Our tenant broke the lease agreement on several clauses recently by running a legal grow facility without our knowledge.  

Would you rent your downstairs unit, knowing some stranger who rents the unit above would have access to your home, in order to go to the laundry facility in the basement? 

Your post, @Steven Westlake, reminds me of others here asking about car washes and self-storage facilities. 

May they need to go to a care facility.

Actually, the more I think about it, CA landlords might want to start including a clause that says just that - the landlord is not liable for PG&E outages.I found the following from this website: https://www.stimmel-law.com/en/articles/landlord-obligations-habitable-premises-basic-california-lawThe Statute:In terms of residential leases, in order for a landlord to be allowed to place rental units on the market, the landlord must first ensure that all of the following conditions which make the building ‘fit for human occupancy’ are met: [Civil Code Secs. 1929, 1941]Effective waterproofing and weather protection of roof and exterior wallsWell-maintained plumbing and gas facilities compliant with law in effect at the time of installationWater supply compliant with applicable law that is capable of producing hot and cold running waterWell-maintained heating facilities compliant with applicable law at the time of installationWell-maintained electrical lighting compliant with applicable law at the time of installationBuilding, grounds, and appurtenances kept sanitary and free from debris and vermin at the time of rent or leaseSufficient number of receptacles for garbageWell-maintained floors, stairways, and railingsLocks conforming to code [CA Civil Code Sec. 1941.3]Dead bolt lock on each main swinging entry doorWindow security or locking devices for windows capable of being opened

Factors to assist in determining whether miniature horses can be accommodated are whether:the miniature horse is housebrokenthe miniature horse is under the owner’s controlthe facility can accommodate the miniature horse’s type, size, and weightthe miniature horse’s presence will not compromise legitimate safety requirements necessary for the safe operation of the facility

Exemptions include "Housing accommodations in which the tenant shares bathroom or kitchen facilities with the owner who maintains their principal residence at the residential real property.(5) Single-family owner-occupied residences, including a residence in which the owner-occupant rents or leases no more than two units or bedrooms, including, but not limited to, an accessory dwelling unit or a junior accessory dwelling unit."

One of the solutions to the "housing crisis" is for government to encourage businesses to locate facilities in areas where there is a lower cost of life and higher housing supplies. 

Now the junk is on our property, and we either break the law by dumping it on someone else's property, or we pay to haul it to the dump.I tried calling the campus to get them to use their own facilities to haul it off - no luck.

If that is the case, though, then I would expect a reciprocal understanding of (Our Company) cost of providing the laundry facilities.
