In California, can the owner of a motel use the value of room and
board provided to resident manager as a credit in determining the
minimum wage paid to the resident manager. Example: The motel owner
provides an on-site
apartment for a resident manager who lives in the apartment full time.
The manager works from 7:00pm to 7:00am spending most of the time in
the apartment. Minimum wage would require wages of $81.00 ($6.75 X 12
hours). Assuming the reasonable value of the apartment is $30.00 per
day. Can the $30.00 per day serve as a credit against the wages of
$81.00?

You would find the above site beneficial. This is the IWC order which
covers motels.

section 10(C)

 Meals or lodging may not be credited against the minimum wage without
a voluntary written agreement between the employer and the employee.
When credit for meals or lodging is used to meet part of the
employer's minimum wage obligation, the amounts so credited may not be
more than the following:
Apartment-two-thirds (2/3) of the ordinary rental value, and in no
event more  $381.20 per month

Also if you are not "exempt" it would apear that you have some
overtime coming (1 1/2x your hourly rate over 8 in a day, 2x for
anything over 12 hrs in a day.

You can also call the DLSE district offices the numbers can be found at
