Space Selection and Planning
Choose the right room or area for your office
A dedicated room with a door is ideal for video calls and focus. Minimum room size is 70 sq ft (roughly 7x10 feet) for a desk, chair, and storage. A spare bedroom or large closet both work.
Check existing electrical capacity
A home office needs at least 2 dedicated outlets on a 20-amp circuit. A computer, monitor, and peripherals draw 300-500 watts combined. If the room only has one outlet, plan to add more at $150-$250 per outlet.
Assess internet connectivity in the room
Run a speed test from the intended desk location. You need 25+ Mbps download for video conferencing. If Wi-Fi is weak, run an ethernet cable ($50-$100 for professional installation) for a stable connection.
Set a renovation budget
A basic home office setup costs $1,500-$3,000 (desk, chair, lighting, paint). A full renovation with built-ins, electrical work, and soundproofing runs $5,000-$15,000. Track tax-deductible expenses if self-employed.
Electrical and Connectivity
Add outlets at desk height and floor level
Install 2-3 outlets at 27 inches from the floor (desk surface height) so cords don't hang visibly. Standard desk-height outlets cost $100-$200 each including the electrician's time.
Install dedicated circuit for computer equipment
A dedicated 20-amp circuit prevents tripped breakers when running multiple devices. Adding a new circuit from the breaker panel costs $200-$400. This also protects equipment from voltage fluctuations.
Run ethernet cable or upgrade Wi-Fi access point
Cat6 ethernet cable supports up to 10 Gbps over 180 feet. Running cable through walls costs $150-$300 per drop. A mesh Wi-Fi node in the office costs $80-$150 and delivers 200+ Mbps wirelessly.
Install overhead lighting on a separate switch
Overhead lighting should provide 300-500 lumens per 50 sq ft. A flush-mount LED fixture ($30-$60) with 4000K color temperature mimics natural daylight and reduces eye strain during long work sessions.
Walls, Flooring, and Soundproofing
Paint walls in a focus-friendly color
Soft blues and muted greens improve concentration — avoid bright reds or oranges in a workspace. Use eggshell or satin finish for easy cleaning. One gallon ($30-$50) covers a small office with 2 coats.
Add sound dampening for video calls
Acoustic panels ($15-$30 each) placed behind your desk and on the wall facing you absorb echo. 4-6 panels cover a 10x12 room. A solid-core door ($150-$300) blocks 50% more sound than a hollow-core door.
Install acoustic panels on key walls
Add door sweep or seal gaps around the door
Install or update flooring
Hard flooring works best with an office chair — carpet causes rolling resistance and wears quickly under casters. A chair mat costs $30-$50 for carpet, or choose luxury vinyl plank ($3-$7/sq ft) for the whole room.
Add a rug for warmth and noise reduction
A 5x7-foot rug under the desk area costs $60-$150. Rugs reduce footstep noise by 20-30 decibels on hard floors. Choose a low-pile rug so chair casters roll smoothly.
Desk and Ergonomic Setup
Select a desk that fits the room and your work style
A standard desk is 48-60 inches wide and 24-30 inches deep. Sit-stand desks add flexibility and cost $300-$700. Leave at least 36 inches of chair clearance behind the desk for comfortable movement.
Choose an ergonomic office chair
A good ergonomic chair costs $300-$600 and should last 8-10 years. Key features: adjustable seat height (16-21 inches), lumbar support, and armrests. Test chairs in person when possible.
Position monitor at correct height and distance
The top of your monitor should sit at or slightly below eye level. Place the screen 20-26 inches from your eyes. A monitor arm ($30-$80) frees desk space and allows precise height adjustment.
Set up keyboard and mouse at proper height
Keyboard height should allow your forearms to be parallel to the floor with elbows at 90 degrees. A keyboard tray ($40-$80) that mounts under the desk achieves this for most people.
Add a task light for desk work
A desk lamp with adjustable color temperature (3000K-5000K) reduces eye strain. Position it on the opposite side of your dominant hand to avoid shadows. LED desk lamps cost $30-$70.
Storage and Organization
Install shelving for books and supplies
Floating shelves ($15-$40 each) hold 30-50 pounds when anchored to studs. Install them 12-15 inches apart vertically. A wall of 4 shelves provides 16-20 linear feet of storage for under $100.
Set up a filing system for documents
A 2-drawer file cabinet holds 50-80 hanging folders. Letter-size cabinets are 15 inches wide, legal-size 18 inches. Place the cabinet within arm's reach of your chair for easy access.
Organize cables and power strips
A cable management tray ($15-$25) mounts under the desk and hides all cables. Velcro cable ties ($5 for a pack of 50) bundle cords neatly. Label each cable with masking tape so you know what's what.
Create a clean video call background
Position your desk so a bookshelf or clean wall is behind you — not a window, which causes backlighting. A ring light ($20-$40) aimed at your face produces professional-looking video quality.
Frequently Asked Questions
How much does a home office renovation cost?
A basic home office setup (desk, chair, shelving, paint) costs $1,500-$4,000. A full renovation with built-in cabinetry, electrical upgrades, and soundproofing runs $5,000-$15,000. Converting a spare bedroom into a dedicated office with custom built-ins averages $8,000-$12,000. The IRS allows a home office deduction of $5 per square foot (up to 300 sq ft) if you use the space exclusively for work.
How many electrical outlets does a home office need?
Plan for at least 6-8 outlets in a home office: 2-3 behind the desk for computer, monitor, and charger; 2 for a printer and desk lamp; and 2-3 on other walls for floor lamps, space heaters, or additional equipment. A dedicated 20-amp circuit for the office costs $200-$400 to install and prevents tripped breakers when running multiple devices. Add 2 USB outlets at desk height to avoid adapter clutter.
What is the best desk height for ergonomic comfort?
Standard desk height is 28-30 inches, which works for people 5'8" to 5'10". Your elbows should rest at 90 degrees with shoulders relaxed when typing. For people outside this height range, an adjustable-height desk ($300-$800) is worth the investment. The top of your monitor should be at or just below eye level, about 20-26 inches from your face. A sit-stand desk adds 10-15 minutes of standing per hour on average.
How do I soundproof a home office on a budget?
The most cost-effective approach is adding a solid-core door ($150-$300), which blocks 50% more sound than a hollow-core door. Add door sweeps and weatherstripping ($10-$20) to seal gaps. Acoustic panels ($20-$40 per 12-pack) on shared walls reduce echo and absorb mid-frequency noise. A bookshelf filled with books against a shared wall acts as a natural sound barrier. Full professional soundproofing with decoupled walls and insulation costs $2,000-$5,000.
What internet speed do I need for a home office?
For video calls and standard office work, 25-50 Mbps download speed per person is sufficient. If you upload large files or stream high-definition video content, aim for 100+ Mbps. A wired Ethernet connection delivers 3-5x more reliable speeds than Wi-Fi for your primary workstation. Running an Ethernet cable from your router costs $50-$200 for a professional install, or about $20 in materials as a DIY project using flat cable and adhesive clips.
