What manufactured-home permits reveal about local supply
Census defines the Building Permits Survey as national, state, and local statistics on new privately owned residential construction, available monthly, year-to-date, and annually. Its Form C-404 asks local permit officials for units authorized. The measured unit is an authorization by a reporting jurisdiction in the reference period; it is not a completed home, shipment, pad, or certificate of occupancy.
Coverage matters because Census's national new-residential-construction page excludes HUD-code manufactured homes from its starts, under-construction, and completions series, while the BPS classification FAQ explains how jurisdictions report manufactured homes and related foundations or pads. Record the table, classification, jurisdiction, and inclusion rule before comparing a permit count with manufactured-home supply.
Permit activity can vary with reporting timing, seasonality, voluntary reporting, and local rules. A quiet month may reflect no authorization, a missing report, or a classification difference; a spike may be a few multi-unit projects. The data describe a period and geography, but do not provide the denominator needed to estimate occupancy or demand at one park.
