Does a basement office need an egress window if nobody sleeps in it?

Not by itself. The 2021 IRC says that when an existing basement is altered, only new sleeping rooms need an emergency escape opening. An office with a desk qualifies as neither. If the room will double as a guest bedroom, plan it as a bedroom from the start, egress window included.

How many outlets does the code expect in a basement office?

Enough that no point along the floor line of a wall is more than 6 feet from a receptacle, counting any wall space 2 feet wide or more. In practice that's an outlet within 12 feet of the next one. Desks, printers and chargers usually call for more than the minimum, so plan them first.

Basement Home Office Types

The room's main job decides the layout: closing a door on noise, borrowing a corner of a family room, or sharing the room with an occasional guest.

Closed Basement Office

A closed office has four walls and a door, which keeps video calls quiet and the work out of sight. It needs its own circuits and lighting, and HVAC supply and return so a closed door doesn't leave it stuffy.

Cost: within HomeAdvisor's $500-3,000 for a basement office
Outlets: the 6 ft spacing rule along every wall
Light: recessed cans at $125-300 each in HomeGuide's figures
Quiet: insulation in the walls and ceiling helps on calls (basement soundproofing)

Basement Office Nook

A nook is a desk built into an alcove, under the stairs or along a family-room wall. There's no door, so it's cheap, but noise from the rest of the basement reaches it.

Cost: no new walls, so less framing and drywall than a closed office
Build: a built-in desk and shelves, with an outlet strip at desk height
Wiring: a data run to the desk while the walls are open

Basement Office and Guest Room

A flex room works as an office most days and a guest room some nights. Under the 2021 IRC, a room created in an existing basement for sleeping needs its own emergency escape opening. Planning that window during the build is cheaper than adding it afterward.

Egress: required once the room is used for sleeping (egress window sizes)
Furniture: a wall bed or sofa bed keeps the floor clear for the desk

Basement Home Office Power, Light and Air

People spend more hours in an office than in most basement rooms, so the comfort details matter more.

Circuits and data
Put a dedicated circuit on the list if you run several monitors, a printer or a space heater; HomeGuide prices one at $250-900. Have data cable pulled to each desk while the walls are open, under the same electrical sub-permit.
Daylight or the code's alternative
The 2021 IRC asks habitable rooms for glazing equal to 8% of the floor area and openable area of 4%. Where that isn't possible, mechanical ventilation and lighting that averages 6 footcandles at 30 inches above the floor can stand in. Ask SoCoBD how it treats a windowless office.
Head room
A home office is living space, so it falls under the habitable-room ceiling rule (basement ceiling heights).
Radon
Pueblo County is EPA Radon Zone 1, and an office is a room people sit in all day. Test before the room is finished (radon testing and mitigation).

Tell us the room size, what equipment you run and whether the space is already finished, and we pass it to the builder. Ask for the electrical and data work listed separately from the room finish.
