Is A-du a replacement for Zillow?

For ADU owners, A-du replaces the parts Zillow does not cover and overlaps on the rest. Zillow is built to advertise a vacancy to a large audience and take applications. A-du covers the steps before and after the listing: choosing a plan and estimating permit fees, finding contractors and trades you hire directly, then listing, screening, leasing, and collecting rent. Many owners list on both and use A-du as the system of record.

Does Zillow help me build or permit an ADU?

No. Zillow is a rental marketing and application platform. It does not offer ADU plans, permit-fee estimates, GIS lot lookups, or a contractor and trades directory. A-du is built specifically for those pre-rental tools in addition to leasing and rent collection.

Why does A-du require identity verification?

A-du requires renters to verify their identity with Stripe Identity before they book, and landlords verify through Stripe Connect before they take rent through A-du. This reduces the fraud and scams that are common on open marketing portals.

Who is A-du best for?

A-du is best for homeowners and small landlords who own or are building an Accessory Dwelling Unit in a served market and want one account from plan to rental. If you only need to advertise an existing apartment to the widest possible audience, a large portal like Zillow is a reasonable complement.

A-du vs Zillow

A-du and Zillow are different categories of tool: A-du is an ADU marketplace with plan, permit, and rental tools, and Zillow is a large rental-listing marketplace that advertises vacancies and collects applications.

For an ADU owner the practical question is not which one wins, but which job you are doing: building and operating a unit, or simply advertising one.

The short version

Zillow is excellent at one thing: putting a vacancy in front of a very large audience of renters. If all you need is reach, it is hard to beat. But Zillow starts at the listing. It assumes the unit already exists and that you already know how to screen, lease, and collect rent safely.

A-du is built for the part of the journey that happens before and after the listing, specifically for Accessory Dwelling Units. Before: pre-approved ADU plans, permit-fee calculators, GIS lot lookup, and a directory of contractors and trades you hire directly. After: identity-verified tenants, FCRA-compliant screening with reusable portable profiles, e-signed leases, and rent collection. Listing is free, the first 15 published listings pay 0% landlord service fee, locked permanently, and other listings pay a 3% platform service fee on rent collected through A-du.

The A-du rental workflow in four steps: verify identity, screen fairly, sign the lease, collect rent — What happens after a renter clicks your listing on A-du.

How to think about it

These tools are not mutually exclusive. A common pattern: choose your plan and estimate permit fees on A-du, run screening and the lease through A-du so it is your system of record, and syndicate the listing to a large portal like Zillow for extra reach. The difference is that A-du covers the steps Zillow does not, plus the relationship that starts a year earlier, when you first decide to build.
