Plan notes

Notes

Foundation notes
The City guide requires omitted site-specific foundation details and a State/HCD Design Approval Agency stamp for applicable factory-built plans; local site review remains required.
Utility notes
Site-specific utility routing and connection review remains required. New detached ADUs may require separate connections and proportional connection or capacity charges under current City code.
Energy notes
The City guide requires applicable Title 24 energy documentation and CALGreen information during plan pre-approval; project-specific compliance remains subject to City review.
Accessibility notes
The provider marks 'Accessibility features' in the City gallery. No independent accessibility-code compliance conclusion was inferred.
Permit fee notes
The adopted 2026–27 City schedule lists $1,455.43 for eligible manufactured, prefab, or pre-approved ADU review. Other site, utility, impact, professional, and construction charges may apply.
Cost notes
Conflicting provider-submitted City-gallery amounts: structured fields show $439,000–$498,500, while comments state a $268,800 base including unit, delivery, permitting, and standard site work. Verify before use.
Additional notes
City gallery catalog record a0APk000003ykCjMAI. The City-specific gallery lists the design as State of California (HCD)-certified, but it is not in the gallery's locally confirmed-plan-ID list. The controlled approval_status 'preapproved' records the external agency certification plus City listing; it is not parcel or building-permit approval. Phase 2 City site-specific review remains required, and the streamlined path does not allow design modifications. The direct document URL is a floor-plan image, not a complete permit-ready plan set. Provider-submitted gallery features: All-electric;In-unit washer/dryer;WUI (wildland urban interface) compliant;Solar-ready;Accessibility features;Turnkey project. No explicit public statement established that the plan license is free; plan_fee remains NULL.
