Quick Answers About Texarkana, TX ADUs
Market Context
Texarkana has a median home value of $180,000. Adding an ADU typically increases that by 22% — approximately $39,600 in added equity. A 1-bedroom ADU in Texarkana rents for approximately $870/month in the Bowie County rental market , yielding a 7% cap rate on the investment. Occupancy averages 88% in this market.
Top Texarkana neighborhoods for ADU investment include South Texarkana, Summerhill, Washington Historic District, Highland Park, West Highlands. Adjacent to Texas A&M University-Texarkana with steady student/faculty rental demand and abundant SFH lots supporting detached ADUs. Convenient to Texarkana College for off-campus student housing demand, with classic mid-century lots large enough for a backyard cottage.
Permit Process
Permit applications are reviewed by the Inspections and Code Enforcement . Permit fees in Texarkana range from $170 to $220 depending on project scope. Design review: Yes - in historic districts only
Because Texarkana straddles the Texas-Arkansas state line, some Bowie County lots sit close enough to the border that surveyors and title companies get confused about which state's easement rules and utility provider apply — double-check your plat before assuming Texarkana Water Utilities serves your address. The bigger snag is that Inspections and Code Enforcement processes ADU permits alongside regular single-family builds with no dedicated ADU track, so plan reviewers often flag detached units for a separate sewer tap fee if your existing line was sized for a single household, a cost that isn't listed on the city's fee schedule and gets quoted case-by-case. Since STRs aren't allowed here, be ready to show the reviewer your intended use is long-term rental or family housing, or your application can stall while they clarify occupancy classification.
"In my experience, both the timeline and cost-per-square-foot figures here are blank or missing because they're really just state-level placeholders, not actual Texarkana numbers — I'd call our Inspections and Code Enforcement office directly and get two or three local contractor bids before you pencil in a budget or schedule. With no verified plan check timeline listed, don't assume anything under 8 weeks; incomplete drawing sets are the norm on first submittal here, and that alone can add a month or more."

Property Eligibility
Is My Texarkana, TX Property Eligible for an ADU?
Texarkana homeowners are governed by Texas's local zoning ordinances — Texas has no statewide ADU-approval law. Here's what applies to your property before you start designing.
Single-Family Home
Permitted on single-family lots in Texarkana under Texas's local zoning ordinances — Texas has no statewide ADU-approval law. No owner-occupancy requirement in Texarkana — you can rent both units as investment properties. Review process and timelines are set entirely by local ordinance — confirm the current process with the Inspections and Code Enforcement before designing.
Multi-Family Property
Additional ADUs on multi-family and duplex lots may qualify under Texas's local zoning ordinances — Texas has no statewide ADU-approval law — the exact number and type allowed depends on Texarkana's local rules. Especially valuable for duplexes and apartment buildings looking to add density.
HOA-Governed Properties
Approximately 34% of Texarkana homes are in an HOA. Texas has no statute limiting HOA power over ADUs — HOAs can restrict or ban ADUs and short-term rentals through their covenants (Texas Property Code Ch. 202/204/209). Our drawings include HOA submission formatting.
Historic Districts
Yes - in historic districts only
Always verify eligibility with Inspections and Code Enforcement before designing.

Texarkana ADU Return Calculator — Built With 2026 Local Data
Pre-loaded with verified Texarkana construction costs, median rental rates, and property value uplift data. Adjust the inputs to model your specific project.
Your Project
Projected Returns
* Estimates only. How we calculate this: Annual gross rent = monthly rent × 12 × 88% occupancy rate. Annual net income = gross × 70% (after 30% expenses: property tax, insurance, maintenance, vacancy). Value added = median home value × 22% uplift (regional ADU comparables). Total return = net income × years + value added. Break-even = total build cost ÷ annual net income. Consult a licensed financial advisor before investing.
Data sources: Inspections and Code Enforcement (source ↗), Zillow Rental Market Reports, and public state/local housing data. Last verified: 2026-08-15.

Local Zoning Rules
2026 Texarkana ADU Rules
Texarkana's 2026 ADU ordinance caps new units at 1,100 sq ft and 25 ft of height — in the typical range most ADU floor plans are designed around. Setbacks run tight — 3 ft side / 3 ft rear — which leaves more of the lot buildable. Texarkana doesn't trigger the extra engineer-stamp requirement we see in higher seismic-risk or hurricane-code cities — a standard code-compliant ADU under the size cap can typically be designed and submitted without an architect or engineer stamp, though any load-bearing change to the existing house still needs one.
Permit fees run $170–$220 — notably inexpensive compared to most cities we cover through Inspections and Code Enforcement. Submit directly to the department online — link below.
| Regulation | Texarkana Allowance |
|---|---|
| Max ADU Size | 1,100 sq ft |
| Max Height | 25 ft |
| Side Setback | 3 ft |
| Rear Setback | 3 ft |
| Architect / Engineer Stamp | Not required under the size cap* |
| Owner Occupancy | Not required |
| Short-Term Rental | Restricted |
| Coastal Overlay | No |
| Design Review | Yes - in historic districts only |
| HOA Prevalence | 34% of properties |
| Permit Fees | $170–$220 |
*Load-bearing modifications to the existing house always need an engineer stamp regardless of ADU size. Data verified 2026-08-15T06:10:50.038Z. Always confirm with the Inspections and Code Enforcement before designing.

We turn your backyard into a rental unit. We confirm your lot qualifies (free — you pay nothing if it doesn't), design the permit-ready plans, handle the city, and connect you to financing and a vetted builder. One flat fee — about what an architect charges just to start. Yours would rent around $870/mo.
