The area where they nested needs to be cleaned out (gross), and spray clean with household ammonia to get rid of animal feces (smell that they like).

@Joe CapobiancoAlways specific animal, specific license, with photo of animal and always add to regular rent.

We just canceled a contract on a home built in 1910 for a plethora of issues including windows, roof, nesting animals in the attic, deck about to fall apart, Garage roof unable to inspect - looked terrible from outside, sagging gutters, not-obvious water intrusion, sagging ceilings, outdated electrical.Get a home inspection.

The lease said no pets allowed except if it's a trained service animal yet when we went to walk-through, They have pet dogs. 

Even stranger, when we went to dig the footers for the addition we found hundreds of animal skeletons (sacrifices)  Needless to say, I couldn't wait to get that job done and get out of there.  

To be "cured" against one's will and cured of states which we may not regard as disease is to be put on a level of those who have not yet reached the age of reason or those who never will; to be classed with infants, imbeciles, and domestic animals.”

Because they broke the lease of smoking in the unit (hard to prove) and that they have animals in the unit (is that enough)?

It had a 4.8 with like 120 reviews.I was drawn to it because I've helped the Helen Woodward Animal Center here in San Diego to market their non-profit.Then I jumped on Propstream to see if there were any properties that might be available.

When they send you a generic "the representative is deeply concerned about (topic)" email, send them another one asking why they are avoiding a direct answer to your question.The Animal Welfare Institute has an excellent post on How to Communicate Effectively with Legislators that may give readers additional ideas.Also, sorry about my 'dark alley' comment. 

While I do not allow animals, I do include a clause that if the tenant ever considers an animal, they will be reviewed on an individual basis and they would be required to have a breed specific bite liability policy.
