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
Not listed in source
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. Because the listed area exceeds 750 square feet, proportional development impact fees may apply under current City code.
Cost notes
Provider-submitted City-gallery range. A project-specific foundation, soils report, and listed finish/accessory options can add cost.
Additional notes
City gallery catalog record a0APk00000F3GfVMAV. 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. Bathrooms source value '2+' is a range/open-ended value and was preserved here rather than forced into the scalar column. No explicit public statement established that the plan license is free; plan_fee remains NULL.
