The property was sold for $1, it was a large white elephant with potential hazardous materials and possible ground contamination. 

I am curious if I am understanding the only way a tenant in Texas has a right to withhold rent is if there is an amicable agreement between tenant and landlord or if the landlord fails to remedy a problem with the house that impacts the the safety and health of the tenants.I am trying to keep things simple and not complicated on this question. :)

Most cities would likely be best off with limited restrictions (limiting enforcement time & costs) other than enforcing any already existing health and safety laws.

They wouldn’t put a fire hazard in a 5 and 6 year olds class room where we live.According to your theory your tenants shouldn’t have a stove, hair or clothes dryer, or anything that could cause damage to your units it sounds like.

i replace lockset during walkthru to start relationship with tennant with there safety in mind. i find it builds trust and shows you care about there safety

The Electrical Safety Authority has more information regarding this at www.esasafe.com. 

What is a Health Hazard Eviction?

Obviously, living without electricity may be hazardous to both the tenant and the property.To that end, I would NOT contact any mental health services.

I spoke to the Office Assistant of safety and permits in NO earlier this afternoon.

This is providing all egress and safety codes were met.
