If your work touches Phoenix's streets, sidewalks, utility corridors, or any public land — even for a single day — the City of Phoenix Street Transportation Department has specific insurance requirements you must meet before your crew sets foot in the right-of-way. These requirements were updated as recently as January 2025, and they are not light. Miss a single coverage or submit your COI to the wrong department, and you will not be starting work on schedule.
This article breaks down exactly what the City requires, why each coverage matters for ROW and Public Utility Easement (PUE) work, and the procedural details that catch contractors off guard — including where to send your certificates and what happens if your policy lapses mid-project.
▶ Key Takeaways
- Four coverages are required: Commercial General Liability, Automotive Liability, Workers' Compensation, and Contractor's Pollution Liability — all with specific limits and endorsements.
- Contractor's Pollution Liability is not optional. Phoenix requires it for all ROW/PUE work, with limits of $1M per occurrence and $2M aggregate. Asbestos, lead, mold, and sediment coverage must not be excluded.
- The City of Phoenix must be named as additional insured on the GL, Auto, and Pollution Liability policies — and your coverage must be primary and non-contributory.
- Workers' Compensation employers' liability limits were revised upward to $1,000,000 across all three sub-limits as of January 2025.
- Send COIs to the City Utility Inspections Administrator at 1101 E Jefferson St, Phoenix, AZ 85034 — not to Risk Management.
- Failure to maintain required insurance is a material breach. The City can prohibit you from working in the ROW until coverage is reinstated.
Who These Requirements Apply To
These insurance requirements apply to contractors performing work in the City of Phoenix's right-of-way (ROW) or public utility easements (PUE) on behalf of a Licensee — typically a utility company, developer, or other entity holding a permit or license from the City to conduct operations in public space. If you are the contractor doing the physical work — excavating, installing conduit, laying pipe, patching pavement, doing any form of utility work or street work in Phoenix — these requirements apply to you, regardless of whether you are the prime contractor or a subcontractor.
The requirements are described as minimum requirements. The City explicitly states they do not limit indemnity obligations under the license agreement, and contractors are free — and may sometimes be required by the Licensee — to carry higher limits. In practice, the Licensee (your client) may impose additional requirements on top of the City's minimums, so always compare what the Licensee's contract requires against the City's floor.
The Four Required Coverages — With Exact Limits
1. Commercial General Liability (Occurrence Form)
Phoenix requires a standard commercial general liability policy written on an occurrence form — not claims-made. The required limits are:
| Limit Type | Required Amount |
|---|---|
| General Aggregate | $2,000,000 |
| Products & Completed Operations Aggregate | $1,000,000 |
| Personal and Advertising Injury | $1,000,000 |
| Each Occurrence | $1,000,000 |
The policy must name the City of Phoenix as an additional insured for bodily injury, property damage, and personal and advertising injury — covering both ongoing operations and completed operations. Your coverage must be primary and non-contributory with respect to all other available sources, meaning the City's own insurance does not contribute to a loss arising from your work. A waiver of subrogation in favor of the City is also required.
If the "project" box is checked on the ACORD COI, you must include the following language in the description of operations field: "Covers all projects and locations within City of Phoenix." This is a common Phoenix-specific requirement that trips up contractors who copy a generic certificate from another jurisdiction.
2. Automotive Liability
Any vehicle used in the performance of work in the City — owned, hired, or non-owned — must be covered under a commercial auto policy with a combined single limit of $1,000,000. This covers bodily injury and property damage arising from vehicle use in connection with your operations.
The auto policy must be endorsed to include the City of Phoenix as an additional insured for liability arising out of your activities. As with the GL, your auto coverage must be primary and non-contributory, and the policy must include a waiver of subrogation in favor of the City.
One practical note: if your employees drive their personal vehicles to and from job sites and occasionally use them for work errands, those vehicles are "non-owned" from the standpoint of your business. Make sure your commercial auto policy includes hired and non-owned auto coverage — a standalone HNOA endorsement if needed — so that gap is closed before a Phoenix ROW project kicks off.
3. Workers' Compensation and Employers' Liability
Workers' compensation coverage at statutory limits is required. The employers' liability sub-limits were revised effective January 9, 2025, and are now set at $1,000,000 across all three categories:
| Limit Type | Required Amount |
|---|---|
| Each Accident | $1,000,000 |
| Disease – Each Employee | $1,000,000 |
| Disease – Policy Limit | $1,000,000 |
This is a significant increase from the prior standard $100,000 employers' liability limits that many standard WC policies default to. If your policy was written before January 2025 and has not been updated, there is a good chance your employers' liability sub-limits are too low for Phoenix ROW work. Check your declarations page before you submit your COI. A waiver of subrogation in favor of the City is also required on the WC policy.
