Davis was recently named one of the best places to retire by Forbes magazine - so although there are not a lot of dedicated "senior" communities - it is fairly sought after for retirees. In Sacramento there is Heritage Park in North Natomas (gated senior community - detached homes) and Sun Meadows also gated also detached homes. Heritage Park would be closer to Davis.
