Not normally, but it may depend upon the area.
HOA = Hown Owners Association; typically a group in a development that was created at one time; a subdivision, a new township, village, etc. to define, and enforce neighborhood policies.
C/C = Condo/Coop Fees; Condo - typically a building, subdivided into separate living quarters that have community concerns and community amenities; such as common grounds, common walls, roofs, pools, fixtures, elevators, etc; that require fees for maintenance. (also cover management fees and services. Coop - typically a building, owned by a Closely held Private Corporation, for which people buy shares of the Corporate Stock, which entitiles them, as stockholders to live in separate quarters in the building(s) owned by the Corporation. Their fees include the tax payments, since the Corporation is the owner of record.
In these cases, your fees are determined, most often, by a pro-rated share based upon relative ownership; either area, volume, or value.
It would be possible, I suppose for a condo to exist in an area that also has an HOA, and that fees would need to be paid for both, although, it would seem to me to be, more likely, a case of 'mistaken identity' where someone mistakenly listed an amount in two separate places.
You should ask the seller, before making a commitment, though. Your agent can do that for you.
