Odds are good the lot was surveyed before you built on it and may even have metal post markers still visible.

If there happen to be a "tenant" that had a very loud sound system that played heavy death metal 24 hours a day would that be breaking any laws? 

I am wondering if anyone out there has experience with older metal fire escape related concerns or issues in MD DC and VA metro. 

New metal roof, water heater, windows, HVAC, etc. all the boring big ticket expenses have been covered for us.

I used to assume that the PVC drain pipes were not susceptible to roots or other issues like the old clay metal pipes.

Filters are cheaper than replacing gunked up A/C coils sealed inside the furnace.If the resident fails to put in any filter, the coils will gunk up.If the resident just leaves the filter in forever, it gets super dirty and not much air passes, and the coils freeze up and the A/C doesn't work.

The fee would be a lot less than that too of they had just secured the main entrances and doors with plywood or something like a $200 metal security door from Homedepot...it's just common sense..not a lot of people have it these days.. 

New kitchen, bathroom, added an owner's suite to the home, new plumbing and electrical, the HVAC worked but I had to replace the coil and duct, refinished floors.

All it took is watching a video on Youtube, a trip to wonderland aka Home Depot (that place is now a little less intimidating after I spent 30 min roaming its endless aisles looking for bolts). point of this post is instead of asking someone to fix it for me I chose to do it myself regardless of how little I knew about it (had no clue how that metal rod just magically hangs to the wall hahaha). 

Furnace shutoff or shorted out coils.
