One booking 6 weeks from now really handicaps your ability to book MTR guests. 

I will be dealing with adults, not handicapped individuals.

I'm trying to get into a home in Washington state, which I can make changes to, to make it handicapped accessable for my mother.

A Protected Tenant is a tenant who has continuously resided in a rental unit for at least ten years, and is either: (i) 62 years of age or older OR (ii) disabled as defined in Title 42 United States Code Section 423 or handicapped as defined in Section 50072 of the California Health and Safety Code.

Nick,The whole project was rehabed in 2014 and updated with handicap access on the first floor, new roofs, and better parking arrangement.

Similarly anything more than 10% office and the building may be considered "specialized" or "flex" by the tenant pool, which again handicaps you when it comes time to release. regarding the lease itself, 6 year term is great from the perspective of a secured income stream but you need to consider where we are in the cycle.

, emergency lighting, handicap accessible entrance, accessible bathrooms, etc

That's not my market, but it seems like excellent news to me - regulations like that encourage responsible ownership/management without severely handicapping the industry, and in my opinion creates a safer environment in which to operate a business without fearing that super-strict regulations could swoop in at any moment.  

The office unit is currently 1700 sq ft of built out medical office space.  5 exam rooms, all with sinks and cabinets, two nursing stations, with sinks and cabinets, waiting room, administrative/check in area, large provider's office, large handicapped bathroom, handicapped ramp, plus a very large room with half bath on the second floor, that could be used as administrative space, or office space or staff break room.
