Zoning regulations can vary widely from city to city and even from one neighborhood to another within the same city. It is important to check with your local government to find out about specific zoning regulations and requirements for tiny homes in your area, which can include information about minimum square footage requirements, setbacks, and other rules.
In general, tiny homes on wheels aren't considered a type of residential dwelling, and as such, aren't subject to the same zoning regulations as other types of homes. Some municipalities may have specific regulations for tiny homes listed as RVs, while others may not have any regulations in place yet.
In Dallas, Texas you can check with the city's building and zoning department to find out what the regulations are in your area and what type of zoning will allow a tiny home to be placed on a piece of property. You should also check to see if there are any building codes or permits that are required for tiny homes or adding Accessory Dwelling Units (ADUs). Additionally, you should check with any home owner association (HOA) in case there any specific restriction or regulations they might have in place.
It is highly recommended to consult with a local real estate agent and attorney to understand the local laws and regulations while looking for land to purchase for a THOW. They will be able to provide you with the most up-to-date information and guide you through the process of finding a suitable property to place your tiny home on wheels.
