A misspelling or variant plural form intended to represent multiple condominiums (though not standard English).
This appears to be a non-standard or obsolete attempt at creating a Latin plural form of 'condominium,' but English condominiums are simply pluralized as 'condominiums.'
This isn't actually a real word in standard English—it's likely a historical spelling attempt or perhaps a word from another language; modern English simply uses 'condominiums' as the plural.
