AI for permitting and plan review in 2026: applicant agents, city prescreening, and expert services

Applicant side or city side

PermitFlow sells to the people filing permits: home services and commercial contractors, home builders, developers and architects. GreenLite also serves builders and developers, and says it sells plan review support to building departments too.

CivCheck and CodeComply.AI both sell to cities and reach applicants through them. CivCheck describes a prescreening platform used by city reviewers and applicants. CodeComply.AI offers AI Precheck and AI Plan Review for cities, plus a design-stage product for architects.

Agents, software, or a service

PermitFlow describes five AI agents (intake, research, submission, coordination, issuance) that pull project data, research AHJ requirements, file, track comments, and handle inspections and closeout. GreenLite describes an expert-led service, with full-service permit management and private plan review, where its staff use AI to organize plans and surface compliance risks.

CodeComply.AI describes automated code checks against ICC, NFPA, ADA, FHA and local amendments, with VersionVue revision comparison and Plan Chat for reviewers. CivCheck describes guided plan review that also teaches code compliance, across zoning, building, fire, accessibility, plumbing and structural disciplines.

Claims we could not check

PermitFlow claims 2.5x faster permit approvals, 5x ROI, a 90% reduction in administrative workload, and $20B+ of construction value permitted. CodeComply.AI's headline is permits in days, not months. CivCheck says partner cities see reduced backlogs. None of these have been tested by Means & Methods Lab.

Pricing

CivCheck is the only one of the four that explains its model publicly: its FAQ says the platform is free to city partners and applicants pay a small prescreening fee on top of city fees, though the fee amount is not listed. PermitFlow and CodeComply.AI route to demos, and GreenLite offers a free permit consultation. None lists a dollar price.

What to ask before a pilot

These are our suggestions, not findings. Run a past project that already has a city correction letter and see how many of those comments the tool catches. Ask how local amendments are added and how fast. For applicant-side tools, ask what your team still does by hand and who answers AHJ comments.
