When it comes to housing options, detached zero lot line homes have been gaining popularity in recent years. These unique single family properties offer a blend of urban living and suburban comfort, but like any housing choice, they come with their own unique set of advantages and limitations.

We became aware of detached zero lot line homes while recently touring several new housing communities in Southern California. Unbeknownst to us at the time, one of the single family home communities consists of properties that, in essence, share property lines. What caught our attention were patio areas that “touched” the exterior walls of a neighboring home. After inquiring, we learned that these new homes were classified as zero lot line properties, which are also referred to as “detached condos”.

Anyone searching for affordable housing options, or planning to downsize, or under the assumption that they can only afford a townhome or condominium will want to learn more about detached zero lot line homes.

In this article, we’ll delve into the pros and cons of detached zero lot line homes, exploring why they are becoming an attractive option for many homebuyers and what to know upfront if you are considering this type of home and community.

What’s a Detached Zero Lot Line Home?

Detached zero lot line homes, often referred to as detached condos, patio homes or garden homes, are a type of housing where the structure is built very close to or directly on the property line, maximizing the use of available space. These homes typically have little to no yard on one or more sides, but often compensate with private courtyards, rooftop gardens, or shared green spaces.

A detached zero lot line home will typically have one exterior wall that serves as the “dividing property fence” with a neighbor. In other words, one neighbor’s side area will run exactly to the surface of an adjacent neighbor’s side exterior wall.

It is also not uncommon for a detached zero lot line home to have one wall without windows to enhance the privacy of the adjacent neighbor. Signs of a poorly designed detached zero lot line homes, on the other hand, are two nearby walls that have windows that partially facing each other.

Though townhomes, row houses and duplexes are also all classified as zero lot line homes, for the scope of this article, we are focusing on “detached zero lot line homes”, due to their rising popularity.

Given the legal complexities of “sharing property lines”, these communities are often managed by Homeowners Associations (HOAs) in similar fashion as condominium communities. There will likely be some kind of “shared common maintenance agreement” in place that defines shared responsibilities and policies for maintaining exterior elements between neighbors and an HOA.


The Appeal of Detached Zero Lot Line Homes


Urban Convenience with Suburban Comfort

Detached zero lot line homes typically strive to blend convenient city living with suburban comfort. Residents can enjoy the convenience of urban amenities (e.g. nearby shopping; public transportation; business centers; etc.) while having a more private and cozier space.

Buyers of detached zero lot line properties may also be attracted by one or more of the following tradeoffs:

  1. Freeing up time by living in a more convenient location that costs more
  2. Living in a larger home in exchange for smaller, less private outdoor areas
  3. Downsizing from a larger property for an easier-to-maintain smaller property with convenient amenities


Low Maintenance

With limited outdoor space, these homes require less yard maintenance, making them ideal for busy professionals or those seeking a hassle-free living arrangement, such as recent retirees.

The umbrella term of “detached condos” is also instructive for understanding the maintenance benefits of detached zero lot line homes, as monthly HOA/condo fees are used to cover the on-going maintenance of common grounds and amenities (e.g. club house; walkways; pool; landscaping; etc.).


Community Benefits

Many detached zero lot line developments include modern shared amenities and spaces, fostering a friendly sense of community and neighborly interaction.

The extra amenities can serve as a valuable complement for homes with smaller square footage or reduced outdoor spaces, such as club houses with exercise equipment, party rooms with kitchens, and outdoor barbecue areas.


Economical Use of Land

Zero lot line construction allows developers to maximize land use in densely populated areas, contributing to efficient urban development with the goal of providing more affordable housing options in convenient areas where people desire to live.

Advantages of Detached Zero Lot Line Homes



Detached zero lot line homes often come with a lower price tag compared to comparatively-sized single-family homes with similar amenities. Affordable pricing is likely the most important benefit of purchasing a detached zero lot line property.

Affordability is primarily a result of sacrificing lot size and privacy in return for more interior square footage than could be afforded on a “standard” sized lot (a lot with a front, back and two side yards).

New zero lot line communities are especially striving to provide a stronger value proposition to prospective homebuyers by providing in-demand home features, community amenities, as well as passing along cost-savings by incorporating “more homes per acre” within a given development area.


