Building Setbacks & Zoning in Arlington, TX: What Residents Actually Need to Know

If you live in Arlington or are thinking about moving there, building setbacks & zoning are one of those things you probably won't think about until they affect you directly. Arlington has 2 specific rules on the books covering different aspects of building setbacks & zoning, and some of them might surprise you.

Setback Rules

Arlington sets front setbacks as the greater of the applicable sub-district standard or the minimum needed to meet sidewalk and Furnishing Zone requirements. Side and rear building projections must stay at least 5 feet off any non-street property line, and the Zoning Administrator can grant only narrow, capped adjustments through a Minor Modification.

Key details: Front setback rule: Greater of sub-district or sidewalk-zone standard. Side/rear projection limit: Min. 5 feet from property line. Minor Modification setback increase: Up to 10%, capped at 5 feet. Minor Modification setback decrease: Up to 2 feet. Curb-to-facade floor: Must stay at least 15 feet.

Setback and encroachment compliance is checked by the Development Services Department at building permit review; construction inside the required setback or closer than 5 feet to a side/rear line without an approved Minor Modification triggers a stop-work order and can require the encroaching portion to be removed or relocated before a certificate of occupancy issues. Modifications beyond the Minor Modification caps require a formal variance or FBZD amendment process, not administrative approval.

Structure Height Limits

Arlington's Form-Based Zoning Districts cap new building height at 45 feet within 75 feet of a shared line with a Traditional Neighborhood sub-district or any existing single-family zoning outside an FBZD. Beyond that 75-foot buffer, the full sub-district maximum height applies, measured under UDC Section 4.1.7.

Key details: Height cap near residential: 45 feet within 75 feet of the shared line. Beyond the buffer: Full sub-district max height applies. Height measurement standard: Per UDC Section 4.1.7. Required pairing: Screening per Section 13.1.9.B.5. Effective date: UDC Ord. 26-019, June 1, 2025.

Height compliance is verified by Development Services at plan review and again at framing inspection; a structure that exceeds 45 feet within the 75-foot residential buffer without the required screening or a Minor Modification approval can be denied a building permit or ordered to remove the offending stories before occupancy is granted.

The Bottom Line

Arlington's building setbacks & zoning rules are a mixed bag. Some areas are strict, others are relaxed, and the details matter. The best approach is to check the specific rule that applies to your situation rather than assuming Arlington is broadly strict or permissive.

Keep in mind that Arlington can amend these rules at any council meeting. For the most current version of any rule mentioned here, check the specific ordinance page, where we track updates as they happen.
