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 full ADU lifecycle: designing and permitting the unit, finding licensed contractors, 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 contractor bidding. A-du is built specifically for those pre-rental steps in addition to leasing and rent collection.

Why does A-du require identity verification?

A-du requires Stripe Identity verification before a user can list a unit or apply to rent one. This reduces fraud and scam listings, which are common on open marketing portals, and it is part of A-du trust-first model for both landlords and tenants.

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 platform from design through rent collection. 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 end-to-end ADU platform, 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 license-verified contractor bids. After: identity-verified tenants, FCRA-compliant screening with reusable portable profiles, e-signed leases, and rent collection where the landlord keeps 100% of the listed rent.

How to think about it

These tools are not mutually exclusive. A common pattern: build and permit your ADU with 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 owns the steps Zillow cannot, plus the relationship that starts a year earlier, when you first decide to build.
