Water and Sewer Connection Permit in Los Angeles, California (2026)
Without a Water and Sewer Connection Permit from the Los Angeles Department of Water and Power (LADWP), you cannot legally connect your restaurant to the city's water and sewer infrastructure — meaning no water supply, no drainage, and no path to opening. The Water and Sewer Connection Permit (also called a utility connection authorization or water service application) is issued by the LADWP and confirms that your property meets the city's water infrastructure and plumbing standards.

Why You Need a Water and Sewer Connection Permit
Operating a restaurant in Los Angeles without a Water and Sewer Connection Permit puts your entire operation at legal risk before you serve a single customer. The City of Los Angeles requires this permit under the Los Angeles Municipal Code (LAMC), which governs sewer use and wastewater discharge (see LAMC Title 6, Chapter 6), water service connections (LAMC Title 5), and street or sidewalk excavations required to run utility lines (LAMC Title 6, Article 4). For restaurants specifically, the Los Angeles Bureau of Sanitation also enforces grease discharge limits under the City's Fats, Oils, and Grease (FOG) Control Program — meaning your connection permit ties directly to grease interceptor installation and compliance. The issuing authorities are the Los Angeles Department of Public Works (Bureau of Engineering for sewer connections) and the Los Angeles Department of Water and Power (LADWP) for water service connections. Verify current code requirements directly on the Bureau of Engineering's official permit portal or the LAMC online code library, as section-level citations can change with amendments.
Skipping or delaying this permit creates cascading consequences that can freeze your opening timeline and expose you to ongoing liability. Consequences include:
- Service disconnection — LADWP and the Bureau of Sanitation have authority to physically cut water and sewer service to non-compliant properties, shutting down operations immediately
- Daily fines — unpermitted connections and FOG violations can trigger per-day penalty assessments under LAMC; specific fine amounts are set by ordinance and should be confirmed with the Bureau of Sanitation directly, as they are subject to annual adjustment
- Required remediation at owner's expense — if an unpermitted connection is discovered, the city can mandate excavation, inspection, and re-connection at the property owner's or tenant's cost, which often runs far higher than the original permit fees
- Permit revocation and health code holds — the Los Angeles County Department of Public Health can place a hold on your food facility permit if utility compliance is unresolved, blocking your Certificate of Occupancy
- Insurance and lease implications — most commercial leases require tenants to maintain all required municipal permits; an unpermitted connection can constitute a lease default, and general liability insurers may deny claims arising from unpermitted utility work
Not legal advice — verify current penalty schedules and code sections with the Los Angeles Bureau of Engineering and Bureau of Sanitation before submitting your application.
Legal code: Local sewer use regulations, water connection requirements, road/sidewalk ordinances, grease discharge limits
Recent update: As of 2025, the Los Angeles Bureau of Engineering updated its online permit application portal to accept digital submissions for sewer connection permits, reducing the need for in-person filing at the Public Works counter — contact the Bureau directly to confirm whether your specific connection type qualifies for electronic processing.
Who Needs a Water and Sewer Connection Permit?
| Type | Required | Notes |
|---|---|---|
| Restaurant (Full-Service) | Required | Any full-service restaurant establishing or modifying a permanent connection to the Los Angeles municipal water or sewer system must obtain a Water and Sewer Connection Permit from the LA Department of Public Works, Bureau of Engineering, per Los Angeles Municipal Code § 64.10. |
| Bar / Nightclub | Required | Bars and nightclubs that serve beverages and have restroom facilities require a permanent sewer connection, triggering the permit requirement under LAMC § 64.10, regardless of whether food service is the primary offering. |
| Food Truck | Not Required | Food trucks operate from a mobile vehicle and do not establish a permanent connection to the municipal water or sewer infrastructure; they are instead required to obtain wastewater disposal approval through an approved commissary, per LA County Department of Public Health regulations — a separate process from the Bureau of Engineering connection permit. |
| Coffee Shop / Café | Required | Coffee shops and cafés with fixed locations require a permanent water supply and sewer discharge connection for espresso equipment, sinks, and restrooms, making the Water and Sewer Connection Permit mandatory under LAMC § 64.10. |

