I gather you bought a Home either on the Court steps or For Sale by Owner.
If you bought it off the MLS then you would have signed off on HOA documents and if there was
a neighborhood Pool or a HOA, then you would have been made aware via your Agent.
If you have lived in the home for Years and are not aware then Relax there is none,
otherwise you would have been in default and Foreclosed on by your HOA.
Now certain parts of 95116 are in City of San Jose jurisdiction Enforcement of Garbage and Utility collection. As home owners have not been Paying, then the City uses "eminent domain", otherwise you can have Diseases and Plague spreading.
When neighborhoods in Silicon Valley go bad, it is very simple, we cant just let it get worse.
Then the City moves in, and by eminent domain sets up, a 10 year Policy, you maybe part of that policy.
Relax, San Jose is not the only one who does it. Actually, there are Counties who use
the Power of Government call Eminent Domain.....click on link..
You need to check with your Realtor or with the City now if you bought on Court steps.
Hope it is crystal clear.
Perhaps you want to know if your home has CC&R's? This could be the case which doesn't necessarily require an Association.
A good rule of thumb would be if there are common areas, such as parks, streets, club house, etc. that is a benefit to you but are maintained by someone else, then it most likely belongs to an association.
