Licence verified, no local permit history
CSLB #1051717 · GREEN GROUP ROOFING · Corporation
Design-build ADU contractor based in Concord. Says it serves 4 California cities.
No ADU permits are on file under this licence in the cities we cover. Most California cities do not publish the contractor's name on a building permit, so this usually reflects what a city discloses rather than what a builder has built. Ask them directly for recent addresses and permit numbers you can look up.
| City | Standing | ADU permits | Pre-approved plans |

Green Group Remodeling handles ADUs, room additions, kitchens, bathrooms, and new construction from a Concord office, with further addresses in San Francisco, San Jose, and San Rafael. Design and 3D renderings come before construction, and financing is available. The business runs a separate roofing division under the same ownership.
The company’s own description · licence shown on their advertising matches the state register
ADU Standards does not issue zoning determinations and does not endorse contractors. Licence details are from the California Contractors State License Board, checked 2026-08-15. A city that pre-approves a plan has vetted the plan, not the builder. Always confirm licence standing at cslb.ca.gov before you sign anything.
