The basic idea
A tool library lets members borrow tools the way they might borrow books. Many households own a drill, a ladder or a sander that they use only a few times a year. By pooling tools, a group can offer a wider range than any one person could afford or store, and members avoid buying equipment for a single job.
Tool libraries differ a great deal. Some are tiny, run from a garage or a shelf in a community hall. Others have a dedicated space, paid staff and thousands of items. The best approach for you depends on your community, your budget and how many volunteers you can rely on. The notes below are general, and rules about insurance, charging and liability differ by place.
Start with the questions
Before you collect a single hammer, answer a few questions in writing:
- Who is it for? Residents of a neighborhood, members of a club, or anyone? Membership rules shape everything else.
- What will it lend? Hand tools, garden tools, basic power tools, specialist equipment?
- Where will it live? Shelter, security, access and space all matter.
- Who runs it? A volunteer team, an existing organization such as a library or makerspace, or a mix.
- How will it be paid for? Donations, small membership fees, grants or a host organization. Be modest and realistic; do not assume the library will cover its costs.
Talking to potential members and looking at how existing groups work can save you from repeating common mistakes. Joining a nearby makerspace or an existing lending scheme to see how they do things first is a sensible step.
Choosing what to lend
Begin with simple, widely useful items. Hand tools such as screwdrivers, hammers, clamps, tape measures, saws and hand tools for basic woodworking are cheap, durable and low-risk. Garden tools and a few basic power tools can follow.
Think carefully before including equipment that is dangerous or easy to misuse:
- Tools that can cause serious injury with little experience.
- Items that need guards, dust extraction or special protective equipment.
- Anything with complicated setup, maintenance or consumables.
- Tools that need regular calibration, because a worn or unreliable one can be worse than none.
You can add an item later; it is harder to remove one that members have come to rely on. For power tools, many libraries lend them with a short briefing and the appropriate protective equipment, or require members to show they know how to use them. Guidance on power tool safety for beginners applies here.
Be honest about what the library does not cover. A tool library lends equipment; it does not make borrowers competent or qualified. Electrical, gas and structural work should still go to a qualified professional.
Donations and purchases
Donated tools are a common source, but quality varies. Check each one before it goes on the shelf: look for cracks, loose handles, missing guards, damaged cords and worn parts. Reject anything unsafe. Buying a few good-quality basics can be worth it, because durable tools survive many borrowers. Keep a record of where each item came from.
Tracking and lending rules
You need a simple way to know what you have and where it is. At minimum:
- A numbered label on every item.
- A list or spreadsheet with the tool, condition, date acquired and notes.
- A loan record showing who borrowed what and when it is due.
Set clear terms: how long items can be kept, what happens if they are returned late, damaged or lost, and whether a deposit or fee applies. Keep rules short and fair. A library that is hard to use will not be used.
Ask borrowers to confirm that they understand how to use the tool safely, and consider a short written agreement. Check what applies to you locally; this is general information, not legal advice.
Space, storage and organization
Plan the layout around how tools are stored and checked. Shelving by type, labeled bins and a visible check-in area help a lot. Good parts storage keeps small items such as drill bits, blades and batteries from disappearing. Store sharp tools safely, keep tools dry, and keep chargers and lithium batteries in line with sensible battery storage practice, away from combustible materials. Keep fire safety in mind in any shared space, including extinguishers and exits.
If the library lives in a space shared with other groups, agree who has access and who is responsible for locking up.
Maintenance
Tools wear out. Plan a routine to inspect them on return: clean, check for damage, sharpen cutting tools and replace worn parts. Skills such as tool sharpening are useful volunteer contributions. Record repairs and retire items that are no longer safe. Tools that cannot be fixed should be disposed of properly and not passed on.
A regular maintenance session can also double as a social event, giving volunteers a chance to learn from each other.
Liability and insurance
Lending equipment carries risk. Someone could be hurt using a tool, or a borrowed tool could damage property. Rules differ widely, and this is not legal advice. Before you start, ask a qualified adviser or an experienced local organization what cover you need for volunteers, premises and borrowers. Consider written terms of use, clear safety instructions with each tool, and a policy for refusing loans where a borrower seems unprepared.
Growing and sustaining the library
Start small and learn. A modest collection run reliably is better than a large one that is chaotic. Recruit volunteers early, share the workload, and make it easy for new people to take on a role. Track what members borrow most, what sits unused and what they ask for, then adjust. Over time, a tool library can also host workshops, skill-sharing evenings or repair events, strengthening the wider maker community.
