If you're an HOA
The §528 basics
Most HOAs elect IRC §528 and file Form 1120-H. To qualify, at least 60% of the association's income typically must come from member assessments (the "60% income test"), and at least 90% of expenditures must go to community purposes (the "90% expenditure test"). At least 85% of the property must be used as residences (the "85% residential-use test").
What changes when you list space with hoastnow
Booking revenue from outside brands is "non-member income" for §528 purposes. It counts against the 60% income test. For most HOAs receiving healthy member-assessment income, occasional brand activations are well within the headroom — but boards with thin assessment income should run the math before listing.
What to look for in your governing documents
CC&Rs and bylaws often address commercial use of common areas. Look for clauses about (a) board authority to enter rental contracts, (b) owner-notice or owner-vote requirements above certain revenue thresholds, and (c) restrictions on the kinds of activities permitted in shared spaces.
