Our inspectors are challenged to ensure compliance with more than 1,000 pages of Code, and literally thousands of standards. That's a lot.

Folks might remember the "top 10 infractions" of 2022 (https://snbsc-planning.com/top-10-code-infractions-of-2022/). Here's when the relevant codes came into effect:
1: Improperly installed/missing Carbon Monoxide alarms: 2005
2: Columns not anchored: 1970
3: Improper window installation: 2000/2005 depending on the issue(s)
4: Emergency lighting requirements: 1975
5: Improper lintel construction (spaced, jacks not running to underside): 1970
6: Insulation for plumbing in exterior walls: 2010
7: Wood screws not permitted in structural connections: 1970
8: Incorrect beam splicing: 1975 or 1980 depending on the issue.
9: Truss-to-top plate connection (three nails/hurricane ties): 1970
