Sometimes when landlords have posted regarding tenants having insects in their units, someone facetiously posts that it is a violation of "no pets" to have those critters.So, I was watching a show on TLC this week, and an episode included what is in the link below.

You are under no obligation to fix anything else, but you may want to send over a handyman to look at the windows (a little WD-40 may do the trick), replace the light bulbs, the garage door and the bathroom window (could be a health and safety item). 

SF do not cash flow well ever and can be a target of both professional tenants and tenants with pets.

Those can be the best kind because someone else paid for the exiting build out, training employees and weeding through the duds, stabilizing and creating a history of sales over time you can track,etc.Those businesses have already created multi-generational customers from the grandfather,father,and son to eat there.Great business opportunity is generally where the owner is wanting to retire, has to relocate, health problems, partnership split, divorce causes division of assets, bankruptcy sale, etc.You want the business to throw off great cash flow on it's own and be established but get the discount because of external operator issues.

You may also want to consider charging pet rent and charging rent for a washer/dryer to generate more income per month.

I currently work as a substance use & mental health counselor in Los Angeles. 

What I learned- always get a hefty security deposit to start with and charge additional deposits for pets.

It is a natural reaction, and a pet peeve of many attorneys.

His next step is to call the building inspector or health department and have you cited for violations.

The only way it can exceed that one month amount is if you require a pet deposit (which also has its limits) when they bring in pets.To file a complaint its only $50 I think but after all costs are done its about $700 I believe.
