Housing Affordability Is a Productivity Problem, Not Just a Rate Issue

The 2026 Economic Report of the President includes a chart that should stop anyone involved in housing. From 2000 to 2023, real house prices increased 81.9% while real median income increased only 12.3%. Housing prices rose nearly seven times faster than income. That gap is the affordability crisis in one picture.

What caught my attention, though, is what the report says next. It directly connects housing affordability to construction productivity. While overall U.S. productivity doubled from 1970 to 2020, construction labor productivity fell by about 30%. The report goes further and says residential construction productivity remains close to levels seen in the 1930s.

That should bother us. We have improved nearly every major industry through manufacturing, standardization, technology, data and process control, yet housing still asks too much labor, time and coordination to produce each building. The productivity problem in housing construction is not simply that people are working too slowly. It is that the production model still depends heavily on one-off projects, fragmented handoffs and field conditions that are difficult to control.

The Cost of Fragmentation

This is why I do not believe housing affordability is only a mortgage-rate problem. Financing matters. Land matters. Regulation matters. Materials matter. Labor matters. But the way we organize production matters too. When a project is redesigned repeatedly, approvals take months, site work and building production happen sequentially, and dozens of trades must be coordinated in the field, the cost of uncertainty eventually shows up in the price of the home.

We should be asking a more uncomfortable question: why does housing still require so much variability to deliver? Offsite construction offers one path toward relieving the housing shortage because more work can be moved into repeatable factory processes while site preparation proceeds in parallel. That does not make every modular project cheaper, and it does not make every project suitable for modular. It does change the productivity equation.

The Report Points Directly at Industrialized Construction

The 2026 report makes an unusually direct recommendation. It says state and local systems should better align codes and inspections with accepted standards for modular, prefabricated, panelized and other offsite methods. It also recommends faster approvals and greater use of third-party inspections. Whether someone agrees with every policy conclusion in the report is a separate question. The productivity logic behind that recommendation deserves serious attention.

Manufacturing cannot achieve scale when every jurisdiction creates a different production rulebook. A factory needs repeatability. It needs designs, interfaces, inspections and approvals that can move through a predictable system. That is one reason modern modular construction is more than simply moving carpenters under a roof. It is an attempt to turn more of construction into a controlled production process.

The same discipline has to extend beyond the factory. How a modular project is planned and delivered matters just as much as what happens on the production line. Site readiness, financing, design decisions, transportation, permitting, utilities and field completion still have to be integrated. If those pieces remain fragmented, factory productivity alone will not solve the affordability problem.

The Real Opportunity Is a Better Housing Delivery System

I do not believe modular construction alone solves housing affordability. Neither does panelization, automation, robotics, artificial intelligence or deregulation by itself. The larger opportunity is to redesign the delivery system so we control variability, standardize the interfaces that should repeat, and preserve flexibility where it creates value.

I have called the convergence of construction and manufacturing “Constructuring” because that is ultimately the shift housing needs. We need construction knowledge, but we also need manufacturing discipline. We need builders, factories, designers, regulators, lenders and developers operating as parts of one system instead of as isolated participants protecting individual scopes.

The labor shortage makes this even more urgent. We can continue asking how to put more people into the same production model, or we can ask how to increase the output of the people we already have. Modular construction can act as a productivity force multiplier when the design, production and field systems are aligned. The objective should not be to eliminate people. It should be to stop wasting their time.

Affordability Starts Before the Mortgage

For too long, housing has treated rising costs as inevitable. They are not. Some costs are unavoidable, but inefficiency is not a law of nature. If home prices are outrunning household income, then the affordability conversation cannot stop at interest rates and financing products. We also have to examine how the product itself is created.

If we want affordability to improve meaningfully, we have to stop asking only how to finance increasingly expensive homes and start asking a harder question:

Why does it still take us so much labor, time, coordination and uncertainty to produce them?

That is the productivity conversation housing needs to have.
