A condemned property or building is one that a municipality (city or town) has closed, seized, or placed restrictions on because it is determined to be unsafe, unsanitary, or otherwise a risk to public health and safety.

The circumstances under which municipalities may condemn properties are usually described in local or municipal ordinances.

In Washington State, the condemnation of property or buildings is governed by local or municipal ordinances, which are rules established by cities or towns. These ordinances outline the conditions under which a property may be deemed unsafe, unsanitary, or a risk to public health and safety, warranting its closure, seizure, or the imposition of restrictions. The process typically involves an inspection by municipal officials or designated inspectors who assess the property against specific safety and health standards. If a property fails to meet these standards, it may be condemned. Property owners are usually given notice of the deficiencies and may be provided an opportunity to remedy the issues before the property is officially condemned. In some cases, if the property poses an immediate danger, it may be condemned without prior notice. Condemned properties may not be occupied or used until the issues are rectified and the property is brought up to code. The specific procedures and standards for condemnation vary by municipality within Washington State, so it is important to consult local ordinances for detailed regulations.
