Off-Grid Living in Bow, New Hampshire

Bow, NH is a zoned town with active building and septic enforcement tied to state code, but tiny home/RV rules, greywater, and utility-disconnection policy aren't clearly spelled out locally. Anyone planning off-grid living there should confirm specifics with the Community Development and Building Departments before buying land.

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

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

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.

I've been digging into what off-grid living actually looks like in Bow, New Hampshire, and the short version is: Bow is a zoned town with active planning and building departments, so you're not going to find a legal loophole here to just set up quietly on raw land. Here's what I found, dimension by dimension.

Zoning. Bow has a full Zoning Ordinance (Articles 1-14, amended periodically), a Zoning Board of Adjustment, and a Planning Board, all authorized under New Hampshire's enabling statutes. The town regulates land use, setbacks, building size and height, and separates districts like Business Development, Bow Mills Mixed Use, and South Bow Mixed Use. If you're eyeing a parcel, you need to check which district it's in before assuming you can do anything off-grid there.

Dwellings, tiny homes, RVs. I couldn't find Bow-specific ordinance language addressing tiny homes on wheels or RVs as permanent dwellings. The town does have accessory dwelling unit (ADU) guidance, including a New Hampshire Housing ADU guide, but that's a different animal from an RV or THOW. Treat this as unconfirmed and call the Community Development office before you commit to a plan.

Building permits. Bow's Building Inspector enforces the State of New Hampshire Building Code locally, and the Building Department issues permits, does inspections, and signs off on Certificates of Occupancy. This is a real, active permitting process, not a rubber stamp.

Septic and composting toilets. Septic systems in Bow fall under New Hampshire DES rules (Env-Wq 1000), which require plans from a state-permitted designer and both Approval for Construction and Approval for Operation from DES, with the town sometimes weighing in too. I didn't find a Bow-specific composting toilet ordinance, so that's a gap to fill in with the Building Department directly.

Greywater. I found no Bow-specific greywater ordinance, and New Hampshire doesn't appear to have a dedicated state residential greywater rule either. This one is genuinely unclear, so ask before you build a greywater system expecting it to be legal by default.

Rainwater harvesting. Nothing in Bow's rules seems to prohibit it, and it would fall under the state Residential/Plumbing Code as enforced locally by the Building Inspector. I'd call it permitted, with the caveat that plumbing tie-ins may need inspection.

Wells. Wells are governed by the state Water Well Board, and Bow's septic application process asks about water supply type, including well radius and easements. I didn't find any additional town-level well ordinance.

Utility disconnection. I found no explicit Bow rule requiring you to hook up to utilities, but site plan review, subdivision rules, and conditional use permits for wetlands or aquifer protection could indirectly limit where and how you go off-grid. This is a "check before you assume" situation.

Bottom line: Bow isn't hostile to off-grid living, but it is a fully zoned, actively enforced town, and several key questions (tiny homes, greywater, utility disconnection) just aren't spelled out in what I could find. Confirm directly with the town before you invest money in land or a build.

FAQ

Common questions about off-grid living in Bow

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

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

Can I put a tiny home or RV on land in Bow, NH as a permanent residence?

I couldn't confirm a specific Bow ordinance covering tiny homes or RVs as dwellings. The town does have ADU guidance, but that's not the same thing. Call the Community Development office before you plan around this.

Do I need a permit to install a septic system in Bow?

Yes. Septic systems statewide, including in Bow, are regulated by New Hampshire DES under its subsurface rules, and plans must come from a state-permitted designer, with DES approval needed before construction and before use.

Is greywater reuse legal in Bow?

This is genuinely unclear. I found no Bow-specific greywater ordinance and no dedicated state residential greywater rule, so I'd confirm directly with the town's Building Department before setting one up.

Can I live completely off-grid without hooking up to water or sewer utilities in Bow?

No explicit town rule requires utility hookups, but zoning, subdivision, and conditional use permit requirements for wetlands or aquifer protection could affect where you can do this. Not confirmed as a blanket right, so check with the town first.
