Zoning in Baytown, plainly

The map

What you can build, open or park on a lot, and where to find out before you buy.

The city's zoning map is on the Baytown GIS hub, and it's linked in the Sources below. Type an address and the parcel's district comes up: residential by density, commercial, industrial, mixed-use downtown, and the overlays. The city's long-range plans page says the current future land use map and the zoning map both live in that GIS map. Mont Belvieu has its own map and its own code. Highlands and Crosby are unincorporated Harris County, which has no zoning at all. Deed restrictions and the county's development rules do the work there.

The code behind the map

Baytown's zoning and subdivision rules sit in one document, the Unified Land Development Code (the ULDC), and the city's Planning and Zoning page points to the 2025 version as the current one. An older 2014 version is still posted for reference, but it has been superseded, so do not quote it. The 2025 code does not print an effective date on the page, so cite it as "the 2025 ULDC" and ask for the section number. The bigger picture is the Baytown 2040 Comprehensive Plan, which City Council adopted in May 2022. It is the document that says where the city expects to put homes, shops and industry, and it is the place to look if you want to know what a vacant lot next door might become.

What the districts mean, roughly

Single-family residential districts set lot sizes and what accessory buildings you can add. The multifamily districts are where the apartments go. The commercial corridors are Garth, 146 and Decker. The heavy-industrial districts hug the plants and the channel. The ACE District downtown has its own mixed-use rules, which is why apartments, bars and shops can share a block of Texas Avenue in a way a residential street cannot. Town Square, at 213 W. Texas Avenue, is the ACE district's lawn and the easiest place to see what mixed-use looks like on the ground. The exact permitted-use table is in the ULDC itself, and the district name on the GIS parcel map tells you which column of that table applies to your lot.

Permits: the two that surprise people

Zoning says what a lot can be used for; a permit says you may build the thing. Two rules from the city's permit pages come up constantly. A fence installation or replacement of 50 percent or more needs a permit, and the fee is $67. Repairing less than half of a fence does not. A swimming pool 24 inches deep or more needs a permit, and the fee is $620 including the mechanical, electrical and plumbing permits. Sign permits are charged by the square foot, at $0.67 per square foot. Both the fence and pool fees come from the city's schedule effective June 1, 2026. The city's new fiscal year began October 1, 2026, and fees change, so confirm the current number before you pay. The Permit Center at 2401 Market Street takes applications, and Planning and Development Services in the same building keeps the hours above.

The questions people actually have

• Can I run a business from my house? Home occupations are a section of the ULDC, not a yes or no, and the limits differ by district. Ask Planning for the section and the rules for your district.
• Can I park the RV or the boat in the driveway? It depends on the district and, more often, the HOA. HOAs, especially on newer subdivisions, are often the stricter of the two, so read your deed restrictions first.
• Can I build a shop or a garage apartment? Accessory structures carry size and setback limits, and a second dwelling is district-specific. Bring the parcel's district name from the GIS map when you ask.
• Chickens? The animal ordinance decides, not the zoning map, and it is linked from the city-hall page.
• Short-term rentals? Ask Planning first, and check the council's decisions list for recent votes.

The 2025 code replaced the older text, and we would rather send you to the current section than quote a limit we cannot confirm. So ask Planning and Development Services which district your lot is in and for the section number, and ask for the answer in writing.

Rezoning and variances

The Planning and Zoning Commission hears rezoning requests and the Board of Adjustment hears variances. Agendas are on the city's portal, and neighbors get notice by mail. The council's recent decisions on the city-hall page show what has been rezoned lately.

An hour in that room tells you more about where the town is going than any listing.

Outside the city limits

Texas counties cannot adopt zoning, with narrow statutory exceptions, so unincorporated Harris and Chambers County land is not zoned. What counties can regulate is narrower: subdivision platting, building codes, septic systems, some floodplain and nuisance rules, and roads. That is why a house in Highlands or Crosby can end up next to almost anything, and why deed restrictions are the real zoning there. Ask the title company for the restrictions before you close, and ask the MUD or HOA what it enforces.

