Multifamily takeoffs
Unit-by-unit quantities for downtown infill buildings, including typical floor repeats, balconies, and roof decks.
SF · EA · LFWe produce quantity takeoffs and CSI MasterFormat estimates for New Rochelle contractors, developers, and owners — from downtown multifamily towers to Sound Shore renovations — delivered in Excel and PDF with marked-up plan sets.
New Rochelle pricing is driven by Westchester County labor rates, deep rock and tidal soils near the Long Island Sound shoreline, tight downtown infill logistics, IBC high-rise and NFPA 13 sprinkler scopes on multifamily towers, and Con Edison service coordination for electric-heavy buildings.
New Rochelle sits in Westchester County, where construction costs run above national averages and labor is priced against the New York metro market. The city's recent permit volume is almost entirely multifamily infill — 126 of 140 new privately-owned residential units in 2025 were in multifamily buildings, with $47M in permitted value and an average of $339,100 per unit. That mix means your estimates lean on concrete, structural steel, MEP, and fire protection rather than single-family framing.
We build takeoffs from your plan set in Bluebeam Revu and PlanSwift using ZIP-code-adjusted RSMeans data, then organize the estimate by CSI MasterFormat division so your bid package lines up with how general contractors and owners review scopes. If you bid work across the region, our New York construction estimating page covers the state-level cost picture, and we also serve nearby Yonkers and Mount Vernon.
For bidders. You get a division-by-division takeoff with quantities, waste factors, and unit costs you can drop into your bid form. We flag scope gaps and alternates so your number holds up at buyout.
For builders. We price your own crews and subcontractor scopes against ZIP-adjusted labor and material rates, then mark up the plan set so your foreman can find every quantity on the sheet.
For owners. You get a budget estimate and a basis-of-estimate narrative for downtown infill and Sound Shore projects, with assumptions called out so you can compare bids apples to apples.

140 new housing units in 2025 (+2700% vs 2024).
14 single-family · 126 multifamily (90%).
New Rochelle issued permits for 140 new privately-owned residential units in 2025, up from 5 in 2024 — a 2,700% jump. Multifamily accounted for 126 units, or 90% of the total, and permitted value reached $47M. For bidders, that means most of the work in this city is mid- and high-rise residential: cast-in-place concrete or steel frame, podium construction, NFPA 13 sprinkler systems, and full MEP scopes. Single-family permits were only 14 units, so don't build your New Rochelle backlog around wood-frame residential takeoffs. Compare this to the steadier public and infrastructure work described on our New York construction estimating page, and note that nearby Yonkers and Mount Vernon show similar downtown multifamily patterns.
The $47M permitted value across 140 units works out to about $339,100 per unit — a figure that reflects Westchester County land, union labor, and the concrete-and-MEP-heavy nature of downtown infill. New Rochelle ranked 10th of 24 covered state cities by units and took 3.9% of the 3,635 covered state units. When you estimate here, don't apply national $/SF averages: build the number from quantity takeoffs by division, then apply ZIP-code-adjusted material and labor pricing. If you are bidding against contractors who work in Schenectady or Utica, their labor rates will not match New Rochelle's.
We take off and price the scopes that show up most in New Rochelle's multifamily, commercial, and shoreline work.

Westchester sites often hit glacial till, weathered rock, and high groundwater, so footing, dewatering, and backfill quantities swing bids. We take off formwork by contact area and rebar by bar list, not by rule of thumb.
You need a budget before design is complete. We issue a basis-of-estimate narrative with assumptions and alternates so your pro forma reflects what the drawings actually show, not a square-foot guess.
When three bids arrive with different scopes, a third-party takeoff by CSI division shows where the gaps are. We mark up the plan set so every quantity traces back to a sheet and detail.
Roof replacement, facade repairs, and MEP upgrades on older Sound Shore buildings need phased budgets. We price by building section so you can schedule work around tenants and funding cycles.
Labor rates, union agreements, and Westchester material pricing differ from most markets. ZIP-code-adjusted RSMeans data and local productivity assumptions keep your first New Rochelle number from being a costly lesson.
We estimate from plan sets for projects anywhere in the New Rochelle area and the surrounding Westchester and lower Hudson corridor. If your site is near a train station or on the Sound Shore, the logistics assumptions in the estimate change accordingly.
