If they are asking for a "reasonable accomodation" under the ADA, then I believe they are required to pay for the change, and - if necessary - pay for its removal after they vacate. 

An ADA compliant ramp must be 1 foot in length for every 1 INCH of elevation change. 

Anything involving a service animal and ADA should be directly consulting an attorney on the matter as every case is different. 

Ada county job growth is 1.7% according to our regional commissioner.

Hey @Kambhampati Aswin I followed a similar path as you, first a DA and now originating mortgages and investing in real estate.

All real estate activities you engage in ad a licensee are subject to your broker supervision, and fall under the regulatory rules of your state's real estate commission or department of licensure.

Now they wont let me ad a dialer on a monthly basis because i am still signed up as an annual subscription forcing me to pay for 11 more months even if i only need it for a month or two.   

Seek to get an understanding of what they know about ADA compliant (probably nothing), present your case in calm friendly manner.  

It’s likely the GC will subcontract the concrete work to a specialist while they focus on managing the permitting process and ensuring everything is done to code—especially if there are ADA requirements involved for the ramp.Let me know if you need help navigating the process or any tips for working with contractors.

You've got ADA, FHA, and the Oregon Department of Agriculture issues.
