Zoning in Aransas County, Texas

A law written for this county specifically

Local Government Code Chapter 231 lists only a handful of named exceptions to the rule that Texas counties can't zone -- Padre Island (Cameron and Willacy Counties), land near certain military installations, and a short list of named lakes and recreation areas. Aransas County is on that short list too, added by Senate Bill 2555 during the Texas Legislature's 81st Regular Session in 2009, which inserted Subchapter N into Chapter 231. The bill's own findings spell out why: the Legislature determined that the parts of Aransas County surrounding Aransas Bay, Copano Bay, St. Charles Bay, Mesquite Bay, Carlos Bay, and Port Bay are used for recreation by residents from every part of the state, and that without development regulation the county risked being developed in ways that would harm public health, safety, and its value as a place of tourism and recreation.

The authority granted is geographically bounded, not countywide: Subchapter N applies only to unincorporated Aransas County land within three miles of the shoreline of the Gulf of Mexico or a bay. Outside that three-mile coastal band, the general Texas rule against county zoning still applies. Within it, the Commissioners Court may regulate the height and number of stories of buildings and other structures, the percentage of a lot that buildings may occupy, and the size of yards, courts, and other open spaces -- the classic tools of a bulk/dimensional zoning code, not a full land-use zoning map with residential/commercial/industrial districts.

Authority granted, versus an ordinance actually adopted

It's important to separate two different questions: whether the Legislature gave Aransas County the power to zone its coastal band (yes, since 2009), and whether the county's Commissioners Court has actually adopted a specific zoning ordinance exercising that power, with a map of current districts and dimensional standards, as of today. This research confirmed the statutory authority and its scope directly from the bill text and Local Government Code summaries, but did not independently locate and review a current, adopted Aransas County zoning ordinance or map exercising Subchapter N authority. Before treating a specific coastal parcel as subject to (or exempt from) zoning, confirm directly with the Aransas County Commissioners Court or Planning office whether an ordinance is currently in force, what district the parcel falls in if so, and what height, lot-coverage, and setback limits apply.

What this means for a coastal Aransas County buyer

1. Measure the specific parcel's distance from the Gulf of Mexico or bay shoreline -- Subchapter N's authority applies only within three miles of that line, so a tract further inland is governed by the county's ordinary (non-zoning) subdivision and floodplain rules instead.
2. Ask the county directly whether a zoning ordinance is currently adopted under Subchapter N, and if so, request the current zoning map and district regulations for the specific parcel.
3. If a zoning ordinance is in force, confirm height, lot-coverage percentage, and yard/setback requirements before finalizing plans for a structure near the coast -- these are the specific dimensional limits the statute authorizes the county to set.
4. Don't assume Aransas County's coastal zoning works like a city's full land-use zoning code -- the statute's granted powers are limited to building bulk and placement standards, not a comprehensive residential/commercial/industrial district map.
