Where, and what?
Los Angeles · City of Los Angeles, if the parcel is inside city limits · unverified
A “Los Angeles” mailing address or ZIP code does not prove the parcel is inside the City of Los Angeles; postal names cross city and unincorporated county lines.

Los Angeles
Bring
Address and parcel, existing permits, proposed ADU type and site drawing. For the Standard Plan path: title/area sheet, plot plan and approved plan.
First agency and action
City Planning checks zoning and overlays; LADBS handles building plan check. Check the parcel with City Planning, then use the LADBS ADU standard-plan submittal checklist if choosing that path.
Question to resolve
Coastal, hillside, fire, specific-plan and utility conditions require the address and design; later state changes must be checked separately.
Parcel boundary and owner records, existing plans, site survey and intended ADU type; for preapproved plans, show setbacks, easements, utilities, sewer, drainage and emergency access.
First agency and action
Community Development Planning is the first contact; Building & Safety reviews the building permit. Ask Planning which city ADU development guide applies; use the Property Owner Submittal Checklist for a preapproved design.
Question to resolve
Hillside, Trousdale, historic, fire and utility review cannot be assigned from a mailing address or a catalog design.
Parcel address, existing home and proposed ADU type, lot measurements and any coastal or historic designation; a sloped lot may need a survey.
First agency and action
City Planning publishes the single-unit parcel guide; Community Development handles building-permit intake. Coastal review may add another authority. Use the November 2025 single-unit-parcel ADU guide to identify the building-permit path and check coastal status before submittal.
Question to resolve
Coastal boundary, historic listing, slope and design-specific plan check remain parcel-dependent.
Address, parcel and owner record, existing conditions, scope and site drawing; confirm the latest application attachments directly with the city.
First agency and action
Planning & Development confirms zoning and the ADU path; Building Safety handles building-plan intake. Consult the city ADU handbook and building-permit application page before opening a permit request.
Question to resolve
City pages restricted automated access at review. Current intake attachments, overlay conditions and any design review for this address are not verified here.
Address, parcel and existing permits, site plan, proposed ADU type and any historic or hillside designation; the city's single-family, junior and multifamily ADU pages set out the applicable standards.
First agency and action
Planning & Community Development handles zoning consultation; Building & Safety reviews building plans. Book the city's ADU virtual consultation for zoning feedback, then apply and upload plans through the city's online e-permitting service.
Question to resolve
Historic district or landmark review, hillside conditions and parcel-specific requirements are not determined by the standard plan and must be confirmed for the address.
Parcel and existing permits, site plan, ADU type, access and utility-service information; ask which documents the chosen plan path requires.
First agency and action
Building & Safety coordinates building-plan check; Public Works and Burbank Water & Power may review address and utility work. Open the city ADU page and confirm Building & Safety's current plan-check and intake requirements before selecting a preapproved plan.
Question to resolve
The live city pages refused automated reads; the review used the 7 Aug 2026 Internet Archive copy. Whether the 2023 ordinance reflects 2025–2026 state changes, the current checklist, hillside/geotechnical triggers and utility capacity are not verified for any parcel.
