Massachusetts municipalities face a recurring pattern: the right question is obvious, the authoritative data exists across offices, and no one person has time to run the cross-cut. Parcenomics builds the analytical layer that does. Every engagement starts with the same data foundation — your assessor’s CAMA database, voter roll, commitment records — and reuses it across whatever set of questions your community faces most urgently.
Every engagement begins with a data access agreement and your assessor’s database or your clerk’s voter file — built once, used across all five products. Start with whichever question your Select Board, Finance Committee, or Council is facing this quarter.
Models every permissible configuration across all five property classes and shows what each means for residential tax burden, commercial taxpayers, and total revenue. When market values shift unevenly — as they have across Massachusetts — the rate structure needs to respond. Your Select Board or City Council votes with data, not last year’s number.
Explore Rate ClassificationIdentifies property owners who may be underpaying — or not paying — personal property and applicable excise obligations. Produces named, ready-to-act deliverables: demand packages, evidence files, and enforcement toolkits your assessor can use immediately.
Explore Compliance ReviewCompares sale prices against assessed values to calculate how the tax burden is actually distributed across property value tiers and neighborhoods. Identifies systematic patterns — modest homes carrying more than their share, high-value properties less — before they compound into abatement waves or DOR compliance problems.
Explore Equity AnalysisModels the RTE under MGL c.59 §5C at every percentage from 5% to 35% — or up to 50% in qualifying seasonal communities. In active use in ~24 municipalities including Boston, Cambridge, Nantucket, and Provincetown. Shows exactly who benefits, who bears increased burden, and how all Massachusetts personal exemptions interact with the levy structure.
Explore Exemption AnalysisAnalyzes your registered voter file and annual street listing to produce a demographic portrait of the people who actually vote in your community — age distribution, party mix, household density, and registration tenure — benchmarked against Massachusetts and U.S. adult population baselines. The lightest-weight municipal engagement, and often the right place to start. Grounds every subsequent policy question in the actual community it will affect.
Explore Voter Profile View Sample →Reconstructs fifteen-plus years of your town’s fiscal history from MA Department of Revenue Tax Rate Recapitulations, LA-13 new-growth certifications, and Equalized Valuation data. Quantifies what portion of recent tax-base growth came from new construction versus renovation-and-rebuild of existing properties, tracks tax-rate and levy trajectory in both nominal and inflation-adjusted terms, and places your municipality in peer context. Closes by naming the specific policy decisions under Massachusetts General Laws — rate structure, the Residential Tax Exemption, local option revenue mechanisms — that the data informs, without recommending how any of them should be resolved.
View Sample →Your municipality has the data. It just exists in different silos — the Assessor’s CAMA system, the Treasurer’s commitment records, the Clerk’s voter roll and street listing, the regulatory framework of MGL. Parcenomics synthesizes these data sets, verifies them against state statutes and formulas, and produces analytical options for your leaders to consider.
The analytical infrastructure we build for your first engagement — the data access agreements, the CAMA ingestion pipeline, the classifier calibrated to your municipality’s data idiosyncrasies — is durable. A second question builds on the first. A third builds on both. Marginal analytical cost falls as the data foundation deepens. Communities that start with one product often add the others over time, not because we push them, but because the infrastructure is already there.
