## Why do prices in Duarte differ?

In our October 2026 cost tables, Duarte sits 10% below the LA County average. The biggest local factor is San Gabriel Valley labor rates. Beyond that, the usual suspects decide the number: how much plumbing and electrical moves, the finish level, how hard the site is to work on, and how long plan check takes at City Hall.
