Hardwired ethernet, a bigger electrical panel, whole-home leak detection — the upgrades that are cheap and easy during a renovation and expensive or impossible once the walls are closed

The specific reason to think about technology during a home renovation rather than after it comes down to one fact that contractors repeat consistently: once permits are pulled and walls are open, that is the only time low-voltage wiring, panel upgrades, and other infrastructure can be installed without tearing into finished surfaces again. A smart thermostat or a security camera can be added to any home at any time; the upgrades in this list specifically cannot be added cheaply or easily once the renovation is finished and the walls have gone back up.
The distinction that matters, according to contractors working through 2026 renovations, is between upgrades that are genuinely worth the cost of accessing open walls and those that are better handled as simple retrofits later, since not every smart home feature justifies the specific cost and disruption of being built into a renovation versus being added afterward as a standalone device.
