Off-Grid Living in Peru, Maine

I've been digging into what it actually takes to live off-grid in Peru, Maine, a small Oxford County town, and here's where things stand based on what I could confirm directly with town and state sources.

Zoning. Peru is not unzoned. The town, per its own "Policies & Ordinances" page, runs a Land Use Ordinance, a Shoreland Zoning Ordinance, a Noise Ordinance, and a handful of others. Shoreland Zoning follows state-mandated minimum guidelines but is enforced locally, meaning your first call for anything near water should be the town's code enforcement officer. Outside shoreland areas, the Land Use Ordinance still governs what you can do with raw land, so don't assume rural Maine means no rules.

Dwellings, tiny homes, RVs. I couldn't pin this down. I didn't find Peru-specific language on tiny homes or RVs as permanent residences, and a third-party permit-aggregator site hinted at exemptions "per local Land Use Ordinance" but that's not something I can verify from an official source. Call the Town Office and ask to see the actual ordinance text before you plan around this.

Building permits. Peru sits well under Maine's 4,000-population threshold that triggers mandatory statewide building code (MUBEC), so the town administers its own permitting under the Land Use Ordinance. A Building Permit Application is listed among the town's official forms, so permits are required locally even without full MUBEC adoption.

Septic and composting toilets. This one's solid: septic systems are permitted through the state's HHE-200 process, administered locally by a Local Plumbing Inspector (LPI) that the Town Office appoints. The town itself points residents to the state's septic records database, searchable by choosing Peru from a dropdown. Any subsurface wastewater system, composting toilet setups included where applicable, needs to go through the LPI.

Greywater. No Peru-specific restriction turned up. Greywater disposal falls under that same state HHE-200 permitting framework via the LPI. I didn't find town text adding extra restrictions on top, but that doesn't mean none exist, so it's worth confirming.

Rainwater harvesting. Not confirmed. I found no Peru ordinance or state rule specifically addressing rainwater catchment.

Private wells. No Peru-specific well ordinance surfaced. Well construction defaults to Maine's Water Well Commission rules at the state level, with no additional town permitting requirement identified.

Utility disconnection. Not confirmed directly. The Land Use and Shoreland Zoning Ordinances may touch this indirectly through setback, building, or septic requirements, but I found no explicit Peru rule on living unhooked from the grid.

Bottom line: Peru gives you more room to build your own setup than a MUBEC town would, but "zoned" is zoned, so the Land Use Ordinance and the Town Office's code enforcement officer are your real gatekeepers, not just word of mouth about rural Maine being a free-for-all.
