The unfortunate thing is there is no density bonus payments for laneway houses, so the bonus density payment between 0.70 to 0.85 is in reality just a tax on multiplexes, disincentivizing multiplexes.
For example, on a 5000 sq foot lot, a developer could build a 3000 foot home + 1250 sqft laneway house (total 4250sqft) without any density bonus payments.
However in order to build a multiplex of the same FSR (0.85 FSR) they would pay up to $105000 in additional bonus payments ($140*750sqft)
