Off-Grid Living in Franklin, New Hampshire

I have not finished researching the town of Franklin yet. In New Hampshire your town sets zoning and local permits - contact the Franklin town office. Below is the New Hampshire state framework it inherits.

Is it legal to live off-grid in Franklin, New Hampshire?

There is no outright ban on living off-grid in Franklin, New Hampshire - it is possible, but the local rules are not all documented online. Zoning and land use are set locally and vary by area, putting a cabin, tiny home, or RV on raw land is set locally and vary by area, and building permits are set locally and vary by area. Plan around septic/wastewater (set locally and vary by area) and disconnecting from utilities (set locally and vary by area). Because these rules are set locally, confirm the specifics with Franklin before you buy land or build.

Read this before you act on anything below. This is my researched starting point for Franklin, not legal advice and not a guarantee. Rules change, and the deciding facts on any specific parcel (setbacks, perc results, overlay districts, deed restrictions, road frontage) live at the county or town office, not in any database. Before you buy land or build, confirm the current rules directly with the local zoning and health offices - the sources on this page tell you exactly who to call.

Franklin at a glance

Zoning & raw-land occupancy

Varies locallyZoning authority is delegated entirely to municipalities under RSA 674; the state doesn't zone land itself, though a 2025 state law now requires towns to allow at least one ADU per single-family lot. source

Dwellings, tiny homes & RVs

Varies locallyTiny homes on wheels are generally treated as RVs and confined to campgrounds/RV parks unless a town allows them as ADUs; foundation-built tiny homes go through the ADU process under RSA 674:71-73, town by town. source

Building permits & codes

Varies locallyThe state has adopted a building and fire code under RSA 155-A, but RSA 155-A:2, III reserves permit issuance and enforcement to counties, towns, and cities that have chosen to authorize it, so enforcement is a local decision. source

Septic & composting toilets

Varies locallyNH DES's Subsurface Systems Bureau regulates septic statewide under Env-Wq 1000; composting/portable toilets are acknowledged in DHHS guidance and campground law, but a clear statewide standard for permanent residential composting toilets was not confirmed, so ask your local health officer and DES. source

Greywater reuse

Unclear - verifyNo dedicated statewide DES rule for residential greywater reuse was found; existing DES water-reuse guidance covers treated municipal wastewater, not household greywater. Confirm directly with NH DES. source

Rainwater harvesting

Generally allowedNew Hampshire's adopted 2018 Residential Code (Ch. 29) and Plumbing Code (Ch. 13) allow rainwater harvesting for indoor non-potable uses; outdoor collection isn't separately regulated by the state.

Private wells & water rights

Generally allowedPrivate well construction is licensed at the state level by the NH Water Well Board under RSA 482-B, with siting rules (setbacks) and a required Well Record filing by the contractor after drilling; no separate state drilling permit is issued. source

Living disconnected from utilities

Varies locallyNo statewide law bans off-grid utility disconnection, but local health ordinances and subdivision regulations in some towns can require water/sewer hookups, so this depends on the specific municipality.
