Tiny House-What Is Zoning
First off, zoning is separate from building codes. Cities, townships, and counties can all have different zoning regulations. (They can have different building codes also, but that’s a different subject and they don’t vary as widely.).
Building codes specify the minimum standards for the construction of any house, or how a house should be built. Zoning is different. Zoning covers where your tiny house can be occupied. And there are a wealth of reasons including health, safety, and financial as to why zoning controls where you can locate your tiny house.
Zoning can require minimums for emergency vehicle access (safety); sewer or septic connections, rainwater runoff control, municipal water or well water hookups (health); minimums for lot size, square footage of houses, and restrictions on how many residences can occupy a lot or given area (financial, as these largely “protect” property values). I’m not giving a comprehensive list, these are just examples of the types of regulations included in zoning.
Again, building codes cover how a house is built. Zoning covers where and how many houses can be placed on a property, and how services and utilities must be accessed.
