Two weeks after an $8.7 million Hillsborough sale, a permit to add on to a 10,937-square-foot house
15 Boroughwood Place sold in May at 8.9% over asking, and a permit for a family-room addition was filed two weeks later. An interior deconstruction permit followed two weeks after that.
A 322-Square-Foot Addition To A 10,937-Square-Foot House
15 Boroughwood Place closed in May at 8.9% over asking. A permit for a family-room addition was filed two weeks later, and an interior deconstruction permit two weeks after that.
| Address | Closed | Price | House | Lot | Sale-to-List | DOM | Permits Filed Around The Sale | |---|---|---|---|---|---|---|---| | 15 Boroughwood Pl, Hillsborough | 2026-05-11 | $8,700,000 | 10,937 sf | 1.90 ac (82,603 sf) | 108.9% | 33 | Sewer video review, filed 5/6 | | | | | | | | | Two sewer lateral permits, $15,000 each, filed 5/13 | | | | | | | | | Addition with remodel, $638,000, filed 5/26, issued 8/6 | | | | | | | | | Demolition (dwelling), interior only, $30,000, filed 6/9, issued 8/6 |
The two larger permits are issued, not finaled, so the record does not show the work as complete, and it does not name the applicant. The town's description of the first is a family-room expansion adding 322.5 square feet with new coffered ceilings, filed under the permit class for an addition with remodel where total alterations exceed 1,000 square feet. The declared value is $638,000.
The second is filed under the town's dwelling-demolition class, but its description reads interior deconstruction only, with no structural work, and its declared value is $30,000. That points to finishes and interiors, not the frame of the house.
Large remodels are common in this town. Since January 2023 the permit record shows 108 major remodels or additions over 1,000 square feet in Hillsborough, alongside 46 primary-dwelling permits. For a sale followed by a demolition permit instead, see 172 Toyon Road, above.
46 days after a $7.5 million Atherton sale, a demolition permit was filed
172 Toyon Road closed in mid-May, and a demolition permit was filed for it on June 30, followed by two heritage tree removal permits. The permit does not say what is coming down.
What The Permit Record Shows 46 Days After A $7.5 Million Atherton Sale
A demolition permit was filed for 172 Toyon Road on June 30, forty-six days after the sale closed, and two heritage tree removal permits followed over the next two months.
| Address | Closed | Price | Lot | House | Permits Filed Since Close | |---|---|---|---|---|---| | 172 Toyon Rd, Atherton | 2026-05-15 | $7,527,000 | 1.32 ac (57,450 sf) | 5,240 sf | Plumbing, sewer, filed and issued 6/15 | | | | | | | Demo (Other), $60,000, filed 6/30, issued 9/11 | | | | | | | Heritage tree removal, filed 7/6, issued 7/9 | | | | | | | Heritage tree removal, filed 8/24, issued 8/28 |
One caveat on the headline permit: Atherton filed it under "Demo, Other," the town's catch-all code, not "Demo, Full Site," which is what it uses for whole-house teardowns. The declared value is $60,000. The record confirms something is scheduled to come down on the lot; it does not confirm the house is the something. The permit is issued, not finaled, so the record does not show the work as complete, and it does not name the applicant.
Demolition after a sale is common in this town. Since January 2023, the permit record shows 79 new-residence permits in Atherton carrying roughly $335 million in declared construction value, alongside 71 full-site or residence demolitions.
On the same street, a different sequence. 51 Toyon Rd sold eight months earlier, in September 2025, for $7,520,000 (nine days on market, 4.5% over asking) on a smaller lot, 0.90 acres against 172's 1.32. Two permits have since been issued there: a $1,247,500 remodel and addition, and a detached-garage alteration, both filed in March and issued in May.
Seven cities have less than a month of houses for sale. Four have more than two.
Burlingame, Sunnyvale, Belmont, San Mateo, San Carlos, Mountain View and Los Altos each ended September with less than a month of single-family supply, while Woodside, Atherton, East Palo Alto and Los Gatos are sitting on more than two months. Price is not what separates them: Woodside's houses sold about as far over asking as Burlingame's.

Fast is under 1 month of supply, slow is over 2. Cities with fewer than 8 active houses are left out because one listing would swing the ratio. * marks a city with 5 or fewer closings in the window, where one sale moves months of supply a lot; read those as directional. Recorded closings can trail by a few days, so the newest closings may still be arriving.

Which San Mateo Peninsula cities does AddressIntel cover?
AddressIntel tracks the full Peninsula corridor, including Atherton, Burlingame, Hillsborough, Menlo Park, Palo Alto, Redwood City, San Carlos, San Mateo, Woodside, and more, with live listings, sales, and permit data for each city.
How does AddressIntel predict teardowns on the Peninsula?
Each property is scored on lot value relative to structure value, building age, and recent neighborhood comps. High land-to-improvement ratios in markets like Atherton and Palo Alto flag the strongest teardown and rebuild candidates.
Where does the Peninsula permit data come from?
Building, addition, and demolition permits are pulled directly from city building-department systems (Accela, eTRAKiT and Tyler EnerGov) and refreshed daily, so you can spot new construction and demolition activity as it is filed. Coverage is per city rather than Peninsula-wide: the cities we ingest are listed on the permit tracker, and each city dashboard says plainly whether we carry that city or link you to its own portal instead.
Can I see developer ROI for Peninsula properties?
Yes. AddressIntel projects per-property developer ROI from land cost, build spec, and local comps, helping you compare opportunities across Peninsula submarkets.
