Off-Grid Living in Tilton, New Hampshire

Tilton, New Hampshire is not the kind of place where you can just buy a few acres and disappear off the grid without a conversation with Town Hall. Tilton is a zoned town, with a Zoning Regulations document (last comprehensively updated March 2021) that lays out districts, dimensional standards, and a chart of permitted uses by district. That means how you can occupy raw land, whether living in a tent, RV, or tiny structure, depends on which zoning district your parcel sits in. I haven't found anything suggesting Tilton is one of those "unzoned, do what you want" New Hampshire towns, so don't plan around that assumption.

On dwellings specifically, the zoning ordinance includes an appendix addressing manufactured housing, mobile homes, and recreational vehicles as a distinct use category. That tells me Tilton does have specific rules for these housing types, but I wasn't able to pull the exact permitted-use and placement details in this research pass. If a tiny house on wheels or a mobile home is part of your plan, that appendix is exactly what you need to read, or better, ask the Land Use Office to walk you through it.

Building permits and inspections in New Hampshire are handled locally rather than by the state, and in Tilton that falls to the Land Use Office at Town Hall. I don't have confirmed fee or process specifics, so treat any numbers you hear secondhand with caution and confirm directly.

Septic is where New Hampshire's state role is clearest: if your structure has any water supply connected to it, NH DES's Subsurface Systems Bureau requires an approved Individual Sewage Disposal System (ISDS), designed and applied for through a licensed septic designer. The only real exception is a structure with no water supply at all. Composting or incinerating toilets aren't permitted by DES, but DES rules do touch them, and the agency explicitly tells owners to check with their town's Local Health Officer before installing one. In Tilton, that health officer function runs through the Board of Selectmen and Land Use Office.

Greywater reuse doesn't appear to have a dedicated statewide NHDES rule, and I found no Tilton-specific ordinance either, so I'm calling that unclear rather than guessing. Rainwater harvesting for non-potable indoor use is allowed under state plumbing code, and I found no Tilton rule narrowing that. Private wells fall under the state Water Well Board, with no added Tilton restriction on the books that I could locate, though the town's own water utility, the Tilton-Northfield Water district, serves parts of town.

Finally, on going fully off-utility: I could not find a Tilton ordinance mandating water or sewer hookup for occupancy, but the town does run its own Sewer Department, so this is genuinely a "call and ask" situation rather than a settled yes or no.
