What do you think should happen. The house is literally falling apart and its attracting vermin plus housing dead pets. Again lets assume help has been offered and rejected. What should happen after years of opportunity to clean up are refused?
If this woman continually commits the highest-priority Class 1 violations, the city should levy fines, place a lien on the house and/or a vacate order. This is the normal procedure for all hazardous violations against city building code: structural issues, faulty wiring, hazardous materials, illegal additions etc.
Anyhow, all quality of life issues are non-criminal violations. At best, these civil violations are the basis for a criminal court summons and eventual prosecution. Due process is part of our fine legal system.
Except his woman has likely committed the lowest-priority Class 3 (misdemeanor) violation, and would be a waste of a criminal court's time. Immediately hazardous vs. misdemeanor = huge difference.
