Methodology

Every calculator runs the same unit-correct model against the committed cost manifest (last verified 2026-09-11, hash 3dbf8e8d0689923d).

(base_labor*wage_idx + base_mats*goodsRPP_idx + permitBase*permitIdx) * seasonal * tier * 1.10

Sources

• BEA Regional Price Parities — goods-RPP column / 100 (annual Dec, free download)
• BLS OEWS Wagner API — state/national wage per SOC group (annual May, free, email-registered key)
• Zonda Cost vs Value — base-spec calibration boundary (annual Q1, cite + link; no verbatim reproduction)

Limitations

Estimates only, never advice. Permits vary by city — ranges shown, not quotes. Material shocks lag annual BEA/BLS releases; the quarterly index and crowdsourced actuals recalibrate drift. Zonda Cost vs Value is cited as a boundary, never reproduced.
