You have to be very careful here if this is a residential eviction. Unless the lease or rental agreement specifically DEFINES "rent" to include utilities, you cannot include the utilities owed in the 3 day notice to pay rent or quit. So if the agreement just says the tenant owed rent plus 1/3 utilities, then the 3 day notice would be invalid if it asked for unpaid utilities.

The details of giving notice in an eviction can be very tedious, and must follow strict guidelines. As stated above, a 3-day notice to pay or quit is traditionally for overdue rent only. Depending on the unique language of the lease agreement, utilities are normally not to be included in a notice to quit or pay.

Good luck, and remember time is of the essence to act to protect your interests.
