Deck Builderin Barstow, CA
A deck builder in Barstow works with a Building & Safety Division that lists Deck/Patio Cover as a permit category but shows no height or size threshold we could find, so call before assuming a low deck is exempt. Fire questions go to the Barstow Fire Protection District's Fire Marshal, not county fire.
Barstow grew around the railroad, with Route 66 following in 1926 and the City incorporating in 1947. Its housing is mostly small and old. The Census Bureau's 2024 five-year estimates count 10,017 homes with a median build year of 1970, 790 mobile homes and 56.3 percent renters, and the median home value is $245,000. A deck here is therefore often an add-on to a ranch house or a worn wood deck on a rental, priced against a modest house.
MDG Builders (CSLB #1040337) is a general contractor in Tarzana that draws, permits and manages the job while a licensed carpentry subcontractor builds it. We take permit and fire questions to the City's Building & Safety Division. Materials and ranges are on the decks page, and the Barstow overview lists the other trades we coordinate in the city.
What Barstow's Building & Safety Division, the Barstow Fire Protection District and state law say about decks
Where decks permits come from in Barstow: City of Barstow Community Development Department, Building & Safety Division.
- Decks, patio covers and shade structures: the Building Permit Application lists Deck/Patio Cover as a permit category; the Zoning Code lets a rear-yard shade structure attach to the house without extending it if open on three sides, lets open detached porches, gazebos and pergolas encroach into a street-side setback if 10 feet stays clear, limits rear-yard accessory buildings to one story, bars permit-requiring accessory buildings in required yards and bars accessory buildings that divert drainage onto neighbors (Sec. 19.24.050 and .060, mirror). The City's permit-or-not threshold for decks (height or size) was not found: unverified.
- Pools and spas (Sec. 15.08.040, mirror): any pool must be at least 5 feet from the main building and any lot line (unless specially designed) and the pool barrier top is 60 inches above grade (AG105.2.1 amendment); the Building Official can approve alternate safeguards. Swimming pool/spa is a Building Permit Application category.
Sources for these rules
Do you need a permit to build a deck in Barstow?
We could not find the City's height or size threshold. The Building Permit Application, revised June 2025, lists Deck/Patio Cover among its work categories and asks for the parcel number, floor area, setbacks, lot coverage, a construction valuation and the contractor's license number and classification. No page we read says which decks are exempt, so a low platform is a question for the Building Division, not an assumption. barstowca.org refused our requests, so we read its pages in Wayback Machine copies.
Submittal is on paper. Plans carry original wet signatures, and Building & Safety at City Hall is open Monday to Thursday from 8:00 a.m. to 5:30 p.m. and closed Fridays, at (760) 255-5179. The 2026/2027 Master Fee Schedule puts plan review at 65 percent of the building permit fee. An owner-builder must have lived on the site for 12 months, may use the exemption for two structures in three years and takes on every phase of the work once the permit is signed.
Hiring changes that. The City's plan checklist asks for business license verification for the general contractor and subcontractors, and the application asks for a workers' compensation certificate and whether the property is currently red-tagged. An open violation is worth settling before a deck is designed.
What do 100 degree days and desert wind do to a Barstow deck, and does deck repair need a permit?
Sun is the first test of any material. NOAA's 1991 to 2020 normals for the Barstow station show a July average high of 102.1 F, about 67.6 days a year above 100 F and 132.8 above 90 F, with a day-to-night swing near 30 F and only 4.96 inches of rain a year. We found no Barstow source on how wood, composite or its coloring behaves in that heat, so ask each maker for its heat, fading and warranty limits in writing.
Wind loads shade structures harder than flat boards. The Mojave Desert AQMD's Rule 403 defines High Winds as gusts above 25 mph or a 15-minute average above 15 mph, and the City's Housing Element says the land most prone to blow sand was zoned industrial. We did not find the City's design wind speed for homes, so ask the plan checker which one applies before an engineer sizes a patio cover, and ask how its posts are anchored against uplift.
