Because property assessment for Maryland is centralized at the Maryland State Department of Assessments & Taxation (SDAT), the strongest protections are set at the state level. You might encourage the agency and our state representatives to maintain robots.txt rules that disallow automated scrapers, a Terms of Use that prohibits automated access, and a property-owner notification system that alerts residents when their records are accessed.
