SIA Consulting

What SIA Consulting does

SIA Consulting (legal entity SIA CONULTING CORP.) is a privately held planning, design, and engineering consulting firm headquartered at 4653 Mission Street in San Francisco. The firm delivers integrated professional services for residential and commercial development projects across the Bay Area, including feasibility studies and schematic design, code consultations covering local, state, and national regulations, full architectural design, civil and structural engineering, permit consultation and expediting with city agencies, and construction administration. It also offers a specialized soft story seismic retrofit consulting practice aligned with San Francisco's mandatory retrofit program.

The firm positions itself as a single point of contact representing clients with city agencies, neighborhood groups, and other stakeholders, drawing on what it describes as 30 years of experience and thousands of completed projects. Its primary customer segments are professional real estate developers, first-time home buyers undertaking residential development, and commercial property developers — a horizontal segmentation across project types rather than industry verticals.

The business operates as a project-based professional services practice: revenue is generated through consulting fees tied to individual engagements (feasibility, design, permitting, construction administration), with no disclosed pricing tiers, subscription model, or productized offering. The firm reports no outside funding, no parent company, no disclosed partnerships, and a headcount in the 11–50 range, consistent with a founder-led boutique consultancy rather than a scaled platform. Marketing is minimal, relying on a Wix-hosted website as the primary information channel and likely on referrals from completed projects.
