The doorways might quickly shut on new development of wood-framed properties. No less than that’s what many regulators are pushing to make occur. After a long time of wood-framed homes being pummeled by wildfires, windstorms, and earthquakes, there may be now rising stress on builders to put money into extra strong residential development strategies.
The adjustments are forcing builders and householders to confront an uncomfortable reality: wood-framed properties, which have historically been cheaper to construct, are not viable in high-risk areas. Consequently, consideration is quickly turning towards concrete properties that naturally meet many of those new necessities and supply a sturdy, fireproof different.

The Drawback
Whereas it could appear to be the brand new codes are a direct response to the fast-moving wildfires that ripped via Los Angeles County in January 2025, their adoption is extra of an escalation of measures which have been evolving for greater than twenty years.
Nonetheless, the LA fires do supply an ideal illustration of the potential answer: a photograph of the one home that stood just about untouched amid the charred stays of the hearth in Malibu — a concrete dwelling constructed completely with noncombustible supplies, from the roof to the muse.
WUI codes make it clear that anybody nonetheless setting up wood-framed properties are constructing a legal responsibility. The chance is so excessive that insurance coverage firms are pulling out, and regulators are tightening the principles. The one path ahead is to construct with supplies that don’t burn.
The stakes couldn’t be larger. California skilled 8,024 wildfires in 2024, burning over a million acres and destroying greater than 1,700 constructions. Even householders who weren’t immediately within the hearth’s path have been impacted as insurers canceled insurance policies throughout the state, citing rising threat and escalating rebuilding prices.
Below the brand new WUI rules, merely complying with minimal requirements will add important prices to wood-framed properties. Builders should now incorporate fire-rated roofing, ember-resistant vents, boxed eaves, tempered dual-pane home windows, and noncombustible siding: all layered onto a core construction fabricated from flamable lumber.
Wooden properties have been by no means designed to face flying embers or direct flame contact. Each improve added is sort of a patch on a weak system. With concrete, you begin with a construction that’s inherently noncombustible, so assembly WUI requirements turns into a baseline moderately than a problem.

From the Floor Up
With concrete, the constructing method goes past code compliance. For instance, some firms at the moment are engineering a brand new residential constructing methodology the place each part of the house is designed to withstand hearth, in and out.
These properties begin with tilt-up, prestressed concrete wall panels. In contrast to conventional precast methods that require cranes, the corporate’s panels are poured on-site and moved into place utilizing forklifts. This innovation permits small crews, as few as three or 4 employees, to assemble a whole dwelling rapidly and affordably.
From there, each element is chosen for its fireproof properties:
- Roofs are constructed completely of steel with sealed joints to stop ember intrusion.
- Home windows and doorways use fire-rated tempered glass and noncombustible frames.
- Eaves and vents are totally enclosed and ember resistant.
- Interiors function zero drywall or steel cabinetry, eliminating typical inside fuels.
Contained in the partitions, this course of integrates thick layers of insulation, creating an hermetic, energy-efficient envelope. This addresses considered one of concrete’s historic weaknesses, poor thermal efficiency, whereas eliminating the necessity for separate insulation or inside wall methods. The result’s a construction that stays cool in summer time, heat in winter, and inherently proof against bugs, moisture, mildew, hearth, and wind.
Every part about these concrete properties is designed for resilience. They don’t simply cease embers on the exterior. Even when a wildfire surrounds the property, there’s merely nothing inside to burn.

Price & Design
For many years, value has been the most important barrier to widespread adoption of concrete properties. Wooden-framed homes have been cheaper to construct, and crews have been already skilled to work with lumber. Nonetheless, that equation is quickly altering.
Lumber costs have soared, and the added expense of WUI-required upgrades is making wood-framed properties far much less inexpensive. Even Habitat for Humanity lately introduced a shift to concrete development for some initiatives, citing wooden’s rising prices as unsustainable.
One other widespread false impression about concrete properties is that they resemble stark bunkers or lack curb enchantment. Nonetheless, trendy design enhancements show in any other case. Tilt-up panels could be completed in just about any architectural type with a variety of exterior choices: brick, stone, stucco, and even patterned and textured concrete. This provides householders full freedom to match neighborhood kinds or private preferences.
Inside, the built-in insulation offers a clean floor for customized finishes, whereas open flooring plans and pure mild guarantee these properties really feel trendy and welcoming.

Constructing to Survive Wildfires
As wildfires develop extra damaging and insurers retreat from high-risk markets, the way forward for homebuilding is obvious: homes should be constructed to withstand hearth, not merely repaired after a catastrophe.
California’s new WUI code is only the start. Related rules are anticipated to unfold throughout wildfire-prone areas all through North America. Utah has already adopted California’s lead, implementing WUI codes there as properly.
Builders who adapt now can anticipate to remain forward of the curve, whereas these clinging to outdated wood-framed strategies will face rising prices, stricter oversight, and declining insurability.
This isn’t only a wildfire challenge. Regulators and insurers in areas of the nation susceptible to hurricanes and tornadoes are additionally pushing rules concentrating on wood-framed constructions.
Concrete properties aren’t only a technical answer; they’re a lifeline.
