The housing crisis in California is not a mystery—it’s a math problem. Demand far exceeds supply, and the rate at which we build housing continues to lag behind what’s needed. While modular and other modern methods of construction (MMC) offer one potential solution, California’s multifamily housing market has been slow to adopt these innovations. Why?
As part of my doctoral research, I examined the core barriers to the adoption of MMC in the state. What I found was not a lack of technology or interest—but a complex mix of institutional inertia, fragmented regulations, and misaligned incentives.
1. It’s Not the Product. It’s the Process.
MMC—whether modular, panelized, or volumetric—can reduce construction time and increase cost certainty. But these benefits are often undermined by traditional processes that weren’t designed for them. Building codes, inspections, zoning policies, and procurement systems are structured around site-built models, not industrialized approaches.
2. Financing Still Favors the Familiar
Lenders and equity partners often hesitate to fund projects using MMC due to perceived risks. Many underwriters rely on historical cost and timeline data—data that doesn’t yet exist in large volume for newer construction methods. Until MMC becomes “bankable” in the eyes of the finance community, its use will remain niche.
3. Fragmented Governance Means Conflicting Rules
California’s decentralized housing governance creates inconsistent permitting and approval pathways. One city may welcome modular systems; the next may treat them as code violations. Developers are understandably reluctant to take on the added legal and logistical complexity.
So, What Can Be Done?
To move MMC forward, California needs coordinated policy shifts and practical implementation tools. Here are three steps I recommend:
- Standardize Codes for Off-Site Construction: Adopt a unified, statewide code framework for modular and prefabricated components, making it easier to navigate compliance.
- Educate Municipal Reviewers: Equip local planning and building officials with training on MMC systems, so projects aren’t delayed by misunderstandings.
- Incentivize Pilot Projects: Offer grants or tax incentives for multifamily developers to test MMC under real market conditions—and collect data that financial institutions can rely on.
Final Thoughts
The construction industry doesn’t need to be reinvented—but it does need to be retooled. At MUSSON Factory, we help clients navigate this transition with strategy, credibility, and execution power. If we want to solve California’s housing problem, embracing modern methods of construction isn’t optional—it’s essential.
