What makes construction estimating in Centennial, CO different?

Centennial's 2025 permit mix is 100% single-family — 194 units, zero multifamily — so estimates skew toward custom and semi-custom homes. Key cost drivers include expansive clay soils along the Front Range, wind and hail exposure driving roofing and exterior specs, Denver-metro labor rates, and Arapahoe County permitting and inspection sequencing.

  • Centennial permitted 194 new housing units in 2025, #16 among the Colorado cities we cover.
  • About 0% were in multifamily buildings; 100% were single-family.
  • Permit volume was up 646% compared with 2024.

Centennial sits in Arapahoe County, south of Denver and north of the Castle Rock corridor, where most of the 2025 residential work was single-family infill and small subdivision platting rather than large multifamily pods. That matters at bid time: with no multifamily units permitted by the city in 2025, your competition is other single-family builders, and the estimate has to hold up house by house instead of averaging over a 200-unit podium. We build takeoffs at that granularity — each plan, each elevation, each option.

We price with ZIP-code-adjusted material and labor data and deliver Excel and PDF files organized by CSI MasterFormat division, with marked-up plan sets you can hand to a superintendent. Most projects turn in 24–48 hours, with rush available. If you are bidding Front Range work outside Centennial, our Colorado construction estimating team covers the whole corridor, including Arvada and Westminster.

For bidders. You need a number you can defend line by line. We return division-coded quantities with waste factors stated, so you can adjust framing, concrete and roofing assumptions before the bid date instead of after.

02

For builders. Production builders in Arapahoe County run the same plan across multiple lots. We take off the base plan plus options, so your purchase orders and change orders start from a consistent quantity baseline.

03

For owners. If you are building one custom home in Centennial, you still want a check against the contractor's bid. We provide an independent takeoff you can compare scope against, item by item, before you sign.

Centennial

194 new housing units in 2025 (+646.2% vs 2024).

194 single-family · 0 multifamily (0%).

194 single-family permits, zero multifamily

The city issued 194 new privately-owned residential units in 2025, up from 26 in 2024 — a 646% increase — and every one was single-family. Permitted value was $54M, averaging $275,900 per unit. For bidders, that means the pipeline is detached homes, not apartment pods, so your estimate needs full exterior envelopes, individual utility services and per-house sitework rather than shared systems. Centennial ranked 16th of 21 covered Colorado cities by units and accounted for 1.1% of the 16,921 units permitted statewide. If you also bid north-metro work, our Boulder and Longmont pages follow the same format.

Where the money goes on a Centennial house

At roughly $275,900 average permitted value per unit, the cost is concentrated in the structure and envelope, not in shared infrastructure. Expect excavation and foundation to carry real weight because Front Range soils include expansive clay that often drives over-excavation, moisture conditioning or pier systems; confirm geotechnical recommendations before you price. Roofing and exterior finishes are bid against hail and wind exposure, which pushes toward Class 4 impact-rated shingles and heavier underlayment. MEP is per-house — individual taps, meters and panels. See our foundation and roofing takeoff pages for how we structure those divisions.

Who we provide estimates for

Who we prepare Centennial estimates for

Production home builders

Centennial permitted 194 single-family units in 2025 and no multifamily, so builders here run the same plan across multiple lots. We take off base plans plus options for consistent purchase orders.

Custom home builders

Infill lots in Arapahoe County often mean one-off plans with walkout basements and varied elevations. We build each takeoff from that specific plan, not a template.

General contractors

You are bidding against other Front Range builders on house-by-house scopes. We return division-coded quantities with stated waste factors so you can adjust before bid day.

Subcontractors

Concrete, framing and roofing crews working Centennial subdivisions need quantities tied to each lot. We mark up the plan set so your foreman can verify before you mobilize.

Developers

Small subdivision platting south of Denver requires per-lot sitework and utility quantities. We estimate those scopes so your lot budgets hold before you sell.

Owners and architects

If you are building one custom home in Centennial, an independent takeoff lets you compare a contractor's bid scope line by line before you sign.

Property types

Types of Centennial properties we estimate

Centennial's 2025 permit mix was entirely single-family, 194 units with zero multifamily, so our work here leans toward detached homes, infill lots and the small commercial and institutional buildings that serve those neighborhoods.

