Inspection Finish

This sequence gives you a cleaner way to confirm how a local team will handle load calculation before work begins and inspection finish before the job wraps.

Choosing 100A vs. 200A Upgrades in Rohnert Park
Compare the two paths most buyers and property owners weigh before moving forward locally.
100A (Standard/Legacy)
Usually the better fit when you want a simpler path, tighter short-term cost control, or fewer moving parts during the decision process.
200A (Modern Tech-Ready)
Usually the better fit when long-term performance, durability, or a stronger upside matters more than the lowest upfront number.
Detailed Breakdown
100A is often undersized for Rohnert Park homes with modern electronics. 200A provides the headroom for EV charging, mini-splits, and smart appliances in Downtown / Sonoma State District.
Use that tradeoff to compare how each option affects timing, long-term upkeep, and how well the work matches the property and market conditions around you.
