City of Orange ADU Market Update — May 2026
The City of Orange ADU market told a clear story this month: buyers are still paying premiums for the right ADU home, but they're getting picky at the top end. Eleven ADU-flagged properties hit the radar in early May — eight actives, two pending, and one closed sale that went $25,000 over asking after just seven days on market.
If you've got an ADU home in Orange you're thinking about listing this summer, or you're a buyer hunting Old Towne and Chapman-area income properties, this update is for you.
The Headline Numbers

Active price range: $1,425,000 to $1,995,000
Active median list: ~$1,732,000
Active price/sqft range: $491.59 to $859.98
Pending: 2 (both went under contract in 10–12 days)

Long DOM outlier: 264 days (yes, really — more on that below)
What's Active Right Now in Orange
Old Towne Orange + Chapman corridor (the hottest pocket)
This is where the action is. Four of the eight active listings cluster within walking distance of Chapman University and the Orange Plaza, and they're priced for the income-producing buyer pool more than the owner-occupant.
130–132 S Lime St — $1,699,900 (down from $1,799,900). 6BR/3BA two-on-a-lot. Front home from 1949 (extensively remodeled 2020), back ADU built in 2021, both move-in ready. List speaks to about a 4.78% cap rate at $9,000/mo combined rent. 44 days on market with a $100K reduction tells you the seller is open to offers.
417 N Citrus St — $1,695,000. 4BR front + newly built 2024 ADU (2BR/1BA, 749 sqft). Both currently leased ($5,960 front, $3,200 ADU). Combined gross $9,160/mo at a stated 4.9% cap. Tenant occupied through May 2026 (front) and May 2027 (ADU) — meaning a buyer steps into immediate cash flow but inherits the leases.
359 N Harwood — $1,799,000. Old Towne historic district Craftsman from 1925. Front 3BR/3BA, plus a 420 sqft 1BR/1BA upper-level ADU above the detached garage. ADU is rented. Charm + income.
246 N Stevens — $1,529,900. Mid-century 4BR home with a brand-new, never-lived-in 524 sqft ADU completed in 2025. Separate electric meter, fully permitted. Just hit the market April 28.
Cambridge / N. Tustin area (premium owner-occupant ADU homes)
634 E Adams Ave — $1,995,000 (down from $2,088,000). 5BR/6BA pool home with 683 sqft permitted detached ADU built 2022, plans for a 235 sqft expansion to 2BR. Solar, EV charging, wheelchair accessible. Currently licensed as a short-term rental. 58 days on market, $93K price drop — high-end Cambridge buyers are taking their time.
390 N Milford — $1,665,000. Two-story 5BR/4BA with a 462 sqft attached Junior ADU configured as a private in-law suite with gated entrance. Solar owned. 23 days on market.
Larger lots, off-Plaza
178 N Monterey Rd — $1,995,000. "Kibby House" — 4BR ranch on a huge 11,340 sqft lot, 13 blocks east of the Plaza. Has an 830 sqft "workshop/ADU/game room" with a 3/4 bath and vaulted ceilings — buyers should clarify the actual permit status. Notable: there's a $607,000 assumable VA loan at 2.25% that's making this property interesting to a niche buyer pool.
2929 E Hamilton Ave — $1,425,000. This is the long-DOM outlier. 3BR/3BA on an 8,856 sqft cul-de-sac lot with a fully upgraded 600 sqft 1BR/1BA private ADU (shared meters). On market since August 13, 2025 — 264 days. At this point it's a pricing problem, not a property problem. Worth watching for a meaningful reduction.
Pending Sales — What Buyers Just Locked Up
Two ADU homes went under contract in early to mid-April. Both deserve attention because they tell different stories.
1402 E Rose Ave — $1,549,000 (pending in 12 days)
5BR/3BA pool home in Old Towne with a fully permitted 426 sqft ADU at 1404 E Rose — converted in 2023, separate water and electricity meters, vaulted ceilings, tankless water heater. Permitted, separately metered ADUs are exactly what buyers are paying full ask for. Resort-style backyard with a new pool didn't hurt.
914 N Sacramento — $1,100,000 (pending in 10 days) — the AB 2533 story
This one's interesting. Mid-century home (originally built in Malibu, relocated to Orange in the 1970s — yes, really) with a 644 sqft detached ADU. The ADU is unpermitted, but the listing notes it "should qualify for the AB 2533 Safe ADU Legalization Program," and the buyer signed up anyway at $1.1M.
This is a real-time example of what I cover in detail in Selling a Home With an Unpermitted Garage Conversion or Bootleg ADU — buyers in 2026 are no longer running from unpermitted ADUs the way they did three years ago, as long as the seller is upfront and the path to legalization is clear. AB 2533 (effective January 1, 2025) made this much cleaner. If you have an unpermitted unit in Orange, the market just told you you can sell it — at a discount, with the right disclosures, to the right buyer.
Closed Sale of the Month: 2225 E Grove Ave
Listed $1,300,000. Closed $1,325,000. On market 7 days.
3BR/2BA Craftsman from 1960 with an attached 500 sqft Junior ADU (1BR/1BA, kitchenette without oven/stove). 8,000 sqft lot, 1,920 sqft of main house. Closed April 17, 2026 with conventional financing.
A few things to read into the data:
Permitted Junior ADUs still drive over-asking offers in Orange when the home is otherwise turnkey.
The buyer paid full freight even though the ADU kitchenette doesn't have a full stove (stays a JADU, not a full ADU).
$37,125 in seller concessions (mostly $33K to the buyer's broker fee). Net to seller approximately $1,287,875 — still over original list and a clean 7-day deal.
If you're wondering what your Orange home with an ADU could realistically sell for, this is the freshest comp in the cluster. I break down the full valuation framework in How a Home With an ADU Is Valued When You Sell.
What This Means If You're Selling an ADU Home in Orange
A few clean takeaways from this month's data:
Permitted, separately metered ADUs are the gold standard. The two pendings and the closed comp all share this trait. Shared-meter and unpermitted units sell — but at meaningful discounts.
Old Towne / Chapman-corridor income properties want a 4.7%+ cap to sell. If the math doesn't pencil, expect a price reduction or extended DOM.
The $1.6M–$2M Cambridge segment is taking its time. Two listings in this band have already cut price. If you're listing here, price tight and stage well — buyers have options.
Don't sit too long. The 264-day Hamilton listing is a cautionary tale. After 60 days without a contract, the market is telling you something. Listen.
What This Means If You're Buying
The under-$1.5M ADU home is rare in Orange right now. Sacramento at $1.1M is the only one — and it went pending in 10 days even with an unpermitted ADU. If your budget tops out below $1.5M and you want an ADU property, you'll likely need to look at unpermitted units, look at Anaheim or Garden Grove, or consider building one yourself.
Price reductions are happening above $1.65M. Don't rush at full ask in the upper tier.
Income-producing duplex-style ADU properties (Citrus, Lime) are sitting longer than vacant move-in homes — meaning more leverage if you actually want a tenanted property.
My Take Going Into Late Spring
May should bring more inventory in Orange — sellers who held off through Q1 are starting to list. I'd expect:
One or two more AB 1033 conversations to start leaking into listings as San Diego County's separate-ADU-sale activation continues to ripple through California's high-equity ADU markets.
Continued price compression at the top ($1.8M+) as buyers in this band stretch their search across more cities.
A pickup in Old Towne ADU activity as Chapman summer break reduces showing friction in tenant-occupied properties.
If you have an Orange home with an ADU and you're planning to list in 2026, the best thing you can do this month is get a real, current valuation — not a Zillow estimate, a real one. Reply to this post or book a 15-minute call and I'll send you the comp set within 24 hours.
