In North Texas, all of these homes are usually single family detached homes that do not share a wall. Oftentimes, the homeowners associations take care of the yards, and where that is not the case, there is just less yard to be concerned with.

Why Consider PATIO, GARDEN and ZERO LOT LINE Homes? Are you ready to downsize or do you desire a lower maintenance lifestyle? Then a patio home, garden home, or zero lot line home community may be a great choice for you! Those terms are often used interchangeably, but I always think of a patio home or garden home as a single family home on a lower maintenance lot. Zero lot line homes share those characteristics, and are actually built on the property line on one side.
