Seek another lawyer.As a landlord, you can set a NO PET policy unless the Pet Agreement is signed. 

Does your lease allow pets?

@Timothy Bever You cannot require a pet deposit from a tenant with an emotional support animal.

I have a no pet policy, and I know ESAs and service animals are different.

Consider all the things that could go wrong and see if the lease addresses them: unauthorized pets or tenants, early termination, security deposit, lease violations, late rent, eviction, lawn maintenance, parking, etc.5.

For example, I mention that every adult must pay a $30 application fee, pass my credit/criminal background, make a combined income of 3x the rent, and whether or not the property accepts pets.

Yeah, we understand, when all things are equal we would always choose the property with the nice and respectful middle aged couple with no kids, no pets, and excellent credit… but don’t let the imperfect tenant prevent you from pursuing a good deal.

This is my first rental property, I had it for a bit over a year. Today I got a call from the first floor tenant stating that there is a strong smell like dog/fish in her front porch. She moved the curtain she dad and...

I'd cover it with the mesh cover and then put some sort of fence around the pool so a child or pet doesn't walk on top of it 

They usually either travel alone or with a significant other (and a pet!)
