Phoenix has 295 building supply stores listed on SiteCity, which is enough that scrolling top to bottom isn't a great plan. Narrow it by ZIP instead: 85040 alone holds 32 listings, and 85027 adds another 24, so those two areas cover a big chunk of the city's supply. Every entry lists a phone number, and 276 of the 295 also list a website, so you can usually check hours or stock before driving over.

None of these listings are Sponsored right now. That label marks paid placement on SiteCity, and this category has zero active ones today, so what you're browsing sits in plain, unpromoted order rather than anything a store paid to move up. If you run one of these stores and the ZIP or phone listed doesn't match reality, you can claim the listing yourself and fix it, which matters in Phoenix given how concentrated some ZIPs are. Call two or three that look close to your project before committing, since store stock and hours vary even within the same ZIP.
