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 Pearland, TX rules below cover local size, height, and setback requirements.

Summary

Pearland regulates accessory dwelling units through its Unified Development Code, requiring a Conditional Use Permit before construction in residential districts and prohibiting ADUs in most commercial zoning districts.

What are the requirements to construct an Accessory Dwelling Unit (ADU)? Accessory Dwelling Unit is defined as: A subordinate building that is detached from the primary on-site structure, is used as a residence, is incidental to the main structure (i.e., the building area must be significantly less than that of the main structure) and is not involved in the conduct of a business. If the property is in a residential district, A Conditional Use Permit (CUP) is required to be applied for and approved by the Planning & Zoning Commission and the City Council prior to any construction. If the property is located in a commercial zoning district, a CUP is required for the Cullen-Mixed Use District, Garden-O'Day Mixed Use District and Residential Retail Nodes District. All other commercial zoning districts prohibit ADU's. Click the link to learn more about how to submit for a CUP: Zone Change
