Off-Grid Living in Pembroke, Maine

I've spent a while digging through what official records exist for Pembroke, Maine, a small town on Cobscook Bay in Washington County, and I want to be upfront: this is one of those towns where the paper trail is thin. That's not unusual for small Maine towns, but it does mean you'll need to call the town office to fill in gaps I couldn't confirm from official sources.

Zoning. Based on Pembroke's own document listing (hosted through the University of Maine's Digital Commons town records collection), the town appears to have only three local ordinances: a Building Permit ordinance, an Emergency Management ordinance, and a Shellfish Conservation ordinance. I did not find a general/base zoning ordinance. That said, Pembroke has tidal shoreline on Cobscook Bay and frontage on the Pennamaquan River, and Maine's Mandatory Shoreland Zoning Act requires every municipality with water bodies to have shoreland zoning regulating structures near the water, enforced locally. I couldn't locate Pembroke's specific shoreland zoning map or ordinance text online, so treat that as unconfirmed and ask the town office directly if you're anywhere near water.

Dwellings, tiny homes, RVs. I found nothing Pembroke-specific addressing tiny homes, RVs, or seasonal versus permanent dwelling rules. This is genuinely unclear from available sources.

Building permits. Pembroke does have its own Building Permit ordinance, per the town's document list. Statewide, Maine's Uniform Building and Energy Code (MUBEC) is only mandatory for towns above a population threshold, and Pembroke's population (around 788 residents) is well under that, so MUBEC may or may not be locally adopted. Confirm with the town office.

Septic and composting toilets. Every Maine town is required to have a Local Plumbing Inspector (LPI), appointed by the town and licensed by the state, who administers septic permits under the state's Subsurface Wastewater Disposal Rules. This is a state-set framework administered locally. If your property is in the shoreland zone, Maine statute also requires a wastewater system inspection at the time of property transfer.

Greywater. No Pembroke-specific rule found; the state's standard greywater permitting process, run through the LPI, should apply here.

Rainwater harvesting. Not confirmed either way, no ordinance found addressing it.

Private wells. No town-specific rule found; standard Maine private well framework applies.

Off-grid/utility disconnection. Nothing explicit banning or permitting this locally. Any real-world requirement would come indirectly through the building permit and septic/LPI processes described above.

My honest bottom line: Pembroke looks like a town with minimal ordinances, which can be good news for off-grid setups, but shoreland zoning and building/septic permitting still apply and the specifics aren't published online. Call the town office before you commit to a plan.
