Why Garden City's Home Prices Don't Agree With Each Other Right Now

Pull three different sources for Garden City home values this year and you get three different stories. Redfin has the median sale price at $532,681 as of May 2026, down 15.3 percent from a year earlier. Zillow's home value index puts the average closer to $474,544 as of April 2026, down a more modest 1.7 percent. Listing-side data from earlier in the summer put asking prices in the $750,000 to $830,000 range, depending on whether condos were included. These aren't rounding errors or methodology quirks you can wave away. They're symptoms of a city that is, at this exact moment, being rezoned in two opposite directions at once.

Garden City is a thin strip of land wedged along the Boise River, surrounded by Boise on three sides, with its own city hall, its own comprehensive plan, and its own council making block-by-block decisions that are pulling the place apart in two different ways. Near the river, the city is actively working to add height and density. A few streets inland, it's doing the reverse. If you're comparing Garden City to Boise or Eagle right now, the median price isn't the useful number. The zoning map is.

The Riverfront Plan That Would Add Height

The most consequential thing happening in Garden City real estate right now involves land that isn't even developed yet. For years, an 11-acre Ada County Highway District maintenance yard has sat on prime riverfront ground near Heron Park, tied up because ACHD needed it for equipment storage. The agency agreed to relocate that operation, and the city has spent 2026 building a plan for what replaces it.

That plan now covers roughly 34 acres between Heron Park, Waterfront Park, and Clay Street, and the city is calling it the Heron Commons Specific Area Plan. The draft ordinance under discussion splits the area into three subdistricts: a Public Interface zone closest to the greenbelt with development capped at 40 percent lot coverage, a Residential Edge zone meant to buffer existing neighbors, and a Mixed Use Residential zone allowed to include commercial and cultural space alongside housing. Buildings near the greenbelt-facing subdistricts would be capped at four stories, but elsewhere in the plan area, six stories would be allowed. For comparison, the neighboring Waterfront District, an existing 17-acre development of single-family homes, townhomes, live-work units, and riverfront condos, was already zoned for buildings up to 72 feet.

City staff and consultants held a neighborhood meeting on the Adams Street portion of this plan in April 2026, followed by hearings in May and July. It didn't go smoothly. At the May hearing, longtime Garden City resident Nancy Baskin told the council:

"This is a generational project and a chance for development to be done right, similar to the Waterfront District that has changed Garden City. So, slow down."

Other residents pushed back specifically on a proposed connector linking two disconnected segments of Adams Street, worried it would route car traffic through a currently quiet neighborhood and add to congestion already building near the 36th Street bridge. Resident David Twyver put it bluntly at the same hearing: there was, in his view, no good reason to allow that connection to become a car passage rather than a path reserved for cyclists, pedestrians, and emergency vehicles.

By late May, city staff had responded by floating a hybrid Option C, essentially trying to keep the flexibility of the mixed-use zoning while adding more objective design standards for the sensitive edge areas. As of this writing, no final ordinance had been adopted. That matters for a buyer: land inside this footprint carries real upside if the plan lands close to the current draft, but it's still upside tied to an ordinance that hasn't cleared council.

A Few Streets Over, City Hall Is Doing the Opposite

While the riverfront gets more room to grow, the city has spent the same stretch of 2026 quietly reducing what's allowed on established residential streets elsewhere in town. In 2025, Garden City adopted Ordinance 1057-25, creating a new Medium Density Residential zone, called R-M, following a 2024 comprehensive plan amendment. On its face, adding a new zoning category sounds like more flexibility. In practice, the city has been using R-M to pull density down, not up.

Look at the parcels on Strawberry Glenn Road. That property is being rezoned from R-3, which allows up to 35 dwelling units per acre with no height cap, down to R-2, which caps density at 6 units per acre (with an exception up to 20 units per acre only inside a designated Activity Node) and limits building height to 35 feet. Front setbacks are growing from 5 feet to 15 feet, streetside setbacks from 5 feet to 20 feet. City planning documents describe this plainly as a down-zone. A separate rezone affecting property on Marigold Street moves it from R-3 to R-M, cutting allowed density from 35 units per acre to 15.

These aren't fringe parcels nobody cares about. They're the kind of established, single-family blocks that make up most of residential Garden City, the parts of the city that don't show up in press coverage about mixed-use redevelopment because nothing dramatic is being built there. The city is deliberately protecting them from the kind of higher-density change it's simultaneously inviting a half mile away, near the river.

Two Zoning Tracks, Compared

What This Means When You're Comparing Listings

If you're shopping Garden City against Boise or Eagle right now, the first question worth asking about any specific address is which of these two tracks it sits on, not just how close it is to the greenbelt. A property inside or adjacent to the Heron Commons plan area is a bet on a specific ordinance that's still being negotiated. A property on a street that just got down-zoned to R-2 is closer to a known quantity: the neighborhood around it is now legally protected from turning into something taller or denser than what's already there.

This is also the simplest explanation for why Redfin, Zillow, and list-price data disagree by tens of thousands of dollars on what a "typical" Garden City home costs. Garden City had roughly 120 active listings across the entire city in mid-2026, a small enough sample that a few new-construction units near the Waterfront District or a cluster of older homes near an industrial parcel can swing a median hard in either direction, month to month. Add a city that is actively rezoning parcel by parcel in opposite directions, and a single median stops being a meaningful number. The dispersion in the data isn't noise. It's two different housing stocks, sitting a few blocks apart, being priced by two different sets of rules.

For a buyer this means the homework changes. Don't just ask what a home last sold for. Ask whether the parcel sits inside a pending Specific Area Plan boundary, whether it was recently rezoned under Ordinance 1057-25, and whether the block next door is protected R-2 or open to future mixed-use. The city's Development Services Department tracks all of this through its FY2026 applications log, and it's public record.

FAQ

Does this affect a home I already own in Garden City? Only if your parcel is inside one of the areas actually being rezoned. The Heron Commons plan and the R-M down-zones each apply to specific, named parcels, not the city as a whole. Checking your address against the city's current zoning applications is the only way to know for certain.

Is the Heron Commons plan a done deal? No. As of the most recent hearings, the city was still weighing a hybrid approach after resident concerns about traffic and building height near the greenbelt. Anyone buying on the assumption that six-story mixed-use is coming to a specific parcel should confirm the ordinance has actually been adopted, not just proposed.

Why would a city down-zone land it just created a new residential category for? Ordinance 1057-25 created the R-M zone as a flexible tool. City staff have applied it, along with a shift to R-2, on specific parcels where neighbors and the comprehensive plan called for less intensity than the old R-3 zoning allowed. The new zone gave the city a middle option between the old high-density R-3 and the strictest single-family zoning.
