Huntington Beach ADU Market Update – July 2026
Huntington Beach is one of the most range-bound ADU markets in Orange County — in a good way. You've got entry-level coastal duplex plays under $1.6M sitting in the same city as $4.9M Huntington Harbour waterfront estates, and the ADU dynamics behind each deal are completely different. What holds across every price point is this: permitted ADUs are commanding premiums, properties with income in place are moving faster than vacant ones, and buyers shopping Surf City are doing serious underwriting before they write offers.
Here's a full look at what's active, what's pending, and what's closed — with the actual comp data behind each one.
What's Active Right Now
1209 Huntington St — $1,790,000 | 92648 | Active | 219 Days on Market
A 3-bed/2-bath, 1,440 sq ft home in West Huntington Beach (Area 15), priced at $1,243/sq ft on the main home. What makes this one notable is the ADU: a detached, fully permitted 838 sq ft unit built in 2022, with separate electric, gas, and water meters and its own alley access. The ADU is currently occupied.
At 219 days on market, this is a long runner — originally listed at $1,850,000 in November 2025 before a price reduction in February. The location is strong (walkable to the beach, Pacific City, and Main Street), and the ADU adds real income potential. What's likely keeping buyers cautious is the lack of garage parking and a 3,078 sq ft lot that leaves limited room for expansion. That said, a 2022-built detached ADU with separate meters in downtown HB is a real asset — how that ADU is treated at appraisal on a financed offer will matter here, and a permitted unit this new is in the best possible position for the income approach.
7736 Sugar Dr — $2,600,000 | 92647 | Active | 61 Days on Market
This one is unlike anything else in the current Huntington Beach ADU market. It's a gated family compound on a massive 22,800 sq ft lot in Northwest HB — three separate structures totaling 7 bedrooms and 5 bathrooms, 4,250 sq ft of living space, and 15 garage spaces. The ADU situation here is unusual: two separate income units, one a 700 sq ft studio currently rented and one a 900 sq ft 2-bed/1-bath unit also currently rented.
At $611/sq ft, this is actually one of the lowest price-per-foot entries in the current Huntington Beach ADU market despite the $2.6M price tag — the sheer square footage, lot size, and income-in-place pull that number down significantly. The seller is open to concessions and accepts FHA, VA, and conventional financing in addition to cash. For a buyer who wants scale, privacy, and dual rental income in a coastal community, the math here is genuinely different from a standard SFR-plus-ADU play. The tradeoff is a 1950 main structure with a 61-day run already, which tells you the buyer pool is specific.
16572 Grimaud Lane — $4,950,000 | 92649 | Active | 149 Days on Market
Huntington Harbour is its own market within a market, and 16572 Grimaud is the cleanest current example of what waterfront ADU property looks like at the top of the range. This is a fully remodeled 5-bed/4.5-bath, 4,238 sq ft home on one of only 22 lots on the prestigious "ocean side" of Grimaud Lane — with a 60-foot waterfront terrace, private boat dock, Wolf/Sub-Zero/Viking kitchen, and a detached casita (Junior ADU, 400 sq ft) currently vacant.
Originally listed at $5,350,000 in January 2026, it's been reduced to $4,950,000 — a $400K cut after 149 days. The JADU at this price point is more of an amenity feature (guest quarters, home office, private studio) than an income-driver, and the shared meter situation reflects that. The HOA is minimal at $12/month, which covers dock access. Cash, cash-to-new-loan, and owner-may-carry are the accepted terms — no conventional financing listed here. This is a patient seller and a narrow buyer pool.
What's Pending
16842–16846 Lucia — Listed $1,599,900 | 92647 | Under Contract as of 6/27/26
This is the most interesting comp in the current Huntington Beach ADU set. A duplex on a 7,425 sq ft lot in Northeast HB — a beautifully remodeled 1,293 sq ft main residence with 3 bedrooms and 2 bathrooms, plus a fully permitted 440 sq ft studio Junior ADU with its own kitchen, bath, laundry, and split A/C. The property also has a resort-style pool and spa, 36 solar panels, and 3 Tesla Powerwall batteries (leased).
It went under contract on 6/26/26 — 40 days after hitting the market on 5/22/26. The listing agent notes the lot could potentially support up to 2 additional units with proper permits, which is the kind of upside that makes investor buyers move. The JADU's income potential combined with a ready-to-use pool home is a strong lifestyle-plus-cash-flow combination. Using ADU rental income to qualify for the mortgage will be a factor for the winning buyer here — especially given that the solar lease carries forward.
121 Alabama St — Listed $2,100,000 | 92648 | Pending as of 6/20/26
A 4-bed/3.5-bath, 2,922 sq ft three-story beach retreat just blocks from the sand and Pacific City in South HB — with a separate loft mother-in-law quarters above the garage that functions as a standard ADU (1 bed, 1 bath, upper level, separate entrance). The ADU is currently vacant.
