Substandard Units
Substandard units are those that either lack plumbing or are
overcrowded. They are an important indicator of housing
condition, especially when concentrated at the community
or municipal level where they can potentially weaken a
neighborhood.
There are relatively few substandard units countywide,
approximately 1.2% of the total occupied units in 2010.
This was a decrease from 2000 when 1.8% of homes were
substandard. The reduction comes from a drop in
overcrowded units, which also dropped at national and
statewide levels.
Bathrooms
A home with only one bathroom can be significantly less
marketable than those with two or more. Even those who
prefer smaller homes usually want more bathrooms.
Between 2000 and 2012, the average number of
bathrooms in new single-family homes increased from 2.8
to 2.9, and from 2.4 to 2.6 in single-family attached
homes. Neighborhoods with a higher percentage of homes
with less than two bathrooms may be less marketable than
other areas.

Home and Lot Size
It is a general trend in the United States that single-family detached homes have gotten larger over the
last century. This is especially true for suburban counties, such as Montgomery County, where the
median detached home size has increased by fifty percent since the 1960s. Interestingly, lot sizes have
actually been shrinking over the last couple of decades while home sizes continue to grow larger.
Homebuyers still seek more living area for their dollar, but they are willing to do so on a smaller area of
land. It also helps that some newer developments are designed more efficiently and provide common
open space, paths, and other amenities as a substitute for bigger private yards around each home.
