Check zoning and land use rules before you buy

Before you commit to any land, find out from the local authority whether you can legally build and live off-grid on it. Land use rules differ widely between countries, regions and even neighbouring districts, so a plot that is fine in one place may be unusable a few kilometres away.

How

  1. Identify the authority that controls land use for the exact parcel: for example a county or city planning and zoning department in the US, the local planning authority (council) in England, or the local council under state planning law in Australia.
  2. Ask for the zoning or land use designation of the parcel and a copy of the rules that apply to it, including any overlays (flood, wildfire, heritage, conservation, agricultural protection).
  3. Ask: is a permanent dwelling allowed here at all, and is there a minimum dwelling size or minimum lot size?
  4. Ask: is full-time occupancy of a home with no grid power, mains water or public sewer allowed, and are there any conditions (for example approved private well and septic systems)?
  5. Ask: is there any rule that requires connection to public power, water or sewer, for example if a main runs within a set distance of the property? Example (US, Washington State): when an on-site sewage system fails and adequate public sewer is available within 200 feet, the local health officer must require connection if the utility allows it, unless a conforming replacement system can be permitted. Get the answer for your parcel in writing.
  6. Ask: what permits are needed for a private well or borehole, a septic or other on-site wastewater system, and a standalone solar or other power system, and who issues each one?
  7. Ask whether temporary living on site (caravan, tiny house, cabin) is allowed during construction and for how long.
  8. Check private restrictions too: title deeds, covenants, easements, and homeowner association or estate rules can ban things the public rules allow. A property lawyer or conveyancer can review these.
  9. In England, the Planning Portal interactive guide and your council's pre-application advice service are the usual first stops; some councils also issue a formal Lawful Development Certificate for proposed works.
  10. Make the land purchase conditional on these answers where your local purchase process allows it, and take advice from a local property lawyer before you sign.
