Home Office Construction & Remodeling

Create Your Ideal Work-From-Home Space

Home office remodels run $10,000-$22,000 for a basic refresh with paint, flooring, and lighting, $28,000-$65,000 for a full remodel with custom built-in desks and electrical upgrades, and $100,000-$200,000 for premium office suites with structural changes, soundproofing, and high-end finishes. Most projects span 2-8 weeks of on-site work depending on scope. Detached backyard studio offices that qualify as ADUs add 4-10 weeks for plan-check and inspections.

Home office remodels run $10,000-$200,000 depending on scope and finishes. The single highest-leverage upgrades in any home office are dedicated electrical (multiple circuits, surge protection, USB-C wall chargers) and hardwired ethernet, both nearly impossible to add cleanly after finishes go on. Cable management is the most-requested feature. Soundproofing for video calls typically requires acoustic panels plus a solid-core door at minimum. Cost variance comes from room scope (closet conversion vs. spare-bedroom retrofit vs. detached studio build), built-ins (custom desk + shelving + concealed cabling can add $4,000-$15,000 depending on millwork grade), electrical and data (USB outlets, hardwired ethernet drops, dedicated circuit for monitors + printer), lighting design (indirect ambient + warm task lighting + at least one window-side desk position so the camera isn't backlit), and acoustics (rugs and soft-goods for echo control, soundproofing on shared walls if applicable). We plan circuit count, USB outlets, hardwired data drops, and HVAC zoning before designing the built-ins, not after. License #1131088, 2-year workmanship warranty.
