  1. Why this checklist matters before you pick up a tool
  2. Notes on permits, professionals, and project scope

Before picking up a tool, run through this checklist covering permits, safety gear, material estimates, and utility shutoffs for common repairs.

Key Takeaways

  • Check local permit requirements before starting any structural, electrical, plumbing, or gas work.
  • Identify and shut off the correct utility supply before touching pipes, wires, or gas lines.
  • Gather all materials and tools before starting so the work area stays controlled.
  • Electrical, gas, and load-bearing structural work generally require a licensed professional.
  • A written scope and material estimate help you catch surprises before they become problems.

Why this checklist matters before you pick up a tool

Most DIY repair projects that go wrong do so in the minutes before any real work begins: the wrong circuit left live, a permit skipped, a material estimate that falls short halfway through a repair. This checklist works through the preparation steps that keep a straightforward repair straightforward.

If you are new to home repair, the first-timer's map to home repair covers the foundational concepts behind the items here. For a rundown of what tools you will actually need on hand, see the essential DIY home repair toolkit guide.

Work through each group below before your project starts. Items marked must are non-negotiable; skipping them creates safety, legal, or structural risk. Items marked should are strongly recommended. Items marked nice to have reduce friction but are genuinely optional.

Permits and legal requirements

Contact your local building department to confirm whether your specific repair requires a permit before any work begins. Must
If a permit is required, apply and receive approval before starting; do not perform regulated work and apply retroactively. Must
Check whether your repair requires a licensed electrician, plumber, or gas fitter under your state or local code. Must
Review your homeowner's insurance policy to confirm DIY work does not affect coverage for the area being repaired. Should

Utility shutoffs

Identify the exact circuit breaker, water shutoff valve, or gas shutoff that controls the work area and confirm it is labeled correctly before you need it. Must
Test the shutoff: turn it off and verify the supply is actually interrupted at the work location before proceeding. Must
Post a note or use a lockout tag on the panel or valve so no one else restores power or water while you are working. Must
Locate the main shutoff for water and gas as a backup in case the zone shutoff does not fully isolate the supply. Should

Safety gear and workspace prep

Confirm you have the personal protective equipment the task requires: at minimum, safety glasses and work gloves; add a dust mask or respirator for drywall, insulation, or old paint work. Must
Clear the work area of tripping hazards and ensure adequate lighting before starting. Must
If the repair involves a ladder, inspect it for damage and confirm it is rated for your weight plus the weight of your tools. Must
Check that your work area has ventilation if you are using adhesives, solvents, or spray products indoors. Should

Materials and tools

Write out a complete materials list from your repair plan and purchase or gather everything before starting, not mid-project. Must
Buy roughly 10 percent more of cut or consumable materials (tile, caulk, lumber) than your measurement requires to account for waste and error. Should
Confirm all tools are in working order: check that drill batteries are charged, blades are sharp, and measuring tools are accurate. Should
Have a way to dispose of old materials: verify whether your municipality requires separate disposal for paint, treated lumber, or other regulated waste. Should

Project scope and documentation

Write a one-paragraph description of exactly what you plan to do, including start and end points, so you can identify if the scope changes mid-project. Should
Take dated photographs of the area before you start, particularly if the work involves anything hidden behind walls, floors, or ceilings. Should
Share your plan with another person in the household so someone knows what systems are shut off and when you expect to finish. Nice to have

Notes on permits, professionals, and project scope

Permits exist because certain repairs affect the safety of everyone in a home, not just the person doing the work. In most U.S. jurisdictions, electrical panel work, new circuit runs, gas line changes, load-bearing wall modifications, and significant plumbing tie-ins to the main supply require a permit and, in many cases, a licensed contractor. Verify requirements with your local building department before starting; rules vary by municipality and by scope of work.

When to stop and call a professional

Electrical work inside a panel, any repair involving gas lines, and modifications to load-bearing walls are not suitable DIY projects for most homeowners. Mistakes in these areas can cause fires, gas leaks, or structural failure. If your project touches any of these systems, contact a licensed contractor and verify permit requirements with your local building department before proceeding.

When a project turns out to be larger than expected, such as finding mold, knob-and-tube wiring, or a cracked floor joist behind a wall, stop work and consult a qualified professional before continuing. The guide to basement moisture repair is a practical example of how to think through that DIY-versus-pro decision for a specific problem type.

Budgeting realistically before a project starts can prevent mid-repair compromises. The annual home expense budget checklist can help you plan repair costs alongside your other household expenses.

Old homes: watch for hazardous materials

Homes built before 1980 may contain lead paint or asbestos in insulation, floor tiles, or joint compound. Disturbing these materials without proper containment and disposal procedures creates a health hazard. If your repair involves cutting, sanding, or demolishing materials in an older home, have a qualified inspector test for hazardous materials first. Do not proceed until you understand the applicable handling and disposal rules for your area.
