Subdivision and MHRC Regulations and Documents

Subdivisions of land must be platted in accordance with the Subdivision and MHRC Regulations adopted by Gillespie County. 
Please note that the County's adopted minimum lot size for subdivisions served by well and OSSF is 6 acres per lot, with a maximum density of the parent tract divided by 8. 
Example: I have 15 acres and want to subdivide. The tract cannot be subdivided because the maximum density requirement is not met. 
Example: I have 30 acres and want to subdivide. The maximum number of lots is 3 lots (30/8=3.75), and each lot must be at least 6 acres. 

Land that is separated into two or more spaces for the installation of manufactured homes for rent is considered a Manufactured Home Rental Community (MHRC). A manufactured home may include any type of structure that is fabricated in such a way to be re-assembleable or otherwise moveable in whole or in parts, including but not limited to manufactured homes, mobile homes, RV’s, tiny homes, shipping containers, etc. A MHRC application must be submitted and approved by the County Engineer prior to the start of construction.
