Three items (among a number of others) you shouldn’t keep in a garage:
Refrigerator—when the garage is cold, the compressor won’t run long enough to cool the freezer properly and when it’s hot, money and energy are wasted;
Gasoline or Oil—vapors are flammable.
Paint—wide temperature swings can damage paint.
So many properties I see lack sufficient smoke detectors or have them in the wrong place or are missing carbon monoxide detectors. If you are unsure of today’s code, pls call or email me for details. The information is on the web but not always as easily interpreted as one would hope.
