Key Takeaways
- Code compliance is law—violations create liability, sale obstacles, and safety hazards.
- Renovation scope determines how much current code applies to existing buildings.
- Zoning due diligence before acquisition prevents discovering fatal constraints.
- Universal design costs 80-90% less when planned vs. retrofitted.
Review of building codes, zoning, and accessibility requirements that govern renovation projects.
Key Stakeholders
Track 1 Recap
Five model code families (IRC, IBC, NEC, UPC/IPC, IECC) set minimum standards adopted by jurisdictions with amendments and lag. Renovation scope determines compliance triggers—cosmetic work is typically exempt while substantial renovation can trigger full current-code compliance. NEC requires 200A service, AFCI/GFCI in expanding locations. Zoning controls use, density, setbacks, and coverage independently from building code. ADA and FHA create accessibility requirements for commercial and multifamily projects with specific renovation triggers.

Common Mistakes to Avoid
Treating code compliance as an afterthought rather than a planning input
Consequence: Discovering code requirements during construction leads to costly redesigns, inspection failures, and schedule delays
Correction: Research applicable codes during the planning phase and incorporate requirements into the SOW and budget from the start
