Do you charge your adult child room and board?

We do not. However, my son takes on a fair amount of responsibility for chores. We work quite well together.

He will see things need to be done and do them. He is my bathroom cleaner. He takes care of the litter boxes.

I dread the day he flies from the nest. 

Editted to add: If he weren’t actively helping, he would definitely be charged rent. 

DH's parents always said first month is free after that you pay rent. My feeling is if they're working and NOT going to school then yep,they pay rent. Now am I going to put that rent in a special savings account to give to them when they move out? probably, but they don't need to know that.

If he's not helping out and working then why is he getting a free ride? I'd look at the cost of a one bedroom apartment and go from there in figuring out how much.

In the OP scenario, I would definitely start charging rent. I’m just not sure of the amount.
When I was young and living at home, my mom charged me $300 a month and saved it for me. When I got married, she gave it all back. I’m not saying you need to do that, but I was slightly irresponsible and it was definitely a good/unexpected surprise.

My husband and I have had this discussion about our college aged daughter. We charge her nothing now, but if she lives at our house after she finishes college we will give her a couple of bills to take care - internet & our heating bill. It all averages out to be pretty cheap compared to renting her own place. She’d be 22 at that time. If she were in her mid to upper 20s, we’d probably have her pay more. 

I did when they were earning at a full time job even if it was just a ‘marking my spot’ job. We saved most of it and gave it back to them when they left home but occasionally I used some of it for necessities and mostly I feel it did teach them a little of the reality of the cost of living.

We don't charge rent while they're in college. It's possible our youngest will need to live with us for a while after college, though she would very much prefer to be I her own place if she can swing it. We'd be more likely to assign and expect completion of household chores rather than charging rent. She is a good kid and has always been helpful and willing to pitch in.

ETA: our oldest has launched at this point, but it’s possible at some point her mental health will preclude her working for a while.
She will always have a place here if she needs it in that case.

This pea said it better than I did. More specifically.

My mom started charging me $300 rent when I hit 18. It was a good wake up call for when I moved out at 19. Friends of ours started taking 1/3 of their kid’s take home pay from the minute they got their first paying jobs. They also counseled their kids to put away another 1/3 in savings and they could do what they wanted with the rest. What they didn’t tell their kids was that they were investing all that money they were collecting. When the kids each wanted to buy a house they gave it all back for the down payment and it added up to a huge chunk.

For a kid in their late teens or 20’s who’s not in school full time and who’s working full time ought to be paying something toward offsetting their living expenses even if they are helping out around the house. They would still have to cook, do dishes and laundry, take out trash and pick up after themselves if they were living out on their own so why should that be different if they’re living the nice life living with mom and dad?

cecilia I think it’s a different situation when you are helping out aging parents. My brother lived with my mom in her last 8-10 years and he helped out financially with certain things as he was able, but in the years during the recession when he wasn’t working he wasn’t able to pay for much. BUT he was there doing all of the cooking and shopping, most of the housekeeping, lawn maintenance and snow shoveling and keeping an eye on her as she declined. Assisted living/nursing home was $8k a MONTH in her last year when we finally had to move her to 24 hour care, so most of my siblings felt like he actually saved her a lot of money by living with her in those last years.

No, DS saves his money and helps around the house. If he were wasteful with money or not helping, it would be different. If we did charge him rent, we would save it and give it back to him down the road.

I dont think there is a one size fits all approach here.

My son has been working full time for a couple years. I wanted him to build a good savings and start saving for his retirement first. We just started having him contribute some money for the household. It's not very much, but it's good for him to see what it's like to have that responsibility. We encourage him to live with us for as long as he wants. I want him to have a nice nest egg before he has to pay "real" rent money.

Dd will be 21 soon. And no. We don't charge bow and won't.

When she is done with colleg, graduates and begins to work I want her to save.

It is very difficult to make ends meat as a young adult in CA. I want her to have a solid start.

Since 16 she has happily helped around the home, on her own or when asked. We did life skills over chores and she loves to help out.

I was at the hospital and she took care of the home for 2 days.

I am a firm believer in starting young with mutual aid within a family. You can just assume teens and young adults will help out.

Create the community and list.

I didn't charge my daughter rent. For one thing we didn't have a mortgage and also she was/is a very responsible person with money. By the time she moved out she put two thirds down on a house and paid it off within a few years. She also put herself through college.

She always did her fair share of helping around the house and all three of us get along really well. She bought a house a few streets away from us and we still hang out together. I couldn't ask for a better child.

However, if she had been partying and irresponsible not only would I have charged her rent she would have had to get her own place.

I think each situation is unique to the child.

ETA: After high school she also paid all of her own bills, cars, gas, insurance, tuition etc.

My DS isn’t working at present, but he gets disability benefits. I charge him around 25% of those for room and board (or digs, as we would say here.😊) I would love to be able to put that money aside and give it back to him when he moves, but unfortunately I need to use it. He lived with his dad over the summer, and I really missed that extra income. 
He also does whatever jobs I ask him to. He has severe ADHD so doesn’t usually notice when something needs done, but he will happily vacuum, empty the bins, do gardening, fill and empty the dishwasher etc. And if I’m not home, he can feed himself! (This might seem obvious, but he has an eating disorder on top of the ADHD, and food is a big issue for him.)
Oh, and he pays his own car insurance and tax, phone bill, etc. 

I’ll miss him when he eventually leaves. 😄

First, beyond garbage and dishes, dint worry about his room. Close the door and move on.

Does he have a list if things he is responsible for? If you are expecting him to notice things that need to be done at the same time as you are saying his adhd prevents him from noticing things that need to be done, you are setting him up for failure and yourself for frustration.

Sit down with him and come up with a concrete list of things that need to be done and when. If it isn't done at the agreed upon time and you end up doing it, impose a fee for that. Dont nag, dont remind. He will have a list to refer to.
Charging him rent isnt going to fix the fact that he doesnt help around the house.
