Mizen Construction

Mizen Construction has spent more than 20 years building in the Bay Area. The firm delivers traditional construction techniques with a modern approach, focusing on quality, budget, and timeliness.

The company handles foundations and seismic retrofitting work, including concrete and structural tasks from footings to shear walls, built to engineer and architect specifications.

California requires contractors to hold a license from the Contractors State License Board (CSLB). General Building Contractors, Residential Remodeling Contractors, and General Engineering Contractors are among the classifications available depending on the scope and type of work. Before hiring, verify the contractor's license status and type through the CSLB online license lookup tool using the contractor's name or license number.

Building permits are required for most construction work in California. The California Building Standards Code mandates that no building or structure may be erected, enlarged, altered, repaired, moved, improved, removed, converted, or demolished without a separate permit obtained from the local building official. Code requirements vary by city and county, so check with your local San Francisco building department to confirm what permits your project needs.

When selecting a contractor, review their license classification to ensure it covers your project type. Ask the contractor about their licensing tier and confirm they understand the permit requirements for your specific work. Discuss how they handle inspections and code compliance as part of their process.
