Know the unit
The Census Building Permits Survey publishes statistics on new privately owned residential construction, including housing units authorized by building permits. A housing-unit count is not necessarily a count of permit documents: a multifamily authorization can cover many units.
Use a common period and geography
Choose the same annual or monthly series for all markets. Preserve whether figures are preliminary or final. Keep single-family and multifamily measures separate when that distinction affects your sales territory. Do not describe residential authorizations as all construction, renovations or completed buildings.
Combine signals carefully
Our market reports pair source snapshots with Census context. A high authorization count is a reason to investigate a market, not proof that a particular contractor has open jobs or that customers will buy. Differences in contractor-source coverage also affect any apparent supply-to-demand ratio.
Before publishing a ranking
Archive the source table, year, units and calculation. Explain any exclusions and revisions. Use the official Census tables for a current comparison and preserve their definitions.
Build a comparison table without mixing signals
For each market, record geography, period, source table, measure, preliminary/final status and retrieval date. Compare like periods and preserve revisions. If you use housing units authorized, label that column accordingly instead of shortening it to “projects.”
Keep the construction signal and prospect inventory in separate columns. One describes authorizations; the other describes your covered contractor records. Before choosing a territory, investigate actual project types, customer fit and your ability to serve the location rather than dividing the two into an unexplained opportunity score.
Example: a multifamily authorization changes the story
Illustrative example: a market’s housing-unit authorizations rise because of a large multifamily development. That can matter differently to an apartment-equipment supplier and a seller focused on single-family remodeling. Neither should describe the change as an equivalent increase in separate customer jobs.
Read the underlying series and break out single-family and multifamily measures where available. Use the result to form a research question, then validate it with project-specific information before committing a sales budget.
