Residential Code Compliance Analyzer
Verify residential designs against building codes before permit submission
What You Can Do
You can cross-reference your residential designs against jurisdiction-specific building codes, zoning ordinances, and accessibility standards to catch compliance issues before permit submission. Claude identifies potential violations, documents compliance decisions, and highlights code conflicts with your design intent—transforming compliance from reactive problem-solving into proactive quality control that reduces revision requests by 40-60%.
Features
analyzes designs against IBC, IRC, local amendments, and jurisdiction-specific requirements to flag non-compliant elements
checks ADA, Fair Housing Act, and state accessibility standards for mixed-occupancy residential projects
verifies setbacks, lot coverage, height limits, parking, and use restrictions against local zoning codes
generates clear written records of design decisions and code compliance rationale for design reviews and permit defense
identifies issues with egress, fire separation, sprinkler requirements, and emergency systems based on occupancy classification
confirms all required documentation, drawings, and certifications are complete and compliant before submission
highlights contradictions between codes or client requests and compliance requirements, with mitigation options
Example Output
Example 1: Multi-Family Residential Building Analysis
Jurisdiction: San Francisco, CA | Occupancy: R-2 (4-story apartment)
VIOLATIONS FOUND:
✗ Unit egress: 2 units share single exit stair (IRC 1003.2.1 requires separate exits)
✗ Hallway width: 36" in upper floors (requires 44" for occupant load > 50)
✗ ADA compliance: Accessible unit bathroom has 48" doorway (requires 36" + 12" maneuvering)
COMPLIANCE VERIFIED:
✓ Fire-resistance ratings: 2-hour separation meets IRC Table 706.4
✓ Parking: 1.25 spaces/unit complies with SF Planning Code
✓ Natural light: 10% of floor area meets ventilation requirements
Example 2: Accessibility Issue Resolution
Finding: Master bedroom closet door swing blocks accessible route
Code Reference: ADA 2010 Standards 304.1 (clear floor space)
Options:
1. Relocate closet entry 18" eastward (minimal impact on layout)
2. Change to pocket door (3" depth reduction, maintains accessibility)
3. Widen hallway to 48" (structural implications noted)
Recommendation: Pocket door—lowest cost, no structural changes

You can systematically design test cases for any feature or system by analyzing requirements or code to extract test parameters, values, and business constraints. The skill generates a PICT model, executes pairwise testing logic to minimize test case count while maximizing coverage, and delivers a formatted test matrix with expected results—reducing manual test design effort while ensuring comprehensive scenario coverage.
