Residential Architectural Design Services in San Francisco - ADUs, Remodels, Additions & New Construction

Massoudi Consulting Engineers provides residential architectural design services in San Francisco and throughout the Bay Area, developing permit-ready architectural plans for home remodels, horizontal and vertical additions, accessory dwelling units (ADUs), and new custom home construction. Architectural design is developed in-house alongside our structural and civil engineering work - ensuring that architectural and engineering drawings are fully coordinated from the first design session through permit approval.

Every architectural design project is assigned a dedicated designer and engineer who remain with the project from initial consultation through the approved permit set.

Schedule Appointment

Massoudi Consulting Engineers provides architectural design as a fully integrated component of our engineering practice - when a client needs both architectural plans and structural or civil engineering drawings, all three are developed by one coordinated team. This eliminates the conflicts between architectural and engineering drawings that frequently arise when a client is working with separate firms, and it results in a permit set that moves through San Francisco DBI and Bay Area building departments more efficiently.

Residential architectural design services include: home remodel design (kitchen reconfigurations, bathroom additions, interior layout changes), horizontal home additions and room additions, second-story and vertical home additions, attached and detached ADU architectural design, junior ADU (JADU) design, garage-to-ADU conversion design, new single-family home design, SB-9 lot split ADU design, commercial-to-residential adaptive reuse design, and deck and outdoor living space design.

All architectural plans are developed to meet the requirements of the California Building Code (CBC), California Residential Code (CRC), San Francisco Planning Code, and the applicable zoning and design standards of Bay Area jurisdictions. Architectural drawings are prepared to coordinate directly with structural and civil engineering drawings, reducing the back-and-forth between disciplines that can delay a permit application.
