Final or current resolution of a PermitCase (approved/denied/issued/etc) — separated from PermitCase so chains (rebookings, withdrawn-then-resubmitted) are first-class.

7 props

Actor

2,827

An applicant/architect/contractor/representative. Public-record names only; municipal employees go through ReviewerCluster.

3 propsactor · cluster_only

Parcel

2,180

A tax parcel from pg_parcel_index (NJOGIS): block/lot, lot size, zoning district, FEMA flood zone/BFE, frontage road class. Public-record land data.

0 props

TimelineEvent

636

A discrete event in a permit/project timeline (submitted, reviewed, corrected, etc).

6 props

AHJ

556

Authority Having Jurisdiction — a municipality, county, or other approving body.

9 props

ContaminationCase

528

A regulatory contamination case, keyed by program and case id (e.g. njdep:PI-012345). Carries deed-notice / engineering-control / CEA / NPL status, which is the difference between historical contamination and contamination left in place.

0 props

Owner

135

A property owner-of-record (person/LLC/trust) from MOD-IV owner_name + deed grantees. Public-record data; display is gated downstream by the Daniel's Law layer (screenOwnerDisclosure), never at projection.

0 propsactor · none

Department

123

A reviewing department within an AHJ (zoning/building/fire/electrical/etc).

3 props

ElectricalDevice

An outlet, switch, light fixture, panel, breaker, smoke/CO detector. Carries voltage, amperage, gfci_flag, mounting_height.

0 props

Policy

A policy/ordinance/zoning rule that affects approvals.

3 props

PlumbingFixture

A toilet, lavatory, sink, tub, shower, water heater. Carries dfu, wsfu, drain_size, vent_size, supply_size.

0 props

Space

A bounded region (bathroom, kitchen, bedroom, mechanical closet, exterior deck). Carries area, ceiling_height, space_type, occupancy_classification, sleeping_area_flag.

0 props

BrownfieldSite

A named site from a municipal brownfield inventory (e.g. the Morris Canal Brownfields Inventory), tied to a historic block and lots. This is what turns 'block 2083' into 'DeMille Chemical Corporation', which is what makes a contaminant list targeted rather than generic.

0 props

Opening

A door, window, or egress opening within a Boundary. Carries width/height, swing, egress_compliant_flag, fire_rated_minutes.

0 props

SanbornSheet

One sheet of a Sanborn fire-insurance atlas volume, identified by (volume_id, sheet). Carries the IIIF image URL and the volume's year basis. Knowing WHICH sheet draws a parcel is not the same as reading WHAT it draws.

0 props

CodeSection

A normalized reference to a code section (IRC R310.2.1, NEC 210.12(A)(8), IPC 709). Edges link entities to the code that governs them.

0 props

Boundary

A wall, floor, ceiling, or roof assembly. Carries assembly, thickness, load_bearing_flag, fire_rating_minutes, exterior_flag.

0 props

HistoricBlock

A pre-renumbering municipal block (e.g. Jersey City historic block 2083). The JOIN KEY between historic fire-insurance maps, brownfield inventories and modern parcels: Sanborn plot numbers ARE the historic block numbers.

0 props

MechanicalEquipment

HVAC equipment: furnace, AC condenser, minisplit head, ERV, exhaust fan, duct/damper. Carries tons, kbtu, cfm, fuel.

0 props

Contaminant

A canonical contaminant family (chromium, mgp, coal, petroleum, solvent, metals) and the analytes that would test for it. Modelled separately from cases because the sampling plan is the actionable output.

0 props

FireDevice

Sprinkler head, fire alarm, smoke/CO detector, fire damper. Carries device_type, code_section, coverage_area.

0 props

StructuralElement

Beam, header, joist, ridge beam, column, post. Carries material, size, span, supports_above.

Populated Edge Types (26)

LOCATED_IN853,566

Entity is spatially located in another entity (AHJ, ZoningDistrict, Neighborhood, or Property).

