2025 code cycle, effective 2026 →Calculators & planning
Make the assumptions visible.
Use your own project information. Keep a copy of the inputs and take it into the design or estimating conversation.
EV charging calculator
Estimate the electricity, charging time and usage cost for your driving routine. Compare charging power with the time your car can stay plugged in.
Energy, charging time & usage cost →
Electrical load calculator
Compare connected power, selected simultaneous loads and estimated energy use. Bring the results to your electrician when planning EV charging or home electrification.
Power + energy + handoff checklist →
Cost ranges
Combine your written quotes, scope allowances and contingency into a working budget. Every dollar comes from your inputs, so you can see what is known and what still needs pricing.
Your quotes, your assumptions →
Approval timelines
Map the path from a complete application to an issued permit and utility clearance. Build a schedule from current agency estimates instead of a generic promise.
Interactive schedule worksheet →When a project starts unexpectedly
Restoration has its own first steps.
Use the dedicated water damage checklists to organize observations, belongings, drying records and the handoff to repairs.
Know what a result means
The load tool is a planning inventory. A project budget is based on your numbers. An agency link does not establish approval.
Check the original source
Program funding, code guidance and application instructions change. Dated source links make the latest version easy to find.
Bring the context
Share your scope, equipment models, site constraints and open questions with the people preparing your project.
