At 404 and 406 Ridge Avenue, a property owner asked the village to merge two lots into one. The existing house stays where it is, and the second parcel stays open. At the February 5, 2026 Plan Commission meeting, Commissioner DeLongis said that neighbors had asked the owner not to build another house there, and that they appreciated the open space he was leaving. The commission approved the consolidation 5–0.
A lot that could have held a second house now holds none. That fits the rest of the village's 2026 permit record. Buyers who arrive expecting a teardown market like the ones in neighboring suburbs find something different. Clarendon Hills is expanding the houses it already has, holding new detached construction to a few custom builds, and moving its new supply into downtown multifamily projects that take years to finish.
Five Houses in Eight Months
The village's monthly building permit report for August 2026 shows five new single-family permits for the year through August, with a combined construction value of $5,050,000. Through August 2025 the count was also five, valued at $5,700,000. The pace is flat, and five houses in eight months is a thin pipeline for a village in this price range.
The ledger lists each of them:
- 153 Norfolk, demo and new construction, Collins Sarsfield Construction, $600,000, issued March 23
- 153 Juliet, new construction, Sun Construction Building Corp, $850,000, issued May 1
- 362 Western, Lot 2, new construction, Uthon Builders, $1,200,000, issued May 5
- 363 Ruby, demo and new construction, Oakley Home Builders, $1,400,000, issued May 15
- 2 Arthur, new construction, KM Homes, $1,000,000, the single new-home permit issued in August
Only two of the five are recorded as a demolition followed by a new house. The summary table's standalone "Demolition" line shows no single-family demolitions so far in 2026, compared with one through August 2025. The two teardowns were filed as combined demo/new permits instead. One of those two sites was not a conventional house lot. In July 2025 the Village Board rezoned 153 Norfolk from public/institutional to R-1 so the church-owned property could go back to single-family use and support a new home.
Those dollar figures are construction valuations filed with the permit. They are not sale prices, and they leave out the land.
The Addition Permits Tell a Different Story
The same report puts the single-family addition and remodel category at 37 permits worth $4,034,397 through August 2026. Through August 2025 it was 27 permits worth $3,589,490. New houses held at five while additions and remodels rose by ten.
Some of those permits are large. On May 7, McCarron Custom Homes pulled a "Residential Expansion" permit at 114 S. Prospect valued at $820,000, which is more than the $600,000 demo-and-rebuild at 153 Norfolk. Bradford & Kent filed a $280,000 expansion at 33 Arthur. REBLD General Contracting filed a $175,000 addition at 132 Mohawk.
For a buyer, this changes what the "updated home" listings in Clarendon Hills are likely to be. Many of the larger, more modern-feeling houses on the market will be older homes that have been expanded. Few will be ground-up builds. Inspections, permit history and questions about how old the original structure is weigh more heavily on those houses than on a new build.
Three Village Decisions Affecting New Houses
The village has not banned teardowns. Several village decisions affect the process of building a new house.
- Stormwater on every new house. In April 2025 the Village Board amended its stormwater rules so that every new single-family residence must include post-construction best management practices, however small the disturbed area.
- A higher extension fee for longer builds. The board raised the extension fee on new single-family building permits from one-third to three-quarters of the original permit fee. The change was proposed in July 2025 after complaints about builds running more than a year, and adopted on August 18, 2025.
- Open space kept as open space. The 404–406 Ridge consolidation turned two buildable parcels into one lot with one house.
Each of these affects a buyer directly. If you're buying a spec house still under construction, or hiring a builder for a lot you've bought, ask for the permit issue date and the builder's schedule in writing. A build that runs long now carries a fee that is more than twice as large as the old one. If you're buying a finished new home, the stormwater features on the lot are required by code and are part of what you're paying for.
