Bill H.443 proposes the introduction of a new tax specifically targeting residential and commercial properties that are left vacant. The intent of this legislation is to address the issue of vacant properties, which can contribute to urban blight and reduce the overall quality of life in communities.

The bill does not specify any changes to existing legal language, indicating that it may be a standalone proposal rather than an amendment to current laws. The introduction of this tax aims to encourage property owners to either occupy their properties or make them available for use, thereby potentially increasing housing availability and stimulating local economies.
