Inventory sensitive equipment and verify approved point-of-use protection.
V17 — specialized system
Lightning, surge and electrical protection
Distinguish service surge protection, point-of-use devices, grounding/bonding and lightning protection systems.
Checked: 2026-08-22
Homes with solar, EV charging, pumps, networking or costly electronics may need coordinated protection rather than many power bars.
Panel additions, grounding, lightning protection or bonding are specialized electrical work.
Useful tools / data
- Sensitive-equipment inventory
- Service/panel/solar diagram
- Outage/surge history
What the professional checks
- Verify grounding and bonding
- Coordinate service/subpanel/load SPDs
- Assess lightning protection system where warranted
Sources and limits
Rules vary by jurisdiction and scope. Regulated, structural and gas work remains with the required professional.

Systems to check before closing the work
V14 connects envelope, air, fire, structure, water and code instead of treating each project in isolation.
V15
Remaining system checks not to miss
V15 covers issues that can block a project, cause a loss or become expensive once concealed.
V19
Edge systems to integrate into the project
V19 covers interfaces that become important when multiple home systems interact.
V26
Often-overlooked service interfaces
V26 connects systems that cross utility, plumbing, HVAC, envelope and metering boundaries.
V29
Household safety and compliance details
V29 connects smaller risks that often fall between finishes, appliances, plumbing and local code.
V32
Post-disaster and legacy systems
V32 connects contamination, storm damage, legacy materials and recommissioning before rebuilding.
V33
Invisible constraints before work
V33 checks electrical, legal, environmental and climate constraints that can block a project before demolition starts.
