Permits and license

We found no new-home permits in Arlington County under this company’s name in the last 24 months. It may build under another company name. Fairfax and Montgomery County publish permits without builder names, so ask the builder for the addresses of recent homes and look them up yourself.

Check the license yourself: Virginia DPOR license lookup (a new house needs a Class A contractor) · Montgomery County new home builders · Maryland home builder registration. Search the exact company name and check the license is active and not disciplined.
