Condos are typically property where you own a specific part of a larger property (a legally recognized/identified “interest”) plus an agreement to maintain everything else that isnt explicitly exclusively yours (“common space”). The condos I’ve own show true ownership share - even the land (though no distinct part, just fractional ownership).
Single family homes are different in the sense that it’s one legally defined property where 100% of it is for the exclusive use of the owner. HOAs can include a group of individual properties plus (or not) common space.
Your description of co-ops reminds me of TICs (tenancy in common) in CA. The property is viewed as one “unit” although it may be subdivided by tenants through a separate agreeemnt. Typically in TICs you buy an entire building and have a separate agreement that lays out what is exclusive and what is common. But the city sees it as one property in its entirety with multiple owners.
