Define "unlocked". I live in an apartment so no patio but when I lived in a home if I was on the patio the front door was locked.Sound advice. Basic rule of thumb for me is if house is unlocked and alarm off( like right now sitting on back patio enjoying the weather) I am carrying. It helps if you have options for different carry situations. I have some pistols rigged with holsters for IWB carry during summer with only a light t shirt; others rigged with OWB holster for winter carry under a jacket; and lastly, small pocket guns in sticky Remora holsters that I can simply tuck into a pocket or waist band of gym shorts/sweats without a belt( like right now chilling on back patio in "lounge lizard" shorts).