Before you buy

Pull the district, read the deed restrictions, ask the HOA, and check the flood map on the hurricane page. The flood map decides more than the zoning does on the Bayway side. Baytown's Community Rating System class is 5, which FEMA ties to a 25 percent discount on flood insurance premiums in the special flood hazard area. So ask your agent what an address will actually cost. Baytown City Hall at 2401 Market Street is the front door for all of it, and Baytown Engineering shares the address for engineering questions. Mont Belvieu City Hall at 1 Town Center Boulevard is the door for that city's own map and code.

Before you go

• Look up the parcel's district on the GIS map before you make an offer, not after.
• Read the deed restrictions and the HOA rules, because they are often stricter than the city's.
• Ask Planning and Development Services for the code section behind any answer you plan to rely on.
• Check the flood map and ask an insurance agent for a quote before you commit to a Bayway-side address.

Questions people ask

How do I find the zoning for an address in Baytown? The GIS map, linked; type the address.

Is Highlands zoned? No. Unincorporated Harris County has no zoning; deed restrictions apply.

Zonificación en Baytown, en palabras sencillas

La zonificación de Baytown responde qué se puede construir o hacer en un terreno dentro de los límites de la ciudad. Empiece por el mapa de la ciudad, escriba la dirección y después lea el código y las reglas de permisos que se aplican a esa propiedad. La oficina de Planificación y Desarrollo está en 2401 Market Street y abre de lunes a jueves de 7:30 a.m. a 5:30 p.m., y los viernes de 7:30 a 11:30 a.m.

El mapa y el código

El mapa de zonificación está en el portal GIS de la ciudad. Al escribir la dirección aparece el distrito del terreno. Las reglas están en el Código Unificado de Desarrollo Territorial (ULDC) de 2025; la versión de 2014 ya fue reemplazada, así que no la cite. El Plan Integral Baytown 2040, adoptado por el Concejo en mayo de 2022, dice dónde espera la ciudad poner viviendas, comercios e industria. Mont Belvieu tiene su propio mapa y su propio código. Highlands y Crosby están en el condado de Harris no incorporado, que no tiene zonificación: allí rigen las restricciones de escritura y las reglas de desarrollo del condado. Los condados de Texas no pueden adoptar zonificación, salvo excepciones muy limitadas.

Permisos

Una cerca nueva o de reemplazo de 50 por ciento o más necesita permiso, y cuesta $67. Reparar menos de la mitad no lo necesita. Una piscina de 24 pulgadas o más de profundidad necesita permiso, y cuesta $620 con los permisos mecánico, eléctrico y de plomería incluidos. Los permisos de letreros se cobran a $0.67 por pie cuadrado. Estas tarifas son del calendario vigente desde el 1 de junio de 2026; el año fiscal de la ciudad empezó el 1 de octubre de 2026, así que confirme la cifra actual antes de pagar.

Preguntas comunes

Los negocios en casa, los RV o botes en la entrada, los cuartos o talleres adicionales, las gallinas y las rentas de corto plazo dependen del distrito, de la ordenanza de animales y de la asociación de vecinos. Pregunte a Planificación y Desarrollo en qué distrito está su terreno, pida el número de sección del código y pida la respuesta por escrito. La Comisión de Planificación y Zonificación atiende las solicitudes de cambio de zonificación y la Junta de Ajustes atiende las variaciones; los vecinos reciben aviso por correo.

Antes de comprar

Busque el distrito en el mapa, lea las restricciones de escritura, pregunte a la asociación de vecinos y revise el mapa de inundaciones. Baytown tiene clasificación 5 en el Sistema de Clasificación Comunitaria de FEMA, que equivale a un descuento de 25 por ciento en el seguro contra inundaciones en las zonas de riesgo especial. Pida a su agente el costo real de la dirección. El Ayuntamiento de Baytown está en 2401 Market Street, y el de Mont Belvieu, en 1 Town Center Boulevard.
