Santa Ana ADU Homes for Sale — Prices, Rents & Closed Sales (September 2026)
If you're shopping for a home with an ADU in Santa Ana right now, the market is giving you more to work with than it has in years. Thirteen active listings, a brand-new batch of 2025 and 2026-built ADUs, and rents pushing past $3,600 a month on the top end. One home even closed in late August — and it went under contract fast enough that you'll want to know why.
This post pulls directly from MLS data printed on September 3, 2026. Every property here carries an ADU or JADU disclosure. Prices, rents, and unit details come straight from the listing sheets.
What's for Sale Right Now
Under $1,000,000
512 S Maple, Santa Ana 92701 — $899,000 A fully remodeled, delivered-vacant duplex in the South of First corridor. The main house is 2 bedrooms, 1 bath with newly constructed, permitted attached ADU — 2 bedrooms, 1 bath, 424 sq ft, built 2025. Both units were gut-renovated together, with Saltillo tile, quartz countertops, and upgraded fixtures throughout. The listing notes two separate electrical systems. Priced down from $929,000 in August. The ADU isn't yet rented, so a buyer steps in to set the rent from day one. List price: $899,000.
1926 W 18th St, Santa Ana 92706 — $900,000 (Coming Soon — Showings Begin Sept. 10) A 3-bedroom, 2-bath main house at 854 sq ft in the North of First area, carrying a Junior ADU disclosure. Attached, at street level, shared meter. No rent history listed — the ADU appears to function as an attached unit within the main footprint. Lot is 6,025 sq ft. List price: $900,000.
1922 Meriday, Santa Ana 92706 — $945,000 A recently remodeled single-story, 3 bedroom, 2 bath home in North Santa Ana sitting on a generous 6,324-square-foot lot. The listing description notes potential for ADU and JADU development — buyer to verify with the city. No existing ADU is reflected in the MLS. A buyer willing to build gets a turnkey main house and the chance to add units on a lot that the agent confirms is eligible for development. Priced down from $960,000. List price: $945,000.

The ADU is already leased at $3,650/month through April 2027. Main house rents at $3,590/month through the same period. Total combined income: $7,240/month.

Under Contract
1050 W Chestnut Ave, Santa Ana 92703 — $1,295,000 This one went under contract on August 25, 2026 — and it's easy to see why. A brand-new 2026 ADU (2 bedrooms, 1 bath, 1,000 sq ft) sits behind a fully rebuilt and remodeled 3-bedroom, 2-bath front house on an 8,400+ sq ft lot. Combined living space: 2,016 sq ft. The rear ADU features 9-foot ceilings, ductless heating and cooling, and paid-off solar. RV access and parking for up to 10 vehicles. Two separate units, two separate incomes, turnkey condition. It was back on market as of July 30 — and was gone within 26 days. Contract price: $1,295,000.
Closed Sales
1205 S Flower, Santa Ana 92707 — Sold $955,000 (Closed Aug. 26, 2026) A 2-bedroom, 1-bath main bungalow (901 sq ft) with a detached 1-bedroom, 1-bath ADU (400 sq ft) in the Wilshire Square neighborhood, just 7–10 minutes from Downtown Santa Ana and South Coast Plaza. The listing noted a Walk Score of 74, solar panels, and a low-maintenance backyard. Originally listed at $999,000, it entered escrow and closed at $955,000 — 4.4% under list. The buyer financed conventionally. Seller paid $19,100 in concessions toward buyer costs. One data point, but a useful one: buyers are still finding room to negotiate in Santa Ana's ADU market.

Rent per square foot on detached units ranges from roughly $3.20 to $4.20/sq ft/month, with newer 2025–2026 builds commanding the top of that range. A fully permitted 2-bedroom, 2-bath ADU in the 800–1,000 sq ft range is generating between $2,600 and $3,650 a month, depending on finishes, location, and utilities structure.
What the Data Tells You
New construction ADUs are everywhere. Of the 13 active listings, at least five feature ADUs built in 2025 or 2026. Santa Ana's permitting pipeline has been active, and sellers are bringing inventory to market while rents and values are elevated. If you're buying a home with a new ADU, you're getting a unit that doesn't need capital for years.
The $999K–$1.1M band is the most competitive entry point. Four active listings sit in that range, each with a detached or attached ADU that's either newly built or recently upgraded. This is where most ADU buyers will focus — and where sellers have already started trimming prices (512 S Maple down from $929K, 2031 S Center down from $1.14M).
Three-bedroom ADUs are rare and worth paying attention to. The 1411 W 7th property is the only listing in the city right now with a 3-bedroom detached ADU. At 990 sq ft and $3,650/month in rent, it represents the ceiling of what the Santa Ana ADU rental market is currently pricing in. Watch that lease closely — it runs through April 2027, meaning a buyer inherits a locked-in income stream.
Sellers are conceding. The only closed sale in August came in 4.4% under list, with the seller covering nearly $20,000 in buyer closing costs. Buyers who come in prepared with pre-approval and a clean offer have leverage — especially on properties that have been sitting since spring.
Santa Ana's ADU rules make it one of the most builder-friendly cities in Orange County. The city has pre-approved ADU plan sets available through the Planning Division, which can cut months off a permitting timeline for owners who want to add a unit after purchase. You can review the City of Santa Ana's ADU development standards before you start planning. The Santa Ana ADU FAQs page covers setbacks, size limits, and owner-occupancy rules — worth reading before you make an offer on a lot where you're counting on adding a second unit.
Thinking About Selling Your Santa Ana Home with an ADU?
If you own an ADU property in Santa Ana and are watching the market, September is a meaningful moment. Inventory is elevated compared to a year ago, but the buyers showing up are serious — they're specifically seeking income properties and aren't wasting time on homes that don't pencil out.
A few things that differentiate listings that sell quickly from those that sit:
Rented ADUs with documented leases close faster. Buyers can underwrite the income from day one.
Delivered-vacant properties with turnkey condition also move — buyers who want to set their own rents prefer not inheriting old tenancies.
Homes with unpermitted ADUs are a harder sell right now. Understanding how AB 2533 amnesty works — for both buyers and sellers — matters more than it did two years ago.
If you're weighing your options, the complete seller's guide for ADU homes walks through how ADU income is disclosed, how appraisers handle it, and what buyers are actually looking for.
Buyers: What You Need to Know Before You Offer
Santa Ana sits at an interesting intersection of affordability (relative to coastal OC), strong rental demand, and permitting-friendly ADU policy. A few things to keep in mind as you evaluate properties here:
Verify ADU permits before you make an offer. Several listings in this batch note that MLS data is deemed reliable but not guaranteed — that's code for "pull the permits yourself." The city's pre-approved ADU plans program only helps for new builds; existing units need their own permit history verified.
Understand how lenders treat ADU rental income. Not all lenders count ADU rent the same way. Fannie Mae updated its guidelines in 2023 to allow rental income from ADUs on owner-occupied purchases — but the property and documentation need to meet specific criteria. This matters for how much house you can qualify for.
If you're buying to expand later, check the lot. Santa Ana allows one Standard ADU plus one JADU per single-family lot — and if you're looking at a lot with nothing built yet, the buyer's guide to finding ADU-potential lots in Orange County explains exactly what to look for in the county's parcel data before you write an offer.
Compare against nearby markets. ADU pricing in Santa Ana looks different from what you'd find in Garden Grove, Anaheim, or Fountain Valley. For a broader sense of how Orange County's ADU market is behaving, California's multi-unit ADU rule breakdown gives useful context on what state law allows across different property types.
