County business license guide
Last updated: October 2, 2026
Montgomery County is one of the fastest-growing large counties in the country. The U.S. Census Bureau estimated 781,194 residents on July 1, 2025, up 30,011 in one year. Growth brings new storefronts, home businesses, contractors, food sellers, and service companies into a county where the first licensing question is often not “Which county license do I buy?” but “Which government controls this exact address and activity?”
This guide maps the county, city, special-district, Texas, and federal layers so you can find the right office before signing a lease, remodeling a space, buying a food truck, or assuming that a Conroe, Magnolia, Montgomery, Willis, or The Woodlands mailing address tells you the legal jurisdiction.
Bottom line
Montgomery County’s current business resources do not show one universal county business license for every business. Instead, the county has several important functions that can matter a great deal: land-development and floodplain permitting, fire-code review in unincorporated areas and certain cities, consumer-health and food permitting, on-site sewage work, assumed-name filings for applicable businesses, and county certification in the Texas other regulated activities process.
Your first job is to identify the jurisdiction of the physical address. Inside an incorporated municipality, the city may control zoning, building permits, a Certificate of Occupancy, signs, and activity-specific permits. In unincorporated Montgomery County, county development, fire, environmental-health, septic, and floodplain rules can become the main local layer. The Woodlands is a special case: it is not a normal incorporated city, but Township covenants and standards can still require property approvals.
Two 2026 changes to know before you file
Texas business filings moved to SOSPortal. The Texas Secretary of State launched SOSPortal on September 29, 2026 to replace SOSDirect and SOSUpload for business filings, orders, and searches. If an old checklist tells you to start a new entity filing in SOSDirect, use the Secretary of State’s current business-filing guidance instead.
Mobile food licensing became statewide. Beginning July 1, 2026, Texas DSHS requires mobile food vendors operating a food vending vehicle to hold the new statewide DSHS license. The old model of obtaining a separate local health license in every jurisdiction no longer controls mobile-food licensing, although local zoning, fire, event, and other lawful requirements can still apply.
Quick start: do these checks in this order
- Pin down the exact address. Use Montgomery County GIS Maps & Open Data, then confirm with the city if the parcel is near a city-limit or ETJ boundary.
- Decide who controls land use and the building. Inside a city, start with that city’s development or permitting office. For unincorporated property, start with the Montgomery County Permit Department.
- Check county functions that may cross city lines. Fire review, food/health, assumed names certification, and other county functions do not all follow the same boundary rule.
- Classify the activity. A consultant, restaurant, contractor, child-care operation, mobile food vendor, salon seller, and home business can follow very different state and local paths.
- Do the Texas layer. Form a filing entity if you choose one, handle the correct assumed-name route, register for Texas taxes when required, and check state occupational or industry licensing.
- Handle employer and federal steps. If you hire, check Texas Workforce Commission unemployment-tax duties and Texas new-hire reporting. Get an EIN directly from the IRS when your business needs one.
Montgomery County jurisdiction matrix
This is the key map. “Located in Montgomery County” does not mean “regulated only by Montgomery County.” Different layers control different tasks.
| Issue | Inside an incorporated municipality | Unincorporated Montgomery County | Texas layer |
|---|---|---|---|
| General/basic business license | City-specific. Check the city’s own license, registration, zoning, occupancy, and activity rules. | No universal county business license was found on the county’s current business-resource pages. Activity and property permits may still apply. | Texas does not require one general statewide business license, but regulated activities can require state licenses. |
| DBA / assumed name | County filing can still apply to an eligible non-filing business operating in the county; city rules are separate. | Montgomery County Clerk handles assumed-name certificates for applicable non-filing businesses. | Corporations, LLCs, limited partnerships, and foreign filing entities use the Secretary of State route. |
| Zoning / allowed use | Municipality usually controls its zoning and land-use rules. | Do not assume city zoning applies. County development/floodplain rules, deed restrictions, utilities, and other controls may still affect the property. | State law can limit municipal authority, including protections for qualifying no-impact home businesses. |
| Building / occupancy | City building and occupancy process usually applies. Conroe, for example, uses city building permits and Certificates of Occupancy. | County development permitting and other county reviews may apply; the path is not a city-style CO process. | State-adopted or referenced codes and licensed-trade rules may add another layer. |
| Fire | City-specific, except Montgomery County Fire Marshal expressly covers Cut & Shoot, Magnolia, Montgomery, and Willis under the county fire-code system. | Montgomery County Fire Marshal administers the county fire code in all unincorporated parts of the county. | State fire and occupational rules can also apply to particular facilities or activities. |
| Food / health | Confirm the health authority for the exact address and activity. Several local processes route commercial food work to Montgomery County Environmental Health. | Montgomery County Consumer Health is a central food-establishment and temporary-event permit route. | Since July 1, 2026, mobile food vendor licensing is statewide through DSHS. |
| Home business | City rules apply, but Texas law restricts municipal licensing, permit, and rezoning requirements for qualifying no-impact home-based businesses. | County fire, development, food, septic, and other activity rules may apply; private deed restrictions can matter. | Texas Local Government Code §229.902 protects qualifying no-impact businesses from specified municipal restrictions but preserves listed health, fire, building, noise, and other rules. |
| Sales tax / employer | No general county employer-tax layer was identified; any city-specific tax should be checked separately. | No general county employer-tax layer was identified. | Comptroller sales-tax registration when required; TWC unemployment-tax duties when liable; Texas new-hire reporting. |
First question: is your address actually inside a city?
