Let me start by saying: this isn’t a political rant. It’s a call for modernization. I also want to acknowledge how fortunate I am; many people don’t have this opportunity or experience, given the high cost of real estate in NYC. With that said, this blog stems from the fact that we were able to buy a home here in New York City (something we don’t take for granted). How could we do this given the immense cost? The only way we could make it happen was by purchasing a property that required significant renovation. Renovations, architecture updates, plumbing, structural filings - you name it, we’re dealing with it. And that’s where we ran headfirst into the Department of Buildings. If you’ve ever gone through this process, you know the feeling: outdated systems, painfully slow review cycles, and endless resubmissions. For us, that’s meant five separate filings and six months (and counting!) of waiting to inch forward. Our story isn't unique; it’s a systemic bottleneck. According to the city’s data from the Mayor's Management Report, the Average Number of days from filing to approval for all applications in DOB NOW (the tool used for renovation filings) increased from 8.3 days in 2020 and 11.2 days in 2021 to 20.2 days in 2024, representing an increase of over ~80%. (pg. 366). In our case, it's been more like 60 days per filing. I work in technology delivery, building modern data platforms, AI solutions, and portals for my clients, and have been doing so for 12 years. With GenAI and agentic architectures, it doesn’t have to be this way. New York City is the command center for the global economy, a city that operates at the speed of light. We are home to innovators, dealmakers, and creators who define the future. We fund this city with some of the highest taxes in the nation, expecting infrastructure that reflects our status. Yet, when it comes to the essential task of building or renovating a home, the city hands us a folded paper map in the age of GPS. We are left to navigate a labyrinth of outdated codes and static procedures with no real-time updates, no efficient rerouting around bureaucratic traffic jams, and no reliable estimate for when we might finally reach our destination. The system isn't just slow; it's fundamentally incompatible with the city it's meant to serve.What a Smarter System Looks LikeThis isn’t science fiction; other cities are already taking action to improve this experience. In Austin, Texas, plan reviewers are utilizing an AI-powered tool that reduces the time required for certain reviews from over an hour to less than 30 minutes. Los Angeles is beta-testing a similar system for residential projects. Technology to radically change this process exists today. NYC's DOB is also involved with several AI platform PoCs, but they don't appear to be in contract with any of them (hopefully something comes of the PoCs soon) Imagine a GenAI-powered planning examiner agent running on a modern cloud platform (Azure, AWS, Google - pick your flavor). At the center, a manager agent orchestrates the process, dispatching tasks to specialist worker agents, one for architectural design, one for plumbing code compliance, and so on. The system could be built using frameworks like LangChain or LangGraph to manage complex workflows. With retrieval-augmented generation, the agents would constantly be checking against the latest, most obscure sections of the NYC Building Code. They could connect directly into the DOB’s systems, reviewing submitted documents in real-time. Here’s how it would work in practice:Submit: The architect uploads plans; the portal validates the files and extracts key metadata.AI pre‑check (minutes): Document QA flags obvious gaps and generates an annotated checklist for quick fixes.AI code pass (minutes): Specialist agents (architectural, structural, plumbing/mechanical, zoning/fire) return a single, consolidated set of redlines with direct code citations and suggested remedies.Revise & resubmit (same day): The architect updates plans; a different view highlights what changed for agents and examiners.Examiner review (next business day): Dashboard summary surfaces risks and citations; examiner asks targeted clarifications; agents re‑check only changed sections and mark as ready for approval or revert to plan examiner or architect. Approval & recordkeeping: The system pre-fills likely TR1 special inspections with references; the examiner signs; and the permit is issued with a full audit trail and performance metrics.This isn’t about replacing human oversight; it’s about amplifying it. Humans still make the final, nuanced calls. But instead of burning months on avoidable back-and-forth, the city could move projects forward in weeks.Why This is a Must-Do, not a Nice-to-HaveSo why push for this? Four reasons:Better Experience for New Yorkers: We’re paying top dollar in taxes and fees. We deserve a process that’s efficient, transparent, and user-friendly.Reduced Time and Costs: Skilled professionals (architects, structural engineers, etc.) shouldn't be stuck in resubmission loops. Let the tech handle repetitive checks, freeing people to focus on complex design and safety challenges.Addressing the Housing Crisis: Renovating or building in New York is already prohibitively expensive. As a recent City Journal report put it, New York’s permitting labyrinth is a "disaster" that drives up costs and stifles the creation of new housing, something this city desperately needs.Making New York a True Tech Leader: New York's own Chief Technology Officer, Matthew Fraser, recently helped launch the "NYC AI Nexus" to secure our city's place as a global leader in applied AI. What better way to prove it than by solving a core civic problem? By embracing solutions like this, New York can establish a benchmark for intelligent urban governance.Opening the hood: A High-Level BlueprintThis isn't about a monolithic, ten-year IT project. It’s about building a simple, modular, and scalable system.Presentation Layer: A clean citizen portal for submissions and a DOB examiner dashboard that shows prioritized queues, AI annotations, and one-click approvals.Orchestration Layer: A manager agent coordinates the end-to-end workflow, using an event bus to move tasks between services so thousands of filings can progress in parallel.Specialist Agents: Small, focused services for architecture, structure, plumbing, zoning, fire safety, etc. Each agent is an expert in its domain, grappling with famously complex sections of the NYC Building Code, like calculating egress for a mixed-use high-rise or ensuring accessibility requirements are met and returns findings with citations.Knowledge & Updates: A retrieval layer (think: vector index) keeps the latest building codes, local law amendments, and precedents at the agents’ fingertips, automatically ingested and versioned.Integrations: Secure connectors link to existing DOB systems, NYC Open Data, and FDNY updates, keeping everything in sync and auditable.Infrastructure: Containerized services that auto-scale with demand, with built-in monitoring so leaders can track real SLAs like “time to first feedback.”This isn't a complaint; it's a call to action fueled by a deep love for this city. New York has always been defined by relentless ambition and grit; that energy is being stifled by processes that belong to another era. This is not about finger-pointing. It is about seizing a crucial opportunity to modernize from the ground up and build a government as innovative as the people it serves. Let’s start with the system that shapes our homes and businesses. Let's build a more innovative process where generative AI can eliminate bureaucratic bottlenecks and handle repetitive tasks, freeing our talented public servants to tackle complex problems. A system that empowers New Yorkers to get on with building their lives. By transforming this one crucial agency, we can create a powerful proof point for the future. We can show the world that New York has the will to build not only the next generation of skyscrapers, but a smarter, more responsive government for its people. That is a project worthy of our city's ambition. But this conversation is bigger than one idea, and progress requires all of us. What are your thoughts? Have you considered any new technologies we should be considering in NYC? Let me know your thoughts. P.S. A quiet Idaho stream below from a trail walk and a jaw-dropping lake view from the cabin porch - grateful to see it and live it.
