Maintenance will work! Anton has asked Callaghan to basically outright rebuild some of his mechanical systems because he feels Tony is too excitable easily distracted by Stark Industries current city climate. Things like the oven and the lights and the electrical wiring is still a thing for Tony to have looked into, though!

Cooking is also fine--Anton will pretty much just go 'when you make meals for yourself, if you can make extra and put it in the fridge for anyone to have, I'll consider it a fair trade'. So nothing really regimented.