A postal address is not a jurisdiction test. A property can use a familiar city name in its mailing address while sitting outside that city’s corporate limits. Montgomery County also has ETJs, special districts, utility districts, deed-restricted communities, and The Woodlands Township, so the boundary question can change who handles permits.
Start with the county’s GIS maps. If the parcel appears close to a municipal boundary, confirm the status with the municipality before submitting an application. This is especially important before signing a lease or paying for plans, because a city may require an allowed-use review, building permit, Certificate of Occupancy, sign approval, or other local process that the county does not issue in the same way.
Do not confuse an ETJ with city limits
An extraterritorial jurisdiction can give a city limited authority outside its corporate limits without making the property fully part of the city. The City of Conroe’s development materials, for example, distinguish work inside city limits from its joint-planning area. Ask the city and county which approvals apply to the specific parcel instead of treating “Conroe address” as the answer.
What Montgomery County actually handles
Land development and floodplain permitting
For unincorporated property, the county Permit Department is an important first stop. The county’s current page says updated floodplain regulations took effect October 1, 2025 and that a development permit is required for development on property unless an exemption is clearly stated in the regulations. The same page routes commercial permitting, residential permitting, subdivision review, consumer health, and mass gatherings.
Fire code
The Montgomery County Fire Marshal says the county adopted the 2024 International Fire Code with local amendments. The county fire code applies in all unincorporated parts of Montgomery County and, through interlocal arrangements, in the cities of Cut & Shoot, Magnolia, Montgomery, and Willis. The Fire Marshal lists review triggers including structures over 500 square feet, additions, interior build-outs that are part of a larger structure, and changes of use.
If your business is in another incorporated city, do not automatically send the fire portion to the county. Conroe, for example, has its own city building and fire process. The correct fire authority depends on the address.
Assumed names are a county-clerk function, not a license
The Montgomery County Clerk’s assumed-name page explains the split clearly. Depending on the entity type, an assumed name is filed either with the county clerk in each county where the business operates or with the Texas Secretary of State. Since September 1, 2019, the county clerk no longer accepts assumed-name filings for corporations, LLCs, limited partnerships, or foreign filing entities.
The clerk also warns that an Assumed Name Certificate is not a business license. That distinction matters. Filing “ABC Services” as a DBA does not answer whether the address is allowed for the use, whether a food permit is needed, or whether a professional license applies.
How the city layer changes the answer
Conroe: city building and occupancy rules come first for city sites
Inside Conroe city limits, the city handles its own building and occupancy process. The City of Conroe’s Certificate of Occupancy application says a building or structure cannot be used or occupied until the Building Official issues a CO. It also says a change in use or occupancy classification requires a commercial building permit rather than the basic CO application.
City of Montgomery: a good example of overlapping layers
The City of Montgomery Building & Permitting page lists city permits for commercial and residential work and new occupancy. It also states that all commercial projects, including occupant changes, must obtain a Montgomery County Fire Marshal permit and inspection, and that commercial food establishments must obtain a Montgomery County Environmental Health permit and inspection.
The Woodlands: not a normal city licensing model
The Woodlands Township is a special-purpose district, not a traditional incorporated city with a normal municipal building department. Its Covenant Administration program enforces residential and commercial covenants and standards, and permit applications are submitted through the Township’s Civic Access system.
Do not mistake a Township covenant approval for the only government approval. County fire, environmental health, state licensing, MUD or utility rules, and other agencies can still apply. Some properties in Grogan’s Forest are under dual authority involving the City of Shenandoah; the Township’s permitting-process page explains that special route.
Home businesses: city law, county rules, and private covenants can all matter
Texas changed the municipal home-business landscape in 2025. Local Government Code §229.902 says a municipality may not prohibit a qualifying “no-impact home-based business” or require that business or property owner to obtain a municipal license, permit, or other approval to operate. It also limits municipal rezoning requirements for home businesses.
The protection is not unlimited. The statute preserves municipal fire and building codes and rules relating to health, sanitation, traffic, waste, pollution, and noise, and it allows restrictions on certain activities such as other regulated activities sales. It also expressly does not stop enforcement of HOA rules, deed restrictions, or other private agreements.
That last point is important in Montgomery County. A home in The Woodlands may be subject to Township covenants even though The Woodlands is not a city. The Township says home businesses are allowed only under limited standards intended to keep the activity from changing the residential character. For other unincorporated subdivisions, read the deed restrictions as well as county rules.
Food businesses: separate fixed sites, mobile vendors, and temporary events
The Montgomery County Consumer Health page provides routes for opening a retail food establishment, initial inspections, temporary food events, farmers markets, health-permit renewals, and other food-establishment processes. Montgomery County Environmental Health also describes itself as a local agent for Texas DSHS.
