good lease: what should be included?

[Edita D.]

Hey Guys,
I reviewed the lease (created by our property management) for our tenants, and I feel like we, the landlords, are not protected enough on that lease. for example, I would want to add an addendum about "changing a battery on a smoke alarm". There's nothing mentioned in the lease!!! What other points would you recommend to mention when I add addendum?
