Can I require a tenant waive right to 24 hour notice (hiding dog)

[Cali Skier]

I have a tenant that we believe is hiding a dog.  They gave the visiting dog excuse.   We have a coach that operates several properties in California and they suggested that IF we allow them to stay, its month to month, and we make them sign a waiver for me to give 24 hour notice.

I am ok to do that but I am concerned that because state law requires 24 hour notice for everything but emergencies, a signed waiver would not hold in court.  

Oklahoma Landlord and Tenant Act:  "the landlord shall give the tenant at least one (1) day’s notice of his intent to enter and may enter only at reasonable times."

Dog has to go out to use the bathroom.  Hide a trail camera outside to monitor and change the lease to say no visiting pets on property.