Reduced Yard Maintenance

The lack of a traditional yard reduces the time and effort required for landscaping and maintenance, appealing to individuals with busy lifestyles or those who prefer minimal outdoor upkeep.


Increased Privacy

Though, in general, detached zero lot line homes offer less privacy than homes on standard lots, they certainly offer more privacy than other zero lot line property types, such as condominiums and townhomes.

While detached zero lot line homes are close to neighbors, they often include private outdoor spaces like patios or courtyards, providing a sense of seclusion for enhanced outdoor enjoyment.

New detached zero lot line development communities are making concerted efforts to increase privacy (both visual and auditory) with well-designed outdoor patio spaces, superior indoor sound insulation, and strategically placed windows.


Urban Proximity

Zero lot line homes are typically situated in urban or suburban areas with easy access to shopping, entertainment, and employment opportunities.

Homebuyers looking to reduce their commute times or purchase in historically high-priced urban areas should keep an eye on new home developments, as many are implementing detached zero lot line designs.

Community Atmosphere

Shared green spaces and common areas encourage a sense of community, fostering relationships among neighbors and creating a supportive living environment.

The right suite of community amenities for a given homebuyer can also represent additional cost-savings and, perhaps more importantly, time-savings.


Limitations of Detached Zero Lot Line Homes


Limited Outdoor Space

The main drawback of detached zero lot line homes is the lack of a traditional yard, which can be a downside for those who enjoy gardening, outdoor activities, or simply having more outdoor room.

This particular limitation, however, may actually be an attractive feature for some homebuyers, such as retirees downsizing to a home that is easier to maintain or families that require more indoor living space.

Noise and Privacy Concerns

Due to the close proximity to other neighbors and to the street, residents of detached zero lot line homes might experience more noise and reduced privacy than those living in homes on standard single family lots. This limitation could be a concern for individuals seeking tranquility and a certain minimal level of privacy.

Though checking for adequate sound insulation is more challenging than checking for visual privacy, well-designed, contemporary detached zero lot line developments have been striving to meet these key needs of residents.

Reduced Resale Value

The resale value of detached zero lot line homes, like all residential property types, will be influenced by a number of factors such as location, nearby amenities, recent comparable sales, and the overall real estate market. Any of these variables can lead to variability and uncertainty in investment returns.

Given that detached zero lot line homes are on smaller lots than comparably sized homes on standard lots, zero lot line homes should not, in theory, appreciate in value as fast. However, when compared to other types of zero lot line properites (e.g. condos, townhomes and duplexes), detached zero lot line homes should consistently appreciate faster due to having more square footage, outdoor areas and better privacy features overall.

A key variable that will impact resale value is the governing Homeowners Association (HOA) and associated fees and rules. A well-run HOA for a highly efficient and well-maintained community is critical to maintain a competitive resale value. Conversely, for example, a comparable single family community with standard lots could be at a disadvantage against a detached zero lot line community, if the standard lot community has an HOA with a poor reputation or a record of escalating fees and exhorbitant maintenance charges.


Limited Expansion Opportunities

Detached zero lot line homes often have limited potential for expansion, making it challenging to accommodate changing family n meeds or lifestyle shifts. However, similar expansion limitations will likely be encountered in other types of zero lot line properties and communities, as well.

One highly effective method of getting more usage out of existing square footage is to apply transformable design to key interior spaces for increased functionality.


Homeowners Association (HOA) Rules

Many zero lot line communities have HOAs that impose rules and restrictions, which might not align with everyone’s preferences or lifestyle choices.

In addition, it is imperative to research the transparency of the HOA to assess how efficiently it is managed, as well as the corresponding community (e.g. historical fees; overall condition of shared infrastructure; recurring maintenance fees; etc.).


Property Line Issues

Pertaining to key HOA rules, prospective homebuyers of a zero lot line home will need to understand upfront how property lines are managed, including: what is allowed; what is not allowed; what is the responsibility of the HOA; what is the responsibility of the homeowner; and how property line disputes are handled.

In particular, be sure to not take on any unnecessary liability, such as doing any maintenance work that is the responsibility of the HOA (e.g. painting an exterior wall that is deemed “common property”).

Also be sure to research your state’s “zero lot line” laws and homeowner rights. For example, Florida law grants homeowners of zero lot line properties access to four feet of a neighbor’s property in order to maintain a corresponding area of property.
