UNSPSC 30151701: Downspouts

UNSPSC 30151701 Downspouts is a Commodity code that covers the supply and installation of rain drainage components, including gutter systems and downspout assemblies used in building envelope maintenance and repair. Recent state and local solicitations show downspouts being procured as part of comprehensive roof and gutter replacement projects, typically bundled with roofing system work, gutter installation, and associated site restoration. Work spans TPO roofing system installations with integrated rain gutters and downspouts at maintenance facilities, silicone roof coatings and sealing, and residential roof-and-gutter rehabilitation funded through Community Development Block Grant programs. Issuing bodies include state departments of transportation (California Department of Transportation), county and municipal governments (Orange County, Florida; City of Jackson, Michigan), airport authorities (Melbourne Airport Authority), school districts (Fontana Unified School District), and independent public agencies managing CDBG-funded housing stock.

The code sees the heaviest recent activity in California and Michigan. California Department of Transportation has posted multiple solicitations in 2026 for TPO roofing and roof sealing services set aside for small businesses and minority-owned businesses, with the Vidal Maintenance Station project (IFPQ 08A4034, due October 20, 2026) specifying 170 linear feet of rain gutters and downspout work as part of a $484,000 price-quote ceiling. The City of Jackson Community Development Department has issued a sustained stream of sealed-bid opportunities for residential roof and gutter replacement across six properties since July 2026, each requiring downspouts ranging from 50 to 80 linear feet of commercial-size materials installed alongside roof and framing repairs. Melbourne Airport Authority awarded gutter replacement work at two airport locations to MGM Contracting of Cocoa, Florida, under ITB 2026-0604 for $98,900, including removal and installation of 7-inch aluminum commercial box gutters with 69 downspouts total across both sites. Most CDBG-funded residential projects in Jackson carry federal prevailing wage, Davis-Bacon compliance, and Section 3 employment-preference requirements alongside performance bonds and 18-month warranties.