The city's 2025 permit mix was 126 multifamily units against 14 single-family units, so most of what we price here is attached housing, mixed-use, and the site and structural work that comes with it.
Five to eight stories over podium or garage, typically cast-in-place or precast concrete with masonry veneer. We take off concrete by cubic yard, formwork by contact area, and rebar by bar list, then price MEP by fixture and riser count.
Watch for: Podium transfer slabs, unit-mix changes, and NFPA 13 sprinkler zoning.
Ground-floor retail under residential floors brings separate structural systems, storefront glazing, and tenant MEP stub-outs. We split landlord versus tenant scope so your bid shows what the base building actually includes.
Watch for: Storefront systems, grease and vent risers, separate utility metering.
Tear-downs and narrow-lot builds on older platted streets. Framing, foundation, and utility connection quantities depend on how much of the existing structure stays, so we price both demolition and new work as separate line items.
Watch for: Demolition allowances, rock excavation, utility reconnection fees.
Projects built under local affordability requirements often carry prevailing wage or specific finish standards. We separate hard costs from soft cost allowances and flag items that change when funding sources change.
Watch for: Prevailing wage triggers, accessibility clearances, durable finish specs.
Older masonry and timber buildings downtown converted to residential or office. Existing conditions drive the estimate, so we price selective demolition, structural reinforcement, and new MEP distribution as measurable scopes.
Watch for: Unknown structural conditions, abatement, elevator and egress upgrades.
Schools, medical offices, and retail fit-outs in existing shells. Partition types, ceiling systems, and mechanical distribution drive cost more than floor area, so we take off by room and system rather than by square foot.
Watch for: After-hours work, infection control, sprinkler and alarm modifications.
Cost drivers here are a mix of dense-site logistics, older infrastructure, and Westchester labor pricing. The items below are the ones that most often move a New Rochelle number after the first pass.
New York State adopts the IBC and IRC with local amendments, and New Rochelle reviews projects through its own building department, planning board, and, for waterfront sites, environmental review. Review cycles and required submissions affect your carrying costs, not just your hard costs. Confirm the adopted code edition and any local amendments with the city building department before you lock a schedule or a general conditions number.
IBC · IRC · New Rochelle Building Department · Westchester CountyMuch of Westchester sits on glacial till, decomposed rock, and areas of high groundwater near the Sound. That means test pits and borings drive whether you price spread footings, caissons, or rock anchors, and whether dewatering and sheeting are separate line items. We carry excavation, backfill, and disposal by volume so a foundation bid does not absorb an unplanned soil condition.
Glacial till · High groundwater · Rock excavation · DewateringCoastal New Rochelle faces wind-driven rain, nor'easters, and flood-zone requirements near the shoreline. Roof assemblies, facade drainage planes, and below-grade waterproofing need to be priced as systems, not allowances. Wind uplift and flood elevation requirements can change structural and envelope quantities, so confirm the applicable flood zone and exposure category with the local building department.
Nor'easters · Flood zones · Wind uplift · WaterproofingNew Rochelle labor is priced against the New York metro market, where union trades and prevailing wage requirements on public or subsidized work raise hourly costs well above national averages. Productivity assumptions also change on occupied renovations and tight downtown sites. We use ZIP-code-adjusted labor rates and note where a project's funding source may trigger wage requirements.
New York metro labor · Union trades · Prevailing wage · ProductivityDowntown lots are narrow, often with no staging area, so crane picks, deliveries, and concrete pours need permits and traffic control. Stormwater management is reviewed under state and local requirements, and many sites need detention or infiltration systems. We price those as separate scopes so they do not get buried in sitework.
Stormwater management · Detention systems · Traffic control · SiteworkMost structural steel, precast, and mechanical equipment comes from outside Westchester, so freight, delivery windows, and laydown space affect material pricing. Sales tax treatment also varies by contract type and project use. We build material costs from ZIP-adjusted pricing and identify where tax or freight assumptions should be verified before the bid is submitted.
Structural steel · Precast · Freight · Sales taxThe city's 2025 permit mix — 140 new privately-owned residential units, 126 of them multifamily, per the U.S. Census Bureau Building Permits Survey — tells you which divisions carry the risk on a New Rochelle takeoff. Here is how we read each trade.
