When I plan circuits for a home office remodel, I start by thinking about what will actually be plugged in, not just what is there on day one. A desk with a computer, two monitors, a router, a printer, and a few chargers does not usually draw a huge amount of power, but once you add a laser printer, space heater, or small air conditioner, the load can climb fast. That is why it is smart to separate general outlets from lighting and, if possible, give the office its own dedicated circuit or two instead of tying everything into a nearby bedroom circuit.
For most home offices, I would want at least one 20-amp circuit for receptacles, and sometimes a second one if the room will have heavy use or a lot of equipment. A single 15-amp circuit can work for a very light setup, but it leaves less margin and is easier to overload. If the office is part of a larger remodel, it is often worth running a dedicated circuit just for the computer/workstation area and keeping printers or other higher-draw items on another circuit. Lighting should be on a separate circuit from the receptacles if the layout allows it, because you do not want the whole room going dark if someone trips a breaker by plugging in a heater.
I also think about outlet placement early. In a home office, people usually regret not having enough outlets more than they regret having too many. Put receptacles where the desk actually sits, not just on the wall corners. If the desk may move later, consider outlets on more than one wall. I like to plan for power, internet, and maybe a surge protector-friendly location near the desk so cords are not stretched across the room. If the room will have built-in shelving, a printer station, or a charging nook, those spots should get outlets too.
Another big issue is future use. If there is any chance the office might later become a guest room, nursery, or studio, it makes sense to add extra capacity now while the walls are open. It is much cheaper to run an extra cable during a remodel than to open finished walls later. If you are adding a space heater, mini-split, or specialty equipment, have the load calculated before deciding what size circuit is needed. Do not assume everything can live on one breaker just because it seems fine at first.
I would also make sure the installation follows current code requirements for the area, including AFCI protection where required and GFCI where applicable, especially if the office is near a bathroom, basement, or unfinished space. If you are unsure about panel space, wire size, or whether a dedicated circuit is necessary, this is the point where a licensed electrician can save you trouble. A good plan now means fewer nuisance trips, safer operation, and a room that is actually practical to work in every day.
