It is incredibly exciting to see your new house progress to the next stage of construction, but it is still important to properly take note of your underlying home electrical and lighting plan, as it will be difficult to locate later. It is a good idea to take the time to snap some photos of each wall in your house before drywall is applied. Pay special attention to the location of wires and switches in each room.
You may also find it helpful to organize these photos into several files on your computer based on where they were taken in your home. Future electricians or tradespeople will thank you for doing this, as it will make it easier for them to complete their work without harming your original wiring.