The sole proprietor exemption applies: if you are a sole proprietor exempt from workers' compensation under Arizona Revised Statute §23-902(E) and you execute the required sole proprietor waiver form, this requirement does not apply to you personally. However, if you have any employees — even one part-time laborer — the exemption disappears and full WC coverage is mandatory.
4. Contractor's Pollution Liability
This is the requirement that surprises contractors most — and the one most likely to create a delay if you do not have it in place before you start the Phoenix permitting process. Contractor's Pollution Liability (CPL) is required for all ROW and PUE work in the City of Phoenix, with no exceptions for trade type or project size.
| Limit Type | Required Amount |
|---|---|
| Per Occurrence | $1,000,000 |
| General Aggregate | $2,000,000 |
The policy should be written on an occurrence basis with no sunset clause. If it is written on a claims-made basis, Phoenix requires that you maintain the policy for at least nine years after project completion, with a retroactive date held constant at or before the contract commencement date. That nine-year tail requirement makes occurrence-form CPL the practical choice for most contractors.
The City of Phoenix must be named as an additional insured on the pollution policy, along with its subsidiaries and affiliates. The scope of required coverage is notably broad and specifically must include:
- Bodily injury, sickness, and disease — including death and medical monitoring costs
- Property damage — including cleanup costs, loss of use, and diminution in value
- Environmental damage — soil, surface water, groundwater, plant and animal life, and cleanup costs
- Defense costs — investigation, adjustment, and defense of covered claims
- Asbestos and lead — no exclusion permitted
- Mold and Legionella — must be covered
- Transportation cargo
- Non-owned disposal site coverage
- Sediments — must be included in the definition of pollution conditions
Many standard contractor pollution policies exclude asbestos, lead, or mold — or include them only by endorsement. Do not assume your existing CPL policy satisfies Phoenix's requirements without having your broker confirm each of these coverage elements against the policy language. A COI that says "pollution liability" but does not reflect these specific inclusions will not satisfy the Utility Inspections office.
"Contractor's Pollution Liability is required for all Phoenix ROW work — no exceptions for trade type or project scale. If you do not have it, you are not getting a permit."
The Additional Insured and Endorsement Requirements
The City of Phoenix requires additional insured status on three of the four required policies: General Liability, Automotive Liability, and Contractor's Pollution Liability. Workers' Compensation does not carry an AI requirement, but it does require a waiver of subrogation.
For the GL policy specifically, the additional insured endorsement must cover both ongoing operations (ISO CG 20 10 or equivalent) and completed operations (ISO CG 20 37 or equivalent). This is a detail that matters after your project wraps up — completed operations coverage extends the City's protection through the policy's completed operations aggregate for claims that arise after your work is done. If your policy's AI endorsement only covers ongoing operations, you are non-compliant with Phoenix's requirements even if the COI does not flag it.
The primary and non-contributory requirement applies to both the GL and Auto policies. This must be backed by an endorsement — ISO CG 20 01 or a manuscript equivalent — not simply stated in the description box of the certificate. A COI that notes "primary and non-contributory" in the description box without the actual endorsement on the underlying policy is a compliance risk if a claim triggers the coverage.
Waivers of subrogation are required on all four policies. These must be endorsed onto the policy and cannot be added retroactively on most carriers. If you are setting up insurance for a new Phoenix ROW project, confirm with your broker that all four policies carry blanket waiver of subrogation endorsements before work starts.
Insurer Standards
Phoenix requires that all insurers be licensed or authorized to do business in Arizona and hold an A.M. Best rating of not less than B+ VI. This is a moderate standard — B+ is the fourth-highest financial strength rating, and Size Category VI indicates policyholder surplus between $25 million and $50 million. Most major admitted commercial carriers easily exceed this threshold, but surplus lines or specialty carriers used for pollution liability should be verified. If your broker places your CPL with a specialty market, confirm the carrier's A.M. Best rating before you submit the certificate.
Do not send certificates of insurance to the City of Phoenix Risk Management Division. All certificates must go directly to the City Utility Inspections Administrator at the Street Transportation Department. Sending to the wrong office is a common mistake that delays project authorization.
COI Submission: Where to Send It and When
All certificates of insurance must be received and approved by the City before any work commences. This is not a suggestion — it is an explicit requirement, and failure to provide evidence of coverage before starting is a material breach of the license agreement. Plan for enough lead time to get your COI issued, submitted, and approved before your project start date.
