City of Modesto business license

Modesto lists three Business License types: commercial, home, and outside. Use the city’s online application or its applications and agreements page, which also provides the mailed application, Home Business Agreement, and stormwater form.

Commercial business

Use this path for a storefront, office, shop, studio, warehouse, restaurant, salon, gym, or another non-home location. Check zoning, building use, signs, parking, fire issues, and tenant improvements before signing a lease.

Home business

The Home Business Agreement must accompany the home-business application. The current form asks about customer activity, a business vehicle, large family day care, and cottage food. Special activities can have rules beyond the ordinary home-business limits.

Outside business

Use this path if the business is based outside Modesto but performs services inside the city, such as contracting, cleaning, repair, consulting, or mobile services.

Costs you can plan for

Modesto costs depend on license type, start month, reporting cycle, gross receipts, and location. Use the city’s fees, taxes, and deadlines page before paying.

Do not use an old screenshot, blog post, or saved PDF as your final fee source. Use the official payment or fee page before you submit money.

Stanislaus County requirements that may apply

The county is important for fictitious business names, Environmental Health permits, and local licensing outside incorporated cities. A Modesto business does not automatically need a separate county business license.

Fictitious business name

File a Fictitious Business Name Statement with the Stanislaus County Clerk-Recorder when the rules apply. The county does not reserve duplicate names. Publication must begin within 45 days after filing and run once a week for four successive weeks; proof of publication must then be filed. Statements generally expire after five years unless a change triggers earlier refiling.

Food and mobile food

The county Food Program covers retail food facilities, cottage food, mobile food, temporary food facilities, and farmers’ markets. Its forms page provides food-facility, cottage-food, temporary-event, and mobile-food forms and currently says they cannot be electronically filed.

Stanislaus County currently does not allow Microenterprise Home Kitchen Operations under the AB 626 framework. The 2026 Environmental Resources fee schedule, effective June 18, 2026, lists current food and mobile-food fees by category.

County business license outside city limits

If the location is outside Modesto city limits, use the county business license page. County renewals apply to locations outside city limits; a Modesto location follows the city route.

California state registrations and permits

State filings are separate from the Modesto license. Common checks include entity filings, seller’s permits, employer accounts, state taxes, and industry licenses.

Secretary of State filings

LLCs, corporations, and other registered entities can start with the Secretary of State’s Business Entities information and bizfile Online. Effective August 1, 2026, the Secretary of State requires web User Access for Statement of Information filings and for users conducting online filings in bizfile.

Seller’s permit

CDTFA says a seller’s permit is required if you are engaged in business in California and intend to sell or lease tangible personal property normally subject to sales tax. Use the official seller’s permit guidance. It does not replace Modesto’s Business License. See our seller’s permit vs business license guide.

If you hire employees

EDD says a business must register as an employer within 15 days after hiring employees and paying more than $100 in wages in a calendar quarter. Employers must also report new or rehired employees to the New Employee Registry within 20 calendar days of the start-of-work date. EDD updated e-Services for Business security and navigation in May 2026; the registration threshold itself did not change.

State tax and industry licenses

FTB says an LLC doing business or organized in California generally owes the $800 annual LLC tax, subject to specific exceptions. Use the current FTB LLC page. For regulated work, use the CSLB, DCA License Search, ABC, or Department of Cannabis Control as applicable. CalGOLD can help identify permit contacts.

For broader state steps, see our California business license guide.

Federal steps that may apply

There is no general federal business license for an ordinary Modesto business. Get an EIN directly through the IRS when your tax, payroll, entity, or banking situation requires one. The IRS does not charge for the application.

Federal permits are activity-based; the SBA guide routes regulated activities to the responsible federal agencies.

FinCEN’s current BOI rule exempts U.S.-created companies from BOI reporting. An August 11, 2026 final rule confirmed that framework rather than newly creating the domestic-company exemption. Certain foreign companies registered in the United States can still have duties; use FinCEN’s current BOI quick reference.

Zoning, home, building, fire, signs, and special permits

A Business License does not approve every address, sign, food setup, cart, building change, or sidewalk use. Check property and activity rules before spending money.

Zoning and property use

Use City Planning & Zoning and the city mapping tools to check the zoning district, allowed use, and city-limit status. A mailing address that says “Modesto” does not by itself prove the property is inside city limits.

Building and tenant improvements

For walls, plumbing, electrical or mechanical work, exits, accessibility, signs, grease equipment, or a change of use, check Building Permits before work starts. Modesto adopted the 2025 California Building, Plumbing, Electrical, Mechanical, and Existing Building Codes in 2026; the building-code ordinance took effect June 11.

The current Building Safety fee schedule is effective July 1, 2026 through June 30, 2027. Modesto’s 2025 California Fire Code was adopted before this review window and became effective in January 2026.

Food, mobile food, and sidewalk vending

Modesto’s Mobile Food Facility route requires a valid city Business License, a restroom agreement within 200 feet, and a Stanislaus County Environmental Resources health permit before operation. The county forms page provides mobile-food permit, plan-review, commissary, and restroom-letter forms. Sidewalk vending and temporary events can use different routes.

Our food truck guide and cottage food guide can help organize questions, but current government forms control.

Signs and special activity

Modesto says signs generally require a permit. Entertainment, tents, propane, open flame, outdoor dining, sidewalk vending, public-way use, and special events can add Planning, Building Safety, Fire, Code Enforcement, Engineering, or other review depending on the activity.

Real-world examples

Home-based online seller

A Modesto resident selling handmade goods from home may need the home Business License, Home Business Agreement, and stormwater form. Taxable goods can trigger a CDTFA seller’s permit, and a trade name can trigger the county FBN route. See our online business license guide.

Downtown retail shop

Check zoning and allowed use before signing the lease, then the commercial Business License, building or sign permits, seller’s permit, and gross-receipts reporting. A Downtown Improvement District address can add DID tax.

Food truck or cart

A mobile food operator may need Modesto business and location approvals plus Stanislaus County food-health permits and forms. Restroom documentation, seller’s-permit duties, heat or fuel, and temporary-event work can add more steps.

Contractor based outside Modesto

A contractor based outside Modesto but working inside the city may need an outside Business License. CSLB licensing, job-specific building permits, and city gross-receipts reporting remain separate layers.

What to do if this doesn’t work

If the application is confusing, start with Modesto Business Licensing and identify the commercial, home, or outside route. If zoning or building use is the problem, stop before spending more money and ask Planning what approval the site needs.

If the address is outside Modesto city limits, use the Stanislaus County local-license route. For regulated work, go to the controlling agency: Environmental Resources for many food permits, CSLB for contractors, ABC for alcohol, DCA boards for many professions, and the Department of Cannabis Control for cannabis licensing.
