Most families expect the hard part of hiring home help to be choosing the agency. The house often decides more than that. A visit before the first shift shows you where the helper will walk in, where things are kept, and which rooms are in use, so you can close the gaps while there is still time to do it calmly.
Local option: New Plan Care gives families in the St. Louis area in-home help so a parent can stay home: companionship, help with bathing and dressing, meals, and overnight care. Call (314) 405-0887.
Walk the route the helper will actually use
Stand outside at the time of day the visits will happen. Note where a car can park, how far the walk is to the door, whether the path is lit after dark, and whether the steps or threshold are easy to see. Confirm how the helper will get in. A lockbox, a keypad, a key held by a neighbor, and a key under a mat each raise different questions, and the agency should have a written answer for whichever arrangement you choose.
Inside, mark the paths and the clutter
Walk the rooms the helper will enter for the tasks you have listed, and mark anything in the way: loose rugs, cords across the floor, boxes stacked in hallways, a chair that must be moved to reach a cabinet. Check which doors swing the wrong way, where the light switches are, and whether someone carrying laundry or groceries can reach the kitchen and bathroom without stepping over something. A room-by-room list is in the home safety guide, which is worth reading before you walk.
Decide what is off limits and say it out loud
Every household has drawers, rooms, and items that are not part of the helper's job. Make that list before the first day, not during a shift. Include the home office and any papers about money, locked cabinets, tools, valuables, and personal belongings. Write each boundary on the same page as the task list so the agency can read it back to you. A helper who knows the limits in advance is less likely to cross them by accident, and you are less likely to correct it in front of your parent.
Confirm the supplies and the emergency basics
Check that the house has what the visits need: working lights in every room in use, a phone the helper can use, a list of people to call with their numbers in a visible spot, a flashlight, and the locations of the water shutoff, the breaker panel, and the thermostat. Ask whether the agency expects the family to stock gloves, cleaning supplies, or trash bags, or whether the agency brings its own, and note the answer in writing. Do not leave that question for the first shift to answer.
Ask the agency to do the walk with you
Schedule the pre-start visit with the agency's supervisor, not only the person who will be assigned. Ask the supervisor to walk the house with you, point out what they would change, and explain what they will record. Then ask whether the visit is done alone or with a family member present, whether you will receive a copy of the notes, what change in the house or routine would bring them back for another look, how you will be told if a room or task is not workable for the helper, and which items you need to provide versus which the agency will bring. Any health questions go to the family's doctor, not to the visit.
Put the findings in one written list
Gather your notes from the route, the rooms, the boundaries, and the supplies onto one page. Each line should name the item, the person responsible for fixing it, and the day it will be done. Keep the page where the helper will see it on day one, and add the agency's answers beside your own. If an item is still open, do not start the first shift until someone owns it.
Local resources for the changes
If the house needs work you cannot do yourself, ask the agency what it expects from the family and then contact the area agency on aging that serves your county. Those offices can explain general options for home changes in the St. Louis area, so you do not have to search for each program on your own.
