Timing

Send by 20:00 your local time, ready by 07:00. Taiwan is 13 hours ahead of New York and 16 ahead of Los Angeles, so a job sent at 8 pm Pacific lands on our desk at noon. Rush within four hours covers your morning if you send before about 5 am Eastern.

What we price against

• Electrical: the National Electrical Code (NFPA 70), in the edition your state has adopted (most are on 2020 or 2023), with the items it drives: AFCI and GFCI protection, tamper-resistant receptacles, surge protection on service upgrades, emergency disconnects, kitchen and laundry circuits, EV-ready provisions where local amendments require them.
• Plumbing: the International Plumbing Code or the Uniform Plumbing Code, depending on the state, plus the International Residential Code for one- and two-family work. Water heater items follow the state energy code (expansion tanks, seismic strapping in the West, pan and drain).
• Mechanical: the IMC/IRC for ducting and equipment, Manual J/S/D references when you ask for sizing support.
• Permits: city or county permit fees as published; we put the inspection visits in the labor.