Downtown and waterfront parcels along the Long Island Sound shore sit on fill, glacial till, and in places exposed bedrock, so we separate unclassified excavation from rock removal and price them as different line items — 31 23 16 for trenching, 31 23 23 for structural fill, 31 11 00 for clearing. Dewatering is a real cost on sites near Echo Bay and the Huguenot Park area where the water table is shallow. We carry a line for sheeting and shoring when the excavation depth exceeds what open-cut allows. See our sitework estimating services for the full division 31 breakdown.
Mid-rise residential in New Rochelle is usually wood-frame over a podium or steel-and-metal-deck, so the takeoff splits at the transfer level. We count studs by length and spacing, deduct openings over 8 SF, and add 5–10% waste on dimension lumber, a typical allowance. Structural steel is taken off by piece mark from the shop drawings with a separate line for connection material and fireproofing. On wood-frame buildings we verify the sheathing and blocking quantities against the shear wall schedule. Framing estimating services covers the division 05 and 06 methods in detail.
High-rise residential drives MEP quantities off fixture counts, riser diagrams, and dwelling-unit schedules rather than floor area. We take off plumbing fixtures by unit type, sprinkler heads by hazard classification with a line for standpipes and the fire pump, and branch wiring by device count with homerun lengths. Panels, transformers, and switchgear are counted from the one-line diagram. Sprinkler and alarm scope often lands with a specialty sub, so we flag it as a separate bid package. MEP estimating services and multi-family estimating services show how we structure divisions 21 through 28.
Multifamily work here generally means cast-in-place footings and pile caps, slab-on-deck, and elevator pit walls. We take off 03 30 00 by pour sequence — footings, walls, columns, elevated slabs — and apply waste factors of roughly 5% on formed concrete and 7–10% on slab-on-grade, typical ranges you should verify against your own historical yield. Formwork is measured in contact area (SFCA), not cubic yards, which is where low bids usually leak. Rebar is taken off by bar size and lap-adjusted length. Our foundation estimating services and concrete estimating services pages show the deliverable format.
Sound-side buildings take wind-driven rain, so we take off roof systems by area with perimeter and penetration lengths broken out separately — 07 51 00 for modified bitumen, 07 54 00 for TPO, 07 21 00 for insulation. Flashing, edge metal, and counterflashing are lineal-foot items; they are the first thing cut from a competing bid. For multifamily buildings we also count balcony and terrace waterproofing by square foot, plus through-wall flashing at every shelf angle. Roofing estimating services lists the assemblies we price. Confirm the adopted energy code edition and required R-values with the New Rochelle building department before you lock the spec.
Quick check for a single element. For a full drawing set, send the plans and we measure everything, including the items calculators miss.
Typical waste: 3–5% for slabs, 5–10% for footings and walls. Truck count assumes 10 CY loads; confirm load size with your ready-mix supplier.

This example prices continuous strip footings for a four-story multifamily building on a level lot. All dimensions are illustrative — substitute your own plan dimensions before using any of these figures.
Start from the foundation plan. Assume a continuous footing 2'-0" wide by 1'-0" thick running 480 linear feet around the building perimeter, plus 120 linear feet of interior bearing wall footings at the same section.
| Step | Calculation | Result |
|---|---|---|
| Total footing length | 480 LF + 120 LF | 600 LF |
| Cross-section area | 2.00 ft × 1.00 ft | 2.00 SF |
| Net concrete volume | 600 LF × 2.00 SF ÷ 27 CF/CY | 44.4 CY |
| Waste allowance (5%, typical) | 44.4 CY × 1.05 | 46.6 CY |
| Order quantity (½ CY round-up) | 46.6 → 47.0 | 47.0 CY |
Now attach labor and material. Concrete is priced per cubic yard delivered, adjusted for the New Rochelle ZIP code, with a separate line for the pump or chute because access at the site perimeter drives that choice. Formwork is measured separately in square feet of contact area: for this footing, two sides at 1'-0" high over 600 LF gives 1,200 SF, and the footing ends add a small amount. Rebar is taken off from the footing schedule by bar size, with lap lengths added — a typical 5% to 7% allowance over net calculated weight.
