Bike theft from backyards is common in Seattle, those strung-out on fentanyl will steal anything and trade for a few bucks at open-air markets with shoplifted liquor.

Bike hoists are now cheap and a good option if the garage ceiling is high enough. Garage door needs to stay closed, thieves will grab from an open garage.

Any rigid shed would need to have walls that cannot be cut easy with tin snips or kicked in, and a door that cannot be pried open with a prybar. Hard points for locking each bike to, would be a plus.
