Hotel
[!info] Also Known As

[!trivia] The term "key" as a synonym of "hotel room" is a synecdoche, referring to the unit's door key. In the pre-digital days of hotel management, one could count the rooms of a hotel by the keys behind the front desk.
Residential
[!info] Also Known As
- Condos - resident-owned
- Apartments - resident-rented
Sequence
1. Preparation

2. 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.
- Kitchen and Bath
- General assemblies
- Low Voltage
- Lighting Fixtures
- 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.
