What makes construction estimating in Fontana, CA different?
Fontana pricing turns on San Bernardino County soil and grading, hot inland summer heat that drives roofing and HVAC sizing, warehouse and logistics tilt-up work, and ZIP-code-adjusted material and labor rates. Residential permits fell 32% year over year, so bidders face tighter competition on fewer starts.
- Fontana permitted 930 new housing units in 2025, #9 among the California cities we cover.
- About 38% were in multifamily buildings; 62% were single-family.
- Permit volume was down 32% compared with 2024.
Fontana sits in San Bernardino County at the base of the Cajon Pass, where the Santa Ana winds, expansive soils and hot inland summers shape what you build and how you price it. The city's 2025 residential permit count was 930 units, down 32% from 1,358 in 2024, with 38% of those units multifamily and an average permitted value of $206,900 per unit. That mix pulls estimating work in two directions at once: production single-family plans and mid-rise apartment shells.

Residential permits fell 32% — what that means for your bid
Fontana permitted 930 new privately-owned residential units in 2025 against 1,358 in 2024, a 32% drop, per the U.S. Census Bureau Building Permits Survey. Of the 2025 total, 575 were single-family and 355 were multifamily, so multifamily carried 38% of the volume. Permitted value was $192M, or $206,900 per unit. For bidders, fewer starts means more contractors chasing each job, and unit values that high leave little room for an unqualified number. When you price a Fontana tract or apartment building, separate the vertical cost from the sitework and utility trenching, because grading and offsite improvements are where bids get lost. Our residential estimating services and multi-family estimating services cover both sides of that split. Fontana ranked 9th of 25 covered California cities by units and took 2.5% of the 36,591 units permitted across those cities, so the local market is steady but not the state's largest.
Inland Empire industrial and commercial work
Fontana's logistics corridor along I-10 and I-15 keeps tilt-up warehouse, truck court and tenant improvement work in the pipeline even when housing cools. Those projects price differently from residential: concrete slab thickness and joint spacing, fire protection under NFPA 13, and electrical service sizing for refrigeration or charging equipment drive the number. California's high permitting costs and housing shortage keep per-project costs elevated statewide, which is why a Fontana bid cannot be priced off a generic national database. If you work across the county line, our San Bernardino construction estimating page covers the adjacent market, and commercial estimating services handles the shell and core scope. Confirm the adopted code edition with the City of Fontana building department before you finalize any code-driven line item.

Who we prepare Fontana estimates for
General contractors bidding public work
Fontana and San Bernardino County bid openings reward a clean, defensible number. We break out prevailing-wage labor, quantities by division, and unit prices so you can adjust your bid without rebuilding the takeoff.
Production homebuilders
Tract plans in the Etiwanda and Sierra Lakes areas repeat, so per-plan accuracy compounds across dozens of lots. We take off one plan, apply lot-specific sitework and concrete quantities, and price the model run.
Multifamily and apartment developers
With 38% of 2025 permitted units multifamily, mid-rise shells and podium decks drive the budget. We price structural concrete, framing, MEP rough-in and common-area finishes by building type.
Industrial and warehouse builders
The I-10 and I-210 corridors keep demand for tilt-up shells, slab-on-grade and racking-ready interiors. We take off slab thickness, panel geometry and site concrete so your shell bid holds.
Subcontractors pricing their scope
You need quantities you can install from, not a lump sum. We return marked-up plans with counts, lengths and waste factors for concrete, framing, roofing and MEP scopes.
Owners and developers budgeting
Before you commit to a pro forma, you need a control budget that separates shell, core, sitework and soft costs. We price alternates and phasing so you can see what drives cost.

Property types
Types of Fontana properties we estimate
Fontana's 2025 permit mix was 575 single-family and 355 multifamily units, so estimating here means pricing both production houses and attached apartment buildings.
Single-family tract homes
We take off one plan and apply it across the lot run, then add lot-specific sitework, concrete flatwork and utility trenching. Quantities are organized by CSI division so your trade partners can price directly.
Watch for: Lot grading, retaining walls, and utility trench lengths vary by pad elevation.
Multifamily apartments
Mid-rise and garden-style buildings need separate takeoffs for the podium, structural frame, exterior skin and common areas. We price unit mixes and amenity spaces so your per-unit cost is clear.
