You still need to cover the 7 basics: Water, Food, Shelter, Fire, Knife, First Aid, Signalling.

Shelter may seen easy since you are in your home. The problem may be that most homes are not designed to work well without electricity. Rooms are often vary dark because of too few or too small windows. Homes may only have a single fireplace that is designed to look pretty but is not terribly efficent for cooking or heating an entire house.

Also think about common problems that might happen to cause you to shelter in. Severe weather has shutdown the roads and community. Weather also freqeuently knocks over trees causing damage to homes. You will need materials to at least keep out wind and water. Sheet plasic, duct tape, box of roofing nails, staple gun and hammer will seal up most holes in homes temporarily.
If you have a package or two of matching shingles, you might even be able to make a permanent repair to your roof.

Think about sealing off most of your house and living in just a few rooms. It will make heating the space easier. You will need an alternate heat source like a fireplace, kerosene heater, or propane heater. Fireplaces heat that room relatively well but not usually the other rooms. A wood stove or heater usually requries a permanent installation prior to event. A portable kerosene heater can be effective at heating a room and some can be cooked on. Kerosene stores indefinely with no degradation and is relatively inexpensive. There are two models of propane heaters APPROVED for indoor use. MR Heater and Buddy heater. About $100 US. Propane stores indefinetly with no degradation. Make sure you have a battery operated CO2 detector in case the heating device works improperly. Also might open a window just a bit to provide fresh source of O2. Some people even set up their tents inside their houses to make best use of body heat while sleeping.

If you are prepared for outdoor survival, you can survive indoors. Just move out to your backyard, deck, patio and perform some tasks outside. Others you just need to prepare by stocking extra supplies like bottled water, 30 days of non-perisable food, batteries, candles, matches, extra blankets.
