It depends on the house and systems in use. You could include all sorts of things. I use a monthly spreadsheet to keep track of it all.
- yard, trees, gutters, fertilizing, weed control
- roof, gutters, drainage
- patio, deck, driveway, sidewalk cleaning or power washing
- sump pump, septic, water well, pool, sauna, jacuzzi
- fireplace(s), chimney(s)
- refrigerator coils, clothes washer filter, furnace service
- winterization
- spring cleaning - move all furniture, empty all cabinets, windows
The list goes on and on...