Fixed restaurant or food establishment: confirm which health authority controls the exact location and use the current food-establishment application path. The City of Montgomery explicitly sends commercial food establishments to county Environmental Health. Other cities may have their own development, occupancy, fire, sign, or operating requirements in addition to the health layer.
Mobile food vendor: use the Texas DSHS Mobile Food Vendor page. Since July 1, 2026, the license is statewide. DSHS says local jurisdictions may still conduct inspections through agreements and mobile vendors must follow applicable state and local laws. A city may still regulate where the vehicle can operate, fire safety, events, or other matters that are not the replaced local health license.
Temporary booth or event: do not assume the statewide mobile-food vehicle license covers a stand or booth. DSHS defines the food vending vehicle separately, while the county Consumer Health page continues to provide a temporary-event permit route. Match the permit to how you actually sell.
Texas entity, tax, employer, and professional layers
Entity filing and assumed names
Texas does not have one general statewide business license. If you form a corporation, LLC, limited partnership, or another filing entity, use the Texas Secretary of State’s current business-filing system. As of September 29, 2026, SOSPortal replaced SOSDirect and SOSUpload for business filing, ordering, and searching. Do not treat entity formation as permission to operate at a particular Montgomery County address.
Sales and use tax
If you sell or lease taxable goods or provide taxable services, check the Texas Comptroller Online Tax Registration Application. The need for a sales-tax permit depends on what you sell and how you operate. A sales-tax permit is different from a county DBA, city occupancy approval, or professional license.
Hiring employees
If you hire, check the Texas Workforce Commission Unemployment Tax Program to determine whether and when you must establish an unemployment-tax account and file wage reports. Texas employers also have a separate new-hire reporting duty; the Attorney General says new hires and rehires generally must be reported within 20 calendar days after they start earning wages.
Professional and industry licensing
A county guide cannot replace the license for a regulated occupation. Contractors in licensed trades, child-care providers, health professionals, cosmetology businesses, vehicle dealers, other regulated activities sellers, and other regulated businesses should use the responsible Texas agency’s current licensing path. The state Business Permit Office and Texas Business Licenses & Permits Guide are useful starting points for finding the correct regulator.
Federal EIN
When an EIN is required, use the IRS EIN application. The IRS provides EINs directly at no charge. An EIN is a federal tax identifier; it is not a business license.
Common mistakes
- Searching only for “Montgomery County business license.” The county does not present one universal license, but that does not eliminate address- and activity-based permits.
- Assuming the mailing city controls the property. Confirm incorporated status and ETJ before applying.
- Calling a DBA a license. The County Clerk expressly says an Assumed Name Certificate is not a business license.
- Using an old mobile-food checklist. Local mobile-food licensing changed on July 1, 2026; the DSHS statewide license is now the starting point.
- Ignoring county fire jurisdiction inside a city. Cut & Shoot, Magnolia, Montgomery, and Willis use the county Fire Marshal fire-code route.
What to ask the city or county before you spend money
Phone or email script
“I plan to operate a [business type] at [exact street address]. Can you confirm whether this property is inside city limits or unincorporated Montgomery County, and which office controls land use, building/occupancy, fire review, and any activity-specific permit for this business? I will be [home-based / storefront / mobile / online], and I expect [customers / employees / food preparation / signs / deliveries] at the location. Please point me to the current application or portal for each approval that applies.”
Use the exact address and describe what happens at the property. “Online business” by itself is not enough if inventory, employees, customer visits, food, equipment, or commercial vehicles are also involved.

FAQ
Does Montgomery County, Texas require a general business license?
Montgomery County’s current business resources do not show one universal county business license for every business. Instead, county permits and filings depend on the address and activity, including development, fire, food, septic, assumed-name, and other rules.
How do I know whether my business is inside a city or in unincorporated Montgomery County?
Do not rely on the city name in a mailing address. Start with Montgomery County GIS, then confirm city-limit status with the municipality if the property is near a boundary or ETJ. The answer changes which office handles zoning, building, occupancy, signs, and other local permits.
Is The Woodlands an incorporated city for business-permit purposes?
No. The Woodlands Township is a special-purpose district and does not operate a traditional municipal building department. Township covenants and standards can still require Civic Access approvals, while Montgomery County, state agencies, special districts, and sometimes the City of Shenandoah control other requirements.
Where do I file a DBA in Montgomery County?
It depends on the entity. The County Clerk handles assumed names for applicable non-filing businesses, while corporations, LLCs, limited partnerships, and foreign filing entities use the Texas Secretary of State. A DBA is a name filing, not permission to operate.
Does a Montgomery County food truck need a county mobile-food license in 2026?
Start with Texas DSHS. Since July 1, 2026, qualifying mobile food vendors use the statewide DSHS license. Local governments can still have roles involving inspections, zoning, fire safety, events, and other local laws, so the state license does not erase every local requirement.
What should I check before running a business from home in Montgomery County?
Identify whether the home is inside a municipality, unincorporated county territory, or The Woodlands. Texas protects qualifying no-impact home businesses from certain municipal requirements, but health, fire, building, noise, county activity rules, and private HOA or deed restrictions can still matter.
