ADUs and permits
Los Angeles ADU and converted-space questions: verify the unit before relying on it
A guest house, garage conversion, bonus room, or advertised additional unit may create useful space, but the label does not prove the legal configuration, permit history, completed inspections, allowed occupancy, condition, value, rent, financing treatment, tax result, or insurance treatment.
Short answer: the name of the space proves almost nothing
California HCD's current ADU handbook describes statewide law and directs users to local requirements, while Los Angeles City and unincorporated Los Angeles County administer their own planning, permit, and inspection processes. First confirm whether the property is inside an incorporated city or an unincorporated county area, then use the responsible jurisdiction's current records and staff guidance.
- Exact address, assessor parcel number, legal description, and responsible planning/building authority.
- How the space is described in current permits, plans, inspection records, certificates, assessor information, title material, disclosures, leases, and insurance records.
- Whether the observed layout and use match the approved record.
- Which question requires an architect, engineer, contractor, inspector, attorney, tax adviser, appraiser, lender, insurer, or other specialist.
Search records without treating silence as approval
LADBS makes many City of Los Angeles permits, certificates of occupancy, inspection records, plans, and related records available, while LA County uses its own systems for unincorporated areas. A missing online result does not establish that work was unpermitted, and a permit entry does not establish that the built condition matches approved plans or that every required inspection was completed. Ask the responsible agency how to obtain the authoritative record.
- What work was authorized, under which permit number and scope?
- Which plan set or revision was approved?
- Which inspections are passed, pending, expired, cancelled, or unavailable online?
- What final, certificate, address assignment, or agency confirmation applies to the current configuration?
Compare the record with the physical property
Have the appropriate professionals compare the observed entrances, kitchens, bathrooms, sleeping rooms, utilities, meters, electrical service, HVAC, fire and life-safety features, drainage, setbacks, access, parking, structural work, and shared systems with the available record. A public-record search is not an inspection, engineering opinion, code-compliance determination, or cost estimate.
Separate current fact from future possibility
A property may have an existing approved ADU, an altered space, an application in process, or only possible future development. State law and local standards change, and site-specific overlays, utilities, access, fire, coastal, hillside, historic, environmental, or other conditions may matter. Do not price or market future work as completed until the responsible agencies and qualified professionals support that conclusion.
- Existing approved configuration and present occupancy facts.
- Open applications, corrections, fees, inspections, or enforcement questions.
- Future feasibility with current jurisdiction, design, utility, budget, and timing assumptions.
- Separate financing, appraisal, property-tax, rental, legal, and insurance review.
Preserve known facts and unresolved questions
Sellers and buyers should keep the permits, plans, invoices, contractor information, inspections, leases, notices, repair history, and known condition facts organized for transaction-specific review. LAREALTi does not legalize a unit, determine required disclosure, represent rent or value, verify authority, inspect construction, issue a permit, or guarantee that a proposed ADU can be approved.
