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 Texas under recent ADU streamlining laws. The Tyler, TX rules below cover local size, height, and setback requirements.

Full Breakdown

Tyler Unified Development Code Sec. 10-50 counts accessory dwelling units among allowed household-living use types, and the city expressly allows garage apartments across its residential zoning districts. Sec. 10-79(g), however, bars using any accessory building for dwelling purposes except a permitted garage apartment, so a shed or detached garage cannot become a rental unit without meeting garage-apartment standards and permitting. A garage apartment counts as an accessory structure subject to the 16-foot height limit and 5-foot side and rear setbacks. Texas sets no statewide ADU mandate; Tyler establishes its own allowances by zoning district.

Violations & Fines

Occupying an unpermitted accessory building as a dwelling violates the development code; the city can require a certificate of occupancy, order the use stopped, and cite the owner.
