Buying a house means finding out what is wrong with it. Most of that is already public, it is just scattered across agencies that have never spoken to each other, in formats nobody reads for fun.

Deedective joins them at the parcel. FEMA's flood maps, the town assessor's record, twenty-four years of recorded sales, wetlands with jurisdiction over what you can build, soil that decides whether a septic system works, and modelled flight-corridor exposure near Tweed. Source dates and gaps stay visible beside the findings.

Why here first

Because I live here. I own a house in Branford, and I built this to answer my own questions about it, how far the flood zone is, what the neighbours really sold for, whether the assessment is fair after the 2024 revaluation.

Towns get added one at a time on purpose. Every layer here needed a specific source found, verified against the town's own record, and joined to real parcel boundaries. Doing that properly for a handful of towns beats doing it carelessly for a hundred.

Who this is for

A buyer about to make an offer who wants the flood zone, the septic soil, the wetland line and the flight path before the inspection, not after. A seller checking what the assessment and the neighbours' sales say. An agent or attorney who needs those facts on one page with their sources. Every town has a summary page at /towns; every address has a dossier.

Coverage is loading…. Not every layer applies everywhere, and the site says so rather than guessing: the Tweed flight corridor is shoreline-only by construction, and only some towns publish water and sewer main geometry.

Why "Greater New Haven"

Most of the towns covered here are in the South Central Connecticut Planning Region, the current federal definition of the New Haven, CT metro area, and the actual regional-government unit New Haven's own suburbs already plan around. It is a real, named, coherent place, not a boundary drawn to fit whatever data happened to load first.

Berlin, Southington and Middletown are covered too, and are honestly not part of that region, they sit in Hartford-area planning territory instead. They are here because someone who might live there asked, which is the same reason any town gets added. The map and the About page say so rather than blur the two together.

Where it goes

The groundwork for Connecticut is done: the state publishes parcels and sales for all 169 towns through one API, and 76 of them share a single assessor-portal pattern. Other towns get added as people ask for them. If you want yours, say so.

What this is not

• Not an appraisal. Assessed values are the town's official record; market estimates are derived from real sales and labelled as estimates.
• Not a flood determination. FEMA's effective FIRM panel is the authority.
• Not a substitute for an inspection, a survey, or a lawyer. It tells you what to ask about.