Watch for: Podium waterproofing, fire-rated assemblies, and elevator counts drive cost.
Industrial warehouse shells
Tilt-up and concrete tilt panels along the I-10 corridor require slab, panel and site concrete quantities. We break out dock equipment, racking-ready slabs and office build-out separately.
Watch for: Slab flatness, panel thickness, and dock apron concrete quantities.
Retail and commercial buildings
Strip centers, restaurants and service buildings need MEP, storefront and site work priced by division. We separate landlord shell from tenant improvements so you can bid either scope.
Watch for: Grease interceptors, hood systems, and utility capacity for restaurant shells.
Additions and ADUs
Homeowners and small builders adding square footage need quantities for framing, roofing, MEP extensions and finishes. We price from the existing plan and flag where existing systems may need upgrades.
Watch for: Roof tie-in, panel capacity, and foundation connection details.
Sitework and infrastructure
Grading, drainage, sewer, water and street improvements are often the largest cost on a Fontana lot. We take off cut and fill, pipe runs, structures and paving by station or area.
Watch for: Import/export balance, rock excavation, and storm drain sizing.
Local factors
What changes a construction estimate in Fontana
Estimating in Fontana means pricing for the Cajon Pass wind, expansive soils and a permitting process that varies by project type.
Permitting and code editions
Fontana enforces the California Building Standards Code, including CBC, CRC, CEC and CALGreen, but the adopted edition and local amendments change on a three-year cycle. Plan check comments on energy compliance, fire access and storm water can add review time and redesign cost. Confirm the current adopted edition and any city-specific amendments with the Fontana building department before you lock your estimate.
California Building Standards Code · CALGreen · Fontana Building and Safety DivisionExpansive soils and foundations
Much of Fontana sits on alluvial soils with clay content that swells when wet and shrinks when dry. Geotechnical reports typically call for deeper footings, post-tensioned slabs or over-excavation and recompaction. Those recommendations change concrete volume, rebar and formwork quantities, so we price from the soils report, not a generic foundation detail.
Geotechnical report · Post-tensioned slab · Over-excavationWind, heat and fire exposure
Santa Ana winds through the Cajon Pass drive roof uplift pressures and require specific nailing, strapping and roof covering attachments. Summer heat affects concrete curing, roofing adhesives and worker productivity. If your site is near the wildland-urban interface, ignition-resistant detailing and ember-resistant vents add scope that must be priced separately.
Cajon Pass wind · Roof uplift · Wildland-urban interfaceLabor market and trade availability
Inland Empire labor rates run below coastal Los Angeles but crews are shared across San Bernardino and Riverside County projects. Concrete, framing and MEP trades can be stretched when several large tracts or warehouse shells start at once. We price labor from current ZIP-code-adjusted RSMeans data and note where crew availability may affect your schedule.
Inland Empire labor · RSMeans data · Trade crew availabilityDrainage, grading and land use
Fontana's flat to gently sloping lots still need drainage plans for storm water, and the city requires compliance with its municipal storm water permit. Cut and fill balance, retaining walls and sewer lateral depths change sitework quantities significantly. We take off grading by area and pipe runs by station so you can see the dirt balance before you bid.
Municipal storm water permit · Cut and fill balance · Sewer lateralMaterials, logistics and taxes
Fontana's location on I-10 gives good access to concrete plants, lumber yards and steel suppliers, but haul distances to some sites and delivery windows still affect cost. California sales tax applies to materials, and fuel and trucking surcharges move with diesel prices. We price materials from current supplier quotes and ZIP-code-adjusted data, and flag where logistics add cost.

How Fontana conditions show up in a takeoff, trade by trade
Fontana sits in San Bernardino County, where expansive soils, high summer heat, and Santa Ana wind exposure change the quantities you carry in almost every division. These are the trades where local conditions move the numbers most.
Earthwork and sitework
Mass grading on Fontana pads usually runs to deeper cut than the finished pad elevation suggests, because the upper soils in the area are expansive and often need over-excavation and recompaction before footings go in. A takeoff should carry separate lines for stripping, on-site cut and fill balance, export or import of unsuitable material, and compaction testing by the geotechnical engineer. If the soils report calls for lime or cement treatment, that is a separate measured item, not an allowance buried in grading. Dust control and watering are real line items in Fontana's summer heat. For a full breakdown of these items, see our sitework estimating services.
