Any discussion of trailer parks should start with the fact that most forms of low-income housing have been criminalized in nearly every major US city. Beginning in the 1920s, urban policymakers and planners started banning what they deemed as low-quality housing, including boarding houses, residential hotels, and low-quality apartments.

Trailer parks are not only cheap due to manufacturing; they’re also cheap thanks to their surprising exemption from most conventional land-use controls. Most cities zone very little space for trailer parks—presumably a reflection of the general bias against low-income housing. But where they exist, they are often subject to uniquely liberal land-use regulation, with minimal setbacks, fewer parking requirements, and tiny minimum lot sizes.

By combining these liberal land-use regulations with narrow streets shared by all users, we ironically find in many trailer parks a kind of traditional urban design more common in European and Japanese cities.
