San Antonio, Texas, with its density of 2997 people per square mile, presents unique opportunities and considerations for accessory dwelling units (ADUs). When planning an ADU, the size of your property plays a significant role in what's possible. Larger lots might offer more flexibility for detached units, while smaller or more urban lots may lean towards attached or basement conversions. The process begins with understanding your property's zoning and any specific building codes that apply within San Antonio city limits.

We don't build it ourselves, but we arrange for the licensed pros to come out and give you a free estimate. Call today to get started on your San Antonio ADU project.

The materials you choose—from siding to kitchen finishes—also change the math significantly. Whether you’re building a detached unit or converting an existing garage shifts the permit requirements and structural work needed. We provide exact pricing confirmed free on the call.
