№ 02 — Questions
Alameda East End ADU questions, answered.
Is the Historic Advisory Board mandatory?
Yes — for any new exterior structure visible from a public street. Two-meeting cycle, typically 8–10 weeks.
Bay-fill soil — extra cost?
$8K–$20K for engineered foundation depending on bearing capacity report results.
Sea-level rise considerations?
Alameda requires finished floors 18" above 100-yr flood elevation on west-end lots — affects East End rarely.
