Parcel Finder is the harness behind Deepblocks. It turns city and county records and zoning ordinances into certified parcel-level data that AI can use. AIM and DEV connect independently to this data.
Before an agent can become an expert, the city must become legible. Base zoning, overlays, state programs, and national layers each sit on their own plane. They project onto the same parcel geometry and resolve into one record, so AIM and DEV read a single source of truth, not four conflicting maps.
By-right, with overlay, and with a state program are alternative paths, not a stack you add together. On the same lot you may see 84, 96, or 120 dwelling units depending on which rules apply. The harness compares those paths so you choose with intent, not a single search string.
Digitization (locate, verify, lock, build, certify) takes about one business day. QA can take another. If a customer has already requested that market, the city is live instantly. When ordinances change, we detect the change, re-underwrite what moved, and surface opportunity again. The refresh loop returns to lock without rebuilding the city from scratch.
AIM and DEV are separate products. Both connect independently to Parcel Finder and use the same parcel and zoning information. Use AIM to find properties, then analyze selected properties separately in DEV.
Harness, data layers, yields, and how cities stay current.
A harness gives an AI model the information it needs to do a specific job. Deepblocks' harness is Parcel Finder, which turns city and county records and zoning ordinances into certified parcel-level data the AI can use. The AI does not research or interpret the city on its own; it uses the information Parcel Finder provides.
From city and county records, including parcel geometry, assessor data, zoning maps, zoning ordinances, overlays, and special districts. Each value includes its source so you can verify where it came from.
Before release, each city goes through roughly 200 checks. They verify that the data is complete, the values are reasonable, the zoning rules match the cited ordinance, and no information disappeared during an update. A city goes live only after it passes; known gaps are shown with an explanation.
Parcel Finder keeps the city's original wording and citation, then adds a common label people are likely to search. For example, “One-family dwelling” can also be found by searching for “single-family homes.” The legal wording remains unchanged, but the search works across cities that use different terms.
We first check whether the county publishes the existing building area. If it does not, we check whether a building footprint and height are available and use them to estimate the area. Each value records how it was obtained, allowing you to compare what exists today with what the zoning allows.
If we cannot produce a value from published records or available measurements, we leave it blank and explain why. Missing information is never shown as zero.
A general-purpose AI is not automatically connected to certified city and parcel data, so it will typically rely on available internet sources rather than a city and property record built to calculate the value. Deepblocks gives the AI parcel-specific information from Parcel Finder, including the source behind each zoning value. This makes the answer repeatable and verifiable.
