Preempted fields

2 fields on the base district schema are rewritten when the trigger fires.

FieldOpValueNote
review_typeaddhistoric_preservation_commission_certificate_of_approvalLocalities may establish a Historic Preservation Commission with authority to issue Certificates of Approval (Maryland's analog to the Certificate of Appropriateness) for exterior alterations, new construction, relocation, and demolition within designated historic districts.
base_districts[*].demolition_delay_daysfloor_at0Locality may delay demolition; statute does not impose a uniform maximum, but Annapolis (Historic District Commission since 1952), Baltimore CHAP, and most historic Maryland jurisdictions adopt 60-180 day demolition-review windows with economic-hardship findings.

Research notes

Enabling delegation, not a direct preemption. Adopted by Annapolis (Historic District Commission), Baltimore City (CHAP — Commission for Historical and Architectural Preservation), Frederick, Cumberland, Easton, Chestertown, Havre de Grace, Westminster, Frostburg, Ellicott City (Howard County), and dozens of other jurisdictions with National Register or local historic districts. Operates in parallel with Maryland Historical Trust (MHT) state-level review (Env. §5A-301 et seq.) and federal §106 NHPA consultation. Maryland Historic Revitalization Tax Credit (Tax-Gen. §5A-303) ties to MHT-certified districts.
