So let me summarize everything many people concerend in this thread.
The only technical/legal difference between true SFR and IP's single detached condo is whether a house/building has a dedicated lot (lot number) or shared lot.
For example, the lot size of my Saratoga home is sitting on (let's say lot "A") is 12,160 sqft. You cleary see it's a large lot. However, lot "A" is shared by 4 detached condo owners (my neighbors). IP equally divided lot "A" into 4 portions. They call each individual portion as a "Unit". So each detached condo onwers have 3,040 sqft unit size (38'X80'). (In general, people normally call it "lot size" as same as true SFR's lot.)
And detached home owners have exclusive ownership withint this 3,040 sqft unit boundary.
More specifically, IP's detached condo ownership includes:
a) 3,040 sqft of the land downward to the center of the earth and upward to at least 50 feet above the earth's surface.
b) all improvements constructed inside 3,040 sqft unit boundary.
c) a undivided fractional fee interest in the "Common Area" such as shared path way and motor court drive way.
d) all easements (exclusive and non-exclusive) appurtenant to the respective Condominium Unit
All of these above were written/specified in the sales contract, Condo Unit Plan and additional Annexation docs.
So it's technically same as SFR but homes just don't have separate lot number and exclusive lot lines.
In the contract docs, first line of ownership section starts with
"Your condominium is essentially equivalent to a traditional detached single family home located on a separate lot because each owner in the Neighborhood will own a detached single family home"
So IMO, "unit" is just a small lot (Normally less than 3,500 sqft) to squeeze more detached homes under city's legal requirement.
And we're seeing this minimum lot size is getting smaller by IP's effort. (For example, some of true SFRs in CV have 3,400 sqft lot size with 10ft rear setback)
