The Dataset Viewer has separate records and monthly_summary configurations. The train split is a file-loading label; this is an observational snapshot, not a supervised-learning benchmark.

Read without losing identifiers

import pandas as pd

base = "https://huggingface.co/datasets/claritystorm/somerset-construction-permits/resolve/main/"
records = pd.read_csv(base + "permit-records.csv", dtype=str, keep_default_na=False)
summary = pd.read_csv(base + "monthly-summary.csv", dtype=str, keep_default_na=False)
print(records.shape)  # (5596, 46)
print(summary.shape)  # (464, 8)

Alternatively use load_dataset("claritystorm/somerset-construction-permits", "records") or select "monthly_summary". Source identifiers and numeric strings in records retain their original representations.

Source and reuse

NJ Department of Community Affairs construction-permit database, distributed through NJOIT Open Data Center. Its metadata declares Public Domain. Preserve provenance and the limitations when redistributing this snapshot.

The source JSON and CSV representations were compared field by field. Counts, unique source row keys, summary totals and ZIP member CRCs passed validation. See manifest.json for exact scope and hashes.

Known limitations

• These are permit and certificate records, not independent projects, open bids or confirmed construction starts.
• The source has no street addresses, owner names, contractor contacts or detailed descriptions of work.
• Only selected commercial, industrial, assembly, educational, institutional and storage use groups are included; R and U groups are excluded, including hotels and multifamily housing.
• Municipal reporting is incomplete and unaudited. The source says the most recent two months have not been reviewed.
• Permit dates begin in 2024. Monthly summaries group by the original permit month, including records now carrying certificate status; they are not counts of certificates issued that month.
• Update records are retained and flagged. Row counts and repeated permit references must not be treated as unique projects or summed construction spending.
• Source descriptions containing replacement characters are preserved. Source numeric values and text identifiers are retained without rounding or silent repairs.
• This is a dated snapshot of a rolling source database. Future updates are not included and coverage is not through October 2026.

No independent-project counts, summed construction-spending estimates, purchasing contacts or open-bid claims are included. Update rows are retained; the source row key is municipality code (comu) plus source recordid.
