House Bill 23, introduced in Maryland on March 10, 2025, aims to address taxation issues related to mixed-use properties, specifically those that combine residential and commercial or industrial uses. The bill proposes that local governing bodies, such as the Mayor and City Council of Baltimore or county governments, have the authority to set special tax rates for these properties. Importantly, it mandates that they must also provide either a credit or an exemption for the residential portion of such properties.

Key provisions of House Bill 23 include the definition of "publicly available records," which encompasses valuation records from the Department, county records, and any other reliable information sources regarding property use. The bill outlines that the exemption or credit for the residential portion must be calculated based on either the square footage dedicated to residential use or the income generated from that use, ensuring that the residential areas are not unfairly taxed under the special rate.

The introduction of this bill has sparked discussions among lawmakers and stakeholders, particularly regarding its potential impact on local tax revenues and housing affordability. Proponents argue that the bill could incentivize the development of mixed-use properties, which are increasingly popular in urban areas, while critics express concerns about the implications for public funding and the equitable distribution of tax burdens.

The economic implications of House Bill 23 could be significant, as it may encourage more mixed-use developments, potentially leading to increased housing availability in urban centers. However, the bill's success will depend on how local governments implement the proposed tax credits and exemptions, as well as the ongoing debates surrounding property taxation and urban development.

As the legislative process unfolds, stakeholders will be closely monitoring the bill's progress and its potential effects on Maryland's housing market and local economies. The next steps will involve committee reviews and discussions, where further amendments may be proposed to address concerns raised during initial debates.
