Why You Need a Water and Sewer Connection Permit
The San José Water and Sewer Connection Permit is required by law to ensure your restaurant's plumbing work meets city standards for safety, capacity, and environmental protection. The formal authorization is mandated by the City of San José Municipal Code Title 14, 'Wastewater Collection and Disposal,' which governs sanitary sewer connections, and the City's Standard Specifications and Details for Public Works Construction, which cover water main and lateral installation. These regulations are enforced by the City of San José's Environmental Services Department (for sewer) and the San José Water Company or the City's Public Works Department (for water, depending on location). Without this permit, any construction to connect your building to public water and sewer lines is illegal.
Failing to secure this permit before beginning plumbing work carries significant legal and financial penalties for your restaurant project. Based on enforcement actions in this jurisdiction, common consequences include:
- Daily Fines and Stop-Work Orders: The city can issue citations for work performed without a permit, halting all construction. Fines escalate for continued non-compliance.
- Service Disconnection and Project Stoppage: The city or utility provider can refuse to connect service or, for existing illegal connections, physically disconnect water and sewer lines, preventing your restaurant from opening or operating.
- Costly Remediation and Permit Revocation: You may be forced to tear out completed plumbing work for inspection, incurring thousands in rework costs. Your Certificate of Occupancy and other permits can be withheld until violations are corrected.
- Lease and Financing Defaults: Most commercial leases and construction loans require all permits to be in place. Non-compliance can trigger default clauses, risking your leasehold and funding.
Legal code: Local sewer use regulations, water connection requirements, road/sidewalk ordinances, grease discharge limits
Recent update: As of 2026, San José has integrated its water and sewer connection permit review into the city's electronic plan review portal for many commercial projects, though manual submission of physical site plans may still be required depending on the scope of work.
Who Needs a Water and Sewer Connection Permit?
| Type | Required | Notes |
|---|---|---|
| Restaurant (Full-Service) | Required | Required; connects potable water supply and sanitary sewer for kitchen, restrooms, and all fixtures, as mandated by San José Municipal Code § 13.06 and the Department of Public Works. |
| Bar / Nightclub | Required | Required; all establishments with plumbing fixtures serving the public (restrooms, bar sinks) must connect to the municipal water and sewer system, per San José Department of Public Works guidelines. |
| Food Truck | Not Required | Not required; mobile food facilities typically use temporary service connections or holding tanks and are regulated by the county health department, not the city's permanent connection permit. |
| Coffee Shop / Café | Required | Required; any food service business with sinks, dishwashers, espresso machines, and public restrooms needs permanent potable water and sewer connections, triggering the permit requirement. |

38 of 46 auto-filledProperty Address
addressEnter the complete physical street address of the restaurant, exactly as it appears on your lease or property deed, including suite or unit number if applicable.
COMMON MISTAKE: Using a P.O. Box or mailing address instead of the physical property address, which the San Jose Environmental Services Department requires for a valid service location.
Tax Parcel Number
textEnter the 9- or 10-digit Assessor's Parcel Number (APN) assigned by the Santa Clara County Assessor's Office, which uniquely identifies your property.
COMMON MISTAKE: Entering a lot number from a subdivision plan or a business license number, which are not valid APNs and will cause the application to be rejected for incorrect property identification.
Lot Size (sq ft)
numberEnter the total land area of your property in square feet, found on your property's plat map, deed, or the Santa Clara County Assessor's website.
COMMON MISTAKE: Calculating only the building footprint or an estimate; the San Jose Environmental Services Department cross-references this with county records, and a mismatch can delay review.
Property Owner Name
textEnter the full legal name of the property owner(s) or the legal entity (e.g., an LLC) that holds title to the property, as recorded with the county.
COMMON MISTAKE: Listing a property management company or a tenant's name instead of the legal owner, which invalidates the application's authorization requirement.
Owner Authorization Obtained
booleanCheck 'Yes' only if you have a signed letter from the property owner authorizing you to apply for this utility connection permit on their behalf.
COMMON MISTAKE: Checking 'Yes' without the actual signed authorization letter attached, which is an immediate grounds for rejection by San Jose Environmental Services.
Authorization Letter
documentUpload a signed letter from the property owner (or authorized agent) on company letterhead, explicitly granting permission to apply for the water and sewer connection.
COMMON MISTAKE: Submitting an unsigned letter, a lease agreement in place of a specific authorization letter, or a document that does not list the exact permit type, any of which will be rejected.
Business Legal Name
textEnter the exact legal name of your business as it is registered with the California Secretary of State or your local Fictitious Business Name filing.
COMMON MISTAKE: Using a 'doing business as' (DBA) name that is not officially registered, which creates a mismatch with other city permits and triggers a correction request.
Business Type
textEnter the type of entity, such as 'Corporation,' 'Limited Liability Company (LLC),' 'Sole Proprietorship,' or 'Partnership.'
COMMON MISTAKE: Entering the type of cuisine or service (e.g., 'restaurant') instead of the legal entity structure, which is needed for the city's billing and legal records.
Food Service Business
booleanCheck 'Yes' if your business will prepare, serve, or sell food or beverages; this determines the water meter size and sewer service charges.
COMMON MISTAKE: Incorrectly marking 'No' for a coffee shop or bakery, which leads to an undersized meter assignment and requires a costly permit amendment after installation.
Contact Name
textEnter the full name of the primary point of contact for this application, who must be authorized to make decisions and receive communications from the city.
COMMON MISTAKE: Listing a generic title like 'Manager' without a specific person's name, which delays communication and can hold up inspections and approvals.

