At the core of what you are doing is you are creating a sustainable business model that generates income without much of your participation.

Come back when you can add "solutions".

What is the solution?

As much as wireless is touted as a great solution, wired is still preferred due to packet loss with wireless particularly with video.

Its either a gift or not a gift.Maybe there is another solution?

That is a creative solution I will have to note.

Has anyone found a solution for this?

They might have done the laundry at 9pm but didn't make it to the dryer to collect until 11:01pm and now they have no access, and if it's a uniform they need to put on the next morning for work at 7am they might call you at 11:30pm to ask you to unlock so they can get at it.Personally I would have a talk to the late hour laundry tenant and get a better understanding on why the late hours before implementing any policy, and find out from the other tenant who complained what is the objectionable noise was it the washer agitating, was it the quick pressure draining of the water, was it the dryer buzzing when done etc...to make sure there isn't a solution before implementing a policy or a lock.Sometimes when tenants don't get along there is an underlying reason and what they complained about are the petty stuff that annoyed them but not the real reason.if you limit access you might find you are just transforming one problem into another and you now have tenants that don't get along because they are trying to do laundry at the same time.

I would approach either a foundation company, or a GC with experience (he will use an excavation company and other labor to deal with the issue.I've had good luck in the past with a few solutions:1) First and foremost, make sure there is a swale about 5' out from the house to divert water around the house2) Make sure there is some sort of foundation drain system which daylights (on the downhill side of the house)3) Make sure there is some sort of capillary break system on the exterior of the house (Delta Dry, crushed 2b stone, etc; DO NOT rely on drylock or any of the cementatious based coatings)

Nice area a little west of Pittsburgh.Originally I had a manager all setup, but there have been some issues that made that "solution" impossible.I own several units North West of here in New Castle in Lawrence county, about 25 miles away.
