This office is where you would call to make sure you are able to do what it is you set out when buying your property. Even if your property does not have CCR’s, an association, or additional restrictions, the property owner still must abide by federal, state, and county regulations. A quick phone call can often give you all of the information you need.
Great questions to ask would be “does the county allow RV’s on the property and for how long?”, “Can I get a conditional use permit for RV living while building?”, “Is hunting allowed on my property?”, “Do I need to drill a well for water or can I use a holding tank?”, “What kinds of septic tanks are allowed here?”, “How many homes can I have on this property?”, “Are manufactured, mobile, or modular homes allowed”?
Sometimes a property is zoned one way and you can apply for a change in that zoning. There is usually some sort of precedent they can look up, but a good example is if it is zoned residential and you want the zoning changed for commercial use or perhaps you have a solar or wind project you are interested in and want to know the steps needed.
Another use for this department is to get the information about subdividing larger tracts of land. For example, if you have 640 acres (1 section of land or 1 square mile by 1 square mile), then you can subdivide that land into 16 x 40 acre parcels and sell them individually. Of course you can subdivide them down even more or keep them larger, but you get the idea. Every state and county have different requirements for subdividing so if this is what you want to do then I highly recommend contacting the County planning department.