Single-family detached

The core of Centennial permitting. We take off framing, concrete flatwork, roofing and finishes per plan and elevation, with option packages priced separately so your base bid stays clean.

Watch for: Elevation changes, optional basements, garage extensions

Custom infill homes

Tear-down and infill lots in established Centennial neighborhoods often carry walkout basements, retaining walls and tighter staging. We estimate the sitework and foundation scope that production templates miss.

Watch for: Retaining walls, walkout excavation, utility relocations

Townhome and duplex

Small attached projects appear on infill parcels even when the city's multifamily permit count is zero. We separate party-wall, fire-rated assembly and shared utility quantities from the unit takeoff.

Watch for: Party walls, fire separation, shared utility trenches

Retail and office fit-out

Centennial's commercial corridors along Arapahoe Road and near the tech center support tenant improvements. We estimate demising walls, storefront, MEP rough-in and ceiling scope by division.

Watch for: Demising walls, storefront, above-ceiling MEP coordination

Light industrial and warehouse

Service and flex buildings in the south metro need slab, tilt or masonry wall, and racking-ready electrical quantities. We take those off separately from office build-out areas.

Watch for: Slab flatness, dock equipment, panel capacity

Schools and civic buildings

Institutional work in the Cherry Creek and Littleton school corridors follows public bid forms. We organize quantities by CSI division so your bid form lines map directly to our takeoff.

Watch for: Prevailing wage, bid alternates, phasing around school calendar

Local factors

What changes a construction estimate in Centennial

Centennial sits at the south end of the Denver metro, where soil, climate and permitting each move the number. These are the six factors we check on every takeoff here.

Permitting and code cycle

Centennial issues its own residential permits, and Arapahoe County handles some unincorporated parcels nearby. Plan review comments on energy code and structural sheets can add a revision cycle before you break ground, so carry a allowance for resubmittal time in your schedule. Confirm the adopted IBC, IRC and IECC editions with the city building department before you finalize specs.

City of Centennial Building Division · Arapahoe County · IECC · IRC

Soils and foundations

Front Range soils along the south metro include expansive clay and bentonite pockets, and some lots carry undocumented fill from earlier grading. Geotechnical reports often call for over-excavation, moisture conditioning or drilled piers instead of standard spread footings. Those decisions change concrete volume, rebar and backfill quantities, so we price the foundation from the soils report rather than a default detail.

Expansive clay · Drilled piers · Over-excavation · Geotechnical report

Climate and hail

Hail is the dominant roofing risk on the Colorado Front Range, and it drives shingle class, underlayment and sometimes impact-rated windows. Snow load and freeze-thaw cycles affect roof framing, exterior concrete and drainage details. We state the roofing system assumed in the takeoff so you can compare bids on the same assembly instead of guessing.

Class 4 shingles · Snow load · Freeze-thaw · Ice and water shield

Labor market

The Denver to Colorado Springs corridor keeps framing, concrete and MEP crews busy, and labor rates in Centennial track the metro rather than rural Colorado. Bid days that land in a busy season can come back higher than the same scope in winter. We price with ZIP-code-adjusted labor so your number reflects the local market, not a state average.

Front Range labor · ZIP-adjusted rates · Framing crews · MEP trades

Sitework and drainage

Centennial lots range from flat prairie to sloped parcels backing to open space, and drainage requirements change the earthwork quantity fast. Grading, swales, retaining walls and utility trenching are often the largest swing item between two similar houses. We take off sitework separately so you can see what the lot, not the plan, is costing you.

Grading · Swales · Retaining walls · Utility trenching

Materials and logistics

Most Centennial material comes through Denver metro suppliers, so delivery is short but yard space on infill lots is tight. Truss lead times, concrete scheduling and staging constraints can add handling cost that a plan-only takeoff misses. Colorado has no statewide sales tax, and local taxes vary by jurisdiction, so confirm the applicable rate with your supplier or the city finance office.

How Centennial conditions show up in a takeoff, trade by trade

Centennial sits in Arapahoe County on the Front Range, where expansive clay soils, a short but intense construction season, and hail exposure shape what you actually quantify. Each trade below carries line items that a generic national takeoff will miss.

