Vacancy Sources, Ownership, and Control

01 What is being counted

(a)City-inventory vacant-land parcelsCity-Owned Land Server (COLS)403
(b)311-reported vacant-building sitesService requests — ownership not attached1,447
(c)Assessor-classed vacant-land parcelsCook County Assessor vacant-land classification1,149

Sources (a) and (b) together form the 1,850-record operational tracking list — the properties a corridor manager actively works. That list is not the complete vacant-land universe. The land universe reconciles the two land sources, (a) and (c), below.

02 How the land sources overlap

Parcels counted in both sources (City PIN matches)41

  • 41 City PIN matches — parcels present in both land sources.
  • 362 City-inventory parcels outside the Assessor’s vacant-land classification (city land is mostly tax-exempt).
  • 1,108 Assessor parcels not found in the City inventory.

03 Who controls the vacant land

City / Public = City-inventory parcels plus additional public parcels identified through assessor taxpayer records. Private and unknown counts are the reconciled taxpayer-of-record classifications over the same land universe. Raw taxpayer records alone would show City/Public 0.

03b Owner structure × geography

The same assessor vacant-land parcels, cross-tabulated by owner structure (from the taxpayer name) and geography (from the taxpayer mailing address).

Individual769580827
Trust9009
Government430043
Unresolved680068
Total1,0717801,149

Geography is the taxpayer mailing address’s state, not a claim about where an owner physically resides. Structure is inferred from public taxpayer-of-record name patterns.

04 Vacant buildings requiring verification

1,447311-reported vacant-building sitesOwnership unverified

These are service-request sites, not owner-verified holdings — they are not “privately held.” An exact land-plus-building total should not be published until these sites are parcel-matched and deduplicated against the land universe above.

Tax-sale / delinquencyNot yet availableCode-violation densityNot yet available

04b Exemption anomalies — records for review

Record anomalies warranting official review. A vacant land parcel cannot serve as a principal residence; these pairings are records discrepancies for the Assessor, Treasurer, and Clerk to adjudicate — no wrongdoing is asserted.

05 What this means for action

Public land parcels403Disposition · RFP · CCLBA coordination · land assembly
Known private land parcels1,043Owner outreach and development partnerships
Unknown land parcels65Ownership and title verification
Reported buildings1,447Parcel matching · ownership verification · active-status confirmation

Revitalization cannot depend on one acquisition strategy. It requires public-land disposition, local-owner partnerships, absentee-owner outreach, and targeted ownership verification.

Chatham carries 1,850 tracked vacant properties. 403 are City- or public-controlled and can move toward disposition without owner outreach; the remaining 1,447 carry unverified ownership (311-reported buildings) and start with parcel matching and ownership verification. 1,850 tracked site points intersect at least one boundary in the Explorer dataset (revision 2026-08-13). Use those overlaps to prioritize programs for review; they do not establish eligibility, current intake, or an award. Revitalization here is not a single deal — it is public-land disposition, local-owner partnerships, absentee-owner outreach, and records verification, run cluster by cluster.
