Can My Apartment Complex Fine Me For My 17 Yo Being Home Alone And Not Leaving Them A Note?

So I just got this email from my apartment complex, my child is 17 and has done online schooling since COVID. We also have pets.

We got an email today that reads:

"Dear Valued Residents,

This email is to notify you of an upcoming inspection starting on May 28th. The inspections will continue on until all are done through the end of this week. If you have already been inspected, please disregard this email. Management and Maintenance will be at your unit to change your furnace filter, if needed, as well as checking your smoke detectors. Management will inspect your unit and take photos of your pets, balconies/patios, bathrooms and your kitchen. As well as your carpet and fireplace if you have one.

This is mandatory. If you do not allow them in, you will be charged a $100 lease violation. If you have pets that are left unsecured and do not state on your door whether they are friendly, you will be fined. If children are left unattended with no adult there at the time of the inspection, you will be lease violated. It is your responsibility to make sure that all utility closets are cleared out and there is a clear path for them to get to your furnace and conduct their inspection properly.

If you have any questions, please do not hesitate to reach out to our leasing office. We greatly appreciate your cooperation and patience while we do what we need to keep you safe and serviced! Once again, thank you so much and enjoy the rest of your week!"

This is the 4th email this month similar to this, they send them weekly and they complete "inspections" once every other month for arbitrary reasons. (We have 0 privacy in this complex and they claim to have the right to enter at any time but can't afford to break lease) However, this is the first time they are threatening to claim we are violating the lease for obscure reasons to add fines. Like seriously, a 100.00 fine for not leaving a NOTE? What?

There is nothing in our lease about any of this, i just read through it again. Is this legal? Im in MI if it helps (also no lawyer locally that I have found will work with landlord/tenant disputes unless you are a landlord. I have called over 100 of them)
