The house-hack angle

SFH room rentals and ADU adds near the two-line transfer; the TOD plan's 5,000-unit EIR capacity raises the long-run ceiling while approved construction stays modest.

What breaks it

• The re-plan runs through 2027: the EIR capacity is still a plan
• Approved construction (~500 units) is a fraction of the 5,000-unit ceiling
• City-proxy rents: re-comp at the property level
