In a significant development, the Austin City Council has approved the adoption of the 2024 Technical Building Codes, which will come into effect on July 10, 2025. This decision aims to enhance safety, sustainability, and housing flexibility within the city through a set of local amendments designed specifically for Austin's unique environmental and housing objectives.
The codes introduce updates across ten technical standards related to building design, construction, and maintenance. These changes are in line with national best practices and incorporate considerations for climate resilience, wildfire risk, housing diversity, and energy efficiency.
One of the critical updates involves air conditioning standards, mandating that all buildings, whether new or existing, must maintain indoor temperatures not exceeding 85 degrees and at least 15 degrees cooler than exterior conditions. This standard responds to a Council resolution from August 2023, emphasizing the importance of livability and public health during high heat periods.
Another amendment focuses on housing design flexibility, specifically permitting single-stairway designs in select multi-family residential buildings up to five stories. While this design, prevalent in other urban locales, offers flexible layouts, it is subject to certain size and fire safety constraints.
To address wildfire risks, the designated Wildland-Urban Interface and Proximity Zone C have been expanded. This will impose stricter construction requirements using fire-resistant materials and maintaining defensible space around properties in zones prone to natural vegetation.
The Council also endorsed the use of hempcrete, a plant-based construction material, for residential constructions. Hempcrete provides a low-carbon alternative to traditional concrete, aligning with the City's objectives to lower greenhouse gas emissions in the building sector.
These updates also introduce new energy efficiency standards for residential and commercial properties. Additionally, electric vehicle (EV) charging infrastructure will be required in new buildings to accommodate the increasing number of EV drivers in Austin.
The changes reflect the City's commitment to aligning building standards with the community's needs and long-term sustainability goals.
