The MCD approach
Calm is not passive. It is organized.
Our role is to bring the owner, designer, engineer, inspector, and trades into one workable sequence, with decisions made at the right time.
01
Understand the property
We start with existing conditions, the intended outcome, and the constraints that could change the plan.
02
Define the work
We separate necessary work from optional work, identify allowances and long-lead items, and make the budget easier to understand.
03
Coordinate the sequence
We plan around permits, inspections, procurement, site logistics, and the handoffs between trades.
04
Deliver and close well
We track quality, changes, punch list, documentation, and the details that determine whether a project truly feels finished.

What does a San Francisco general contractor do?
A general contractor turns the owner’s goals and design documents into a coordinated construction plan. This includes defining the scope, aligning budget and schedule, coordinating permits and inspections, sequencing subcontractors, addressing field questions, checking quality, and organizing closeout. MCD provides this coordination for residential and light commercial projects in the San Francisco Bay Area, helping the owner, design team, and trade partners stay aligned on decisions and next steps.
Does MCD handle residential remodeling and additions?
Yes. MCD manages kitchen, bathroom, whole-property, and addition projects from scope and estimating through construction and closeout. We coordinate trades, track schedule and key decisions, address site conditions, and arrange required inspections. The work is tailored to project scope, permit requirements, and owner priorities.
Does MCD perform structural or seismic upgrades?
MCD coordinates structural and seismic construction, including foundation and framing work, repairs, temporary works, and existing-condition issues. We work from project documents with design professionals, inspectors, and field teams to resolve clarifications and sequencing. Engineering design and approvals remain with the project’s retained design professionals.
Does MCD work on ADUs and small residential development?
Yes. MCD supports ADUs, garage conversions, additions, and small infill projects. Early coordination helps clarify scope, site constraints, budget, schedule, and next design or permitting steps. During construction, MCD coordinates trades and project decisions through completion, with involvement matched to the project’s size and needs.
What areas of the Bay Area does MCD serve?
MCD is based in San Francisco and considers projects throughout the Bay Area. We review inquiries based on location, project scope, site access, permitting context, schedule, and available capacity. We confirm service coverage and fit during the initial discussion because travel and jurisdiction requirements vary.