Framing and structural steel
Wood framing dominates Fontana's single-family production, and the takeoff has to account for engineered lumber, roof sheathing with panel clips, and hold-down hardware specified for the local wind exposure. On the industrial side, pre-engineered metal buildings and tilt-up panels replace stick framing, and the steel takeoff should be by piece mark with connection hardware listed separately. Waste on framing lumber typically runs 5 to 8 percent, but panel layout drives the real number. Sheathing and drywall quantities should be netted against openings, not grossed. See our framing estimating services for the full assembly breakdown.
Mechanical, electrical and plumbing
Fontana's cooling load drives larger tonnage than coastal California markets, and duct runs in attic spaces need insulation values that meet the adopted energy code. On the electrical side, service size and panel schedules should be taken off fixture by fixture, not by square foot, because production plans vary widely. Plumbing takeoffs need to separate rough-in from fixtures and account for the sewer and water connection fees charged by the local agency. Confirm the adopted code edition and any local amendments with the Fontana building department before you finalize quantities. Our MEP estimating services cover all three trades.
Concrete and foundations
Post-tensioned slabs and thickened-edge footings are common on Fontana residential tracts, and the takeoff has to separate concrete, post-tension strand and anchorage, vapor barrier, and reinforcing steel, each with its own waste factor. Typical waste runs 5 to 10 percent on formed concrete and 3 to 5 percent on rebar, but the actual number depends on forming reuse and pour sequence. On commercial pads, watch for slab thickness transitions between warehouse floor and office build-out, which are easy to miss on a single-sheet plan. Our concrete estimating services cover both residential and tilt-up scopes.
Roofing
Roof coverings in Fontana have to handle intense UV and summer surface temperatures that shorten the life of lower-grade materials. Tile and standing-seam metal are common on residential, while industrial roofs usually specify a single-ply membrane over insulation. The takeoff needs separate lines for underlayment, battens or clips, flashing, and penetration boots, because those items are frequently left to the roofer's allowance and then disputed. Waste on tile runs higher than on shingles because of breakage. Our roofing estimating services break the assembly into measurable layers.
Scope gaps we see on Fontana bids
- Over-excavation and recompaction required by the geotechnical report, left out of the grading bid and picked up later as a change order.
- Post-tension strand, anchorage and stressing, listed as an allowance instead of a measured quantity by tendon length.
- Dust control, watering and street sweeping during grading, which are separate line items in San Bernardino County.
- Roof underlayment, battens and penetration flashing, left to the roofer's allowance and disputed after award.
- Utility connection fees and off-site improvements, which are often paid by the owner but still need to be shown on the bid form.
- Temporary power, fencing and final cleaning, which disappear from the bid when the schedule is compressed.

Worked example: post-tension slab for a Fontana single-family house
This example uses illustrative dimensions for a typical Fontana production house: a 40 ft by 55 ft rectangular footprint with a 2 ft by 6 ft porch extension. The slab is 5 in. thick with a thickened edge 12 in. wide by 24 in. deep. Waste on concrete is taken at 7 percent, typical for formed flatwork.
| Step | Calculation | Result |
|---|---|---|
| Main slab area | 40 ft x 55 ft | 2,200 SF |
| Porch area | 2 ft x 6 ft | 12 SF |
| Total slab area | 2,200 + 12 | 2,212 SF |
| Slab volume at 5 in. | 2,212 x (5/12) | 921.7 CF |
| Slab volume in CY | 921.7 / 27 | 34.1 CY |
| Thickened edge volume | (185 LF x (12/12) x (24/12)) / 27 | 13.7 CY |
| Total concrete | 34.1 + 13.7 | 47.8 CY |
| With 7% waste | 47.8 x 1.07 | 51.1 CY |
Rebar for the slab is taken off by bar length: #4 at 18 in. on center each way over 2,212 SF gives roughly 3,850 LF including laps and chairs, which converts to about 2.6 tons at 0.668 lb per LF. Post-tension strand is measured by tendon length from the placement drawings, not by area, and anchorage counts come off the same sheets.
