AI plan check in San Francisco, CA
AI-powered construction drawing review for San Francisco projects - checked against 2022 San Francisco Building Code, the dbi enforces local amendments for seismic safety, historic preservation (article 10/11), and green building requirements beyond calgreen, and the San Francisco permit process at the San Francisco Department of Building Inspection (DBI).

Why San Francisco's Building Code Matters for Your Drawing Set
San Francisco construction projects are governed by 2022 San Francisco Building Code based on 2022 CBC with local amendments, enforced by the San Francisco Department of Building Inspection (DBI). DBI enforces local amendments for seismic safety, historic preservation (Article 10/11), and green building requirements beyond CALGreen. For a drawing set to make it through plan check without correction notices, the design must reflect both the base 2022 San Francisco Building Code and the San Francisco-specific amendments - not just the model code. Local amendments matter most when they touch life-safety provisions (egress, fire-rated assemblies, accessibility) because those are the categories plan reviewers scrutinize most closely. The same drawing that would clear plan check in a city with only the base code adopted can draw a correction notice in San Francisco because of a local amendment the design team didn't catch.
How the San Francisco Department of Building Inspection (DBI) Reviews Construction Drawings
Plan check at the San Francisco Department of Building Inspection (DBI) follows a typical AHJ workflow: intake completeness check, first-pass plan reviewer assignment, discipline-specific specialist review (structural, MEP, fire/life-safety, accessibility), correction-notice cycle, and final approval. San Francisco's standard timeline of 6–16 weeks for standard plan check reflects the volume the department processes and the typical correction-cycle count. Projects that arrive at the AHJ with un-coordinated drawings, missing sheets, or unresolved cross-discipline conflicts trigger longer timelines because each correction cycle adds days to weeks. Teams that pre-screen drawings with AI plan check before submitting catch most of these issues at the design stage, typically reducing AHJ correction cycles from 3-5 down to 1-2.
Common Plan-Check Issues in San Francisco
San Francisco construction drawings carry a specific risk profile tied to the city's construction context: mandatory soft-story retrofit program completed for most buildings; liquefaction zones require geotechnical review; shadow analysis required for buildings over 40 feet near public parks; stringent historic preservation review for many neighborhoods; enhanced green building requirements beyond state calgreen. Each of these conditions creates concrete design requirements that plan reviewers check for and that AI plan check can verify automatically. A drawing set that doesn't explicitly address the applicable conditions - for example, a San Francisco project that ignores the local construction conditions above - will draw a correction notice from the San Francisco Department of Building Inspection (DBI), even if the rest of the design is sound.
San Francisco Project Types and What They Require
The dominant San Francisco project types are High-rise residential and Office-to-residential conversions, with significant volume in Seismic retrofits, Historic renovations, Lab/biotech. Each project type triggers a different code-compliance footprint: residential and multifamily projects emphasize IBC Chapter 11 / ADA accessibility, IBC Chapter 10 egress, and IECC/Title 24 energy compliance; commercial and mixed-use projects add IBC Chapter 9 fire protection and NFPA 13/72 systems; industrial and logistics projects emphasize IBC Chapter 6 occupancy classification and high-pile storage requirements. AI plan check adjusts the rule set based on the project type and occupancy classification on the drawing set.
San Francisco Plan-Check FAQs
What building code does San Francisco use?
San Francisco, CA has adopted 2022 San Francisco Building Code based on 2022 CBC with local amendments. DBI enforces local amendments for seismic safety, historic preservation (Article 10/11), and green building requirements beyond CALGreen. The Engineer of Record and Architect of Record should design to this adopted edition, including the local amendments, and the AHJ will review against the same.
How long does plan check take in San Francisco?
Standard plan-check timelines at the San Francisco Department of Building Inspection (DBI) run 6–16 weeks for standard plan check. Complex projects, projects with code variances, and projects requiring multiple discipline reviews can extend the timeline. Pre-screening drawings with AI plan check before submitting reduces the correction-cycle count and tends to shorten the overall timeline.
Who reviews construction drawings for permits in San Francisco?
The San Francisco Department of Building Inspection (DBI) is the authority having jurisdiction (AHJ) for San Francisco, CA. Plan reviewers at the AHJ check submittals for compliance with 2022 San Francisco Building Code based on 2022 CBC with local amendments and the local amendments. The licensed plan reviewer retains the final approval decision under the adopted code.
What are the most common plan-check issues in San Francisco?
San Francisco projects most often run into plan-check issues tied to the city's specific construction context: Mandatory soft-story retrofit program completed for most buildings; Liquefaction zones require geotechnical review; Shadow analysis required for buildings over 40 feet near public parks. Designs that don't explicitly address these conditions tend to draw correction notices and extend the permit timeline.
How does AI plan check work for San Francisco construction projects?
AI plan check parses every sheet in the drawing set in minutes and flags potential code-compliance and coordination issues against 2022 San Francisco Building Code based on 2022 CBC with local amendments, with citations to the specific sheet and code section. Findings are reviewed by the design team before submitting to the San Francisco Department of Building Inspection (DBI), reducing back-and-forth correction cycles with the AHJ. AI plan check is a discovery and screening tool; the licensed Engineer of Record retains design responsibility and the AHJ retains approval authority.
What types of construction projects are most common in San Francisco?
The dominant project types in San Francisco are High-rise residential, Office-to-residential conversions, Seismic retrofits, with Historic renovations and Lab/biotech also active. Each project type carries its own code-compliance considerations, and the AI plan check engine adjusts the rule set based on occupancy classification and project type.
