General Business License

Hawaii requires all businesses to obtain a General Excise Tax (GET) License from the Hawaii Department of Taxation before commencing business. This license covers the state's general excise tax, which is applied to most business activities at 4% (4.5% in Oahu).

Some businesses also need a county business license from Honolulu, Maui, Hawaii, or Kauai counties.

Home-Based Business Rules

Hawaii counties regulate home-based businesses through local zoning ordinances. Honolulu allows home occupations as an accessory use in residential districts with restrictions on customers, signage, and business activities that could affect neighbors. Hawaii's high cost of commercial space makes home-based businesses particularly attractive. The state's cottage food law specifically allows home-based food production and direct sales.

Frequently Asked Questions

Starting a welding business typically requires $15,000–$40,000, covering welding equipment ($3,000–$8,000), a vehicle and trailer ($3,000–$10,000), safety equipment ($500–$1,000), insurance, and working capital. A mobile welding setup serving job sites has lower overhead than a fixed shop.

Shop welding rates range from $65–$125/hour. Mobile and structural welding commands $85–$175/hour. Certified pipe welders earn $35–$50/hour as employees or $100–$200/hour as contractors. Custom fabrication is often quoted as a fixed project price with 40–60% material markup.

Certifications aren't legally required for general repair and fabrication work, but AWS D1.1 structural steel certification is required for many commercial, government, and infrastructure projects. Pipe welding certifications (6G position) can triple your earning potential in oil/gas and industrial sectors.

Mobile welding has lower overhead (no shop rent) but higher vehicle and fuel costs. Shops enable more complex fabrication but require $2,000–$8,000/month in rent. Many welders start mobile and transition to a shop as volume grows. Specializing in one niche (agricultural repair, pipeline, custom automotive) typically yields the highest returns.
