Street Cuts, Encroachment Permits and Pavement Moratoriums in California: The Second Permit Your Quote Forgot
Most California homeowners replacing a sewer lateral or water service line learn about the second permit at the worst moment: after the trench is open. The building department permit everyone talks about covers work on your property. The moment a shovel crosses the property line into the sidewalk, parkway strip, curb or roadway, you are in the public right-of-way — a different department, a different review, and costs that rarely appear on a first estimate.
None of this is one statewide rule. Every city and county writes its own right-of-way ordinance, and neighboring cities differ sharply. What follows is the pattern that repeats across California public works departments, and the questions that let you price it before you commit.
Two permits, two departments
The first is the plumbing or building permit for work on private property — covered in our guide to plumbing permits in California. The second goes by different names: encroachment permit, street-cut permit, excavation permit, right-of-way permit, or in Los Angeles an "E" or "U" excavation permit. Some cities add a separate obstruction permit to close a lane or block a sidewalk; Oakland treats excavation and obstruction as two distinct authorizations. The building department can approve your job while public works has not, and on a sewer line replacement where the failure is out near the main, the public works permit is usually the one on the critical path.
What an encroachment permit actually asks for
The packet varies, but California cities converge on the same short list:
- Proof of insurance — general liability naming the city as additional insured, at limits the city sets.
- A bond or cash deposit guaranteeing the restoration, held for a warranty period after acceptance; Oakland retains it for three years. Amounts are set by the city and can be substantial.
- A traffic control plan for anything in a travel lane, and often for sidewalk closures — on busier streets, a site-specific engineered plan rather than a generic detail sheet.
- Inspection fees, plus in many cities reimbursement of the city's actual staff and consultant time.
- Restoration to the city's trench detail: specified base, controlled backfill compaction, and a paving section wider than the trench itself — commonly a "T-section" or a grind-and-overlay extending beyond each edge of the cut.
Before any of it, the dig needs an 811 locate — see our guide to calling 811 before digging in California. The street is where utility density is highest.
The pavement moratorium: the part that changes the whole job
Cities spend heavily on repaving, and most California cities protect that investment by refusing or heavily restricting cuts into recently resurfaced streets for a set number of years. The period differs sharply city to city:
- San Francisco: five years after a street is reconstructed, repaved or resurfaced, with cuts allowed only by a discretionary waiver that can carry extra conditions and fees.
- Long Beach: 60 months after construction, reconstruction or resurfacing and 24 months after a slurry seal; outside emergency repairs and new service connections, the permit becomes discretionary and goes to the City Council.
- San José: three years, with an interactive moratorium map and an open dataset of affected segments you can check yourself.
- San Diego: moratoriums for both resurfacing and slurry seal, a formal waiver application, and a street damage fee on protected streets.
- Los Angeles: one year — shorter, but a cut can trigger repaving the block curb face to curb face.
Sacramento and its county add a wrinkle: a thin surface treatment like a chip seal, slurry seal or micro-surfacing starts its own moratorium clock, so a street that only got a light touch-up may still be protected. The specific numbers matter less than the habit: find out whether your street is under moratorium before you agree to an open-cut repair. Call the public works counter with your address, or check the city's moratorium map if it publishes one. The answer can change the repair method entirely.
Why cities do this — the research behind the rule
Moratoriums look arbitrary until you see the pavement engineering, because a cut does not only damage the rectangle it removes. The 1995 University of Cincinnati study by Bodocsi, Pant, Aktan and Arudi, "Impact of Utility Cuts on Performance of Street Pavements", found measurable weakening extending roughly three feet beyond the edge of a properly restored cut — which is why cities write restoration details that pave well past the trench width. Tighe, Knight, Papoutsis, Rodriguez and Walker, in the Canadian Journal of Civil Engineering in 2002 on user cost savings from eliminating pavement excavations through trenchless technologies, put the loss at roughly a 30% reduction in remaining pavement life once a road has been excavated. And Ghosh, Montgomery Dunn and Petersen used a California city's own pavement data — Pacifica's, spanning 15 years of distress records — to build a utility cut fee schedule ("Utility Cut Impact Assessment and Fee Development Using Pavement Management System", Transportation Research Record). That is the logic behind street damage fees: cities are billing for measured lost pavement life, not inventing a penalty.
How moratoriums push jobs toward trenchless — and when they don't
Once restoration and moratorium exposure are on the table, the comparison between digging and not digging often flips: a cured-in-place liner or a pipe burst pulled between two access points may cost more per foot than open trench but avoids the street cut entirely. See our guides to trenchless sewer replacement methods and epoxy and CIPP pipe lining costs.
Be clear-eyed about the limits: trenchless is not always no-dig in the right-of-way. Pipe bursting needs an insertion pit and a receiving pit, and if the connection at the city main is the failed part, one pit lands in the street or parkway anyway. A liner cannot fix a collapsed connection at the main and cannot create a new tap. In those cases you are back to an encroachment permit — with a much smaller opening, which matters when restoration is priced by area. The same calculus applies to a main water line replacement or a new connection under our water service tap fee guide.
Who pulls the permit — and why your plumber's city history matters
The contractor normally pulls the encroachment permit, not the homeowner: the insurance certificate and bond have to be in the contractor's name. This is where a cheap bid quietly falls apart. A plumber who has never worked in that city may not be registered with its public works department, may not carry the required limits, and may not have a bond on file.
Classification matters too. The Contractors State License Board recognizes several classifications that may install or repair a building sewer — "A" General Engineering, C-36 Plumbing, C-42 Sanitation System and C-34 Pipeline — and some local jurisdictions restrict right-of-way work further, so a C-36 plumbing license alone is not automatically enough for the street portion. Ask, for your city, before accepting a bid.
Sidewalk, curb and gutter: who restores what
The California default surprises people. Streets and Highways Code sections 5610 and following place the duty to maintain the sidewalk fronting a property on the abutting property owner, not the city — though section 5610 carves out conditions created by someone else under a city permit, and many cities run repair or cost-sharing programs that soften the rule. Curb and gutter are usually city-maintained, but damaging them during your job makes restoring them part of your permit. If the trench takes out a sidewalk panel or saws the curb, budget for replacing the full panel to city standard rather than patching it, and expect a driveway approach or curb ramp in the work area to pull accessibility requirements into scope.
What to ask before you sign
- Is my street under a pavement moratorium? Ask by address, and ask when it was last resurfaced or slurry sealed.
- Is the encroachment permit a separate line item? It should not be buried in "permits and fees" with the building permit.
- Is traffic control priced separately, and does the city require an engineered plan on this street?
- What restoration detail applies — trench width only, a T-section, grind-and-overlay, or curb-to-curb repaving? Get it in writing.
- Is there a street damage or degradation fee on top of the permit?
- Is the contractor already registered and bonded with this city?
