Legal Question in Landlord & Tenant Law in California

The way to prove improper overnight guests at the unit you have written about is simply to stake out the property and see if the boyfriend spends the night. I would have the above verified by you and another person.

This is one of the most ridiculous questions that I've seen here. How can a landlord restrict tenant's freedom like that? If noise is your problem then complain about the noise. However with whom or what time the tenant associates or what guests she has over is no one's business. The restriction is not likely to be enforced by any judge. If anything, the tenant may have a case for harassment, breach of landlord's duty of covenant of quite use and enjoyment, constructive eviction and possible criminal stalking if tenant where to find out that someone is secretly monitoring her activities or monitoring her residence. She will be entitled to get a civil restraining and protective order against anyone engaged in such conduct. I would have no problem representing the tenant in a civil lawsuit against the landlord.

My advice, collect your rent and keep to yourself!
