We have the most sophisticated building codes in human history, backed by centuries of science. Yet, we still see buildings fail. We see “sick building syndrome,” premature rot and, as we saw in the Swiss nightclub tragedy, devastating fires. Why?

The answer lies in the “enforcement gap,” Rostow’s finance and faulty legal opinions.

The complexity crisis

As building codes have become more advanced, they have also become more complex. A modern building code book is thousands of pages long. For a small-town builder or a DIY homeowner, keeping up with these changes is a massive challenge. And that is where requirements for plans stamped by a licensed design professional and reviewed and approved by the code enforcement officer enter the process. Their jobs are to ensure that the structure is properly designed and then built to the specifications of the approved plans.

The pressure of the clock

In the construction world, time is money (aka Rostow’s financial gap). Inspections take time. Sometimes, a project moves so fast that a contractor might “close up” a wall before the inspector has had a chance to see the wiring behind it. If that is allowed to pass without that second pair of eyes, a simple human error—a nicked wire or a loose pipe—can become a ticking time bomb.

The ‘grandfather’ clause

Another gap in our safety net is the existing building. Codes generally only apply to new construction or major renovations. This means that many of the buildings we live and work in every day are grandfathered in, meeting the safety standards of 1950, not the 2020s. 

Generally, that is not problematic unless there is an unauthorised change in the use of the building.  But life safety measures do exist for precode single family dwellings. Smoke detectors and carbon monoxide detectors are required as the first level of life safety. 

The greatest failing of the codes is when unintended uses for single-family dwellings, such as short-term rentals (which are regulated as small motels and hotels by the fire codes for life safety, meaning to a much higher standard than in a single-family dwelling) are allowed.

This is Rustow’s economic forces influencing the life safety imperative of codes for local economic gain.

The building code is a powerful tool, but it is not a magic wand. It requires a culture of safety—an agreement between the architect, the builder, the inspector and the homeowner that doing it “to code” isn’t just a legal requirement, but a moral one.
