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

Full Breakdown

Temple's Unified Development Code allows accessory dwelling units in nonresidential zoning districts only within the main structure: detached ADUs are prohibited outright. Outside the Central Area (CA) district, a lot gets just one ADU, capped at 49 percent of the main building's gross floor area, and only an employee of the on-site business and that employee's family may live there. Parking must be provided under UDC Sec. 7.5.4. In the CA district the one-unit cap is lifted, so more than one ADU per lot is allowed, with parking still required for each unit.

Violations & Fines

A detached ADU, a unit over the 49 percent floor-area cap, or occupancy by anyone besides the business's employee and family puts the property out of compliance with the UDC standard.

Frequently Asked Questions

Can I add a garage apartment to my nonresidential property in Temple?

Only if it's built into the main structure. Temple's UDC bans detached accessory dwelling units in nonresidential districts outside the CA zone, and caps the unit at 49% of the main building's floor area.

Who is allowed to live in the ADU?

Only an employee of the business occupying the main structure and that employee's family: the UDC restricts occupancy to keep the unit tied to the business use, not general rental housing.
