O'Connor Construction, Inc. is a third-generation San Diego roofing and general building contractor in San Carlos, based at 8022 June Lake Drive in the 92119 ZIP with CSLB #1078734 covering C-39 Roofing and B — General Building classifications. Brandon O'Connor leads the company as CEO, continuing a family contracting lineage with over two decades of combined project experience. The women-owned corporation was incorporated in June 2020 with Julia D. O'Connor serving as director, secretary, and treasurer. Roof replacement is the primary trade line — full tear-off, resheathing, underlayment, and shingle or tile installation on the single-family homes that fill San Carlos's hillside streets between Lake Murray and Cowles Mountain — and attic insulation upgrades during the exposed-deck phase run in the same project window that Attic Construction uses for insulation-only scopes in College Area. Leak detection and targeted roof repair handle the interim scope for homeowners not yet ready for a full replacement, covering flashing reseal, valley repair, and damaged-shingle replacement. The B — General Building classification extends the company's authority into home additions and interior remodels, where roofing ties directly into framing, waterproofing, and structural work on room additions and patio enclosures. BuildZoom scores the firm at 93 out of 120, placing it in the top 27 percent of California contractors. June Lake Drive sits in San Carlos's residential interior near Navajo Road, where 1970s and 1980s composition-shingle roofs are cycling into their second or third replacement interval. HVAC system inspections during re-roofing — particularly when attic-mounted air handlers are exposed — coordinate with CoolFix Pro in San Carlos for duct sealing and unit evaluation. The $15,000 contractor's bond is on file with the CSLB under both the C-39 roofing specialty and the B general building authority required for projects where structural modifications extend beyond the roof plane.
