Great question. I have not run across any developments over the years. If it is any help there is an indoor pool in Hayward called the Hayward Plunge and Fremont Swim School that have indoor pools. Good luck.
Hi - well I asked around - and truely I am not finding an HOA which meets your request. Without sounding contrite would a one year membership at a Health Club work in conjuction with the Condo of your Dreams?
You pose a request that honestly I haven't heard often in California - I am not sure which Condo community's offer fully enclosed pools. We enjoy lovely weather for so many months of year that my I believe the HomeOwner Associations felt that a fully enclosed pool was an expense they rather not encumber. I'd be curious to know if someone else is familiar with an HOA which can meet your request. Good Luck
