Frequently Asked Questions
Can I build an ADU on my Arlington property?
Yes. Arlington's Unified Development Code allows accessory dwelling units in single-family residential zones. Detached ADUs are limited to 800 sqft. Texas has no statewide ADU preemption law, so Arlington's local UDC governs. You'll need a permit from Arlington Development Services and must comply with setback and lot coverage requirements.
Why doesn't Arlington have public transit?
Arlington is one of the largest US cities without a public transit system — a deliberate choice reflecting its suburban development model. The city is entirely car-dependent within city limits. The TRE (Trinity Railway Express) connects the region's downtowns (Dallas and Fort Worth) but has no station in Arlington. This means any planning for ADUs or commercial development must account for car parking needs. The city has discussed transit options for years, particularly for major events at AT&T Stadium.
Are short-term rentals allowed near AT&T Stadium?
Yes, short-term rentals are allowed in Arlington with registration ($150/year). Properties near AT&T Stadium and Globe Life Field can be highly lucrative for event-night rentals. However, you must have an STR registration number posted in all listings. Event-related parking restrictions and crowd management near the entertainment district may affect access during Cowboys and Rangers games. Arlington Hotel Occupancy Tax (HOT) applies to all STR rentals.
What solar incentives are available in Arlington?
Arlington is in the ERCOT deregulated electricity market, meaning you choose your own retail electricity provider. This gives solar homeowners the freedom to select a provider with favorable solar buyback rates. You'll need an electrical permit from Arlington Development Services and an interconnection agreement with Oncor Electric (the local transmission and distribution company). Texas has no state solar mandate, but solar is cost-effective in North Texas with approximately 230 sunny days per year.
How do I find my zoning in Arlington?
You can find your zoning designation using Arlington's online GIS zoning map at the Planning Department website. Your zoning determines what you can build, setback requirements, height limits, and lot coverage allowances. The Arlington Unified Development Code (UDC) explains all regulations for each zone. Contact Arlington Planning at (817) 459-6502 with specific questions.
