What it is

A studio focused on commercial spaces. You plan layouts, finishes, lighting and furniture for small businesses, coordinate with contractors and suppliers, and keep the project on budget and on schedule. You might rent a small studio or shared office to meet clients.

Your first three steps

  1. Check your state's rules on commercial interior design, then check what credentials or registration clients and local building departments expect
  2. Put together a portfolio of commercial-style projects, even small ones, and contact local business owners and commercial real estate agents
  3. Find a contractor, architect or engineer you can partner with for permits and technical drawings
Who pays

Small business owners such as cafes, boutiques, dental offices, salons and co-working spaces, plus landlords fitting out units.

How it makes money

Project design fees, often a flat fee or a percentage of the build budget, with extra billing for site visits, drawings and project management.

Skills that help
  • Space planning for how customers and staff move
  • CAD or drawing software
  • Reading plans and working with contractors
  • Project management and budgeting
Watch out for
  • Commercial work often involves building codes, fire safety and accessibility rules, so check what your state and city require and when a licensed professional must sign off
  • Some states restrict who can submit drawings for permits, so check with your state board
  • Professional liability and general liability insurance are worth checking before signing a commercial contract
  • Projects can take months, so payment schedules and deposits matter for your cash flow
  • Check lease terms and local zoning if you rent a studio
