Permitting is widely regarded as one of construction’s most frustrating hurdles – full of ambiguity, shifting requirements, and regulatory complexity. ARS cuts through it. With deep relationships across city and state agencies and a thorough understanding of how each department works, ARS coordinates every aspect of the permitting process so your team can stay focused on what they do best.
Building codes are vast, intricate, and constantly evolving. ARS is a recognized leader in code compliance, providing clients with current, project-specific expertise. Accessibility compliance is legally required in all public buildings, but applying these standards in real-world construction – especially in historic buildings or creatively designed spaces—can be genuinely complex. ARS navigates the intersection of regulatory requirements and design intent, finding code-compliant solutions even when the path isn’t obvious. When the rules change – and they will – ARS keeps you ahead of them.
ARS knows whether you can make your San Francisco project happen and how long it will take to accomplish. Enlisting ARS at the start of your project to develop a strategy and perform the necessary due diligence will ensure the most streamlined building process possible.
