Cities across the U.S. are facing mounting permit backlogs. With AI, they can streamline workflows, strengthen compliance, and improve turnaround times without sacrificing public safety.
The Current Reality: Permitting Takes Too Long
Cities nationwide face prolonged review timelines that slow down economic growth. According to the U.S. Census Bureau and city open data portals, residential permit approvals take an average of 8-12 months in most metro areas.

This delay creates ripple effects across local economies, pushing out project starts, inflating costs, and deterring housing production. A city's permitting speed has become a leading indicator of its ability to foster growth and innovation.
The Opportunity: Smarter Review, Not Faster Paperwork
Cities don't need to work harder. They need to work smarter. AI-assisted plan review introduces a new layer of digital intelligence that helps reviewers, not replaces them.
By automating error detection, cross-referencing code citations, and checking document completeness, jurisdictions can reduce redundant manual effort and spend more time focusing on high-impact, professional review tasks.
From Manual to Predictive: A Maturity Curve for Digital Permit Review
The path to AI-assisted permitting isn't a leap. It's a natural evolution. Most cities are already digital to some extent. The next step is integrating AI validation to make plan review proactive rather than reactive.

Why Cities Are Exploring AI Now
AI tools are now being considered by progressive jurisdictions nationwide. Municipal leaders in Los Angeles, Austin, Seattle, and Portland have all launched or announced pilot programs integrating AI or rule-based pre-screening into their plan review process.
Drivers include:
- Persistent staffing shortages and increased project volume
- Rising complexity of energy and building codes
- Mandates for housing acceleration and digital modernization
How permittable Helps
permittable's AI platform is designed to make code compliance measurable, reviewable, and automatable, helping both private and public stakeholders align faster.
Key capabilities include:
- AI Plan Intelligence: Extracts structure, envelope, and MEP details from PDFs and CAD
- Automated Code Readiness Checks: Identifies missing details, outdated citations, or incomplete documentation
- Reviewer Feedback Loop: Provides jurisdiction-specific validation logic aligned with local code adoption

Let's Build the Future, Together
AI-assisted permitting isn't science fiction. It's a public service upgrade. Cities that embrace this shift will accelerate approvals, strengthen compliance oversight, and improve collaboration between departments and the public.
