I shouldn't have to ask my landlord's permission to celebrate my religion and put up Christmas lights provided I'm not doing any damage to the home .

Quote from @Joseph Milano: I would talk to the renter to see what they want to do.The easiest method is to get tenant's permission to apply the funds toward their next month of rent.If they prefer the money back, I would issue them a check, money order, or cashier check when they sign the new lease.

The housing authority said they gave permission to the tenant!!!

Yeah Inslee and others are way too permissive and tenant friendly.

If they submitted contact info, then I presumed it gave me permission to contact them.

@Michael Smythe As an example what happens if your PM contract with an owner explicitly includes snow removal as a service, your company does not clear the snow in the permissable time period and a tenant or anyone for that matter slips and falls?

Keep in mind you might have to walk away from your deal with your brother, and you need to get his permission. 2. you might have to go with renting tenants at full price.

There's nothing stopping anyone from doing anything except, in this case, asking permission. 

That would be some of the most permissable zoning I've ever seen!

Is it permissible to request that they cover the additional cost?
