- What's specific to San Bernardino that affects this project?
- San Bernardino's hot-dry climate makes irrigation back-fill and lot-line drainage the leading sources of foundation moisture. CEC Climate Zone 10 (hot inland) drives the Title 24 energy envelope spec — that flows into HVAC sizing, glazing U-factor, and insulation thickness in the permit set.

- Is drainage & waterproofing in San Bernardino a good investment vs. moving?

- Labor rates in San Bernardino run 15–30% below LA/Bay coastal markets, and San Bernardino Building & Safety permit timelines and fees are typically faster and lower. The $5K – $17K band reflects that — without sacrificing the same CSLB-licensed crew, materials, or warranty.
