Massoudi Consulting Engineers is a San Francisco-based structural engineering firm providing residential and commercial structural engineering services throughout the Bay Area. We have years of structural engineering experience in the Bay Area. Our team delivers permit-ready structural designs for new construction, home remodels and additions, seismic retrofits, soft-story retrofits, foundation engineering, and accessory dwelling units across San Francisco, San Jose, Oakland, Marin County, and San Mateo County.

Every structural engineering project is assigned a dedicated licensed engineer who remains with the project from initial consultation through permit approval - providing clients direct access to the professional responsible for their drawings.

Schedule Appointment

Massoudi Consulting Engineers provides structural engineering services for a full range of residential and commercial project types throughout the San Francisco Bay Area. Our structural engineering practice covers new single-family and multi-family home construction, residential remodels and additions of all scales, horizontal and vertical home additions, bearing wall removal and beam design, seismic retrofits for single-family homes, soft-story and seismic retrofits for multi-family residential buildings, foundation design and repair, ADU structural engineering, garage-to-ADU conversions, deck and roof deck structural design, and structural assessments for existing buildings.

San Francisco's structural engineering environment is shaped by factors specific to this region: a high seismic hazard classification, a large stock of pre-code residential buildings, hillside and constrained lot conditions, and the specific plan check requirements of San Francisco DBI. Massoudi Consulting Engineers has been practicing structural engineering in this environment since 2012, and that regional experience is directly reflected in the quality, accuracy, and approvability of every drawing set produced.
