# Planned Maintenance (PPM)

> Recurring maintenance schedules that raise their own work orders.

Not all compliance is a once-a-year certificate. Fire alarms get tested weekly, emergency lighting monthly, water temperatures on a rolling schedule. Planned preventative maintenance (PPM) keeps these recurring tasks on cadence.

## Recurring Schedules

A PPM schedule raises its own [work order](/facilities/work-orders) on its cadence, so the task lands in front of the right person without anyone remembering to create it. Each completion is logged with the date, who did it, and the result (pass / fail / partial) — building the record an inspector expects.

Typical recurring checks:

* **Fire alarm** — weekly test, monthly function test
* **Emergency lighting** — monthly check, annual three-hour test
* **Water temperature** — monthly hot/cold monitoring (L8 / legionella)

## SFG20 Starter Set

Proprietas ships with a starter set of **SFG20** maintenance tasks — the industry-standard library for building maintenance — so you're not authoring schedules from a blank page. Apply the starter set to a site and tune from there.

<Note>
  PPM schedules and the SFG20 starter set are part of the Professional tier and above. See [Plans & AI usage](/billing/plans-and-ai-usage).

## How It Differs from Certificate Obligations

|          | Certificate obligation                 | PPM schedule               |
| -------- | -------------------------------------- | -------------------------- |
| Evidence | An uploaded certificate with an expiry | A logged completion        |
| Cadence  | Annual / multi-year typically          | Weekly / monthly typically |
| Raises   | A reminder, then a renewal work order  | A work order each cycle    |

Both feed the same status view, so a site's standing is one picture whether the requirement is a yearly EICR or a weekly alarm test.
