Deck Builderin Loma Linda, CA
A deck builder in Loma Linda starts with the lot's fire zone. The City's code requires decks in mapped hazardous fire areas to use decking at least 1.5 inches thick, or noncombustible material or a one-hour underside, unless the building director waives it. We found no published exemption for small decks, so ask the Building Division before you design.
Half of Loma Linda's homes went up before 1984. The Census Bureau's 2024 estimates count 4,673 single-family detached houses among 10,181 units, and the City approved The Groves at Loma Linda plan in 2018 for 1,067 more homes, so decks here are a mix of repairs on aging backyards and additions to newer tracts. Renters live in 62.1 percent of occupied units, and the southern third of the city is the South Hills, where fire and slope rules apply.
MDG Builders, CSLB #1040337, is a Tarzana general contractor. On a Loma Linda deck we draw the plans, put the zone and permit questions to the Building and Safety Division and the City's Fire Marshal, and hire a licensed carpentry subcontractor to frame and surface it. The decks page covers materials, the Loma Linda overview lists every trade we take here, and concrete work in Loma Linda covers the slab or footing side of a yard.
What Loma Linda's Building and Safety Division, its own Fire Marshal and state law say about decks
Where decks permits come from in Loma Linda: City of Loma Linda Community Development Department, Building and Safety Division.
- Deck standards: the City publishes a Deck/Balcony Building Standards handout with ledger bolting, joist span, post and knee-brace details, stairway width of 36 to 48 inches and a 36 inch minimum guardrail height, notes that shear walls cannot be modified without approved calculations, and says alternate engineered designs are allowed and the standard is used at the user's risk.
- Decks in fire zones: in the hazardous fire areas Municipal Code 15.32.020 requires cantilevered or standard decks to have at least one-and-a-half-inch thick wood decking or be incombustible or one-hour fire-resistive on the underside, and unenclosed wood stilt-type understructures to use 6 inch nominal members or one-hour protection; CBC Chapter 7A also applies in the designated WUI fire area. (Read in GoCodebook's third-party copy of the Municipal Code, text as of 2026-10-04, because the City's own code pages returned a Cloudflare 403.)
- Patio covers: the City's Patio Building Standards give conventional details (4x4 posts, 18 to 24 inch square by 12 inch deep footings depending on span, ledger bolting, 6 foot 8 inch minimum clearance, 30 inch maximum overhangs, tables for rafter, header and footing sizes), say the details are not valid for an enclosed patio without more engineering, and tell owners to check existing roof rafters for decay or termite damage first. Patio/Small Structure Review is $125 at planning (fee schedule), and the Building FAQ says simple patio covers are often checked at the counter the same day.
- Patio and carport zoning: attached, completely unenclosed rear patios may extend to 5 feet from the rear line in the R-1 table; carports must be fire rated, may not sit in the front or exterior side setback and may be 3 feet from side lines. (Read in GoCodebook's third-party copy of the Municipal Code, text as of 2026-10-04, because the City's own code pages returned a Cloudflare 403.)
Does a deck in Loma Linda's South Hills fire zones need special decking?
Yes in mapped hazardous fire areas, and the zone applies to the whole parcel. The State Fire Marshal's Local Responsibility Area map for Loma Linda, dated March 24, 2025, shows Very High, High and Moderate zones, and the City adopted them in Ordinance 785 on June 10, 2025. The stricter zone governs the entire parcel, a zone cannot be lowered and the City says it sends no notices to owners or insurers, so check the fire hazard map page and ask your insurer.
Municipal Code 15.32.020 sets the deck rule for one and two-family homes in the hazardous fire areas the fire chief maps. Cantilevered or standard decks need wood decking at least one and a half inches thick, or a noncombustible or one-hour fire-resistive underside, and unenclosed wood stilt understructures need 6 inch nominal members or one-hour protection. The building director may waive these where water supply and access are adequate. We read the code in GoCodebook's third-party mirror, so confirm current practice with the City.
Chapter 15.30 adopts the 2025 California Wildland-Urban Interface Code with Loma Linda changes and names the fire marshal as the code official, and 15.08.020 applies CBC Chapter 7A, ignition-resistant construction, throughout the WUI fire area the council designates. The pages we read give no acreage by zone and no parcel list. Loma Linda runs its own Fire Department, so these questions go to the City, not to San Bernardino County Fire.
