16,681 source rows labeled Final or Issued in a retained 20,267-row workbook. These are source records, not verified active jobsites or housing units. This local review revisits the earlier study's labels and calculations before public reuse.
Historical workbook review · source completeness and original receipt date not established
First year shown in the retained workbook.
Higher recorded volume; this series does not establish its cause.
Surge holds. Second straight year above 2,500.
Peak year. $462M in declared construction value.
Annual selected-row count in the earlier study.
Partial-year capture. No full-year forecast is made.
The earlier series shows 265 selected rows in 2020 and 1,751 in 2021. A change in recorded volume does not by itself establish migration, demand or the completeness of historical reporting. Older records have had longer to change status, so selecting current Final or Issued labels also changes the annual comparison.
Final and Issued permits only. Residential, commercial, repair, solar, EV. 2026 is partial through June 25.
Residential has averaged over 83% of all real construction permits since 2021.
Final and Issued are source status labels. Their combined 16,681 rows do not establish current construction activity.
Rancho Cordova declared $462 million in construction value in 2024 alone: 7.9 times the $58.8 million declared in 2020 in the earlier study. Valuations do not establish actual spending, market value or the reasons for a change.
Reported valuation fields, not actual construction spending or verified market values.
The selected records include 4,115 rows under two Production Home (New) labels. The workbook has no explicit dwelling-unit-count column. Separate solar and EV-related labels do not establish how many homes have either installation or both.
"Production Home (New)" AP Type only (Final + Issued). Excludes custom builds and trade permits.
Historical source-label counts; no home-level linkage or installation rate is established.
The earlier analysis groups builder and subdivision strings. Those transformations have not been reproduced in this aggregate audit. The rankings below are historical study outputs, not verified market shares or a complete picture of who is building today.
2020-2026 (Final + Issued). Excludes trade contractors (HVAC, plumbing, solar).
By total permits 2020-2026 (Final + Issued). Subdivisions grouped by development name.
This map is retained from the earlier study. Its parcel matching, coordinates and district assignments have not been independently revalidated in this review. Recorded permit locations do not establish current jobsites or homes built. Do not use this map to assess site-level conditions.
Each heat point is a single permitted parcel, located by its assessor parcel number through the Sacramento County parcel layer, not an estimate. No street addresses are displayed. Color intensity reflects how many permits concentrate in an area; multi-permit parcels are capped so one busy site cannot dominate the scale. Labeled markers are named subdivisions; click one to open Google Maps satellite and verify on the ground. Final + Issued permits only (16,626 of 16,681 geocoded, 99.7%). 2026 covers January through June.
A 20,267-row workbook is retained with the Rancho Cordova public-records research materials. Original receipt correspondence and complete coverage have not been established in this review. The earlier study selected Final and Issued status labels (16,681 rows). Fields include permit number, type, status, category, work type, apply/issued/finaled dates, square footage, builder, declared valuation, APN, address, and subdivision.
The earlier study contains normalized builder and subdivision groups, annual chart series and a retained map. This review recalculates workbook aggregates separately and distinguishes source measurements from transformations that have not been independently reproduced.
