- What is the minimum dwelling size in this zone?
- Has the county adopted Appendix Q of the IRC for tiny houses?
- What does a septic permit need here: perc test, minimum lot size, setbacks?
- Does a well need a permit, and is there a minimum lot size for one?
- Does the lot have legal road access, and who maintains the road?
Get answers in writing when you can. Rules change, and a phone answer won't help you at a permit hearing.
