ associations (HOAs), which cover exterior maintenance and landscaping.
  • Affordable alternative to single-family homes: Townhouses generally provide more space than a condo but cost less than a standalone house.
  • Community amenities: Some townhouses come with shared facilities like pools, gyms, and clubhouses.

Cons:

  • HOA fees: Townhouses often have monthly or yearly HOA fees, which add to overall costs.
  • Less flexibility: HOAs may have rules regarding renovations, exterior decorations, or even renting out the property.
  • Shared walls: While more private than a condo, a townhouse still involves shared walls with neighbors, which can impact noise levels.

Duplex vs. townhouse vs. condo: key differences

Understanding the difference between a duplex and a townhouse can help make an informed decision.

  • Duplex vs townhouse: Duplexes offer more independence since they have only one other unit attached, whereas townhouses are usually part of a larger row of homes. Townhouses often come with HOA fees and shared amenities, while duplex owners are responsible for their property entirely.
  • Condo vs townhouse vs duplex: Condos typically involve shared buildings with multiple units, whereas townhouses provide individual entrances and slightly more privacy. Duplexes, on the other hand, offer more independence with only one shared wall and sometimes rental opportunities.

Townhouse vs. duplex: which one is right for you?

Deciding between a townhouse or duplex depends on your financial goals, lifestyle preferences, and desired level of independence.

Choose a duplex if:

  • You want rental income potential to help pay the mortgage.
  • You prefer fewer neighbors and less reliance on an HOA.
  • You want more control over maintenance and modifications.

Choose a townhouse if:

  • You prefer lower maintenance, with exterior upkeep covered by an HOA.
  • You like the sense of community that comes with shared amenities.
  • You want a multi-floor layout that resembles a single-family home.

For buyers considering buying a second house, a duplex can be a strategic investment, while a townhouse offers an easier entry into property ownership. Additionally, when choosing between options, considering the best position for a house to face can help optimize natural light, ventilation, and energy efficiency, further enhancing the living experience.

Ultimately, both housing types offer distinct advantages, and the right choice depends on individual priorities, financial flexibility, and long-term plans.
