It is covered under ADA. 

I'm aware of ADA guidelines, and don't have a problem with service animals.I have a problem when people outright lie to me and I have a tendency to make things a little personal so I want to make sure I'm being fair since in the past I have been a little "lax" so to speak on this tenant/property in the past.Just curious what some of you would do-or if you've had a similar situation. 

"Casual drug use is not a disability under the ADA""In order for an individual's drug addiction to be considered a disability under the ADA, it would have to pose a substantial limitation on one or more major life activities.

Curious where you are looking to invest - whether it be Canyon or Ada County.  

@Bradley Bogdan had some threads with a LOT of details in the past, so using the search BP function would be recommended.also if you go for seniors as customers, please remember to be ADA compliant. or look for the non-profits in your area already doing that. you just provide them approved housing stock.and read again what @Patti wrote: you cannot discriminate, not matter how good intentions....

Start working at 16 saving $25k by 18, invest at 18% in real estate, tax liens, whatever, reinvesting the proceeds and in 48 years at 66, have $102.4M, but ad a little more in the pot over the years and can easily get there in half the time. 

From the ADA website:A service animal is any dog that is individually trained to do work or perform tasks for the benefit of an individual with a disability, including a physical, sensory, psychiatric, intellectual, or other mental disability.

@Matthew WatsonThe building official is correct about updating the codes and ADA. 

Nice idea and more ADA friendly.  :-)  Thanks!

Canyon County (Nampa and Caldwell) still have room to grow, they are becoming the exit strategy for those that are tired of the infrastructure lags of Ada county (Boise,Meridian etc).
