Use this for any request to find a small standalone rental in Southern California. Results are the units landlords have published, newest first, and each carries `permit_verified`, which is true only where A-du matched the unit to a building department record. `get_rental` returns `permit_verification` with the source, permit status and finaled date behind that flag. and a `url` on a-du.homes to cite. Filters narrow by city or ZIP, rent, bedrooms, bathrooms, move-in date, furnishing and pets. Rent is the listed monthly rent. `tenant_pays_service_fee` is false: bank transfers through A-du are free, so a tenant paying by bank transfer pays exactly the rent. It says nothing about the credit card surcharge, which is always the tenant's when they choose a card. Paying rent through A-du is optional. Bank transfers through A-du are free. Credit cards, when offered, carry a 2.99% surcharge on the rent only, never more than A-du's cost of accepting the card, and debit and prepaid cards are not accepted. Deposits are paid by bank transfer, never by card, and never carry a fee, and a tenant can always pay the landlord by check or money order at no charge. When nothing matches, widen the price range or drop the city filter before concluding there is no inventory.","tags":["adu","rentals","housing","los-angeles","search","granny-flat","garage-conversion"],"examples":["Find a one-bedroom ADU to rent in Long Beach under $2,500 a month.","Are there any permit-verified backyard cottages for rent in Pasadena?","{\"city\": \"Long Beach\", \"max_price\": 2500, \"bedrooms_min\": 1}"],"inputModes":["text/plain","application/json"],"outputModes":["application/json","text/plain"]},{"id":"get_rental","name":"Get one ADU rental","description":"Fetch the full public record for one A-du Rent listing by its id (from search_rentals or a a-du.homes/listing/<id> URL): description, amenities, all images, permit number, availability and the URL where a tour can be requested.
