Yet another apartment complex addressing question.

Hi all, I'm trying to improve the address tagging for this apartment complex.

Here are the facts on the ground:

• The whole complex has one house number, 23411 Summerfield.
• Within the complex there are around 50 buildings, each with its own building number, e.g., Building 12
• Apartments' postal addresses are based on a building number and unit letter. So an example address would be 24311 Summerfield Apt. 42B.
• Mail to the building management office is just addressed to 23411 Summerfield, with no unit number.
• In most buildings, each unit has its own building entrance.
• Many units have both a pedestrian entrance and a garage entrance. Some units have an assigned garage in a separate building.

Currently we have ways for the complex as a whole and for each building, and I expect we'll want to add entrance nodes for apartments with private entrances. Also there are currently address tags on the buildings but they were imported and I claim they're incorrect.

So my questions are:

• What address tags, if any, should be populated on the landuse=resedential node linked above?
• What address tags, if any, should be populated on the individual buildings? Note that with the exception of the management office, no building corresponds to a single postal delivery point.
• What address tags, if any, should be populated on pedestrian apartment entrances?
• What address tags, if any, should be populated on garage apartment entrances?
