A service boundary is useful when it leads to a real building and a practical access plan. We inspect Frisco commercial roofs and nearby municipalities, confirming the address, roof access, operating hours, and decision window before setting a visit. The North Platinum Corridor includes multiple corporate and mixed-use properties; the Rail District includes historic downtown commercial buildings and ongoing reinvestment. Both are broad contexts, not a single facility target. We begin with the property itself and its leak or planning question.
