Off-Grid Living in Wrangell City and Borough, Alaska

I've been digging into Wrangell City and Borough, Alaska, because it's an interesting outlier: this is a unified home rule city-borough, meaning it actually exercises zoning and building authority across the whole borough, unlike a lot of unorganized Alaska where "off-grid" often means "no rules at all." That cuts both ways for off-gridders here.

Zoning: Wrangell adopted a full Title 20 zoning code (Borough Assembly update passed January 2013), and it created something genuinely useful for off-grid folks: a Remote Residential Mixed-Use (RMU) district covering outlying, off-road settlements like Meyers Chuck, Union Bay, Thom's Place, Olive Cove, and Wrangell Island East. The RMU district exists explicitly for low-impact, off-utility living. Land not otherwise classified defaults to single-family or RMU zoning until the borough amends it.

Dwellings: Manufactured/mobile homes have age and width rules outside RMU and mobile home parks (built after 1979, 24+ feet wide, permanent foundation, per Wrangell Municipal Code standards). In RMU, density rules loosen considerably, and multiple principal structures are allowed per lot at a lower threshold than elsewhere in the borough.

Building permits: Here's the big one. Wrangell has adopted the Uniform Building Code (1997 edition, with local amendments) borough-wide, and a permit is required for most construction. But Title 18's building code provisions do NOT apply to noncommercial structures inside the RMU district. Instead, noncommercial builders there file a proposed development application instead of a standard building permit. Commercial builders in RMU still have to comply fully.

Septic and greywater: The borough defers entirely to the Alaska Department of Environmental Conservation (ADEC) for wastewater, septic, and (by extension) greywater systems. There's no separate Wrangell ordinance I found; DEC's state-level rules (18 AAC 72) govern, including prior notice to DEC before installing a conventional system, and engineer sign-off for more complex ones.

Rainwater and wells: I found no Wrangell-specific ordinance on rainwater catchment, so I'd treat this as state-baseline territory (unconfirmed locally). Same goes for private wells: the borough water department manages municipal reservoirs, but I couldn't confirm a distinct local well permitting process, so state DEC well-construction and separation-distance rules are what would apply, per my research.

Utilities: Wrangell has actually planned for disconnected living rather than just tolerating it. The RMU district's stated purpose is to protect remote settlements from being forced into costly grid extensions and intensive development standards, while state DEC rules on wastewater, wells, and water rights still apply no matter your grid status.

Bottom line: Wrangell is unusually off-grid-friendly for a home rule borough because of the RMU district, but you're still working within a real zoning and permitting system, and state DEC controls your water and waste questions either way.
