This is an interesting article about how differences in zoning and building laws bring about differences in a community. One community has mixed use within a single block and much lower costs to own a home, while another has homes without business nearby and higher home costs.
A typical house lot in a newer neighborhood of Matamoros has only around 1200 square feet, while in Brownsville, new subdivisions have lots around 5400 square feet. Interestingly, the lot size trends appear to be diverging: Matamoros’ new lots are smaller than those in older parts of the city even as car ownership has soared, while Brownsville’s are much larger. Older areas of both cities, dating back to the late 1800s or early 1900s, both tend to have house lots of around 3,000 square feet, although in different configurations (Matamoros, for instance, never used rear alleys).
New homes in Matamoros are often a tiny, in some cases little more than 500 square feet, but appear to be mere placeholders for expansion. Usually set back about 15-20 feet from the lot line, these homes are swiftly expanded forward into the setback and up a story or two using simple construction techniques, with the result that after no more than a decade or so, the street’s appearance is completely transformed, and no longer appears mass-produced. (Single-use zoning seems to be unknown or unenforced, as numerous small commercial establishments can be seen cropping up, mid block, along these streets.)
