General Contractor in Barstow, CA
Hiring a general contractor in Barstow means a City counter that takes paper plans with wet signatures Monday through Thursday, the Mojave Desert air district instead of South Coast, and its own fire protection district instead of a county agency. Most homes are older ranches, rentals and mobile homes. MDG Builders, CSLB #1040337, covers all eleven trades here.
Eleven trades, each written for paper plans, blow sand and 1950s ranch houses
Start with the job on your list. Every page leans on Barstow's own rules, marks the ones we could only verify through an archived City page or a code mirror, and keeps prices as regional ranges, never quotes.

Barstow began as Waterman Junction, a post office renamed on January 15, 1886 for William Barstow Strong, the Santa Fe railroad's president. The railroad itself arrived in 1888, and the Harvey House, Casa del Desierto, opened in 1911 and is on the National Register of Historic Places. Its unreinforced brick towers fell in the 1992 Landers earthquake and the City restored it. The business district was moved from the depot front to today's Old Town and celebrated on July 4, 1925, Route 66 was established in 1926, the Marine Corps Logistics Base followed on December 28, 1942, Victory Homes in 1943, and the City incorporated in 1947. That history explains the housing. Census estimates for 2020 to 2024 (ACS 2024 5-year, pulled through the Census Reporter API) count 10,017 housing units, give or take 468, with a median year built of 1970. About 64.0 percent of units predate 1980, the 1950s are the biggest decade at 25.0 percent, and only 7.4 percent predate 1950. Renters occupy 56.3 percent of homes, so many jobs here are a landlord updating a ranch house, duplex or fourplex, and the City's annual rental inspection program under Municipal Code Chapter 5.91 can enter the picture. Mobile homes are roughly 7.9 percent of units, with a wide margin of error. We did not research the build year of any single street, so ask before assuming one.
Permits are the City's job. The Building & Safety Division works out of City Hall, 220 E. Mountain View St., Suite A, and the counter line is (760) 255-5179, open Monday to Thursday from 8:00 a.m. to 5:30 p.m. and closed Fridays. The Community Development Director is also the Building Official and the Fire Marshal, so one office answers for building and fire plan review. Applications are paper with original wet signatures, and the plan checklist asks for three sets of plans plus a PDF on a flash drive, Title 24 energy calculations, a notarized letter of authorization from the owner, and business license verification for the general contractor and every subcontractor. We found no online permit portal except SolarAPP+ for rooftop solar. The City's site and the air district's site refused our plain requests, so each City and District fact here comes from a Wayback Machine copy with its snapshot date in the source link, and the Municipal Code comes from GoCodebook, a third-party mirror. Confirm any section number at the counter. Three conflicts matter. The City says it works under the 2022 California codes, the mirror still prints 2019 editions, and we could not confirm whether the 2025 codes have been adopted. The owner-builder page repeats a $500 license threshold, while a CSLB bulletin on AB 2622 puts the minor-work exemption at $1,000 from 2025. And the fiscal 2026/2027 fee schedule sets plan review at 65 percent of the permit fee, lists $24.82 at the current rate and $76.35 at the new rate for the first $500 of valuation, and gives a different May 2026 Council date than the Finance page does. Ask the Building Division for the fee on a real job.
Here is what each trade runs into. ADU construction has no City page, so the rules come from Section 19.10.070 in the mirror: ministerial approval within 60 days, a size cap of 75 percent of the existing living area or 1,200 square feet, and four foot side and rear setbacks, in text that may lag state law. A room addition on a single-family lot is held to 45 percent lot coverage, two stories and 10, 5 and 5 foot setbacks. Kitchen remodeling and bathroom remodeling ride on the form's Alteration, Plumbing, Mechanical and Electrical boxes, with a fixture list sent to Environmental Services when fixtures are added, and the permit form asks a lead-safe question for any home built before 1978. A roofing job has a reroof box with a square footage line but no size cutoff that we could find, and window replacement shows no exemption in the pages we read, so both are call-first jobs. Fence work follows Section 19.06.030: 6 feet in a rear yard, 3.5 feet in a required front or street-side yard, 4 feet if open chain link, and a permit for block walls over 3 feet and any retaining wall. Concrete touches the grading chapter and Engineering's encroachment permit at the street, though we found no City statement on flat patios. A deck falls under the Deck/Patio Cover category with no published height threshold. Painting and flooring installation are not permit categories on the form we read, yet the Mojave air district's Rule 1113 caps flat paint at 50 grams of VOC per liter, nonflat at 100 and floor coatings, garage floors included, at 100.
