Electrical - wires, lighting, and audio/video
Plumbing
Structural - walls, floors, stairs, etc.
Please keep in mind that as this site is just growing, I'll organize information based on logical placement. For example, a window is on a wall so it'll be in the Structural/Wall section; or a gas valve will be on pipe, so it'll be in the Plumbing section; or installing an additional cable line has to do with wiring so it'll be in the Electrical section, etc. etc. etc. Thanks for your patience.
