Can a tenant break the lease for pest infestation and health risk to tenants, what is a landlord's responsibility in AZ state

I understand your concern. We had many scorpion in the last house I lived in. I am not aware of any published opinions on whether scorpions pose a health hazard. A court may or may not consider them a health hazard sufficient to break the lease. There are several useful resources regarding the Arizona Residential Landlord and Tenant Act. There is an overview of the Act at the Supreme Court of Arizona's website: http://www.supreme.state.az.us/info/brochures/landlord.htm. You can get a copy of the Arizona Residential Landlord and Tenant Act from the Secretary of State's website: http://www.azsos.gov/public_services/publications/residential_landlord_tenant_Act/. You may be able to find a guide at the Maricopa County Law Library: (520) 740-8456 or at the public library. A practical suggestion: document all your communications with your landlord by writing him a letter instead of calling. And another practical suggestion: try sprinkling diatomaceous earth. It worked for us (we had tile floors). You can get food grade diatomaceous earth at a feed store for cheap. Good luck. Legal Disclaimer. I am not your attorney.