Sitework and utilities

Centennial's rolling terrain and clay subgrade mean you cannot price a simple cut-and-fill from a site plan alone. A real takeoff measures stripping depth, topsoil stockpile volume, and over-excavation below footings in cubic yards, then adds import or export by truckload. Storm drainage runs to curb inlets and detention, so you quantify trench length, bedding stone by ton, and PVC or RCP pipe by linear foot with fittings. If the civil drawings show a sanitary tap to a district main, count the tap, the wy e, and the manhole separately. For a complete site package, see our sitework estimating services.

Framing and shell

Centennial's single-family work is largely wood frame over a basement or crawl space. A framing takeoff counts plates, studs, headers, and joists by piece, then converts to board feet for lumber pricing; sheathing is by sheet with a typical 5–10% cut waste. Roof framing must account for the wind and snow loads in the adopted code, which can drive closer rafter spacing or heavier trusses than a national template assumes. Wall and roof sheathing, housewrap, and flashing are separate line items. Our framing estimating services cover the full shell, and roofing estimating services handle the steep-slope and low-slope assemblies.

MEP and interior finishes

Mechanical, electrical, and plumbing takeoffs in Centennial homes are driven by fixture and outlet counts, not by square foot. Count lavatories, water closets, hose bibs, and floor drains; count panel, branch circuits, receptacles, switches, and light fixtures by type. HVAC is by ton of cooling and by linear foot of duct, with registers and thermostats as each. Insulation goes in by square foot of wall, ceiling, and rim area with the R-value the energy code requires. Drywall is by sheet with a typical 10–15% waste. Our MEP estimating services and residential estimating services cover these divisions.

Concrete and foundations

Arapahoe County's expansive soils drive the foundation scope more than the building size does. You quantify continuous footings and stem walls by linear foot, slab-on-grade by square foot with a typical 5–10% waste, and pier or caisson counts where a geotechnical report calls for drilled elements. Rebar is priced by pound or by bar length with lap and dowel waste; vapor barrier and rigid insulation go in by square foot with overlap. Flatwork is separate: driveways, walks, and patios in square feet with control joints by linear foot. Our concrete estimating services and foundation estimating services break these out by division.

Roofing and exterior envelope

Hail is the defining exterior cost in Centennial. You quantify roof area in squares (100 square feet) from the plan dimensions plus overhangs and pitch factor, then add ridge, hip, valley, and starter by linear foot. Underlayment, ice-and-water at valleys and eaves, and class 4 impact-rated shingles are separate lines because the insurance and resale math depends on them. Wall cladding, WRB, and flashing are measured by square foot of wall area, not floor area. Gutters and downspouts are by linear foot. Confirm the adopted code edition and any local amendment with the building department before you lock the assembly.

Scope gaps we see on Centennial bids

  • Over-excavation and structural fill below footings omitted because the geotechnical report was not read before pricing.
  • Rock excavation left as a unit-price allowance with no defined quantity or measurement method.
  • Roof pitch factor and overhang area excluded, so shingle squares come in low by 10–20%.
  • Ice-and-water membrane and class 4 impact shingles not separated from base underlayment.
  • Temporary power, jobsite fencing, and final grade not assigned to any trade in the bid form.
  • Permit fees, plan review, and utility connection charges carried as a lump sum with no backup.

Worked example: slab-on-grade concrete for a Centennial single-family home

This example prices a slab-on-grade for a 2,400 square foot single-family home in Centennial. The dimensions are illustrative and do not represent a specific address. We assume a 4-inch slab with a 12-inch thickened edge, 6x6-W1.4xW1.4 welded wire mesh, and a 10-mil vapor barrier. Waste factors are typical for residential flatwork.

StepCalculationQuantityUnit
Slab area40 ft x 60 ft2,400SF
Slab volume2,400 SF x (4 in / 12)800CF
Edge volume160 LF x (12 in / 12) x (12 in / 12)160CF
Total volume800 + 160960CF
Convert to CY960 / 2735.6CY
Waste at 7%35.6 x 1.0738.1CY
Vapor barrier2,400 x 1.102,640SF
Mesh2,400 / 100 x 1.1026.4rolls

Concrete is ordered by the cubic yard, so the 38.1 CY figure is what goes on the purchase order. The 7% waste covers spillage, uneven subgrade, and the thickened edge not being perfectly uniform. Vapor barrier carries 10% for laps and cuts. Mesh is priced by roll covering 100 SF, with 10% for side and end laps.

