State Department of Assessments and Taxation and Department of General Services - Property Appraisal Aids - Geographic Images
HB 176 requires the State Department of Assessments and Taxation (SDAT) to expand the property appraisal tools it maintains for each county by adding a statewide and local database of geographic images. Those images must include GIS visualizations and oblique aerial photographic imagery, and the bill directs the Department of General Services to procure a uniform system of tools and services needed to prepare, install, and maintain that database. The bill also requires SDAT to develop policies by June 30, 2026, to protect the identity of individuals whose images are captured in oblique aerial photography, and to report those policies to the General Assembly by July 15, 2026.
The bill changes the cost-sharing structure between the State and local governments for this new imaging database. Counties and Baltimore City would reimburse the State for 100% of annual costs up to $1 million and 50% of costs above that amount, with those costs allocated among jurisdictions based on their share of statewide real property accounts. Existing law governing reimbursement for other SDAT administrative costs remains in place, but is amended to include the new geographic image database costs in the allocation formula.
In practical terms, HB 176 would affect SDAT, the Department of General Services, and county and Baltimore City governments by creating a new statewide appraisal-support technology system and a new local reimbursement obligation. It would also affect property assessment operations by formalizing the use of aerial imagery and GIS-based tools in appraisal work. The bill amends the Tax-Property Article of the Annotated Code of Maryland and takes effect June 1, 2026.
Because there are no committee transcripts or recorded votes provided, there is no documented floor or committee debate to gauge detailed sentiment. Based on the bill text, the measure appears administrative and technical rather than ideological, with an emphasis on modernizing assessment tools and protecting privacy. Any likely concern would center on the cost burden to counties and Baltimore City, the use of aerial imagery, and the privacy safeguards for individuals captured in those images.
HB 176 amends the Tax-Property Article to require SDAT to maintain a database of statewide and local geographic images as part of county property appraisal aids, and it assigns the Department of General Services responsibility for procuring a uniform system to support that work. It also creates a new reimbursement formula requiring counties and Baltimore City to pay for the database’s annual costs, with full reimbursement up to $1 million and partial reimbursement above that threshold, allocated by real property account share. The bill further requires SDAT to adopt privacy-protection policies for oblique aerial imagery and to report those policies to the General Assembly.
No votes or committee testimony are included, so the recorded sentiment is limited. The bill’s structure suggests general support for improving assessment technology and administrative efficiency, paired with an awareness of privacy concerns. The absence of opposition in the provided materials means the main public policy tension appears to be practical rather than partisan: modernization and data quality versus cost and privacy safeguards.
The main likely point of contention is fiscal responsibility, because counties and Baltimore City must reimburse the State for the new geographic image database, including all costs up to $1 million annually and half of any amount above that. Local governments may question the expense, the allocation method, or whether the new system provides sufficient value. A second area of concern is privacy, since the bill authorizes oblique aerial photographic imagery and specifically requires SDAT to develop policies to protect the identity of individuals captured in those images. Supporters would likely emphasize improved appraisal accuracy and more efficient assessment administration, while critics would focus on cost-sharing and surveillance-related privacy issues.
