Beyder&Co. Realty · Alpine, New Jersey
Alpine, NJ homes and estates, on and off the market.
Beyder&Co. Realty advises buyers and sellers across Alpine’s estates and acreage on the Palisades — senior-led advisory, private-market intelligence, and discretion in every sale.
Alpine Market
Some of Alpine’s finest homes change hands before they are listed.
Alpine sits at the top of the Palisades, above parkland along the Hudson, with homes set far back on large, wooded lots. Some sales here happen before or instead of a public listing; Beyder&Co. Realty works these pre-market and off-market opportunities directly — matching qualified buyers to estates before they are ever advertised.
Buyers
Access to pre-market and off-market Alpine estates — not just what is publicly listed.
Understand how an off-market sale works and what a New Jersey buyer pays at closing.
Sellers
Discreet positioning and senior-only execution for sellers who prefer a quiet sale to a sign on the lawn.
Begin with how a home is valued and the costs of a New Jersey sale, then discuss your Alpine property.
Builders
Parcel intelligence and design-aware positioning for acreage, tear-downs, and new-construction opportunities. Buying a lot to build new? What to establish before you buy.
Published Alpine Work
The purchase. The work ahead.
In reporting published January 24, 2020, Realtor.com described Igor Beyder’s work on an Alpine home sale: gathering repair estimates so prospective buyers could consider the work alongside the purchase.
Before a decision
What records should I bring to an Alpine property discussion?
Alpine’s current Building Department page separates construction, zoning, drainage and septic questions. It directs septic matters to the Health Department and seepage-pit and drainage inspections to the Borough Engineer; the Construction Official and Zoning Official are available by appointment. A building inspection alone does not resolve every site question. Bring the survey, existing permits and proposed scope to the relevant office.
The published Alpine example above illustrates the value of separating purchase price from repair scope. Use the home-inspection guide to understand that report’s limits, then compare the property through the valuation guide. Add property taxes and buyer closing costs to the ownership budget, and check the actual route in the commute guide rather than assuming a journey time.
46 Overlook Road, Alpine · Purchase, renovation and sale case study
From purchase through a full gut renovation to sale.
The 46 Overlook Road project began with the purchase of the home, followed by a full gut renovation designed and built by B&Co. Design | Build. Beyder&Co. Realty then marketed and sold the renovated home. The completed residence has an opened single-level plan, vaulted ceilings and a walk-out lower level. Separate studies for future garden structures remain proposals.
The sequence brings acquisition, design, construction and brokerage into the same project while keeping their roles clear. The completed gut renovation is part of this home’s record; future garden studies describe additional possibilities. Those proposals need their own scope and Borough approvals, separate from the valuation and ownership budget for the residence as it stands.
Before considering the next project.
Questions this documented example can help you frame for your own property:
- Read the existing-condition photographs alongside the primary-suite drawing. Keep the separate future garden studies labeled as proposals.
- Use the residence as it stands for the valuation conversation; define any additional construction as a separate scope and budget.
- Bring that proposed scope and the property’s records to the Borough before relying on a future layout.
Other Alpine commissions in the Journal compare different scopes: Building 23 Church Street follows a ground-up design-build commission; The Berkery Place Commission considers design without construction.

Reading Alpine
The setting. The building. The next chapter.
Begin with the particular address: the bus routes that list Alpine, the building as it stands, and the changes being considered. These are useful starting points for a purchase, a sale or a renovation conversation.
Connection
Coach USA’s Rockland Coaches lists Alpine on its Route 9, 9A, 9T and 9TA line to the Port Authority and GW bus terminals, and on its Route 9W line to the Port Authority. The Borough notes that no overnight parking is allowed on Borough streets.
Context
The Borough publishes its Zoning Map as a downloadable PDF, and the Planning Board posts its meeting agendas and minutes. Use those records to place an address in context before deciding what to retain, change or add.
Possibility
A renovation begins with the existing building and a clear scope. Alpine’s Building Department lists the UCC construction permit application and the technical sections it requires, and its Zoning Official is available by appointment; bring the property’s records and proposed work into that discussion early.

