Where can I park a tiny house?

You want to secure the location before you order the house since most builders will not deliver to a unsecured location. THOWs generally cannot be parked in your driveway like a motor home. The property must be zoned for the size tiny house you have.
You can start by checking your State regulations here http://www.rvia.org/UniPop.cfm?v=2&OID=3531&CC=7616
Then call the County Zoning Agent for your target location to be sure of your particular property. See FAQ: What do I ask my County Zoning Agent?

If wanting to put a tiny house in our leased lot communities, we do require the home to be purchased from us. However, if you are buying a lot in our “purchase lot communities” you can buy from us, bring you own (must be approved by developer first), or stick build a home under 1200sqft.