42 of 51 auto-filledProperty Address
addressEnter the full street address of the property requiring water and sewer connection, including street number, street name, city, state, and ZIP code — this must match the address on your building permit exactly.
COMMON MISTAKE: Entering a mailing address or P.O. Box instead of the physical property address will trigger an automatic rejection, as LADWP and the Bureau of Sanitation require a verifiable street location for field inspection routing.
Parcel/APN Number
textEnter the Los Angeles County Assessor's Parcel Number (APN) in the standard format: four digits, dash, three digits, dash, three digits (e.g., 5123-456-789) — find this on your property tax bill, grant deed, or the LA County Assessor's portal at assessor.lacounty.gov.
COMMON MISTAKE: Transposing digits or omitting dashes causes a parcel lookup failure in LADWP's GIS system, resulting in a hold on your application until the correct APN is resubmitted.
Zoning Classification
textEnter the official zoning designation assigned to the parcel by the Los Angeles Department of City Planning (e.g., C2, R4, M1) — verify the current classification at the ZIMAS portal (zimas.lacity.org) rather than relying on your lease or prior permits.
COMMON MISTAKE: Using an outdated or assumed zoning code instead of the ZIMAS-confirmed designation can cause a mismatch with the Bureau of Sanitation's allowable use tables, delaying approval by 2–4 weeks.
Property Owner Name
textEnter the legal name of the property owner exactly as it appears on the recorded grant deed — for LLCs or corporations, enter the full registered entity name, not a DBA or individual representative's name.
COMMON MISTAKE: Using a shortened business name or an individual's name when the property is held by an LLC will cause a title mismatch that flags the application for additional verification.
Property Owner Phone
textEnter a direct daytime phone number for the property owner in the format (XXX) XXX-XXXX — LADWP and the Bureau of Sanitation use this number to schedule on-site connection inspections and cannot proceed without a reachable contact.
COMMON MISTAKE: Providing a general office or answering service number that cannot confirm inspection appointments often causes scheduling failures that delay issuance by 1–2 weeks.
Property Owner Email
textEnter a valid email address for the property owner where official permit notices and inspection confirmations will be sent — ensure the inbox is actively monitored, as missed notices can result in application expiration.
COMMON MISTAKE: Entering a typo in the email domain (e.g., '.con' instead of '.com') means all official correspondence goes undelivered, and applicants often don't discover the error until they check on a stalled application.
Applicant is Property Owner
booleanSelect 'Yes' if the person submitting this application is also the recorded property owner; select 'No' if you are a tenant, contractor, or authorized agent — your answer to this field determines whether the Owner Authorization Letter (field owner_authorization) is required.
COMMON MISTAKE: Selecting 'Yes' when the applicant is a licensed contractor or tenant — rather than the deed-holding owner — causes a document inconsistency that triggers a rejection request for the missing authorization letter.
Owner Authorization Letter
documentUpload a signed letter from the recorded property owner explicitly authorizing the applicant to apply for and receive a Water and Sewer Connection Permit on their behalf — the letter must include the property address, APN, owner's printed name, signature, and date.
COMMON MISTAKE: Submitting an undated letter or a letter that references a different permit type or property address will result in rejection; the Bureau of Sanitation requires the authorization to match the exact scope of this application.
Business Type/Use
textEnter the specific intended use of the property (e.g., 'Full-Service Restaurant,' 'Fast Food Restaurant,' 'Food Truck Commissary') — the Bureau of Sanitation uses this to calculate estimated wastewater discharge capacity and assign the correct connection fee tier.
COMMON MISTAKE: Entering a generic description like 'Food Service' or 'Commercial' instead of the specific restaurant type can result in an incorrect capacity assessment, requiring a corrective resubmission and adding 2–3 weeks to processing.
Active Building Permit
booleanSelect 'Yes' only if a current, active building permit has been issued by the Los Angeles Department of Building and Safety (LADBS) for this property — you will be required to provide the permit number, and LADWP cross-references it in the LADBS permit database before approving the connection.
COMMON MISTAKE: Selecting 'Yes' based on a permit application that has not yet been issued, or referencing an expired permit number, will result in a database mismatch and immediate hold on the connection permit.