The point of separating these lines is that each one carries a different waste factor and a different unit price. If you lump the thickened edge into the slab volume, you lose the forming and labor difference between a flat slab and an edge form. If you take rebar by area alone, you miss the lap and chair allowance. Confirm the slab thickness and tendon layout against the structural sheets before you price, because production plans in Fontana often revise between plan sets.
FAQ
Fontana construction estimating questions
Where does the permit data in this guide come from?
The permit counts come from the U.S. Census Bureau Building Permits Survey, which reports permits issued by the city itself for new privately-owned residential units only. For 2025, Fontana issued 930 units, down 32 percent from 1,358 in 2024. That covers single-family and multifamily residential, not commercial or industrial permits, so it is a measure of residential activity rather than total construction volume in the city.
What is the typical split between single-family and multifamily in Fontana?
Of the 930 residential units permitted in 2025, 575 were single-family and 355 were multifamily, so multifamily made up 38 percent of the total. That mix matters for estimating because multifamily work carries different unit costs for MEP rough-in, fire-rated assemblies, and common-area finishes. Our multi-family estimating services handle that scope separately from single-family production.
How does Fontana's soil affect foundation takeoffs?
Expansive soils are common in the Fontana area, so geotechnical reports often require over-excavation, recompaction, and sometimes chemical treatment before footings are placed. Those items belong in the earthwork and foundation divisions as measured quantities, not allowances. If the report calls for a post-tensioned slab, the strand and anchorage are separate line items from the concrete. Always price from the soils report and the structural sheets together, because one without the other will understate the scope.
Do you price Fontana projects with ZIP-code-adjusted labor and material rates?
Yes. We use ZIP-code-adjusted material and labor pricing, drawing on RSMeans data, so the rates reflect the Fontana market rather than a national average. That matters for trades where local labor availability moves the number, including concrete finishing, framing, and MEP rough-in. We deliver in Excel and PDF, organized by CSI MasterFormat division, with marked-up plan sets so you can see where each quantity came from.
What turnaround can I expect on a Fontana estimate?
Most projects turn around in 24 to 48 hours, and rush service is available if your bid date is close. Turnaround depends on the completeness of the plan set and whether the scope is clear. If structural, architectural, and MEP sheets are all present, we can usually finish inside that window. If sheets are missing, we will tell you what we need before we start rather than pricing around the gap.
Can you estimate both residential and commercial work in Fontana?
Yes. Fontana's construction mix includes single-family tracts, multifamily, and industrial and logistics buildings near the I-10 and I-15 corridors. Those scopes need different takeoff methods, so we keep them separate. Residential work is priced by assembly and by unit, while commercial and industrial work is priced by division with a full quantity survey. See our commercial estimating services and industrial estimating services for the scope each covers.
How do you handle Fontana's energy code requirements in an estimate?
The adopted energy code affects insulation values, window specifications, duct sealing, and lighting power density, and those items show up in the divisions where they are installed rather than as a single line. We price them from the plans and specifications, then flag anything that looks below the current code minimum. Confirm the adopted edition and any local amendments with the Fontana building department, because the applicable version changes on a state cycle.
What do you need from me to start a Fontana takeoff?
Send the complete plan set, the specifications, the geotechnical report if you have it, and any bid form or scope sheet from the owner. If there is a schedule or a phasing plan, include that too, because it affects general conditions and temporary facilities. Marked-up drawings showing what you are and are not bidding help us match your scope. You can get an estimate by sending the files through our quote request page.
Do you cover nearby cities in San Bernardino and Riverside counties?
Yes. We cover San Bernardino, Moreno Valley, and other cities across the Inland Empire, along with the rest of California. Soil conditions, wind exposure, and permitting offices vary between these cities, so we price each project against its own jurisdiction rather than applying one set of assumptions across the region. See our San Bernardino construction estimating page for the county seat and our California construction estimating page for statewide coverage.
What formats do you deliver?
We deliver Excel workbooks and PDF reports organized by CSI MasterFormat division, with marked-up plan sets showing the quantities we took off. The Excel file is structured so you can adjust waste factors, unit prices, or quantities without rebuilding the sheet. If your estimating software needs a specific import format, tell us before we start and we will match it where we can.
