ADU Eligibility Quick-Check

An Accessory Dwelling Unit (ADU) is a smaller, independent living unit on the same lot as a single-family home: converted garages, detached cottages, basement or attic conversions, and attached additions all qualify. Most states have streamlined ADU permitting since 2020, but local rules still control size, height, and setback.

Is your lot zoned single-family or multi-family residential?
Does your lot have at least 1,200 sq ft of buildable space?
Is your existing home owner-occupied (in most states this is not required, but some require it for ADU permits)?
Will the ADU stay under your state's size cap (commonly 850-1,200 sq ft for detached)?
Can you provide one off-street parking space (waived in many states within 0.5 mi of transit)?

If you answered 'yes' to most of these, you likely qualify in Kansas under recent ADU streamlining laws. The Wichita, KS rules below cover local size, height, and setback requirements.

Full Breakdown

The Unified Zoning Code defines an Accessory Apartment as a second dwelling unit that can sit inside or be detached from a principal single-family home. It's listed as a Conditional Use in the RR, SF-20, SF-10, SF-5 and TF-3 residential districts, meaning owners need Planning Commission review and approval under Sec. V-D before building or converting one. Only one accessory apartment is allowed per lot, it must match the main house and neighborhood in appearance, it has to stay under the same ownership as the principal home (no condo-style split-sale), and water/sewer service can't be split into a separate account from the main dwelling.

Violations & Fines

Building or occupying an accessory apartment without the required Conditional Use approval is a zoning code violation subject to code enforcement action, including a stop-work order and required removal or conversion of the illegal unit.
