San Francisco Solar Permit Plans & PE Stamped Engineering
Fast 48–72 hour CAD plan sets, PE structural & electrical stamps, PG&E interconnection, and NEM 3.0 battery storage design for SF DBI and all Bay Area building departments.
San Francisco DBI & PG&E Building Code Compliance
Permitting solar PV systems in San Francisco and the Bay Area involves navigating complex SF Fire SFFD setbacks, PG&E rule 21 interconnection specs, and historic structural building codes. We engineer 100% compliant permit packages for San Francisco, Oakland, San Jose, Berkeley, San Mateo, and Marin County.
- ✅ 48–72 Hour Turnarounds: Full CAD single-line diagrams (SLD) and electrical engineering.
- ✅ California Licensed PE Stamps: Structural calculation reports for flat roofs, tile, and ground mounts.
- ✅ PG&E Interconnection: Seamless utility coordination for fast permission to operate (PTO).
- ✅ NEM 3.0 Battery Storage: ESS backup design for Enphase IQ, Tesla Powerwall 3, and SolarEdge.

San Francisco Solar Engineering Questions
Does SF DBI require PE structural stamps for ballasted roof solar arrays?
Yes, San Francisco Department of Building Inspection (DBI) requires stamped California PE structural calculations verifying roof dead load capacity and wind uplift resistance for ballasted flat roof arrays.
How fast does PG&E approve solar & battery storage interconnections?
PG&E offers fast-track interconnection for compliant single-line diagrams. Our engineering team formats all electrical drawings to satisfy PG&E Rule 21 guidelines for rapid PTO approval.
