Full Breakdown
Anchorage's zoning code counts a tiny home as a "relocatable dwelling unit": defined in AMC 21.15.040 as a manufactured home, mobile home, tiny home, or other small dwelling that can be moved and certified safe for occupancy by HUD or the Building Official. Under AMC 21.05.070E.4, relocatable dwelling units may be used as an accessory dwelling unit only if placed on a permanent foundation; simply parking one on a lot as a wheeled or skid-mounted living space doesn't qualify. Outside a permitted relocatable dwelling unit community, a mobile tiny home can only sit on a lot temporarily as a construction-period dwelling under separate provisions.
Violations & Fines
Code enforcement can order removal or require the unit anchored to a permanent foundation before it counts as a lawful accessory dwelling.
