SB 1211 for Duplex in Escondido
In Escondido, a 2-unit duplex just became one of the highest-yield SB 1211 typologies — 3 new homes, ministerially approved. At Escondido's median rent of $2,200/mo, that's ~$79K in additional gross annual rent.
The Escondido scenario
The capital stack on a typical Escondido duplex project: existing equity (the lot itself, owned outright in many cases), construction loan against the new ADU appraised value, refi at completion against the stabilized rent roll.

Small multifamily (2–4 unit) design playbook
Small multifamily lots are usually constrained on width before they're constrained on count. With a 2-unit existing footprint, the binding constraint becomes side-yard setbacks (4 ft min) and the 18-ft height limit. Two-story stacked-flat ADUs over surface parking are the highest-yield typology.
