The Residential Building Permit Classification Temporary Amendment Act of 2026 aims to streamline the process for changing the classification of commercial properties to residential use in the District of Columbia. The bill introduces an application process for property owners seeking to reclassify their properties as Class 1A Property, which is designated for nontransient residential purposes. It establishes specific timelines for when properties can be taxed at the Class 1A rate based on the timing of their reclassification and requires owners to provide documentation to substantiate their classification changes. Additionally, the bill includes provisions for appeal rights if an application for reclassification is denied and outlines a clawback mechanism if the property is not utilized for residential purposes within a specified timeframe.

The bill also amends existing legal language, including changes to the definitions and classifications of property types. Notably, it modifies the language regarding the classification of properties and introduces a new subsection that details the consequences of erroneous classifications, including potential penalties and interest for improper tax assessments. Furthermore, it allows for administrative reviews of denied reclassification applications and grants the Chief Financial Officer discretion to extend compliance deadlines or waive penalties to prevent undue hardship on property owners. The act is set to take effect upon approval by the Mayor and will expire after 225 days.
