Badges come from public records, not from us or the business. Licence verified: an issued licence number and a city permit record name the same firm. Established: ten or more permits on record. Active this year: a permit dated in the last 12 months. A business without a badge may simply work where we hold no permit records. San Diego County permit records here run to April 2025, so nothing on this page can carry Active this year.

Also in 91764: verified permit history, trade unconfirmed

These businesses pulled permits that San Diego County recorded, but the permit records do not establish which trade they work in, so we do not file them under one. Ask what they do before you ask for a quote.