Top 5 Water and Sewer Connection Permit Mistakes
1. Incorrectly Calculating Total Fixture Units
Entering a unit count based on a rough guess or an outdated plumbing code. The San Jose Department of Public Works (DPW) calculates permit fees based on the accurate total fixture unit count. A calculation error is often not caught until plan review, adding 2-3 weeks for corrections and resubmission. Avoid this by having your plumber or contractor provide the count using the Uniform Plumbing Code (UPC) standards required by San Jose, not a general estimate.
2. Submitting Unsealed Site & Building Plans
Attaching preliminary sketches or plans without a California-licensed civil engineer or architect's professional stamp. San Jose DPW mandates sealed drawings showing the exact location, depth, and size of the proposed connection relative to property lines and existing utilities. Unsealed plans are rejected outright, causing a 1-2 week delay. Ensure your contractor submits the final, stamped construction drawings specifically for this permit application, not conceptual layouts.
3. Omitting the Proof of Water Rights or Service Area Verification
Assuming the application is complete without documentation proving you are in the San Jose Municipal Water System service area or have legal rights to connect. The DPW requires this verification to process your application. Missing this document triggers a request for information (RFI), halting review for 10-15 business days. Contact the San Jose Municipal Water System customer service line prior to applying to obtain a formal service area confirmation letter for your exact address.

Prepare Site Plan and Pre-Application Documents
Hire a licensed civil engineer to create a site plan detailing your proposed water and sewer connections, including tie-in points, pipe sizes, and routing. This plan must be stamped and signed. Simultaneously, apply for your City of San Jose Business Tax Certificate and have your project’s building permit application number ready. Missing the engineered site plan is the most common reason for immediate application rejection.
Submit Application and Fees to San Jose Municipal Water System
File your completed Water & Sewer Connection Permit Application (Form SJW-100) with all attachments through the San Jose Municipal Water System (SJMWS) online portal or at their Development Services counter. You must submit the stamped site plan, business tax certificate, and the completed application. The government filing fee for processing and plan check is typically $2,000–$8,000, depending on project scope and meter size, and must be paid at submission.
Plan Check and SJMWS Technical Review
SJMWS engineers review your application packet for compliance with the City of San Jose Municipal Code, Title 16, and current water system standards. They will check pipe sizing, pressure requirements, and backflow prevention details. Expect a request for additional information (RAI) if plans are unclear or non-compliant; responding to an RAI is the primary cause of timeline delays. This review is separate from the city’s building permit review.

See All RequirementsThe processing timeline for this permit varies significantly based on project complexity and coordination with other reviews. Per the San Jose Department of Public Works application guide, typical timelines range from several weeks for straightforward connections to several months if plans require extensive revisions or are part of a larger Building Permit project. Contact the Department of Public Works to confirm current review queue times before finalizing your construction schedule.
The government filing fee for the initial application is listed as $0–$0, per the San Jose Department of Public Works fee schedule. However, this does not include required system development charges, plan review fees, inspection fees, or Backflow Prevention Device Certification costs, which can total several thousand dollars depending on pipe size and location. Not legal advice — verify the full, final cost estimate with the San Jose Department of Public Works.
No, these permits are non-transferable. A Water and Sewer Connection Permit is issued for a specific property address and legal parcel, as stated in San Jose Municipal Code regulations. If you move your restaurant, you must apply for a new permit at the new location, which requires submitting all site plans and paying applicable fees again.
This permit does not require periodic renewal. Once the connection is installed, inspected, and approved by the San Jose Department of Public Works, the permit is considered finalized and closed. Ongoing compliance typically involves annual requirements like maintaining a backflow prevention device, but the connection permit itself is a one-time approval for the physical installation.
A city inspector verifies the installation complies with approved plans, the San Jose Municipal Code, and the California Plumbing Code. They will check pipe materials, sizing, depth, slope, joint integrity, and proper separation from other utilities before the trench is backfilled. Failing inspection for incorrect materials or improper slope can add 2–3 weeks to your timeline for rework and a re-inspection fee.
