Off-Grid Living in Sitka City and Borough, Alaska

Sitka is a unique case in Alaska: it's a unified home-rule city-borough, which means it has borough-wide zoning and building authority that most of "unorganized" rural Alaska simply doesn't have. If you're picturing Sitka as a lawless frontier for off-grid living, I want to correct that up front. There's real municipal oversight here, layered on top of the State of Alaska's rules for wells and septic.

Zoning and raw land. The City and Borough of Sitka (CBS) administers area-wide zoning under Title 22 of the Sitka General Code, through its Planning Department. What you can do with a piece of land, setbacks, allowed uses, depends on the zoning district, so don't assume raw land is a blank slate. Confirm your parcel's zone with Planning before you make plans.

Dwellings, tiny homes, RVs. Sitka actually passed a specific tiny-house ordinance (amending Titles 6, 19, and 22) that gives "tiny homes on chassis" their own legal category, adopts IRC Appendix Q construction allowances for homes under 400 square feet, and permits tiny homes on foundations in manufactured-home parks. Putting a tiny house on chassis on an individual lot requires a conditional use permit from the Planning Commission, and any tiny home, foundation or movable, needs a building permit and inspections. Standard RVs are treated like RVs everywhere: you legally cannot live in one year-round in Sitka.

Building permits. CBS enforces its own adopted building code (including the International Existing Building Code with local amendments) through the Building Department. A permit is required before most construction, alteration, or demolition work, per the code's Section 106.

Septic and greywater. I didn't find a separate CBS septic ordinance; Sitka defers to the State of Alaska DEC's statewide onsite wastewater rules (18 AAC 72). A licensed engineer handles design/certification in more complex cases. Greywater appears to fall under this same state framework, but I couldn't confirm whether CBS's plumbing code adds anything on top, so check with the Building Department.

Rainwater catchment. No CBS ordinance on residential rainwater harvesting turned up in my research. DEC only mentions rainwater in passing, advising that roof and driveway runoff be kept away from septic drainfields. Whether Sitka's building code separately touches catchment systems is not confirmed, call the Building Department to be sure.

Wells and water. Sitka runs its own municipal water utility (Blue Lake sourced) under Title 15, and connecting requires an application through the utility. Outside that service area, private wells fall under the state DEC's standard construction and separation rules; no separate local well ordinance was found.

Off-grid utility disconnection. I found no CBS ordinance mandating hookup to municipal water, sewer, or electric for private property. That said, state DEC rules for septic and wells still apply no matter your grid status. Treat "off-grid is fine here" as plausible but not confirmed at the ordinance level.