Where the New Units Actually Are
Most of the new housing in Clarendon Hills is downtown, and it is attached. The permit report shows one new multifamily permit in 2026, valued at $3,000,000. That permit is the six townhomes at 421 Park Units ABC and 423 Park, issued to Tranquility Builders on February 9. Those six townhomes are more units than all five new single-family permits combined.
| Project | Developer | Units | Status as of September 2026 | Village's timing |
|---|---|---|---|---|
| 421/423 Park Avenue | Tranquility Builders | 6 townhomes | Under construction; walls for Building 2 going up as of July 17 | "Fall of this year" in a March report; "2026/27" in the village's project roundup |
| Parkside Place, 104 Walker / 301 Park | Redwood Construction Group | Reported as 16, 17 or 18 condos, depending on the source | Approved September 2025; village attorney coordinating the land closing in September 2026 | Grading was targeted for Spring 2026; completion anticipated in 2028 |
| 136 Burlington Avenue | MC Development | 6 condos plus retail | Variance hearing continued to October 1, 2026 | None set |
The village describes the 421 Park units as luxury townhomes designed without basements, built on the site of an older building, with stormwater improvements for the surrounding area. No asking prices have been published.
Parkside Place is the largest project in the pipeline, and it is behind the schedule in the village's own roundup. The Village Board approved it on September 15, 2025. Patch reported the vote as 5–1 after a contentious meeting. The report said residents who spoke against it raised concerns about scale, traffic, safety near Walker School, stormwater and neighborhood character, while the Chamber of Commerce supported it. The village's roundup describes the approved building as four stories with 18 condominiums, 2,400 square feet of retail, 1,000 square feet of office space and a 38-space indoor garage. It says grading would start in Spring 2026 and construction would take about two years. The village's September 18, 2026 weekly report says the Village Attorney is coordinating the closing on 104 Walker and 301 Park this month. If grading hasn't started by fall, a 2028 completion depends on a two-year build starting soon.
The only prices tied to Parkside Place are the developer's estimates from the August 2025 hearing: one-bedrooms in the high $600,000s and three-bedrooms starting at $1.5 million. Those estimates were for an earlier design that included a boutique hotel, which the zoning board rejected. They are not current asking prices.
At 136 Burlington, MC Development, headed by Tommy Maguire, wants to build a four-story building with six condos over first-floor retail. The site faces the railroad tracks, and the existing building houses Collins Sarsfield Construction and Builders Heating and Cooling. The developer is asking for 50 feet of height, where the village limit is 40. Village staff asked for preliminary engineering plans early so neighbors' stormwater concerns could be addressed. The September 3 hearing drew what the village called significant testimony and discussion, and it was continued to the October 1 meeting of the Zoning Board of Appeals/Plan Commission.
How This Plays Out at the Offer Table
Village-level data from the Illinois REALTORS reports isn't publicly available for Clarendon Hills, so the county figures are the backdrop. In August 2026, DuPage County had 1,415 homes for sale, up 6.6% from August 2025, and homes took a median of 19 days to sell, compared with 17 a year earlier. The countywide median sale price was $450,000, up 4.7%. By property type, the August single-family median was $553,500 and the condo median was $306,000. Mainstreet REALTORS reported that Chicagoland had 2 months of supply in July 2026.
Countywide, inventory is loosening a little. Clarendon Hills adds very little new supply of its own, so the loosening there comes almost entirely from resale listings. Here is how that sorts out by buyer:
If you want a new detached house, your realistic options are the few custom builds that come up each year, and you'll compete for them directly. Ask who the builder is, when the permit was issued and how far along the stormwater work is.
If you want space and modern finishes, you'll mostly be looking at expanded older homes. Pull the permit history and confirm that the addition was permitted and closed out.
If you want new construction without a yard to maintain, look at the downtown projects. The 421 Park townhomes are the nearest to finished. Parkside Place is still waiting on its land closing, and 136 Burlington is still waiting on a variance decision.
If you're selling an older home on a standard lot, your buyers include people planning an expansion as well as teardown builders. The 2026 permits show expansion is currently the more active path.
FAQ
Are the permit values what these new homes will sell for? No. Permit values are the construction costs builders declare to the village. They leave out land, and they aren't sale prices.
When will Parkside Place be finished? The village's roundup says 2028 and assumes a two-year build. As of September 18, 2026, the land closing was still being coordinated, and no groundbreaking had been reported.
Has 136 Burlington been approved? Not as of September 23, 2026. The zoning hearing was continued to October 1, and the Village Board has not considered the project.
