How to keep common areas usable for everyone
Assign storage for shoes, coats, tools, packages, and shared supplies. Set a reset rule for the kitchen, living room, and dining table. Work setups and hobby projects should pack away or have agreed hours.
Ask before rearranging furniture, leaving items overnight, or hosting a group. Keep routes to doors, bathrooms, and kitchen appliances clear.
Usable common areas reduce conflict because no one must negotiate access to their own home.
