Off-Grid Living in Auburn, New Hampshire

I've been digging into what off-grid living actually looks like in Auburn, New Hampshire, and the short version is: Auburn is a fully zoned town, and that zoning, layered on top of New Hampshire's state building and septic rules, creates real friction for anyone hoping to live simply and disconnected out here.

Zoning. Auburn has an adopted Zoning Ordinance, administered by the town's Building Inspector/Zoning Officer, with a Zoning Board of Adjustment handling variances and appeals, and a Planning Board overseeing site plan and subdivision matters. The town is divided into residential, industrial, and other districts. I didn't find language that directly addresses "raw land occupancy," like simply living on undeveloped land without a conventional structure, so that would come down to a case-by-case call from the Building Inspector or ZBA. Junk accumulation and nuisance provisions are also enforced locally, referencing the state statute RSA 236:112.

Dwellings, tiny homes, RVs. This is one of the tighter spots. Auburn restricts overnight parking of RVs in residential zones outside of approved site plans, per state RSA 259 as adopted locally. Accessory Dwelling Units are allowed but capped in size (I've seen figures like 950 square feet or a 40% expansion cap referenced in the ordinance, whichever is smaller), and at least one version of the ordinance appears to prohibit detached ADUs entirely. Because the ordinance has been amended recently, I'd confirm the current ADU rules directly with the Auburn Planning Board before making plans.

Building permits. Auburn requires building permits, issued and inspected locally under the state building code (RSA 155-A). The Building Inspector's office handles applications and inspections.

Septic and composting toilets. Septic design and approval in Auburn runs through the state, specifically the NH DES Subsurface Systems Bureau, with plans sometimes routed through the town. Importantly, Auburn's rules (echoing state plumbing code logic) say any structure connected to a water supply, including a well, must also be connected to a wastewater disposal system. That means you likely can't rely on a composting toilet alone once you're on a well, unless the structure has no connected water supply at all. Composting toilets aren't separately addressed in what I found for Auburn.

Greywater and rainwater. I found no Auburn-specific ordinance on greywater reuse or rainwater harvesting. Both appear to just inherit whatever ambiguity exists at the state level, so I'd call this unclear rather than settled.

Wells. Well construction follows state licensing rules; I didn't find an Auburn-specific well ordinance. But again, the water-supply-to-wastewater-disposal linkage matters here for anyone hoping to use a well without a full septic system.

Utility disconnection. There's no outright "off-grid ban" that I found, but between the water/wastewater connection rule, RV parking restrictions, and tight ADU limits, ad hoc off-grid living arrangements face real practical constraints, enforced locally by the Building Inspector and ZBA.

My honest read: Auburn isn't hostile to off-grid living in principle, but it's not a permissive gap either. Plan on permits, plan on septic approval through the state, and call before you buy land or move a structure onto it.