Deck repair is the open question. No City page we read exempts it, so ask the Building Division when joists, a ledger, stairs or a guard are involved. Swapping boards on sound framing is a smaller step than replacing framing, and a deck that needed a permit to build still needs the same care to fix. Have the proposal say who inspects the framing once the old boards come off.
How deep are deck footings in Barstow, how high is the guard and how is a deck tied to the house?
We could not read the City's frost depth for footings. NOAA's station shows about 31.8 nights a year at 32 F or lower, mostly in December and January, so ask the plan checker to put footing depth and diameter on the drawing. Have the proposal say who digs, who calls the inspection and who pulls the permit. Inspections are booked by phone at (760) 255-5161.
Under the California Residential Code, a guard is required where the walking surface is more than 30 inches above grade within 36 inches of the edge, it must stand at least 42 inches tall, and its openings must stop a 4 inch sphere. The City's permit application says Barstow works under the 2022 California codes. We could not confirm that the 2025 codes, effective January 1, 2026, have been adopted, so ask which edition governs your plans.
A deck that attaches to the house hangs from a ledger. The 2022 code calls for a pressure-treated ledger of at least 2 by 8, flashed, fastened with hot-dipped galvanized or stainless hardware, with no beam loads bearing on it. Lateral loads are resisted by two hold-down devices of 1,500 pounds within 24 inches of each end, or four of 750 pounds. Those details come from the model code text, not from a City handout.
Which fire rules apply to a Barstow deck: the fire district, fire zones and fire pits?
Fire protection comes from the Barstow Fire Protection District, a combination fire district that the City administers, with its own fire chief and fire board. It is not San Bernardino County Fire, LA County Fire or Cal Fire. The District's page links Ordinance 30-2023, which adopts the 2022 California Fire Code, and the Community Development Director also serves as Building Official and Fire Marshal, reachable at (760) 255-5169.
Fire zones are an open question. The State Fire Marshal's recommended Local Responsibility Area table dated March 24, 2025 lists 13,031 acres of Barstow in the Moderate class and none in High or Very High, but we found no City or District notice adopting it, and the Safety Element still names wildfire in vegetated parts of the city and surrounding area. We therefore do not say that ember-resistant decking is or is not required at any address. Ask the Fire Marshal before choosing boards.
Fire pits matter on a patio deck. The District says store-bought fire pits need no permit, but self-built fire pits and backyard fireplaces need a permit and an inspection, picked up in person at no charge. Burning yard waste needs a free burn permit from the District's headquarters.
What changes when a Barstow deck sits beside a pool, under a patio cover or in a flood area?
A pool or spa beside a deck brings Sec. 15.08.040 of the Municipal Code, read in GoCodebook's third-party copy. A pool must sit at least 5 feet from the main building and any lot line unless specially designed, and the barrier top is 60 inches above grade under the City's amendment to appendix AG105.2.1. The Building Official can approve alternate safeguards, and swimming pool or spa is its own box on the permit application.
Shade structures follow Zoning Code Sec. 19.24.050 and .060. A rear-yard shade structure may attach to the house without extending it if it is open on three sides, open detached porches, gazebos and pergolas may encroach into a street-side setback if 10 feet stays clear, and rear-yard accessory buildings are limited to one story. None may divert drainage onto a neighbor. Single-family lots allow 45 percent lot coverage, so ask Planning how a deck counts.
Low lots add a floodplain question. The City Engineer reviews every development permit in a special flood hazard area, including whether the work is a substantial improvement, and the Housing Element discourages homes in flood-prone areas or asks that pads be raised above flood elevation. We did not check any address against the current map.
What does a deck builder charge in Barstow, wood or composite?
We found no study of Barstow deck prices that states its method, so the anchor is Remodeling magazine's 2025 Cost vs. Value report for Los Angeles. For a defined 16 by 20 foot deck with bench, planter, steps and railing it reports $18,419 in wood, recouping 99.6 percent at resale, and $26,872 in composite, recouping 73.9 percent. Angi's Los Angeles page of October 28, 2025 lists an average of $13,570 and a range from $6,335 to $20,871. Barstow's median home value of $245,000 is a reminder that Los Angeles resale percentages may not carry over.
