Off-Grid Living in Juneau City and Borough, Alaska

If you're picturing raw land in Juneau where you can quietly park an RV or build a small off-grid cabin with no one checking in, I want to save you some heartache: Juneau is not unorganized Alaska. It's a unified home-rule municipality, meaning CBJ (City and Borough of Juneau) acts as both city and borough and runs one areawide planning and zoning code, Title 49, that covers essentially the whole borough. That's a real departure from the "no zoning" reputation a lot of rural Alaska has.

Zoning. Every parcel in CBJ sits in a zoning district (residential, rural reserve, commercial, etc.), and what you're allowed to put on the land is governed by CBJ's Table of Permissible Uses under Title 49. You can't assume raw land equals a blank slate; check the zoning district first.

Dwellings, tiny homes, RVs. CBJ code compliance actively goes after people using an RV as a permanent living unit outside a licensed RV park, so that's off the table as a long-term off-grid housing strategy. Tiny or accessory dwellings are possible through CBJ's ADU pathway, but they still have to meet zoning dimensional rules, and if the lot isn't on city sewer you'll need a letter from the state Department of Environmental Conservation (DEC) confirming your onsite wastewater system is adequate.

Building permits. CBJ has locally adopted the International Residential/Building Codes with its own amendments, and no development work happens without a valid CBJ permit, processed through the CBJ Community Development Department.

Septic and greywater. This is where it shifts to the state level: Alaska DEC, not a CBJ septic office, runs the onsite wastewater (OSDS) permitting program that Juneau falls under. CBJ's own zoning/subdivision review just wants proof the soil works for onsite disposal, or an approved alternative, before it'll sign off. Greywater has no CBJ-specific rule I could find; it rides on the same statewide DEC framework (18 AAC 72) as everywhere else in Alaska.

Rainwater catchment. Honestly unclear. I couldn't find a CBJ or DEC page nailing down permit requirements for rainwater harvesting, potable or not, so treat this as unresolved and ask before you build a system you're relying on.

Wells. No CBJ-specific well ordinance turned up. Private wells fall under the state's DEC construction standards and Alaska DNR water-rights rules. CBJ's municipal water utility is a separate thing entirely and doesn't touch private wells.

Living off-grid generally. The good news: nothing in CBJ code forces every parcel onto municipal water and sewer. You can disconnect, but you still need DEC-approved wastewater documentation and CBJ building/zoning sign-off. It's "permitted with conditions," not a free-for-all.

Bottom line: Juneau blends state DEC authority (septic, wells, greywater) with real, actively-enforced CBJ zoning and building rules. Confirm specifics with the named offices before you commit to a plan.