Originally listed at $1,975,000 in March, it was repriced to $2,100,000 by late May — unusual to see a price increase on a property that came back to market, but the listing notes ocean peek-a-boo views and two fireplaces. It went pending in 34 days from the repriced start. At $718/sq ft, this is a relative value play for the 92648 zip code given its proximity to the pier and Main Street. The ADU's shared meter situation is worth noting on a financed deal — how lenders treat ADU income depends heavily on permit status and meter configuration.
1701 Lake St — Listed $1,850,000 | 92648 | Pending as of 6/29/26
This one moved fast. A zoned R-2 corner lot in the Downtown HB neighborhood — a 1,505 sq ft main home (4 bed/2 bath, built 1954) and a fully detached 1,359 sq ft guest house (2 bed/2 bath, built 1990) on a 5,876 sq ft lot. The ADU here is as close to a full second home as you'll find: separate address, separate meters, its own garage, two levels, upstairs living room with balcony, and soaring ceilings in the primary suite.
Listed on 6/8/26. Purchase contract signed 6/13/26. Five days on market — no price changes, no games. The sellers received a contract in under a week at their original ask. The accepted terms include Fannie Mae financing, which signals a conventional buyer — Fannie Mae's ADU guidelines allow income from a properly documented, separately metered ADU to factor into qualification, and a 1,359 sq ft detached unit with separate meters is positioned as well as anything in this data set for that treatment. Zoned R-2 with potential to add units is the icing.
What's Closed
302 3rd St — Listed $4,495,000 / Closed $4,317,375 | 92648 | Closed 5/29/26
The standout closed comp in Huntington Beach ADU for the quarter. A 2023-built Modern Mediterranean just two blocks from the beach — 4 bed/5.5 bath, 3,747 sq ft, designed by Thomas Price Custom Builders with a fully permitted private ADU (870 sq ft, 1 bed/1 bath, separate address), nearly 1,900 sq ft of rooftop and terrace space, a 2024 Sundance Spa, a built-in outdoor kitchen with pizza oven and kegerator, and a Control4 smart home system throughout.
It sold for $4,317,375 — cash buyer, $177,625 under list after 62 days on market. The buyer conceded $32,380 to cover the buyer broker fee. At $1,152/sq ft, this is the most expensive close in the current Huntington Beach ADU set and one of the highest price-per-foot closes in the 92648 zip code this year. The ADU is included in that price as a built, permitted, ready-to-use unit — which is exactly what distinguishes new construction ADU product at the high end. Compare this to the 1209 Huntington St situation (838 sq ft ADU, 219 days on market): location, build year, and overall presentation all do heavy lifting in where an ADU property ultimately prices.
What the Numbers Are Telling Us
A few things stand out when you look at this data together.
Huntington Beach spans more price range than any other OC ADU market. From the $1,599,900 Lucia duplex to the $4,950,000 Grimaud waterfront, that's nearly a $3.4M spread within a single city. The ADU type, lot size, zip code, and proximity to water are doing most of that work — more so than the ADU itself. Knowing what your home with an ADU is worth in Huntington Beach means understanding which pocket and which ADU configuration you're comparing against, because the comps don't translate across these segments.
Properties with separate meters and separate addresses are moving first. 1701 Lake St (separate meters, separate address, separate garage) went pending in 5 days. 16842 Lucia (shared meters but permitted JADU with separate entrance) went pending in 40. 1209 Huntington St (occupied ADU, separate meters) has sat 219 days — the price and lot constraints are the likely drag, not the ADU itself. Under California's ADU law, separately metered units have always commanded better lender treatment and buyer confidence, and this data reinforces that.
Waterfront and premium coastal product is repricing. Grimaud has dropped $400K from its original list. 302 3rd sold $177K under ask. The high-end buyer pool in Huntington Beach is active but disciplined — they're not chasing, and they're willing to wait for the right price. Sellers at $4M+ need to price into that reality from day one. This is a meaningfully different dynamic than what we're seeing in Costa Mesa's ADU market, where well-positioned mid-range ADU properties are still going under contract in under 10 days.
R-2 zoning and ADU-ready lots are a specific buyer magnet. 1701 Lake St's R-2 designation and the Lucia listing's note about potential additional units both attracted fast contracts. Buyers who understand California's ADU state law and what's possible on zoned lots are underwriting potential — not just current income — which gives those sellers pricing leverage that a standard SFR doesn't have.
How Huntington Beach Compares to Nearby Markets
Huntington Beach currently prices higher on a per-foot basis for coastal and downtown ADU product than Anaheim or Garden Grove — but the cash-flow math is harder to make work at 92648 zip codes. A buyer looking to maximize monthly income relative to purchase price is better positioned in Garden Grove, Anaheim, or the Long Beach corridor. A buyer buying for land, lifestyle, and long-term appreciation trajectory buys Huntington Beach.
The markets where you'd buy for cash flow don't look like this data set. Huntington Beach buyers are generally underwriting a blend — some income from the ADU, significant appreciation upside, and the lifestyle value of coastal Orange County. That's a different profile from a pure income investor, and the deals that move fastest here reflect that buyer's priorities.
