Water and Sewer Connection Permit in San Diego, California (2026)
Without a Water and Sewer Connection Permit from the San Diego Water Department, you cannot legally connect your restaurant's water supply or wastewater lines to the municipal system—meaning no running water, no plumbing, and no certificate of occupancy. This permit (also called a water service connection agreement or sewer lateral authorization) certifies that your facility meets San Diego's plumbing codes and infrastructure standards. Key facts:

Why You Need a Water and Sewer Connection Permit
To legally connect your commercial kitchen to the City of San Diego's public water and sewer systems, you must obtain a Water and Sewer Connection Permit. This is mandated by San Diego Municipal Code, Division 4: Health and Sanitation, specifically under sewer use regulations (Chapters 6.7, 6.8) and water connection requirements governed by the city's Public Utilities Department. The permit ensures your proposed fixtures, flow rates, and discharge (especially grease from cooking operations) comply with local standards and protect the municipal infrastructure. Without this permit, you cannot have potable water or wastewater service turned on at your business address.
Operating a restaurant without this permit puts you at immediate risk of enforcement actions by the city's Development Services and Public Utilities departments. Based on ApronPrep's analysis of code enforcement in San Diego, the primary consequences include:
- Service disconnection: The city can terminate your water and sewer service, forcing an immediate business shutdown.
- Substantial fines: Violations typically accrue daily penalties until compliance is achieved, often starting at hundreds of dollars per day.
- Required remediation: You may be forced to halt construction or modify completed plumbing work at your own expense to meet code.
- Lease and insurance complications Landlords often require proof of permitted utility connections, and operating without this permit can void property insurance coverage for water or sewer-related damage.
Legal code: Local sewer use regulations, water connection requirements, road/sidewalk ordinances, grease discharge limits
Recent update: As of 2026, San Diego has integrated this permit application more fully into its online Development Services portal, requiring digital submission of plumbing plans for most commercial projects.
Who Needs a Water and Sewer Connection Permit?
| Type | Required | Notes |
|---|---|---|
| Restaurant (Full-Service) | Required | Required for all new or modified connections to the city's public water and sewer mains, as your kitchen, bar sinks, and restrooms will generate significant wastewater. |
| Bar / Nightclub | Required | Required because bar sinks, ice machines, and restroom facilities must connect to the municipal sewer system per San Diego Municipal Code §63.0104. |
| Food Truck | Not Required | Typically exempt from this specific permit, as food trucks are serviced by a commissary's existing water/sewer connections and use a holding tank for gray water. |
| Coffee Shop / Café | Required | Required due to the installation of espresso machines, commercial dishwashers, and restroom sinks that discharge into the public sewer system. |

27 of 32 auto-filledProperty Address for Water/Sewer Connection
textEnter the complete, physical 'service address' of the restaurant property where water and sewer lines will be connected, exactly as it appears on your lease or deed, including unit or suite number if applicable.
COMMON MISTAKE: Entering a mailing address, P.O. Box, or a neighboring business address instead of the exact physical service location, which causes the Public Utilities Department to reject the application as incomplete.
Assessor's Parcel Number (APN)
textEnter the 10-digit Assessor's Parcel Number (APN) assigned to the property by the San Diego County Assessor's Office, formatted as XXX-XXX-XX-00.
COMMON MISTAKE: Using an old or incorrect APN from a preliminary title report, or entering the number with dashes in the wrong places, which fails the city's property verification check and halts review.
Property Owner Full Legal Name
textEnter the full legal name of the property owner as it appears on the most recent recorded deed, whether an individual (First Middle Last) or a business entity (e.g., 'XYZ Properties, LLC').
COMMON MISTAKE: Listing a tenant, property manager, or a DBA (Doing Business As) name instead of the legal property owner, which creates a mismatch with county records and requires a notarized authorization letter.
Is Property Owner the Applicant?
checkboxCheck this box only if the legal property owner listed above is the same party submitting this permit application; if a tenant is applying, leave it unchecked.
COMMON MISTAKE: Incorrectly checking the box when a tenant is applying, which triggers an automatic denial because the required tenant authorization forms are not submitted with the application.
Proof of Property Ownership (Deed/Title)
textList the specific document you are attaching as proof, such as a 'Grant Deed,' 'Preliminary Title Report,' or 'Quitclaim Deed,' including the recording date or document number.
COMMON MISTAKE: Writing 'See attached' or leaving this field blank, which results in an immediate 'Incomplete Application' notice because reviewers cannot confirm the referenced document without a clear description in the form.
Has Existing Utility Account?
checkboxCheck this box only if there is an active, open water/sewer utility account in the property owner's name at this address; for a new construction or a property that has been vacant, leave it unchecked.
COMMON MISTAKE: Checking 'Yes' for a new construction site, which causes the city to search for a non-existent account and delay the application for 5–7 business days while the discrepancy is resolved.
Utility Account Number
textIf you checked 'Yes' for an existing account, enter the full 9-digit account number from a recent City of San Diego Public Utilities bill; if 'No,' write 'N/A' or 'New Connection.'
COMMON MISTAKE: Leaving this field blank when 'No' is checked, which often causes a reviewer to place the application on hold for clarification, adding 3–5 days to the timeline.
Owner Mailing Address
textEnter the complete mailing address where official correspondence and utility bills should be sent for the property owner, which can be different from the physical property address.
COMMON MISTAKE: Repeating the property address here if the owner receives mail elsewhere, which can lead to important inspection notices or bills being sent to the wrong location and causing compliance delays.
Owner Phone Number
textEnter a direct, daytime phone number for the property owner or an authorized representative who can answer questions about ownership and the application.
COMMON MISTAKE: Providing a disconnected number or a phone number for a tenant/property manager without authorization, which can stall the application if the city needs immediate verification.
Owner Email Address
textEnter a valid, regularly monitored email address for the property owner to receive digital notifications, application status updates, and electronic invoices from the Public Utilities Department.
COMMON MISTAKE: Using an email address that frequently hits its inbox limit or is associated with a former property manager, causing critical digital communications to bounce back and be missed.