Send certificates and all required endorsements directly to:
✉ COI Submission Address
- City of Phoenix Street Transportation Department
- Utility Inspections Administrator
- 1101 E Jefferson Street
- Phoenix, AZ 85034
The City reserves the right to request copies of declaration pages, applicable endorsements, and policy exclusions as they relate to the coverage requirements. Maintain organized policy documentation so that if the Utility Inspections office asks for backup, you can respond quickly without chasing your broker for records.
Certificates must be issued on the ACORD 25 form (or a City-approved equivalent) and signed by a person authorized by the insurer to bind coverage. A certificate issued by a broker representative — rather than a person with binding authority — may not be accepted.
Cancellation Notice Requirements
If any of the required policies is suspended, voided, or cancelled for any reason during the project, you must notify the City within 30 business days of receiving that notice from your insurer. Notification must be mailed or hand-delivered — not emailed — to the Utility Inspections Administrator at the address above.
Note that this is 30 business days from receipt of the notice, not 30 calendar days. But do not treat this as a comfortable runway. A cancelled policy means your coverage is gone from the cancellation date, and if your crew is still working in the ROW while coverage has lapsed, you are personally liable for any claims that arise in that window.
If your insurer sends you a non-renewal notice, treat it with the same urgency as a cancellation notice. Failure to maintain the required insurance — including failure to provide evidence of renewal — is a material breach that can result in the City prohibiting you from working in the ROW until coverage is reinstated.
Excess and Umbrella Coverage
Phoenix permits contractors to use an excess or umbrella liability policy to meet the minimum liability limits, provided the coverage is written on a "following form" basis. This means the umbrella must follow the terms and conditions of the underlying primary policy, not introduce exclusions or limitations that are not in the primary. If your umbrella uses a manuscript form with broader exclusions than your underlying GL, confirm with your broker that it will still satisfy Phoenix's following-form requirement.
A following-form umbrella can be an efficient way to meet Phoenix's $2M GL aggregate requirement if your primary GL is written at $1M/$1M, but make sure the umbrella drops down properly to cover gaps and that the City of Phoenix is included as an additional insured on the umbrella as well — something that is sometimes overlooked when the umbrella is treated as a pure excess layer.
What Happens If You Get This Wrong
Getting the insurance requirements wrong for Phoenix ROW work carries real operational consequences. The City will not authorize your work until compliant certificates and endorsements are received and approved. If you have already mobilized and the COI review reveals deficiencies, you may be required to demobilize until the issue is corrected — paying your crew to stand down while you scramble to fix insurance paperwork is an expensive problem that is entirely preventable.
Beyond project delays, non-compliance with these requirements is a material breach of the license agreement between your client (the Licensee) and the City. That breach can put the Licensee's permit at risk and create liability exposure back to you under your subcontract. Most Licensee agreements include insurance compliance as a condition precedent to payment — meaning if you are non-compliant, your client may have grounds to withhold payment until you cure the breach.
And in the event of an actual claim — an excavation that damages a utility line, a vehicle incident in the ROW, a contamination event from construction activities — a non-compliant or defective policy means the coverage you thought you had may not respond, or may respond in a way that leaves you personally on the hook for damages that your policy was supposed to handle.
Getting Your Coverage Set Up Before the First Phoenix Project
For contractors working primarily in California who are expanding into Arizona — or picking up project work in Phoenix specifically — the coverage structure for Phoenix ROW work is more demanding than what a typical California-focused policy provides. The key gaps to address:
- Employers' liability limits: Standard California WC policies often default to $100,000/$100,000/$100,000 employers' liability. Phoenix requires $1,000,000 across all three sub-limits. This is a mid-term change that requires insurer approval and will affect your premium. Budget for it.
- Contractor's Pollution Liability: Many California contractor policies do not include CPL at all, or include it as a limited endorsement that does not meet Phoenix's breadth requirements. A standalone CPL policy with the required occurrence form, no asbestos/lead/mold exclusions, and the City named as AI is often needed.
- Waiver of subrogation on all four policies: This must be in place at policy inception or renewal. If you pick up a Phoenix project mid-term and your policies do not carry blanket waivers of subrogation, you may need to add them by endorsement — which some carriers will do mid-term, and some will not.
- Arizona admitted carriers: If your California policies are placed with non-admitted surplus lines carriers, they must still be authorized to do business in Arizona and meet the B+ VI A.M. Best standard. Confirm with your broker before assuming your existing carriers qualify.
The right approach is to review the Phoenix requirements with your broker before you bid on the work, not after you win it. Knowing the insurance cost going in lets you price the project correctly. Getting surprised by a CPL premium after you have already bid at a number that did not account for it is a margin problem you do not want on a public-space project where change orders are not always available.
