The planned neighborhoods of 92660, built from the early 1960s into the 1970s on the bluffs above the Back Bay and in the hills behind Fashion Island. This is also where our office is, on MacArthur Boulevard.
Homes in Eastbluff, Harbor View and Big Canyon were mostly built in the 1960s and 1970s, often on concrete slabs. The common plumbing calls are slab leaks, copper pinhole leaks, whole-house repipes and water heater replacements, often coordinated with an HOA. Water may come from the City or IRWD depending on your street. Call (949) 620-1945.
Nearly half the homes in 92660 were built in the 1960s and 1970s, and most of their plumbing problems trace back to that era. Many of these planned-community homes sit on concrete slabs with copper supply lines running under or through the floor.
After 50 years or more of hard water and use, copper can thin until small leaks open. In a slab home, a hot water leak under the floor shows up as a warm spot, a hissing sound or a water bill that climbs for no reason. One leak often means more are coming, which is why many owners in these neighborhoods choose a full repipe after the second or third repair.
In the Port Streets, Newport Beach Magazine describes original tract homes alongside heavily remodeled and fully rebuilt ones. The same is true across Eastbluff and Harbor View. A remodeled kitchen can sit on top of original supply lines in the slab, so it pays to ask what is under the floor before a remodel starts.
Each phase of the Port Streets has its own pool, clubhouse and homeowners association, and many 92660 homes are attached townhomes or condos. A leak in one unit can reach a neighbor, and HOA rules may control work hours, access and who pays for what. We can send proof of insurance to your association and coordinate with your manager.
In a gated golf community like Big Canyon, homes tend to be larger, with more bathrooms, more than one water heater and recirculation systems. Add us to your gate list before we arrive.
Many attached homes put the water heater in a garage corner, a hall closet or the attic. Attic units are the riskiest, because a leak comes down through the ceiling. The City's water heater checklist calls for a 22 by 30 inch attic access opening, with a light and an outlet at the unit, and a drain pan with a drain line protects the ceiling below. When an attic water heater nears the end of its life, replacing it before it leaks is worth considering.

92660 is split between the City of Newport Beach and the Irvine Ranch Water District, so your bill decides who to call for the street side.
| Problem | Who handles it | Number |
|---|---|---|
| Leak in the street, City customers | City of Newport Beach Utilities | 949-644-3011 |
| City water emergency after hours | Newport Beach Police, who dispatch a City crew | 949-644-3717 |
| IRWD water or sewer customers | Irvine Ranch Water District | (949) 453-5300 |
| Gas smell | SoCalGas, from outside | 1-800-427-2200 |
| Leaks and clogs on your property | A plumber | (949) 620-1945 |
Plumbing permits come from the City of Newport Beach Building Division at 100 Civic Center Drive, whichever agency supplies your water. See our permit guide and who to call for water and sewer.
Both materials work well in Newport Beach homes when installed correctly. The choice is about budget, walls and how long you plan to stay.
In townhomes and condos, check your HOA's rules before choosing, since some associations set standards for materials or require notice. A repipe in a typical 92660 slab home runs new lines through the attic and walls instead of the slab, so the old pipe in the floor is simply abandoned.
Eastbluff, the Port Streets, Harbor View Hills, Big Canyon and Bayside were built within roughly a decade of each other, but they were built differently.
| Neighborhood | Homes | Common plumbing work |
|---|---|---|
| Eastbluff | Planned village from 1963 on the bluffs above the Back Bay; detached homes, townhomes and condos | Slab leaks, repipes, unit-to-unit leaks, water heaters in garages |
| The Bluffs | Homes on the bluffs next to Eastbluff, with sewer service from IRWD | Slab leaks, sewer laterals, HOA coordination where it applies |
| Harbor View Homes (the Port Streets) | Late 1960s and early 1970s tract homes in three phases, many remodeled or rebuilt | Copper pinhole leaks, remodel repipes, sewer laterals |
| Harbor View Hills | Opened in 1971 in the hills toward Corona del Mar | Pressure regulators on sloped streets, repipes, water heaters |
| Big Canyon | Gated golf course community from the early 1970s with larger homes | Recirculation pumps, multiple water heaters, high-end fixtures |
| Newport Center and Fashion Island | Offices, shops and restaurants completed from 1967 | Commercial drains, restrooms, after-hours repairs |
The common thread is the decade. Homes finished between the early 1960s and the late 1970s now carry supply and drain lines that are 45 to 60 years old, unless an owner has already repiped. The difference is mostly in access: a detached Port Streets home can be repiped from the attic in a few days, while a townhome repipe may need the HOA's approval and coordination with neighbors.
Most original homes here were built on slabs with copper supply lines and cast iron or early plastic drains, and the remodel history decides what is still original.
| When the home was built | Supply pipe you often find | Drain and sewer pipe you often find | What tends to fail first |
|---|---|---|---|
| Early to mid 1960s | Copper, often in or under the slab | Cast iron, clay or cast iron lateral | Hot water slab leaks, scaled cast iron drains |
| Late 1960s and 1970s | Copper | Cast iron or ABS plastic | Pinhole leaks, worn pressure regulators, original water heater locations |
| Remodels since the 1990s | PEX or copper in the remodeled rooms | ABS in remodeled rooms, original lines elsewhere | The original lines the remodel did not reach |
| Full rebuilds | PEX or copper | ABS or PVC | Fixtures, tankless units, any lateral that was reused |
In slab homes of this age, the decision usually comes after the second or third leak. A single leak in sound copper can be repaired. Repeated pinholes in different places tell you the pipe itself is thinning, and each repair opens another floor or wall. A repipe runs new PEX or copper overhead and abandons the old lines in the slab, which ends the cycle. See whole-house repiping and leak detection.
