Not to go too far afield from the original question but this town is different from any other towns with trains because we are  our own little slice or paradise...when you throw your line in the ocean you pull out a plump tasty fish and when you scatter some seeds you grow our own special datil peppers to make a tasty hot datil sauce to brush on your tasty fish...and then throw some oysters and clams on the beach fire grill...we have oceans where you can surf and skim board and Intracoastal where you can Kayak and windsurf  and marshes where you can see pretty pink spoonbills and historic streets and buildings where you can dress like a pirate and drink rum and go argggg....when you can live here NO ONE I repeat NO ONE wants to live by the tracks...so to the original poster I say I would NOT buy anything on the railroad tracks ! 

They could very easily just call the tenants and say "Hey your neighbor is complaining, yeah the one who's got the window where your BBQ grill smoke goes in....

After this issue I contacted my other tenants .Surprise …surprise ..One tenant had a leaking kitchen faucet and a huge grill in his patio.

you can look for BBQ grills, toys in the yard, cars in the drive way etc.   

Grilled fish for breakfast?

However, now that you've expressed a safety concern to him, letting him know of the potential for liability, I think he's left himself open for a claim if anything happens now, for not addressing it.In the meantime, I think I'd install something like the grill I linked to above.  

Having steady cash flow is everything in any business.I also don't allow the following:1.No parking on grass2.No abandoned cars on property3.No water beds4.No incense burning5.No outdoor grilling within 25’ of house6.No ironing on floor or carpet7.Tenant is responsible for all floors8.No RV’s or campers on grass or driveway.9.Landlord not responsible for repair nor replacement of kitchen oven or cook topGood luck JP

Bring out a grill, some burgers n dogs etc......

You can always add an addendum to your "official" contract/lease with things like "No grilling on decks"etc. 

Do they talk about the fact they like to use their webber grill indoors?