* → AHJ|ZoningDistrict|Neighborhood|Property

AMENDMENT_OF22,548

Child PermitCase amends a parent PermitCase (e.g. permit XXX+A amends XXX).

PermitCase → PermitCase

SAME_PROPERTY_AS11,848

Two PermitCases located at the same Property (canonical ordering: from < to). Materialized by graph_projector_same_property.

PermitCase ↔ PermitCase

REVIEWED_BY5,591

A PermitCase, Project, Correction, or Decision was reviewed by a Department or ReviewerCluster.

PermitCase|Project|Correction|Decision → Department|ReviewerCluster

PREPARED_BY4,339

Actor (architect/engineer/owner/applicant) prepared this PermitCase. Source: pg_doc_actor_projects.block_lot match.

Actor → PermitCase

ISSUED_CORRECTION3,760

A Department/ReviewerCluster issued a Correction on a PermitCase.

Department|ReviewerCluster → Correction

NEAR1,205

A Parcel is within the screen radius of a ContaminationCase. Attributes carry `within_m` (the radius searched), NOT a distance: the NJDEP case layer is queried without geometry, so a per-site distance is not known and must not be invented on a provenance-carrying edge.

Parcel|Property → ContaminationCase

HAS_OUTCOME675

A PermitCase has a current/terminal Outcome.

PermitCase → Outcome

PRECEDED636

A entity preceded B in a timeline.

* → *

FOLLOWED_BY578

PermitCase A was filed before PermitCase B at the same Property. Materialized by graph_projector_followed_by; edge attributes include days_between + sequence_position.

PermitCase → PermitCase

CO_OCCURS_WITH473

Statistical co-occurrence of two entities (most often two Corrections).

* ↔ *[statistical]

CO_CITED_WITH295

Two Policy entities co-cited by at least one Decision (canonical from < to). Materialized by graph_projector_co_cited.

Policy ↔ Policy[statistical]

CITES_STATUTE198

A Decision/Policy cites a statutory basis.

Decision|Policy → Policy

OWNS130

Owner currently owns a Parcel (MOD-IV owner-of-record; deed-corroborated when the latest grantee matches).

Owner → Parcel|Property

DEPICTED_ON47

A Parcel is drawn on a SanbornSheet. Attributes carry the index range and whether the sheet's side-of-street matches the house number's parity: a '*' sheet draws ONE side, so an even house resolved to the odd-side sheet is a real map of the wrong buildings.

Parcel|Property → SanbornSheet

CONTAMINATED_WITH44

A BrownfieldSite or ContaminationCase is associated with a Contaminant family. Attributes state the BASIS, which today is inference from the site name rather than a sample result.

BrownfieldSite|ContaminationCase → Contaminant

GOVERNED_BY43

An entity is governed by a code section.

* → CodeSection

HAS_SITE39

A HistoricBlock contained a named BrownfieldSite according to a municipal inventory.

HistoricBlock → BrownfieldSite

PRIOR_OWNER_OF38

Owner previously owned a Parcel (deed-chain grantee of a non-latest sale in pg_deed_transactions).

Owner → Parcel|Property

CONTAINS22

Space contains a fixture / device / equipment.

Space → PlumbingFixture|ElectricalDevice|MechanicalEquipment|FireDevice|StructuralElement

OPENS_INTO19

Opening opens into a Space.

Opening → Space

SAME_MAILING_ADDRESS15

Two Owner entities share a normalized tax-mailing address — the shell-linking signal for community detection. Mega-hub addresses (mail drops) are excluded at projection.

Owner ↔ Owner

ADJACENT_TO8

Two Spaces share a Boundary.

Space ↔ Space

BOUNDS8

Boundary bounds a Space.

Boundary → Space

CROSSWALKS_TO4

A modern Parcel maps to its pre-renumbering HistoricBlock. Confidence carries the support tier of the address join; an unsupported pair must never look like a verified one.

EGRESS_FROM4

Opening is an egress path from a Space.