Many townhomes put the water heater in the garage, a hall closet or the attic. When a tank in an upstairs closet or attic fails, the water goes straight down into the ceiling below, sometimes a neighbor's. A drain pan piped to a safe outlet, and replacing an aging tank before it leaks, are cheap insurance.
In a California common interest development, the association generally repairs common areas and each owner maintains their own unit, unless the governing documents say otherwise.
That default comes from Civil Code 4775. The association is responsible for repairing, replacing and maintaining the common area. The owner is responsible for their separate interest. For exclusive use common areas, like a patio or balcony assigned to one unit, the owner maintains it and the association repairs and replaces it. Every one of those rules can be changed by the association's declaration, so your CC&Rs are the final word.
For plumbing, the hard question is usually where a pipe sits. A supply line inside your wall that serves only your unit is often yours. A shared drain stack or a main line that serves several homes is often the association's. We find and document the source of a leak, with photos and notes, so you, your neighbor and your manager are working from the same facts.
The plumbing checks that save the most money in Eastbluff and Harbor View are a sewer camera inspection, a look at the supply pipe, and the water heater's age, permit and bracing.
A standard home inspection looks at what is visible. It does not run a camera through the sewer lateral or tell you what is inside the slab or walls. In an area where many homes carry original pipe, those hidden parts are where the big bills come from.
State law requires every residential water heater to be braced, anchored or strapped against earthquake motion, and a seller must certify in writing to the buyer that this has been done (Health and Safety Code 19211). A separate law, Civil Code 1101.4, required owners of single-family homes to replace noncompliant, high-flow plumbing fixtures by January 1, 2017, and requires sellers to disclose in writing whether the home has any.
Neither rule is hard to meet. A strap kit and a few low-flow fixtures cost far less than a delayed escrow, so we check both on a pre-listing visit.
Slab leaks do not follow a calendar, but water heaters and drains do.
These neighborhoods wrap around some of the city's best-known places. The Upper Newport Bay Nature Preserve and Ecological Reserve, about 1,000 acres of open space, sits below Eastbluff, with the Peter and Mary Muth Interpretive Center at 2301 University Drive. Fashion Island and Newport Center sit at the top of the hill, and Big Canyon Country Club anchors the gated community. What leaves a yard drain here reaches the bay untreated, so drain water heaters and pools into the sewer, never the gutter.
Close your main shutoff, and if water is coming from above, let your neighbor and HOA manager know.
We trace the leak to a unit, a line or a fixture, using moisture meters and leak detection rather than guesswork.
Photos and notes on where the leak started help you and your HOA sort out insurance.
You approve a written price for the repair before work starts.
Work that needs a City permit, like a reroute or water heater, is permitted and inspected.
A real person answers 24 hours a day. You get an honest arrival window and a written price before any work starts.
It depends on your street. Parts of 92660 are served by the City of Newport Beach and parts by the Irvine Ranch Water District, and IRWD handles sewer for The Bluffs and areas along SR-73. The agency name on your water bill is the surest answer.
Copper supply lines in homes of that age have carried hard water for 50 years or more. Over time the pipe can thin until pinholes open, often under a slab. When leaks repeat, a repipe usually beats repeated repairs.
It depends on your HOA's rules and your insurance. We find and document the source so you, your neighbor and your association have the facts. Check your CC&Rs and your manager for who covers what.
Our office is at 4490 MacArthur Blvd Ste 100 in 92660, close to these neighborhoods. Arrival times still depend on traffic and the day's calls, so we give you an honest arrival window when you call.
Larger homes often rely on a recirculation pump to keep hot water near the fixtures. When the pump, its timer or a check valve fails, the wait gets long. It is usually a straightforward repair.
Yes. A repipe needs a City of Newport Beach plumbing permit and inspection, whichever agency supplies your water. We pull the permit and schedule the inspection.
Under California Civil Code 4775, the association generally handles common areas and each owner handles their own unit, unless the CC&Rs say otherwise. Where the leaking pipe sits usually decides it. We document the source so you and your manager can sort it out.
Yes, with the association's approval where its rules require it. We can send proof of insurance, work within HOA hours and plan access with neighbors when shared walls are involved.
Slightly. The Port Streets were built in the late 1960s and early 1970s, and Harbor View Hills opened in 1971. Both are now old enough that original copper and water heaters are worth checking.
Ask for a meter leak check, the age of every water heater and the recirculation pump, a pressure reading, and any records of past repipes or slab leak repairs. Larger homes have more equipment, and replacing it on your schedule beats an emergency.
The usual causes are a failed water heater in an upstairs closet or attic, a leaking supply line, or a shower or toilet seal. Shut off your water if the source could be yours, alert your neighbor and manager, and call us to trace it.