Before the property decision
Check the records for an Alpine property
Check the bill for the particular estate
Alpine's Tax / Finance Department links an online service for viewing property-tax bills. The Borough distinguishes that informational lookup from a formal municipal tax search. Use the current bill in your ownership budget, and direct questions about the account to the Tax Office.
Trace the approvals behind the property
The Alpine Borough Clerk's page links the Borough's OPRA request form. Use that starting point to ask about existing construction and land-use records for the address under consideration. Describe the records sought so the discussion concerns the particular property and proposed work.

By the Borough’s code
What is the minimum lot size in Alpine, NJ?
It depends on the zoning district. Chapter 220 of the Borough Code, the Zoning Ordinance of the Borough of Alpine, sets a minimum lot area for each residential district: 87,120 square feet, two acres, with 250 feet of width in the R-A and R-R districts; 65,340 square feet, an acre and a half, in R-AA; 40,000 square feet in R-1; and between 20,000 and 7,500 square feet in the R-2, R-3 and R-4 districts. Its Schedule Limiting Height and Bulk of Buildings adds the setbacks: a 75-foot front yard, 100-foot rear yard and 50-foot side yards in the two-acre districts, and 35 feet and two and a half stories of height in every district but R-4. Building coverage is capped at 9 percent of the lot in the two largest-lot districts and R-1, and at 10 percent elsewhere; improved lot coverage at 25 and 20 percent. Which district a parcel sits in is a question for the Borough’s zoning map and zoning officer, and the lot-area figure is where any discussion of an addition, a pool or a rebuild begins.
| District | Minimum lot area | Minimum width | Front / rear / each side yard | Maximum building coverage | Maximum improved coverage | Height |
|---|---|---|---|---|---|---|
| R-A | 87,120 sq ft (2 acres) | 250 ft | 75 / 100 / 50 ft | 9% | 25% | 35 ft, 2½ stories |
| R-R | 87,120 sq ft (2 acres) | 250 ft | 75 / 100 / 50 ft | 9% | 25% | 35 ft, 2½ stories |

| R-2B | 10,000 sq ft | 75 ft | 20 / 15 / 15 ft | 10% | 20% | 35 ft, 2½ stories |
| R-4 | 10,000 sq ft | 70 ft | 60 / 30 / 10 ft | 10% | 20% | 35 ft, 2 stories |

No. 832), as published by General Code (eCode360), read October 25, 2026.

Alpine in the Division of Taxation’s tables.
What the State publishes about residential property tax in Alpine, taken from the New Jersey Division of Taxation’s own tables for tax year 2025 and its 2026 assessment list. Averages describe the municipality, not any one home; a given property’s bill is its own assessment times the rate.
| General tax rate, 2025 | 0.837 per $100 of assessed value |
|---|---|
| Effective tax rate, 2025 | 0.794 |
| Average residential assessment, 2025 | $2,782,718 |
| Average residential tax bill, 2025 | $23,291 |
| Residential sales tabulated, 2025 | 17 · average price $4,199,588 |
| Residential line items, 2025 | 666 |
| Average residential assessment, 2026 list | $2,834,789 |
Figures as published by the New Jersey Division of Taxation: 2025 General Tax Rates by County and Municipality, 2025 Average Residential Statistics and 2026 Average Residential Statistics, read 13 September 2026. For Alpine, the 2025 general tax rate is 0.837 per $100 of assessed value — the multiplier a bill is computed from — and the effective tax rate is 0.794, the Division’s statistical comparison of districts assessed at full value, which its own definitions say is not to be used to compute a bill. What the two rates mean, and how Alpine compares with the other towns on this site, is set out in the Bergen County property-tax guide. The 2026 figure is the assessment list against which the 2026 rate will be struck once the county certifies it. The same figures for all seventeen town pages are published as data at /data/town-tax.json.
