Mark Mercer, ESQ

Mark Mercer is Of Counsel in Lydecker’s Los Angeles and San Diego offices. He has over 25 years of experience representing private companies and public agencies in complex legal matters, with a practice deeply rooted in California construction law. Mark began his legal career in personal injury defense before transitioning to the representation of sureties in construction litigation, where he developed extensive experience handling multi-party construction claims and performance disputes. Mark later moved into public-sector practice, representing and advising California public agencies on construction claims, bid disputes, and environmental and regulatory compliance matters.

His current construction defect experience spans residential, commercial, and public infrastructure projects and includes claims involving alleged design defects, construction deficiencies, delays, and building performance issues. He regularly counsels owners, developers, contractors, subcontractors, and design professionals through all phases of construction defect matters, from pre-litigation risk assessment and dispute resolution to complex litigation.

In addition to construction defect litigation, Mark’s practice includes real estate, project entitlement, and insurance coverage matters, giving him a comprehensive understanding of the contractual, regulatory, and coverage issues that frequently intersect with California construction disputes. His practical, solutions-oriented approach is informed by a deep understanding of California’s construction statutes, public contracting requirements, and risk allocation frameworks.

Some of his successes include:

• Obtaining a defense verdict on a million-dollar contractor lawsuit for extra payment arising from unforeseen conditions.
• Settling a several million-dollar construction defect claim of a water treatment facility.
