First the ADA has zero to do with residential real estate.

For service animals (as defined under the ADA), they should be trained to perform specific tasks related to a disability. 

Since these folks are "guests" of your tenants, it's possible that would fall under ADA, and it's possible you can disallow the dogs access to the property. 

CONVERSION FEESThe owner must make a Conversion Fee payment of 5% of each unit sales price to the DHCD within 30 business days of the settlement date (§ 42–3402.04 of the Code of District of Columbia).However, exemptions can be granted if the property meets at least one of these qualifications:-Was previously owned by a sole owner or registered vacant for at least 12 months-Sold to a low-income household (80% or less of median household income)-Sold to a person 62 years of age or older-Sold to a disabled person (as defined by the ADA)-Sold to a tenant who lived in the property for at least 12 months prior to the condo conversion Basically properties without tenants for the previous 12 months are exempt.

Nope Its super hard to shut down a "Sober Living Home" due to ADA and fair Housing.  

The return on cash would be a no-brainer.Problem:- The city (Oakland Zoning) wants my Phase 1 to be minimum of 5 units, which puts me over some thresholds where I need ADA in Phase 1, I'd need a unit on 1st floor, and hit with additional impact fees in phase 1.
