FAQ

How much does a shed office conversion typically cost?[+]

Most shed office conversions cost between $3,000 and $15,000 depending on your starting point, size, and finish level. Converting an existing shed in good condition with basic infrastructure runs $2,000–$5,000, while a ground-up custom build with executive finishes can exceed $30,000.

Do I need a permit for a shed office?[+]

It depends on your local jurisdiction. Adding electrical, plumbing, or HVAC typically requires permits. Some areas also have restrictions on using outbuildings as habitable space. Check with your local building department before starting — unpermitted work can cause issues when selling your home.

How long until a shed office pays for itself vs co-working?[+]

At $250/month for co-working and $50–$100/month to run a shed office, most conversions break even in 18–36 months. After that, you’re saving $150–$200 per month — plus you’re building equity in your property.

What hidden costs do people miss when budgeting?[+]

The most commonly overlooked costs are trenching for electrical (running power from house to shed), foundation leveling, permit fees, and exterior weatherproofing. These can add $1,500–$5,000 to your total. Our estimator includes these as a separate warning so you can budget accordingly.
