# Unit Takeoff

> [!important]
> Complete [[pre-takeoff-research]],
> including [[wiring-method-selection]] and [[wiring-device-research]],
> before beginning takeoff.

> [!info]
> See [[multi-family-dwellings]].

## Takeoff

> [!tip] Preparing for Unit Takeoff
> Units generally have very little variation.
> It is usually best to copy-paste takeoffs
> rather than re-build them for each unit.

1. Kitchen and Bath
2. General assemblies
3. Low Voltage
4. Lighting Fixtures
5. Lighting Control

> [!tip]
> It may be more efficient and neat to not copy switches,
> instead keeping the switch assembly list open
> and creating them new for each unit,
> since the types required can vary greatly between units.
