Our Home City

Building in Keller Since the Beginning

Keller is our home base. Bruce Laing has been building here since 2001, and the Keller building department is the one we know best. We've submitted more permit applications in Keller than in any other city in our service area, which means we know exactly what their building department needs for a complete ADU or addition submittal.

Keller's approach to ADUs is more traditional than cities like Austin or Dallas. ADUs are classified as detached guest houses, not accessory dwelling units in the broader sense. That classification comes with specific rules: strict setbacks from property lines and the primary residence, size limits relative to the primary home, and in most residential zones, a restriction on using the guest house as an independent rental unit.

Those rules aren't obstacles. They're the parameters we design within. We know what Keller allows, we verify what your specific lot can support, and we tell you exactly what's feasible before any plans are drawn or deposits paid.