The ground and weather set Barstow apart from the valley cities. NOAA's 1991 to 2020 station USC00040521, 2.1 miles from the city point we use, records 4.96 inches of rain a year, about 68 days above 100 F, about 32 days with a low at or below freezing and a summer swing near 30 F between afternoon and night. Short storms run through the washes and the Mojave River channel, and the code mirror adopts a 1997 FEMA study with 1996 map sheets, so the City Engineer reviews floodplain questions. Two fault strips cross town. The Safety Element names the Barstow and Lenwood faults, each with a 500 foot Alquist-Priolo zone, while the Housing Element describes one zone inside the city and one next to it, so we report both and name no address. For air, Barstow sits in the Mojave Desert AQMD. Its Rule 403 bars visible dust beyond a property line except in high winds, which it defines as gusts above 25 mph, and it requires a District-approved Dust Control Plan on residential sites disturbing 10 or more acres. Fire service comes from the Barstow Fire Protection District, with its own chief and board, which lists Ordinance 30-2023 for the 2022 California Fire Code. Statewide mapping is a separate matter: the recommended 2025 table for San Bernardino County puts 13,031 acres of Barstow in the Moderate class and none in High or Very High, but no City or District adoption notice turned up, so no property gets a zone from us. MDG Builders, CSLB #1040337, writes the scope and files the paper set, hires licensed subcontractors for the field work and walks the finished job with you. The nearest hub cities are Apple Valley at about 25 miles, Victorville at about 29 and Hesperia at about 36, and Adelanto is about 30; each has its own counter. For the mechanics behind hiring, read how contractors use subcontractors and then checking a contractor license.

Barstow questions to settle before you hire a contractor
Does Barstow issue its own building permits?
Yes. The City's Building & Safety Division, part of the Community Development Department, reviews plans, issues permits and inspects, so San Bernardino County is not the permit office. Submittals are paper with original wet signatures, and the counter is open Monday to Thursday only. Confirm hours by phone, because we read City pages from archived copies.
Can I apply for a Barstow building permit online?
Not for most work, based on the pages we read. The forms page asks for hard copies with wet signatures plus a PDF on a flash drive, and the only online route we found is SolarAPP+ for residential rooftop solar. Pages may have changed since the archived copies, so ask the Building Division before planning around a portal.
Which air district rules apply to a Barstow project?
The Mojave Desert AQMD, not South Coast. Rule 403 forbids visible dust beyond the property line except in high winds and requires a District-approved Dust Control Plan on residential projects disturbing 10 or more acres. Rule 1113 caps coating VOC content. Both rules were read from archived Wayback pages, since the District's server would not answer us.
Who handles fire rules and burn permits in Barstow?
The Barstow Fire Protection District, which the City administers, with its own fire chief and board. It lists Ordinance 30-2023 adopting the 2022 California Fire Code, issues free burn permits and inspects self-built fire pits. It is not San Bernardino County Fire, and the Fire Marshal is the same official as the Building Official.
Is my Barstow home in a fire hazard severity zone?
We cannot say for any address. The state's recommended 2025 map table counts 13,031 acres of Barstow as Moderate and none as High or Very High, yet no City or District adoption notice turned up and nothing is classed parcel by parcel. Ask the Fire Marshal at (760) 255-5169 before assuming anything about your lot.
Why do so many Barstow remodels raise lead and old-house questions?
Because the housing is old. About 64.0 percent of units predate 1980 and the median year built is 1970, so the City's permit form asks a lead-safe question for any pre-1978 home. Owner-occupants can claim an exemption for their own residence, but landlords cannot. Testing old tile, mastic or plaster first is sensible, though it is not a permit rule.
Does Barstow have flood and earthquake risks I should ask about?
Yes, at the parcel level. The Mojave River and its washes flood after hard storms, including the evening of September 18, 2025, and the General Plan names two fault zones, described differently in two elements. We found no street-by-street map, so ask the City about your parcel before you design near a wash or river.
What does Barstow require from a general contractor?
A CSLB license number and classification on the permit application, plus business license verification for the general contractor and each subcontractor with the plan submittal. The owner-builder page warns that bids of $500 or more need a CSLB license, while a CSLB bulletin on AB 2622 sets the exemption at $1,000 from 2025.
