Benevolent landlord
Similar in name to Benevolent dictatorship and Benevolent Dictator For Life. The idea is that a person buys a property, and rents it out to a group (like Skullspace) on intentionally favourable terms.
For transparency reasons, it's a good idea to take a "trust, but verify" approach to B.L. situations and document the extent of the benevolence -- especially if folks are considering contributing volunteer labour to leasehold improvments or are concerned about the effects a future move or high rents could have on the organization.