Our planning ranges run $45 to $75 a square foot for pressure-treated wood and $65 to $110 for composite, which makes a 16 by 20 foot deck about $14,500 to $24,000 or $21,000 to $35,000 before permits and engineering. Repairs, engineered decks and decks on slopes wait for a site visit.
A wood deck is framing and rough carpentry under CSLB's C-5 class, and Business and Professions Code 7159.5 limits a down payment to $1,000 or 10 percent of the price, whichever is less. Our license check guide shows how to verify a CSLB number.

What decks costs around Barstow
Dollar figures on this page are Los Angeles planning ranges from our decks page, not a Barstow bid, so ask for permits, engineering, soils work and any fire plan review as separate lines. The same yard may also need flooring in Barstow or concrete in Barstow. Down the highway, compare decks in Victorville, decks in Apple Valley and decks in Hesperia, with decks in Los Angeles as the big-city benchmark. Adelanto has no page here yet. The subcontractor guide explains who frames and who finishes.

Barstow deck questions, answered
Can I build a deck without a permit in California?
For Barstow we could not confirm any exemption. The City's permit application lists Deck/Patio Cover as a category and we found no height or size threshold, so call Building & Safety at (760) 255-5179 first. We would treat an attached deck, a deck more than 30 inches high or a deck with a cover as a permit job until the Building Division says otherwise.
What happens if a deck is built without a permit?
You will likely need to apply after the fact, open framing for inspection and pay fees, and the Building Official can require changes. We did not read Barstow's penalty schedule, so ask the Building Division what applies. The permit application also asks whether the property is currently red-tagged, so an open violation can complicate a later permit.
Is railing height 36 or 42 for decks?
The California Residential Code sets the guard minimum at 42 inches, with openings small enough to stop a 4 inch sphere. A guard is required once the walking surface is more than 30 inches above grade. Barstow's permit application cites the 2022 California codes, so confirm the edition with the plan checker.
Does a 3 foot high deck need a railing?
Yes. Three feet is 36 inches, past the 30 inch height at which the residential code calls for a guard, and that guard must reach 42 inches with openings that stop a 4 inch sphere. A deck that tall is also something to put in front of the Building Division, since we found no exemption for it.
How much would a 20x20 deck cost?
A 20 by 20 foot deck is 400 square feet, so our planning range of $45 to $75 a square foot gives $18,000 to $30,000 in pressure-treated wood, and $65 to $110 gives $26,000 to $44,000 in composite. Those are Los Angeles figures before permits and engineering, not a Barstow bid.
Is it cheaper to build a wood deck or composite deck?
Wood costs less up front. Remodeling's 2025 Los Angeles report prices a 16 by 20 foot wood deck at $18,419 against $26,872 for composite, although composite recouped 73.9 percent at resale against 99.6 percent for wood. We found no Barstow data on heat and either material, so ask each maker for its warranty and heat limits.
Can I repair a deck in Barstow without a permit?
We found no City rule that exempts deck repair, so ask first when joists, a ledger, stairs or guards are involved. Replacing boards on sound framing is a smaller job than replacing framing, and the answer can depend on the deck's height. Call the Building Division at (760) 255-5179 with the scope before you buy lumber.
Does a Barstow deck need ember-resistant boards?
We could not determine that for any address. The State Fire Marshal's March 2025 recommended table puts 13,031 Barstow acres in the Moderate class and none in High or Very High, but we found no adoption notice. Ask the Fire Marshal at (760) 255-5169 which rules apply before choosing boards.
What license does a deck builder need in Barstow?
A current California license is required, usually a general building license or CSLB's C-5 class for framing and rough carpentry. Confirm the number on the CSLB site and ask each subcontractor for a license and certificate of insurance. The City's checklist also calls for a business license check on the general contractor and every subcontractor.
