The new HOME Initiative in Austin significantly changes the rules of adding an accessory unit. By redefining the guidelines that regulate these structures, the initiative opens up innovative and flexible options for homeowners and developers alike. Architects will now have a greater ability to tailor their designs to the specific constraints of each site.
One of the most noteworthy changes is the removal of the previous Land Development Code (LDC) constraints, which often hindered the expansion of Duplex and Two-Family Uses. The simplification process eradicates various limitations, including:
- 10-Foot ADU Separations: The city will now defer to the IRC and/or IBC to set separation requirements between structures. This change improves design flexibility, allowing architects to tailor projects to the characteristics of each site.
- Duplex Structural Connection: Requirements that enforced a physical connection between duplex units have been discarded, offering more creative freedom in design.
- Maximum ADU Size: Previously imposed size restrictions on ADUs have been lifted, which means that building codes will now guide size and scale.
The project team now has the responsibility of selecting the appropriate building code (International Building Code (IBC) vs. International Residential Code (IRC)), enabling them to make decisions based on specific unit arrangements, such as three-story stacks.
