UNSPSC 30151701: Downspouts

UNSPSC 30151701 Downspouts is a Commodity code covering the supply and installation of downspout systems as part of residential and light-commercial building envelope work. State and local governments procure downspouts almost exclusively as line items bundled within roof repair, gutter replacement, and residential housing rehabilitation projects funded through Community Development Block Grant programs, rather than as standalone materials. Recent solicitations show downspouts specified in 50–80 linear feet quantities as part of scope packages that include gutter installation, roofing work, and incidental structural repairs on single-family homes.

The code sees activity primarily from city community development departments managing CDBG-funded home rehabilitation for qualified homeowners. The City of Jackson, Michigan Community Development Department has posted at least five solicitations since February 2026 for projects that include downspout installation, making it a standout repeat buyer under this code. Issuing bodies are city-level housing rehabilitation programs in Michigan and other Midwest states, contrasting sharply with the bridge and utility infrastructure procurements that appeared in the opportunities block but are not relevant to downspout demand. The City of Jackson has solicited competitive sealed bids for downspout work at 115 W Euclid (IFB due March 3, 2026), 225 W High Street (IFB due March 9, 2026, rebid June 24, 2026), 237 N Gorham Street (IFB due July 7, 2026), and 2014 Woodsum Street (IFB due July 8, 2026), with scopes calling for approximately 50–180 linear feet of downspout per project, typically in 5-inch K-type aluminum, dark brown finish, with hanger spacing per specification. All are CDBG-funded, require SAM.gov registration, current Michigan contractor licensing, performance and payment bonds, and eighteen-month warranties. Geographic activity concentrates in Michigan, particularly Jackson, with no significant volume in other states present in the recent opportunities block.
