How we chose these

Same scoring engine as the main San Francisco plumbing ranking, with an additional filter step: we look for Commercial signals in each provider's business categories, service tags, and recent review text.

When the Commercial filter would surface fewer than five providers, we fall back to showing top-rated plumbing pros generally - they are far more likely to handle commercial work than an unrated provider would be.
