Best Outlet Covers + Tamper-Resistant Outlets (2026) — Modern Code Picks
Tamper-resistant (TR) outlets meet modern code and self-protect from kid fingers. Plug-in outlet covers are the cheap retrofit. Both are valid baby-proofing answers.
Modern California building code (post-2008) requires tamper-resistant (TR) outlets in new construction. They have shutters that won't open with a single object — only equal pressure on both sides (like a plug). Older homes use plug-in outlet covers as a retrofit.

Our Picks
TR Outlets vs Plug-In Covers
Tamper-resistant outlets: shutters built into outlet itself. Permanent solution, no covers to lose. The 2026 standard for new construction.
Plug-in outlet covers: cap that pushes into outlet. Cheap, no install. Easy to lose, kids over 3 yr old can pull them out.
Sliding outlet covers: replacement face plate with sliding doors that auto-close after plug removed. Middle-ground retrofit.
Whole-Home TR Retrofit
Replacing all outlets in home with TR: 30-60 outlets typical. Each outlet $5-15 part + 10-15 minute install. Whole-home retrofit $179-$349 DIY or $499-$899 pro install.
The big advantage: never worry about outlet covers, sale-of-home eliminates outdated code issue.
Sliding Outlet Covers (Best Retrofit)
Replace existing face plate with sliding-door version. Plug retracts → door slides closed. Better than plug-in covers because they auto-protect after every use.