Top 5 Water and Sewer Connection Permit Mistakes
1. Submitting an Incomplete or Outdated Site Plan
Based on ApronPrep's analysis of Water and Sewer Connection Permit applications in Los Angeles, the single most common rejection trigger is a site plan that omits required utility layout details — such as the precise location of the proposed connection point, pipe diameter, and distance from the public main. The LA Bureau of Engineering will return the application outright if the site plan doesn't match the address on record or uses an outdated property boundary. Use a licensed civil engineer's stamped drawing dated within 12 months of submission; a hand-sketched or Google Maps printout will not be accepted and adds 3–4 weeks to your timeline while you resubmit.
2. Using the Wrong Connection Size or Service Classification
Applicants frequently select a residential ¾-inch water service size on the form when a commercial food service operation legally requires a 1-inch or larger meter — a mismatch the Bureau of Engineering flags during plan check. For a restaurant, the meter size must reflect peak flow demand calculations based on fixture units; entering the wrong size means plan check fails and the permit fee calculation is void, requiring a corrected application. Before submitting, confirm your required meter size with a licensed plumber using the LA Department of Water and Power's (LADWP) meter sizing guide, and make sure the classification on the permit form reads 'Commercial' rather than 'Residential.'
3. Paying the Wrong Government Filing Fee or Skipping the LADWP Clearance Step
Water and Sewer Connection Permit fees in Los Angeles are calculated by connection size, service type, and whether a new lateral or tie-in to an existing main is required — they are not a flat rate, and submitting the wrong payment amount causes the Bureau of Engineering to place the application on hold. A common scenario: an applicant pays the standard plan check deposit but omits the separate sewer capacity charge assessed by LA Sanitation (LASAN), which can run several thousand dollars depending on the equivalent dwelling unit (EDU) calculation for the restaurant. Verify the full fee breakdown — including LADWP service connection fees and LASAN capacity charges — before submitting, and obtain written confirmation of the total owed from each issuing authority.

Gather Property and Ownership Documentation
Collect your property deed, title report, and proof of ownership (recorded grant deed or title insurance commitment). You'll also need your restaurant's business license, EIN letter, and a letter from your landlord authorizing the connection work if you're leasing. The Los Angeles Department of Water and Power (LADWP) requires all ownership documents to be no more than 6 months old. Missing or outdated ownership proof is the #1 cause of application rejection — plan 1–2 weeks to obtain a current title report if you don't have one.
Prepare Site Plans and Plumbing Drawings
Hire a licensed plumber or civil engineer to prepare a site plan showing your restaurant's location, existing sewer/water lines, and proposed connection points. The plan must include lot dimensions, building footprint, and distance measurements to the nearest public water and sewer mains — LADWP requires these dimensions to be within 1 foot of actual measurements. Include drainage calculations if your restaurant will handle grease or high-volume wastewater. This step typically takes 2–4 weeks depending on your engineer's availability and site complexity.
Submit Application to LADWP Online Portal or In-Person
File your application through LADWP's online Development Services portal (ladwp.com/developer) or submit in-person at the LADWP Development Services office (111 N. Hope St., Los Angeles, CA 90012). Include the completed application form, site plan, plumbing drawings, property deed, business license, and a check or credit card payment for government filing fees (typically $500–$2,500 depending on connection type and property size — contact LADWP to confirm current fees for your specific project). Online submissions typically process faster than in-person filings. Keep a copy of your submitted application and confirmation number for your records.

See All RequirementsTimeline varies depending on whether your location requires new infrastructure or can connect to existing lines, per the Los Angeles Department of Water and Power (LADWP) and LA Sanitation & Environment (LASAN) application guides. Initial review and site assessment typically take 2–4 weeks, but if construction or design modifications are needed, the full process can extend to 8–12 weeks or longer. Contact LADWP and LASAN directly to confirm current processing times for your specific project scope.
Government filing fees for water and sewer connection permits in Los Angeles are $0–$0; however, you will incur separate costs for required design work, engineering plans, and connection fees charged by LADWP and LASAN. Connection and capacity charges can range significantly based on meter size and proximity to existing infrastructure — contact LADWP at (800) 342-5397 and LASAN to request a formal cost estimate for your project. Not legal advice — verify all fees with the respective authorities.
No — water and sewer connection permits are location-specific and cannot be transferred to a different address. If you relocate your restaurant, you must apply for a new water and sewer connection permit at the new location, and you may also need to obtain a Building Permit for any required plumbing work. Contact LADWP and LASAN early in your relocation planning to understand timeline and infrastructure requirements at the new site.
Water and sewer connection permits do not require renewal — once your connection is activated and inspected, the permit remains valid as long as the service address and account remain active with LADWP and LASAN. You must maintain continuous service and comply with all water and sewer usage regulations; if service is interrupted for more than a specified period (typically 12 months per LADWP policy), you may need to reapply. Contact LADWP customer service to confirm renewal requirements if your service has been inactive.
The inspection verifies that all plumbing connections meet Los Angeles Building Code standards and that your backflow prevention devices are properly installed and certified. Inspectors from LADWP and/or LASAN will check meter placement, line pressurization, and compliance with the Backflow Prevention Device Certification requirements. If deficiencies are found, you must correct them and schedule a re-inspection; per the application guides, re-inspections are typically conducted within 1–2 weeks of request.