The failure mode to watch: bidding the footing as a single cubic-yard number that quietly includes formwork and rebar. When the competing bid shows only 44 CY with no separate form or steel lines, the difference is not efficiency, it is missing scope. We deliver footing takeoffs with concrete, formwork, reinforcing, and vapor barrier as separate CSI line items, marked up on the plan set, in Excel and PDF within 24–48 hours for most projects. Send the foundation and structural sheets through our get an estimate page and we will return the quantities by division.
The figures come from the U.S. Census Bureau Building Permits Survey for 2025. They count new privately-owned residential units permitted by the city itself — 140 total, of which 126 were multifamily and 14 single family, with a permitted value of $47M. The survey does not include commercial, institutional, or renovation permits, and it does not include units permitted by other jurisdictions. Use the numbers as a demand signal, not as a complete picture of construction activity in New Rochelle.
With 126 of 140 permitted units in multifamily buildings — about 90% — the takeoff shifts toward repeated dwelling-unit assemblies: unit-by-unit fixture counts, stacked plumbing risers, corridor and shaft-wall details, and podium-level structure. Repetition helps, but it also means a single error in a typical unit multiplies across the building. We build a typical unit once, verify it against two or three unit types, then extend by count and confirm the total against the floor plans.
We price with ZIP-code-adjusted material and labor rates, so Westchester County costs are reflected rather than a national average. That matters most on labor-heavy divisions — formwork, drywall, and finish trades — where the local wage and productivity assumptions move the number more than material pricing does. If you have recent subcontractor quotes from a New Rochelle or Westchester job, send them and we will benchmark our rates against them before finalizing the estimate.
It is common enough that we never bury it in a lump sum. We take off unclassified excavation separately from rock removal and carry a unit price per cubic yard for rock so the owner can see the exposure. Unsuitable material is priced as removal plus disposal plus replacement fill, with the haul-off counted by truckload. If a geotechnical report is available, we read the boring logs and adjust depths and quantities accordingly. Without one, we note the assumption on the takeoff so nobody mistakes it for a surveyed quantity.
Yes. We cover New Rochelle and the surrounding Westchester and upstate markets, including Yonkers, Mount Vernon, Syracuse, Albany, Schenectady, and Utica. Rates and code editions differ by jurisdiction, so we price each project to its own ZIP code and note which code cycle applies. If you are bidding the same building type in two cities, we can issue parallel takeoffs so you can compare labor and material side by side before you set your markup.
Architectural, structural, and MEP drawings in PDF, plus any specifications, schedules, and addenda. A geotechnical report helps on foundation work, and a survey or civil set helps on sitework. If the drawings are at 50% or 90% design, say so — we will note which quantities are provisional. Marked-up plan sets come back with the takeoff so your estimator can trace every line item to the sheet it came from. Most projects turn around in 24–48 hours, with rush available.
Prevailing wage and union agreements change the labor rate, not the quantity, so we take off the same quantities and apply the wage basis you specify. Tell us at the start whether the project is public, private, or a mix, and whether a project labor agreement applies. We then price labor hours against that basis and keep the rate assumption visible on the summary sheet, so a reviewer can see exactly where the labor cost came from.
Yes, and we recommend it. Roof area is straightforward, but the cost sits in perimeter and penetration detail — edge metal, counterflashing, curb flashing, and roof drains — all measured in lineal feet. On Sound-side buildings, wind uplift requirements can push the fastener pattern and membrane thickness up, so we price the specified assembly rather than a default. If you are a roofing subcontractor bidding to a general contractor, we can format the takeoff to match the bid form you were given.
Excel and PDF, organized by CSI MasterFormat division, with the marked-up plan set included. The Excel file carries quantities, units, and unit costs on separate columns so you can adjust rates or apply your own markup without rebuilding the sheet. We work in Bluebeam Revu and PlanSwift, with RSMeans data as a pricing reference. If you need the estimate mapped to a specific bid form or a subcontractor's schedule of values, send the form and we will match it.
Quantities are traceable — every line item ties to a sheet, a detail, or a schedule, and the marked-up set shows where. Where the drawings are ambiguous, we list the assumption rather than guess silently, so you can confirm it with the design team before the bid goes in. We do not publish an accuracy percentage, because accuracy depends on drawing completeness and how the scope is defined. What we can commit to is a documented takeoff you can audit line by line.
Upload your drawings and we will return a division-by-division takeoff in Excel and PDF, with marked-up plans, in 24–48 hours.
