New Homeowner Safety Checklist

Detectors, extinguishers, exits and shut-offs — the safety items worth confirming in the first weeks in a home you have just bought.

A home inspection is a snapshot of one day. This checklist covers the safety basics an owner should confirm personally, none of which require specialist skills.

Alarms and detectors

California requires working smoke alarms in bedrooms, outside sleeping areas and on every level, and carbon-monoxide alarms in homes with fuel-burning appliances or an attached garage. Requirements change, so confirm the current state and local rules rather than relying on what the previous owner installed. Test each unit with its button and note the replacement date.

Fire and escape

Keep a multi-purpose extinguisher within reach of the kitchen and another in the garage, and read the instructions before you need them. Check that bedroom windows open, that security bars have interior releases, and that the path to each exit stays clear of stored boxes.

Shut-offs and utilities

Locate the main water shut-off, the individual fixture stops, the electrical panel and the gas shut-off. Keep a meter key near the water meter. Do not turn gas back on yourself after shutting it off — that is a job for the utility or a qualified professional.

Exterior and entry

Rekey or change exterior locks, light the paths and side gates, and trim back planting that blocks sight lines to doors. Cameras and video doorbells are optional additions rather than substitutes for good lighting and solid hardware.

What a product cannot do

No device guarantees safety, prevents all damage, or replaces professional inspection and maintenance. Treat everything here as a layer, not a solution. Some home projects require specialized training, permits, or a licensed professional. Request a Pro Match if you need help finding a participating local service provider.