Two Centennial-specific adjustments matter here. First, expansive clay subgrade often requires over-excavation and structural fill below the slab; that is a separate line item measured in cubic yards of import and is not included in the 38.1 CY above. Second, the slab must be isolated from the foundation stem wall where the soils report calls for it, which adds isolation joint material by linear foot. Confirm the geotechnical recommendations and the adopted code edition with the local building department before you finalize quantities. For a full flatwork package, our concrete estimating services cover slab, footing, and flatwork divisions together.

FAQ

Centennial construction estimating questions

How long does a Centennial takeoff take?

Most residential and light commercial takeoffs are returned in 24–48 hours from the time we receive a complete plan set. Larger or multi-building projects may take longer, and we will tell you the schedule before we start. Rush turnaround is available when you have a bid date inside that window. Send the architectural, structural, civil, and MEP drawings together so we can price the full scope instead of issuing a partial takeoff.

What formats do you deliver?

We deliver Excel workbooks and PDF reports organized by CSI MasterFormat division, with marked-up plan sets showing what was measured. The Excel file lets you adjust quantities, add your own pricing, and roll up to a bid form. The PDF is useful for review and for attaching to a proposal. If your estimating team uses a specific template, tell us at kickoff and we will match the column structure.

Do you price Centennial work with local labor and material rates?

Yes. We use ZIP-code-adjusted material and labor pricing, so the rates reflect the Denver metro market rather than a national average. That matters for concrete, framing labor, and roofing, where the local market moves independently of the national index. We also use RSMeans data as a baseline and adjust for the specific scope, access, and site conditions shown on your drawings.

What software do you use?

We work in Bluebeam Revu for plan review and markup, PlanSwift for quantity takeoff, and RSMeans data for pricing. That combination lets us measure directly from the PDF, tag each line item to a drawing location, and produce a priced estimate without re-keying quantities. You receive the marked-up set so you can see exactly where each number came from.

Where does the Centennial permit data on this page come from?

The permit figures come from the U.S. Census Bureau Building Permits Survey for 2025, counting permits issued by the city itself for new privately-owned residential units only. That means the 194 units and $54M permitted value cover single-family and multifamily housing starts, not commercial or industrial permits. The survey is a useful demand indicator, but it is not a complete measure of construction activity in Centennial.

What does the 2025 permit data say about Centennial?

The city issued 194 new privately-owned residential units in 2025, up from 26 in 2024, a 646% increase. All 194 units were single-family; multifamily was zero. The permitted value was $54M, or about $275,900 per unit. Among the covered Colorado cities, Centennial ranked 16 of 21 by units and accounted for 1.1% of the state total of 16,921 units. The jump reflects a small base in 2024 more than a sustained trend, so treat one year as a signal, not a forecast.

Do you cover projects outside Centennial?

Yes. We cover the Front Range and the rest of Colorado, including Arvada, Westminster, Pueblo, Boulder, Greeley, and Longmont. If your project is in one of those cities, the takeoff still uses ZIP-code-adjusted pricing for that location. You can start from our Colorado construction estimating page or send plans directly through the estimate request form.

What do you need to start a takeoff?

Send the complete plan set: architectural, structural, civil, and MEP drawings, plus the geotechnical report if one exists and any specifications or addenda. If the drawings are issued for bid, include the bid form and the date. If something is missing, we will tell you what we can price and what we will carry as an allowance so the gaps are visible rather than buried.

How do you handle Colorado's expansive soils in a takeoff?

Expansive clay is common along the Front Range, so we read the geotechnical report before pricing foundations. If the report calls for over-excavation, structural fill, or a specific pier depth, those become separate line items measured in cubic yards or by count. If no report is provided, we note the assumption and recommend you confirm the foundation design with a local geotechnical engineer. The adopted code edition and any local amendment should be confirmed with the building department.

Can you estimate both residential and commercial work in Centennial?

Yes. Centennial's recent permit activity is almost entirely single-family, but the city also has commercial and light industrial work along the corridors. We estimate both, using the same division-by-division approach. Residential takeoffs emphasize framing, flatwork, and finishes; commercial takeoffs add structural steel, storefront, and larger MEP systems. Tell us the project type at kickoff so we apply the right waste factors and labor assumptions.
