If you own in Cliff Haven and plan to list in the next 24 months, the appraiser working your file is about to have a harder job. Two for-sale townhome projects have cleared or entered planning review on the inland edge of the neighborhood, and both sit inside a zoning overlay that most owners have never heard of. The projects are small. The pricing implications are not.
Here is the piece the portals will not tell you: Cliff Haven's 344 single-family homes have always been comped against each other. Starting with the 2027 delivery window, they will also be comped, incorrectly and often, against a new product type built a block away.
Two projects, one overlay
The Newport Beach Planning Commission voted 4-1 on February 5, 2026 to approve the Dover Townhomes at 601 Dover Drive, the corner of Cliff Drive, replacing a 1961 medical office on a 1.5-acre parcel. A second project, Westcliff at Dover, is moving through review at 1501 16th Street on the site of the former Newport Bay Hospital. Neither is speculative. Both carry planning case numbers, staff resolutions, and vesting tract maps.

Both parcels sit inside the HO-3 Dover-Westcliff Housing Opportunity Overlay, one of five overlays Newport Beach adopted to satisfy its 6th Cycle Housing Element obligation. The city's zoning code, chapter 20.28 of the Newport Beach Municipal Code, defines HO-3 as property on both sides of West Coast Highway and west of Dover Drive, with Lido Village properties included.
Why the overlay exists, briefly
State housing law assigned Newport Beach 4,845 units under the 2021 to 2029 Regional Housing Needs Assessment. The city concentrated that obligation into five inland corridors instead of spreading it across established beach neighborhoods. The Dover-Westcliff overlay carries a cap of 521 units, the smallest of the five focus areas. Two community groups, Still Protecting Our Newport and the Newport Beach Stewardship Association, sued to block the plan under City Charter Section 423. On June 18, 2025, Judge Melissa R. McCormick dismissed both suits, ruling that state housing law overrides the local charter requirement.
That ruling matters because it closed the door on the "this will get overturned" argument that some Cliff Haven owners have been using to discount the pipeline. It will not.
The comp problem, which is the whole point
Cliff Haven's existing stock is 344 single-family homes on 7,000 to 11,000 square-foot lots, most built in the late 1940s and early 1950s, many rebuilt in the last fifteen years. Non-portal market data compiled for the neighborhood shows single-family values running from roughly $1.5M for a smaller original home up to $7.5M for a large rebuild on a half-acre, with a rolling twelve-month median in the mid-$5M range as of early 2026. There is no HOA.
Now insert 63 attached townhomes, sized between 1,355 and 2,401 square feet, delivering in 2027 to 2028, on the inland edge of that same market. They will trade at a price point wholly disconnected from the SFR stock. They will also carry HOAs, shared parking counts, and disclosure covenants tied to the overlay itself, since chapter 20.28 requires each buyer, lessee, or renter to sign an acknowledgment of the urban character of the site.
Here is what happens next in a typical appraisal: an underwriter pulls a wider comp radius during a slow month, catches a Dover Townhomes closed sale inside a half-mile ring of a Cliff Haven listing, and the automated valuation model treats it as neighborhood data. It is not. But it will show up in the file.
The risk to Cliff Haven is not that the townhomes lower values. It is that they blur the comp set for the entry tier of the neighborhood, the two-bedroom original cottages on 7,000-foot lots, right at the price band where an appraisal cut can kill a deal.
The top tier of Cliff Haven, the rebuilt houses north of $5M with harbor and Back Bay views, will not comp against anything on Dover Drive. That segment is safe. The exposure sits at the lower end, and it is a documentation problem more than a pricing one.
Signals worth watching before you list
A short list of the specifics that will matter to your file, whether you are buying or selling in Cliff Haven between now and 2028:
- Recording of the Dover Townhomes tract map. A condition of approval requires the tract map to record before building permits issue. That date is the first hard signal that closed sales are coming.
- The SCE undergrounding condition. The commission conditioned approval on undergrounding the power pole along the project frontage pending Southern California Edison review. Expect Dover Drive to look like a construction corridor during that work.
- Right-in, right-out access at 601 Dover. If it is not installed before the HOA takes control, the developer must pre-fund reserves. Traffic on Dover Drive and Cliff Drive is the neighborhood-facing impact.
- Westcliff at Dover height. At approximately 44 feet across five buildings, this is the taller of the two projects. Sight-line effects for the north end of Cliff Haven will be real for a handful of parcels.
- Related California's Big Newport towers. Approved March 6, 2026 for the Regal Edwards theater site at 210 Newport Center Drive. Not adjacent to Cliff Haven, but a signal that the city's housing pipeline is moving from planning documents to steel.
What sellers should actually do
If you plan to sell in the next 18 months, price and market against the SFR stock, not the pipeline. That means disclosing the pending projects because California requires it, then giving your listing agent a clean argument for why your comp set stops at Kings Place and St. Andrews Road, not at Dover Drive.
If your home is at the lower end of Cliff Haven, the original two- and three-bedroom stock on smaller lots, this is the segment where a buyer's agent may push back with a Dover Townhomes closed sale as leverage. Anticipate it. The counter is architectural: single-family, no HOA, no shared walls, on a 7,000-foot lot in one of 344 homes in a subdivision that has not added a unit since the Truman administration. That story lives in the disclosures and in the marketing, and it is stronger when told first.
What buyers should ask
If you are buying in Cliff Haven this year, three questions belong in your offer letter or your inspection contingency period:
- Has the listing agent pulled comps that exclude HO-3 townhome pre-sales? Ask to see them.
- What is the appraisal gap coverage, and how does it treat automated valuation model comps drawn from the overlay?
- Is the property inside the sight-line envelope of either project's upper floors? A ten-minute walk with a tape measure answers this faster than a map does.
FAQ
Does the overlay allow projects inside Cliff Haven itself? No. HO-3 covers commercial and mixed-use parcels on both sides of West Coast Highway and west of Dover Drive, plus Lido Village properties. The 344 single-family lots inside the Cliff Haven tract are not opportunity sites and cannot be upzoned under this overlay.
Will the 521-unit cap be reached? Unlikely in this cycle. The Dover Townhomes and Westcliff at Dover together account for 63 of those units, roughly 12 percent of the cap. Additional projects will require willing sellers of commercial parcels and market conditions that support the math. The overlay removes regulatory friction. It does not force construction.
What is the disclosure requirement tied to the overlay? Chapter 20.28 requires a written disclosure statement acknowledging that the property sits in an urban environment where noise, odor, and outdoor activity levels may be higher than a typical suburban area. The covenant runs with the land and binds subsequent grantees. This applies to units inside the HO overlay, not to existing Cliff Haven SFRs, but adjacent owners should know it exists on the neighboring parcels.
Does any of this affect Mariners' Mile below the bluff? Indirectly. Mariners' Mile revitalization is a separate corridor plan aimed at pedestrian improvements and mixed-use zoning along Pacific Coast Highway between Dover Drive and Bayside Drive. The overlays and the corridor plan are complementary, not the same document, and the timing on Mariners' Mile is slower.
