# Home Maintenance Score > Use a guided self-assessment of your maintenance records, preserve unknowns, and keep the supplied history with the next record update. [Canonical tool](https://makethisuseful.com/start/home-maintenance-score) This is a score of your maintenance records, not the condition or safety of your home. Unanswered questions are unknown, never failed equipment or inspection findings. Follow applicable manuals for actual maintenance work. ## Use your own information This is a guided self-assessment. You read your own document or notes, choose Recorded, Not recorded, Unknown, or Not applicable for each criterion, and enter the supporting wording or its location. The tool does not read, analyze, or verify a pasted or uploaded document. Start without an account. Your entries stay in this browser tab; available tab storage keeps them through refresh. The page tells you when storage is unavailable. Recorded means you found the information. Not recorded means you checked and it is missing from the document. Unknown means you have not established the answer. Not applicable is a deliberate exclusion. A blank answer never becomes a failed condition. ## Read and edit the assessment This is a score of your maintenance records, not the condition or safety of your home. Unanswered questions are unknown, never failed equipment or inspection findings. Follow applicable manuals for actual maintenance work. Each recorded criterion counts once. The percentage is recorded / (recorded + confirmed missing); unknown and not-applicable answers are excluded. The report always shows these counts alongside the percentage. If no applicable criteria have been checked, no percentage is given. This is a checklist of supplied information, not an independent verification. Take away the equipment identity, reported work, source locations, observations, and next record update you supplied. Each line retains its Recorded, Not recorded, Unknown, or Not applicable status. The tool does not infer completed work, a service interval, or equipment condition. Change answers to recalculate. Review the takeaway alongside your source, edit your assessment note and next steps, then print or choose Save as PDF in the browser print dialog. The Make your own link and QR open the blank tool; they do not carry your entries. ## Public example URLs GET /start/home-maintenance-score?example=starter displays an authored fictional example and its assessment in the initial HTML. Change example=complete for the completed example, or add focus=first-step for the first suggested next step. Supported values are example=starter|complete and focus=all|first-step. These parameters select only maintained public examples and settings. Add fresh=1 to begin a separate blank browser draft; the browser consumes that flag and keeps edits to the new draft through refresh. Other parameters do not enter the assessment. Do not put personal details, medicine text, addresses, or private documents into URLs. GET, HEAD, crawling, and prefetching do not submit work, call a model, publish an artifact, or incur generation charges. ## Visible criteria ### Equipment and manual locations Names or model labels and the location of applicable manuals are recorded. Next question: Record one equipment model label and where its manual can be found. ### Last known work The most recent known service date and work are recorded; uncertainty is labeled. Next question: Locate a service note or receipt and record its date and the work described. ### Source for the next check The next task refers to the applicable manual, service instruction, or recorded schedule. Next question: Find the applicable manual or service instruction before choosing the next check. ### Observations kept separate Observed issues, supplied negatives, and unanswered checks are clearly distinguished. Next question: Write only what was observed, who reported it, and what has not been checked. ### Service contact location A way to find the relevant service contact is recorded. Next question: Record where to find the service contact for the equipment you are organizing. ### Next task and owner A specific next record update and the person responsible are recorded. Next question: Choose one record update and who will do it; use a date only when you have one. ## Try the maintained public examples - [Fictional home maintenance record](https://makethisuseful.com/start/home-maintenance-score?example=starter): Authored fictional input and its initial assessment. - [Fictional home maintenance record: first next step](https://makethisuseful.com/start/home-maintenance-score?example=starter&focus=first-step): The same public example, focused on its first next step. - [Fictional home maintenance record with next step](https://makethisuseful.com/start/home-maintenance-score?example=complete): Authored fictional input and its initial assessment. - [Fictional home maintenance record with next step: first next step](https://makethisuseful.com/start/home-maintenance-score?example=complete&focus=first-step): The same public example, focused on its first next step. ## What the fictional starter example produces ### Home maintenance record Record: Fictional home maintenance record 2 recorded. 2 confirmed not recorded. 1 still unknown. 1 marked not applicable. ### Maintenance record you supplied The status describes the record. Unknown observations do not become equipment faults, and a reported visit does not establish unreported work. **Equipment and manual locations — Recorded** Air-handler model label photo and manual in the home folder. **Last known work — Recorded** Receipt records a filter replacement in April; year needs confirmation. **Source for the next check — Not applicable** No supporting text supplied. **Observations kept separate — Unknown / not checked** No supporting text supplied. **Service contact location — Not recorded — I checked** No supporting text supplied. **Next task and owner — Not recorded — I checked** No supporting text supplied. ### Next record updates **Observations kept separate — Unknown / not checked** First check whether this is recorded or applies; the answer remains unknown. Write only what was observed, who reported it, and what has not been checked. **Service contact location — Not recorded — I checked** Record where to find the service contact for the equipment you are organizing. **Next task and owner — Not recorded — I checked** Choose one record update and who will do it; use a date only when you have one.
