Measured tools (5)

• resolve_jurisdiction

  ALWAYS CALL THIS FIRST for any Gwinnett County address or parcel. Returns which government actually regulates the land — one of 17 cities, or unincorporated Gwinnett County (67.3% of the county) — with its code citation, a confidence band and the distance to the nearest jurisdiction boundary. A mailing address is NOT the jurisdiction: most "Duluth, GA" addresses are not in the City of Duluth.

  Parameters:

  • pin — string — Gwinnett parcel PIN, e.g. "7119 100"
  • band_m — number — Uncertainty band in metres (default 150)
  • address — string — Street address, e.g. "3175 Peachtree Industrial Blvd, Duluth GA"

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• search_cases

  Search 11,848 zoning and land-use cases (1970–2026) by applicant, use, address, case number, type, year range or zoning district. County records cover UNINCORPORATED Gwinnett only.

  Parameters:

  • zone — string — Zoning district, e.g. "R-100", "C-2", "R-TH"
  • limit — integer — 1–100, default 25
  • query — string — Free text: applicant, proposed use, address or case number
  • year_to — integer
  • case_type — string — REZ, SUP, RZC, RZR, RZM, CIC, MIH, CRZ, BRD …
  • year_from — integer
  • jurisdiction — string — Jurisdiction slug, e.g. "unincorporated-gwinnett" or "duluth"

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• get_case

  Full record for a case number, including staff recommendation, Planning Commission recommendation, decision, parcels and a deep link to the source record.

  Parameters:

  • case_number (required) — string — e.g. "REZ2025-00025"
  • jurisdiction — string — Disambiguates if the number exists in more than one jurisdiction

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• get_code_section

  Ordinance text or a dimensional-standards table by citation, with its adoption and amendment dates. Accepts "402.03", "§ 402.03", "Duluth UDC § 402.03" or "Table 2-B". Tables that have not been verified against the rendered source page say so in the response.

  Parameters:

  • jurisdiction (required) — string — Jurisdiction slug, e.g. "duluth"
  • citation (required) — string — e.g. "402.03" or "Table 2-B"

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• list_jurisdictions

  All 19 jurisdictions indexed: Gwinnett County as a container, unincorporated Gwinnett as a jurisdiction in its own right, and the 17 municipalities — with their codes and boundary sources.

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared
