Santa Ana ADU Properties — Market Update (April 2026)
Santa Ana is one of the most active ADU markets in all of Orange County — and it's not even close. With a combination of affordable lot sizes, investor-friendly zoning, and proximity to major employment centers, this city consistently produces more ADU listings than most of its neighbors combined. This month's data confirms it: 12 total ADU properties across active, pending, and under-contract status, spanning a price range from $799,000 to $3.495 million.

If you're an owner, investor, or seller with an ADU property in Santa Ana, here's exactly what the market looks like right now.
What's Active Right Now: 8 ADU Listings
There are currently eight ADU properties actively listed in Santa Ana, plus one coming soon. The diversity here is striking — everything from a $799K starter with ADU plans to a $3.495M Spanish estate in the North Tustin foothills.
2521 W Stanford St, Santa Ana 92704 — $799,000 (Price Reduced) This is the most affordable ADU listing in Santa Ana right now, reduced from $829,000 on April 7. The main home is a 2-bed, 1-bath at 748 square feet on a 5,220-square-foot lot. The detached garage includes ADU plans — 1 bed, 1 bath — but the unit is not yet built. The listing emphasizes "ADU potential with the city," so buyers will need to verify permits and plans independently. At $1,068 per square foot for the existing home, the value proposition here is really about the lot and the ADU upside. It's been on market for 10 days with an open house on April 12. If you're evaluating properties like this, checking the comps before you build is essential — an unbuilt ADU adds uncertainty that buyers will price in.
408 S Flower St, Santa Ana 92703 — $1,049,900 (Price Reduced) This property has been on market for 350 days and has seen significant price cuts — originally listed at $1,250,000. The main home is 3 beds, 1 bath, 1,148 square feet, fully remodeled with vinyl flooring, quartz countertops, and recessed lighting. The detached ADU is 574 square feet, 1 bed and 2 baths, built in 2021 by a builder, with garage access, separate electric meter, and its own address. At $609.70 per square foot across the combined 1,722 square feet, this one has been sitting despite multiple reductions. The extended days on market pattern is something we're seeing across several Santa Ana ADU listings this month.
1246 S Baker St, Santa Ana 92707 — $1,245,000 (Price Reduced) Another long-sitting listing at 343 days on market, reduced from $1,345,000 on April 9. The main home is 3 beds, 2 baths, and the detached ADU is 1,000 square feet — 2 beds, 2 baths, built in 2023, with separate electric meter, separate gas meter, and separate water meter. The ADU is currently rented at $3,350 per month, and total rental income across both units is $6,650 per month. The property also has paid-off solar and green building verification. At $590.89 per square foot, the income numbers are strong, but the pricing still hasn't found a buyer after nearly a year. Located near Mater Dei High School in the Santa Ana ADU development zone, this property demonstrates how even strong rental income doesn't always translate to quick sales when the ask price is too high relative to comps.
2302 W La Verne Ave, Santa Ana 92704 — $1,249,999 This property has been on market for 130 days. The main home is 3 beds, 2 baths, with a detached ADU of approximately 800 square feet — 2 beds, 2 baths, built in 2021, currently rented at $3,000 per month with separate electric and gas meters. The lot is over 7,300 square feet with paid-off solar. At $683.81 per square foot, the pricing is competitive for the area. The property is sold as-is with tenants in month-to-month leases. If you're dealing with a similar situation, showing an ADU property while tenants are in place requires a specific strategy that many sellers overlook.
1411 W 7th St, Santa Ana 92703 — $1,375,000 (NEW) Brand new to market as of April 1. This is a true two-homes-on-one-lot setup with brand-new construction. The remodeled main home is a 3-bed, 2-bath at approximately 991 square feet, rented at $3,590 per month. The brand-new detached ADU is 990 square feet — 3 beds, 2 baths, built in 2026 — rented at $3,650 per month. Total rental income is $7,240 per month. Both units have tenants paying all utilities. At $694.09 per square foot across 1,981 combined square feet, this is one of the strongest income plays in the entire Santa Ana market right now. The 990-square-foot ADU is one of the largest new-construction units across all current listings.
4721 W Oakfield, Santa Ana 92703 — $1,680,000 (Price Reduced) This is the only three-unit setup in the current Santa Ana ADU inventory. The main home is approximately 1,143 square feet with 3 beds and 2 baths, plus an attached JADU of approximately 500 square feet (1 bed, 1 bath, built 2025, rented at $2,000/month), plus a detached ADU of approximately 800 square feet (2 beds, 2 baths, built 2025, rented at $2,900/month). Total rental income: $8,500 per month. All three units have their own addresses and are separated by fencing. The property has paid-off solar and 2 water meters, 2 electrical meters, and 1 gas meter. At $687.68 per square foot, it's been on market for 45 days. The combination of a JADU and a detached ADU on a single lot maximizes both income and Fannie Mae lending flexibility.
13081 Prospect, Santa Ana 92705 — $2,690,000 (Coming Soon) This North Tustin property doesn't start showings until April 28. It's a 4-bed, 4-bath home at 2,100 square feet on a half-acre lot with a pool, RV parking, and a batting cage. The ADU is a modest 250 square feet — 1 bed, 1 bath, built in 1948, located in what appears to be a converted structure. At $1,280.95 per square foot, the value here is really about the land and the North Tustin location. The ADU is the smallest across all current Santa Ana listings. DAM: 0 (not yet on market).
2240 Foothill Blvd, Santa Ana 92705 — $3,495,000 (Price Reduced) The priciest ADU listing in Santa Ana this month. This Spanish-style custom home in the North Tustin foothills has been on market for 340 days, reduced from $3,695,000. The main home is 3,496 square feet, 3 beds, 3 baths and a half bath across three levels. The casita/ADU in the backyard is approximately 400 square feet with a full bathroom and kitchenette. At $999.71 per square foot, this is a luxury play where the ADU is an afterthought — similar to what we see in high-end markets across Orange County where the ADU adds value but doesn't drive the purchase decision.
Active Listings: ADU Size Breakdown
The ADU sizes across active Santa Ana listings vary dramatically:
Plans only (no built unit) — 2521 W Stanford
250 sqft — 13081 Prospect (1948 conversion)
400 sqft — 2240 Foothill (casita)
500 sqft JADU + 800 sqft ADU — 4721 W Oakfield (dual unit, both 2025)
574 sqft — 408 S Flower (2021 build)
800 sqft — 2302 W La Verne (2021 build)
990 sqft — 1411 W 7th (2026 new construction)
1,000 sqft — 1246 S Baker (2023 build)
The trend is clear: newer ADUs in Santa Ana are being built larger. Every ADU constructed after 2021 in this dataset is 750 square feet or above, pushing toward the California state maximum of 1,200 square feet for detached units. The 2025 and 2026 builds are coming in at 800–990 square feet with full kitchens, separate meters, and 2+ bedrooms — these are real rental units, not afterthought guest quarters.
Pending and Under Contract: 4 Properties
Four ADU properties in Santa Ana are currently pending or under contract, and the data here tells a powerful story about where demand is concentrated.
614 N Shelton, Santa Ana 92703 — $849,000 (Pending) The fastest mover this month. This property went pending in just 6 days. The main home is 3 beds, 1 bath, and the detached ADU is 750 square feet — 2 beds, 1 bath, newly built in 2024 with its own private entrance, solar, and washer/dryer hookups. At $524.07 per square foot across 1,620 combined square feet, it was the most affordable completed-ADU property in Santa Ana. Both units will be delivered vacant at closing. The 6-day pending speed confirms what the data keeps showing — priced-right ADU properties under $900K are getting immediate buyer attention.
928 S Laurel St, Santa Ana 92704 — $1,100,000 (Pending) This fully remodeled property went pending in 20 days. The main home is 4 beds, 2 baths, and the attached Junior ADU is 356 square feet — 1 bed, 1 bath, with its own private entrance and full kitchen. At $668.29 per square foot, it closed at its asking price of $1,100,000. The JADU is the smallest completed unit across all pending sales this month, but the full remodel and move-in condition drove the quick sale.
12831 Fairhaven Extension, Santa Ana 92705 — $2,100,000 (Under Contract) This North Tustin property went under contract in 30 days at its asking price. The main home is 4 beds, 3.5 baths at 3,165 square feet on nearly half an acre with a circular driveway, RV parking, and a 3-car garage. The detached casita/ADU is approximately 470 square feet with 1 bed and 1 bath. At $663.51 per square foot, this was priced well for the North Tustin area. Contract date: March 23, 2026.
122 N Bewley St, Santa Ana 92703 — $1,275,000 (Pending) This property went pending after 32 days on market. It's a fully renovated main home at 1,551 square feet with 4 beds and 2.5 baths, plus a newly constructed detached ADU of 783 square feet — 2 beds, 1 bath. The ADU features an open-concept layout with a new kitchen, mini-split HVAC, and in-unit laundry. At $545.80 per square foot across 2,336 combined square feet, the value here is strong. Both units delivered vacant at closing with parking for up to four cars.
Pending Sales: Days on Market
614 N Shelton — 6 days to pending
928 S Laurel — 20 days to pending
12831 Fairhaven Ext — 30 days to under contract
122 N Bewley — 32 days to pending
Average days to pending: 22 days. Compare that to the active listings, where four properties have been sitting for over 130 days — and three of those for over 340 days. The gap between well-priced and overpriced ADU properties in Santa Ana is wider than in almost any other Orange County city.
What This Data Tells Us
Santa Ana has a two-speed market. Properties priced under $1.3 million with completed, permitted ADUs are moving in under 32 days. Properties priced above $1.3 million or with extended days on market are struggling — three active listings have been sitting for 340+ days. The pricing sweet spot for Santa Ana ADU properties is $849K–$1.275M, which is where all four pending sales fell.
Rental income is strong but doesn't guarantee a quick sale. The Baker Street property generates $6,650/month and has been sitting for 343 days. The Oakfield property generates $8,500/month and has been listed for 45 days. Meanwhile, 614 N Shelton went pending in 6 days at $849K with no tenants in place — delivered vacant. Buyers in Santa Ana want flexibility, not inherited tenants, unless the price reflects a true investment return. The markets in Anaheim and Buena Park show similar patterns — income potential matters, but entry price matters more.
New construction ADUs are getting bigger. The 2025 and 2026 ADU builds in this dataset average 860 square feet with 2+ bedrooms, separate meters, and full kitchens. The City of Santa Ana's ADU development standards support this trend, and it's producing units that function as genuine standalone rentals. This is a meaningful shift from the 250–500 square foot conversions and casitas that dominated earlier inventory.
North Tustin is a different game. The three highest-priced listings — Prospect ($2.69M), Fairhaven ($2.1M), and Foothill ($3.495M) — are all in the North Tustin area with Santa Ana addresses. These properties compete with Tustin proper and the Orange Park Acres equestrian market. The ADUs here are smaller (250–470 sqft) and secondary to the land, views, and lifestyle. Fairhaven went under contract at 30 days, while Foothill has been sitting at 340 days — price discipline matters even at the luxury end.
Detached ADUs dominate. Nine of the twelve total listings feature detached ADUs or casitas. Only two have Junior ADUs (Oakfield's attached JADU and Laurel's attached JADU). The market strongly favors detached units with separate entrances and meters, which is consistent with what we're seeing across Costa Mesa, Long Beach, and the rest of Orange County.
Bottom Line for Santa Ana ADU Sellers
Santa Ana is one of the deepest ADU markets in Orange County, but depth cuts both ways. There's real demand — four properties went pending this month, all within 32 days — but there's also significant stale inventory, with three listings past 340 days on market.
The data is clear on what moves: permitted ADUs, completed construction, a price point under $1.3M, and either vacant delivery or strong income documentation. If you're above $1.3M, expect longer marketing times and at least one price adjustment.
