Editorial standards
Pages are structured to answer practical homeowner questions: expected range, cost drivers, quote checklist, quote comparison table, red flags, contractor questions, FAQs, methodology, and relevant official references. Thin pages that only repeat keywords are not acceptable for this site.
Bylines and responsibility
Calculator pages identify lengyan as the public maintainer because one person is accountable for the formula assumptions, quote-comparison structure, and correction queue. 51828 Cost Research Desk is the internal review function for consistency checks across related pages.
The public maintainer profile links to GitHub as an external identity signal. The link is not presented as a contractor license or professional credential.
Programmatic pages
State pages must add local decision value, such as licensing references, climate or scheduling factors, code and permit prompts, or local quote-risk notes. Pages that only swap a location name should not be published.
Updates
Pages should be reviewed when market pricing, incentives, building code context, or reader feedback suggests the planning ranges need adjustment.
Correction handling
Corrections are reviewed against the visible calculator model, official references where relevant, related guide consistency, and the practical question a homeowner is trying to answer before requesting bids. We prefer corrections with a page URL, location, project size, date, and written quote line items when available.
