General Contractor in Fontana, CA

What should a Fontana homeowner know before hiring a general contractor, with Cajon Pass wind, a fire overlay and mostly post-1980 homes?

Fontana began as a farm town called Rosena. The City's history page says A.B. Miller bought 17,000 acres in 1905 and used 200 horses, mules, plows and scrapers to turn them into citrus orchards, poultry farms and cattle farms. The name changed to Fontana in 1913, and San Bernardino County's page on Miller dates it to June 7. Henry J. Kaiser opened the Kaiser Steel mill on the outskirts of town in 1942, and the City incorporated as a General Law city on June 25, 1952. The City says the mill ceased operation in 1984 while Wikipedia gives December 1983, so we state the year as disputed. Wikipedia's census table then shows the real story: 14,659 residents in 1960, 36,804 in 1980, 87,535 in 1990 and 128,929 in 2000. Census Bureau ACS 2024 one year estimates match it. They count 61,759 housing units, with a margin of error near 2,000, and only 22.9 percent of them (14,112) predate 1980. The 1980s hold 24.5 percent of today's units and the 2000s hold 20.9 percent. About 74.6 percent are single-family detached, 36.9 percent of occupied homes are rented, and the median owner-occupied value is $615,800. The table cannot split 1978 from 1979, so we never claim an exact count for EPA's pre-1978 lead rule. The oldest buildings cluster in the roughly one-square-mile downtown core around Sierra Avenue and Arrow Boulevard, where the Downtown Area Plan, adopted July 23, 2023, says inappropriate improvements have degraded many historic buildings. The Municipal Code lets the City designate historic overlay districts, but we found no list of designated properties, so ask Planning about any older address. We also could not verify how many homes sit under an HOA, so ask for the covenants before you draw anything.

The City issues its own permits. Building & Safety, part of Development Services at City Hall, 8353 Sierra Avenue, is open Monday to Thursday from 8 a.m. to 5 p.m., closed every Friday, and its number is (909) 350-7640. The Building & Safety page says applications still go in at the counter, though owners and contractors are encouraged to register on the Build Fontana portal to submit, pay and download plans. The Plan Check page puts a first review at about 3 to 4 weeks and later rounds at about 2 weeks. The residential alterations handout, revised January 8, 2026, requires a pre-alteration inspection before plans are accepted and four plan sets, or five when the work is over 250 square feet. Fire review is a separate door. The Fontana Fire Protection District, staffed by San Bernardino County Fire, reviews fire systems, access and hydrants with a 15 working day goal, is closed Fridays and does no over-the-counter review. Two rules apply to nearly every permitted job. Each application must carry a Construction Waste Management Plan showing at least 65 percent of debris diverted from landfill, and hauling from construction work goes through Burrtec Waste Industries, the City's franchise hauler, under Municipal Code 24-31(B). Work hours under Section 18-63(7) are 7 a.m. to 6 p.m. on weekdays and 8 a.m. to 5 p.m. on Saturdays, with no Sunday hours listed. The City's code hosts on Municode and AmLegal refused our tools and its Zoning Code page sat behind a Cloudflare challenge, so every Municipal Code section cited here comes from GoCodebook's third-party mirror, text as of October 4, 2026. The City adopted the 2025 California codes by Ordinance 1975 on October 28, 2025. Four water providers serve different parts of town, so ask which one serves your lot before any trenching.

What the counter wants depends on the trade. A roof repair or replacement is permitted work, non-classified roofing is banned citywide, and the City's handouts call for installation to 'High Wind' specifications. Window replacement has its own item in the City's fee schedule, so we treat it as permitted. For a kitchen remodel or bathroom remodel we found no City list of exempt work, so moving walls, wiring, plumbing or gas should be treated as permit work. Alterations over $1,000 trigger smoke and CO alarm upgrades, and at final the inspector checks fixture flow rates of 1.28 gallons per flush for toilets, 1.8 per minute for showerheads and 1.2 per minute for faucets. Fontana has required sprinklers in homes since 1987, so a remodel in a sprinklered house starts with a call to a licensed fire sprinkler contractor. Painting has no permit in anything we opened, but never paint over sprinkler heads or cover plates, South Coast AQMD Rule 1113 limits nonflat coatings to 50 grams per liter, and a street-facing block wall must be stuccoed or painted to match the house. On flooring, Rule 1403 covers asbestos in older tear-outs and Rule 1113 reaches garage floor epoxy and sealers. A fence needs no building permit up to 42 inches, side and rear fences stop at 6 feet, and wood is allowed only to replace an existing approved wood fence. Concrete has a 3 foot retaining wall exemption, a separate Engineering permit for a driveway approach in the public right of way, and Rule 403 dust control. We found no City exemption that names a deck, while a patio cover is its own permit item and sits outside the sprinkler rule. An ADU is a ministerial approval with 15 business days to check completeness and 60 days to decide, and the City offers three pre-approved plans. The City's ADU sheet and Section 30-467 disagree on attached ADU size, and a February 2026 notice mentions an amendment under Case 25-0080 whose text we did not open, so confirm the current rule. A room addition adds wind design, a Climate Zone 10 energy package and two different 50 percent tests.

Wind is what sets Fontana apart. The City's Wind and Storms page says Santa Ana winds accelerate through the Cajon Pass just north of town, with gusts in that corridor regularly above 60 miles per hour from roughly September through May, and northern Fontana the most exposed. Its handout tells designers to use 129 mph ultimate wind, Risk Category II and Exposure C. The mirrored wind table also carries a second row reading 135 mph that we could not interpret, so we use the handout's number. The October 2026 public review draft of the Local Hazard Mitigation Plan, still a draft with comments open through November 1, says Southern California Edison de-energized seven Fontana circuits in January 2025 for 18 to 98 hours and names the northern foothills, the west edge beside Rancho Cucamonga and the south edge beside Rialto and Bloomington as shutoff-prone areas. Fire rules came next. Ordinance 1972 designated the State Fire Marshal's recommended 2025 map, which the draft plan puts at 588 acres Moderate, 1,230 High and 4,088 Very High, and the draft dates the vote July 8, 2025 while the code history line reads 7-22-25. Under Section 30-656 of the Fire Hazard Overlay, an addition, alteration or reconstruction equal to 50 percent of a structure's existing square footage pulls the whole structure under the overlay's construction rules. We do not say which streets sit inside the overlay, and the Fire District's address-searchable map is the place to look. The ground matters too: the Cucamonga fault crosses the northern city, Alquist-Priolo zones touch the northern limits, and a lot sloped 10 percent or more needs a Hillside Development Permit. NOAA's 1991 to 2020 normals at Ontario International Airport give 11.64 inches of rain a year, while the draft plan quotes 24 to 27 inches for the whole city boundary, a gap we have not resolved. Zoning can also change: the City counts 27 Specific Plans that can replace base rules, so a call to Planning at (909) 350-6718 comes first. A permit answer from Rancho Cucamonga, San Bernardino or Jurupa Valley does not carry over, and neither does one from Ontario, Rialto or Colton next door. On a Fontana job, MDG Builders, CSLB #1040337, writes the scope, files the permit and books licensed trade subcontractors and inspections. Two reads help before you sign: how general contractors use subcontractors and how to check a contractor's license.