Can you use a grill or fire pit on a deck near the Loma Linda South Hills?
Only a small propane one in wildland areas. The WUI Code's section A104.5, as amended by Loma Linda, allows only portable barbecues using one-pound propane supplies in wildland areas and in the listed City parks: Leonard Bailey, Hulda Crooks, Cottonwood, Elmer Digneo, Seamont and Ted and Lila Dawson. Fire Code 305.7.1 bans outdoor fires in fuel modification areas and adopted fire hazard severity zones without a permit from the fire code official, and 305.6 requires approved spark arresters on chimneys.
Vegetation around the deck counts as much as the boards. Fire Code 304.1.3 requires owners to cut and remove ignitable weeds, grass and vines, and in WUI areas clearance follows the state WUI Code and the Loma Linda Fire Department's vegetation management guideline. The Safety Element, a policy document rather than a code section, calls for fire agency review of new development and major remodels in High and Very High zones, Fire Protection Plans, defensible space and a retrofit program for existing development.
It also says new development or expansion should not go into Very High zones. A deck is not named in those policies, so ask the Fire Marshal whether a new or enlarged deck on a Very High parcel counts as a remodel. The Fire Department's administration line is (909) 799-2850.
Do you need a permit to build a deck in Loma Linda, and how close to the lot line can it go?
Plan on one, because we found no deck exemption. The Building FAQ says most buildings and structures need a permit, and the City publishes a Deck/Balcony handout rather than an exempt list. The model residential code exempts a detached deck of 200 square feet or less, not over 30 inches above grade and not serving an exit door, but we did not find Loma Linda adopting that line, so ask. Simple patio covers are often checked at the counter in a day or two, and complex work takes 15 to 30 working days, per the undated FAQ.
Setbacks come from the zoning table. The R-1 standards list a 25 foot front setback, side setbacks of 15 feet on one side and 5 feet on the other, a 15 foot rear setback, 10 feet between structures and a 35 foot height limit, and a completely unenclosed attached rear patio may reach 5 feet from the rear line. The City's Patio handout covers 4 by 4 posts, 18 to 24 inch square footings 12 inches deep, 6 foot 8 inch clearance and 30 inch overhangs.
Planning may add review. Patio/Small Structure Review is $125 on the fee schedule, and a Minor Precise Plan of Design decided by the Community Development Director applies to small accessory structures and to additions over 500 square feet, so ask whether a roofed deck counts. The Building line, (909) 799-2836, is staffed 8 to 10 a.m. Monday through Thursday, and City Hall is closed Fridays.
Can you repair a Loma Linda deck without a permit, and what about termites?
Swapping a few boards usually reads as maintenance, but no Loma Linda page says so for decks, so ask. The Building FAQ describes permits for structures, walls, pools and utility work and lists no repair line. The Deck/Balcony handout warns that shear walls cannot be modified without approved calculations, so a ledger repair that opens the house wall is not a board swap.
Termites and decay are the usual causes. UC Integrated Pest Management says drywood termites are most common in southern California and do infest decks, and it advises fixing moisture and sealing exterior wood. The City's Patio handout tells owners to check existing roof rafters for decay or termite damage before attaching a cover. Inside a mapped fire area, where a repair replaces much of the decking, ask whether the one and a half inch rule applies to the new boards.
Rental decks deserve care. Tenants occupy 62.1 percent of the city's homes, and the Housing Element says Code Enforcement complaints are mostly cosmetic, yet a rotted guard or stair is a safety item. The City's permit application also warns that a false exemption statement carries a civil penalty of up to $500 under Business and Professions Code 7031.5, so an owner should check any contractor's license before work.
How high must a deck guard be in Loma Linda, and how is a deck tied to the house?
The City's handout says 36 inches, and the state code says 42. Loma Linda's Deck/Balcony Building Standards list a 36 inch minimum guardrail height and stair widths of 36 to 48 inches, while the 2022 California Residential Code in our research sets guards at 42 inches in section R312.1.2, required where the walking surface is more than 30 inches above grade within 36 inches of the edge, with openings that stop a 4 inch sphere. The City adopted the 2025 codes in Ordinance 789, so ask the plan checker which number governs.