Top 5 Water and Sewer Connection Permit Mistakes
1. Using Inaccurate or Outdated Water/Sewer Tap Details
Entering estimated tap sizes or the wrong existing main locations (e.g., stating a 6-inch main when it's 4-inch) triggers a mandatory field inspection by Public Utilities staff to verify before plan review can proceed. Based on ApronPrep's analysis, this mismatch is the most common cause of initial rejection, adding 2–4 weeks to your timeline as the city schedules a verification visit. Avoid this by submitting a request for underground service records with the Public Utilities Department or hiring a civil engineer to perform a site locator survey before you apply.
2. Missing the Property Owner’s Signature on the Permit Application
If the applicant is a contractor or tenant but the legal property owner hasn't signed the 'Owner Authorization' section, the application is administratively incomplete and will not be accepted for processing. This oversight adds a minimum 3-5 business day delay for mail-back or in-person re-submission. Always verify the application's signature block matches the recorded owner on file with the San Diego County Assessor – a tenant cannot sign for the owner without a notarized authorization letter on file with the department.
3. Submitting Incomplete Site and Utility Plans
Providing conceptual sketches instead of scaled, engineer-stamped site plans that show all proposed trenches, pipe materials (e.g., specifying PVC versus ductile iron), depths, and cleanout locations leads to an immediate 'plans incomplete' rejection. This mistake requires full re-drafting and resubmission, setting you back 1-2 weeks minimum. Ensure your plans meet the city’s 'Standard Specifications for Public Works Construction' and clearly dimension the connection point from the property line to the city main.

Obtain and complete the water and sewer connection permit application form from San Diego Water Department
Download the Water and Sewer Connection Permit application (Form WD-1) from the San Diego Water Department website or pick up a hard copy at their office at 9192 Topaz Street. The form has 28 fields including property address, meter size, connection type, and contractor information. Most applicants complete this in 20–30 minutes with basic business and property details on hand.
Prepare site plan and engineering drawings showing proposed connection locations
Have a licensed engineer or plumber prepare a scaled site plan (minimum 1 inch = 40 feet) showing the restaurant location, existing water/sewer mains, proposed connection points, and pipe routing. San Diego requires these drawings to meet California Title 24 standards. This step is the #1 cause of permit delays — incomplete or non-compliant drawings trigger a 3–4 week revision cycle.
Gather proof of property ownership and authorization documents
Collect a copy of the current property deed or lease agreement, and if you are not the property owner, provide a notarized Letter of Authorization from the owner permitting you to apply for water/sewer connections. San Diego Water Department requires this to verify legal standing. Keep originals for your records — copies are filed with the permit.

See All RequirementsTimeline varies depending on the complexity of your project and whether your application is complete on first submission, per the San Diego Public Utilities Department. Simple connections with straightforward site conditions may take 2–4 weeks, while projects requiring engineering review, environmental assessment, or infrastructure upgrades can extend to 8–12 weeks or longer. Contact the San Diego Public Utilities Department at (619) 692-5600 or visit their website to confirm current processing times for your specific project type.
San Diego does not charge a separate government filing fee for water and sewer connection permits, but you will typically incur costs for required engineering studies, site surveys, and connection labor performed by licensed contractors—amounts vary by project scope and location. Additionally, you may need to pay San Diego Public Utilities Department fees for capacity availability studies or system development charges if new infrastructure is required. Contact the San Diego Public Utilities Department to confirm all applicable costs for your specific connection project. Not legal advice—verify current fees with the department before budgeting.
No, water and sewer connection permits are location-specific and cannot be transferred to a new address. If you relocate your restaurant, you will need to apply for a new water and sewer connection permit at the new location, which may require a separate application and inspection. You should also coordinate with your Building Permit application if renovations or new infrastructure are involved at the new site.
Water and sewer connection permits do not require periodic renewal once approved and the connection is operational, per San Diego Public Utilities Department practice. However, if you modify your connection (e.g., increase water demand, add grease traps, or reconfigure your wastewater system), you must notify the department and may need to submit an amended permit application. Contact the San Diego Public Utilities Department to confirm whether changes to your operations trigger a new or modified permit requirement.
During the inspection, San Diego Public Utilities Department staff will verify that all installed piping, meters, backflow prevention devices, and connections comply with the California Plumbing Code and municipal standards. The inspector will also confirm that grease traps, interceptors, and other treatment systems (if required) are properly sized and installed. If deficiencies are found, you will receive a correction notice; once corrected and re-inspected, your connection will be approved for operation. Ensure your licensed plumber is familiar with Backflow Prevention Device Certification requirements, as backflow preventers are often a critical inspection point.