The ledger is the other critical detail. Section R507.9.1.1 calls for a pressure-treated ledger of at least 2 by 8, no beam loads on it and no attachment to stone or masonry veneer, and R507.9.1.3 wants hot-dipped galvanized or stainless fasteners with flashing. R507.9.2 asks for two 1,500-pound hold-downs within 24 inches of each end of the deck, or four 750-pound devices. The City's handout covers ledger bolting, joist spans, posts and knee braces, and allows alternate engineered designs.
Two major faults make lateral ties worth seeing on the drawings. The Safety Element places the San Jacinto Fault in the south of the city and the San Andreas about five miles northeast. Ask for hold-downs, ledger flashing and post bases as separate lines, and have them inspected before anyone covers them.
Can you build a deck on a South Hills slope or near the San Jacinto fault?
Yes in places, but an engineer comes first. Chapter 19.08 defines a hillside area as grade of 10 percent or more and requires a slope analysis by a civil engineer, and the HR zones require foundations to follow the natural slope where it is 15 percent or more. In the (H) suffix zone, development plans with grading, drainage and erosion control go to the Planning Commission, though the detailed standards skip one house and its accessory buildings on a parcel of record in 1974.
Geology is the second filter. The Alquist-Priolo zone follows the San Jacinto Fault in the south, the Safety Element calls for a geologic report before approval there and it places landslide risk in the southern badlands and the fault canyons. Footings for posts on a slope are where those reports show up, so ask what depth and distance from the slope face the engineer wants.
Water is the third. The Safety Element names San Timoteo Creek, Mission Channel and small hillside drainages as flood sources, which is why a deck's runoff path belongs on the plan. Measure V and Chapter 20.12 hold the southern hills to one home per 10 acres. Ask the Building Division whether a retaining wall under the deck needs its own permit, since the City says retaining walls do.
What does a deck builder charge in Loma Linda, wood or composite?
No Loma Linda deck price study states its method, so we anchor on Los Angeles sources. The 2025 Cost vs. Value report prices a 16 by 20 deck with built-in bench, planter, three steps and full railing at $18,419 in treated wood, recouping 99.6 percent at resale, and $26,872 in composite, recouping 73.9 percent. Angi's Los Angeles page, updated October 28, 2025, shows an average of $13,570 and a spread of $45 to $90 per square foot.
For a standard attached deck on flat ground we plan $45 to $75 per square foot in pressure-treated wood and $65 to $110 in composite, which works out to roughly $14,500 to $24,000 and $21,000 to $35,000 for a 16 by 20. Budget permits, engineering, soils work and any fire plan review on top, and expect hillside, second-story and exotic-wood decks to be priced after a site visit. BLS data for May 2025 show a mean of $37.79 an hour for carpenters in the Los Angeles area.
CSLB's C-5 class covers form work, framing and rough carpentry for framed structures, and the pages we read do not say which class covers composite surfacing, so ask each subcontractor which license applies. Business and Professions Code 7159.5 caps a down payment at $1,000 or 10 percent of the price, whichever is less, and our license check guide shows how to read a CSLB record.

What decks costs around Loma Linda
The dollar figures on this page are Los Angeles planning ranges from our decks page, not a Loma Linda bid, so permits, engineering, soils work and any fire plan review belong on their own proposal lines. Neighboring pages include decks in Redlands, decks in Colton, decks in San Bernardino, decks in Highland and decks in Rialto, with decks in Los Angeles as the big-city benchmark. A deck often travels with flooring in Loma Linda. The subcontractor guide explains who frames and who finishes.
| What it covers | Typical range |
|---|---|
| Pressure-treated wood deck | $45 to $75 per square foot |
| Composite deck | $65 to $110 per square foot |
| 16 by 20 foot wood deck (320 sq ft) | About $14,500 to $24,000 |
| 16 by 20 foot composite deck | About $21,000 to $35,000 |
| Hillside, second-story, rooftop and ipe decks | Priced by site visit |
| Permits and engineering | Quoted as separate lines |
Other work we manage in Loma Linda
Loma Linda deck questions, answered
Do you need a permit to build a deck in Loma Linda?
Plan on one. The Building FAQ says most structures need a permit, and we found no Loma Linda exemption for decks. The model code exempts a detached deck of 200 square feet or less, under 30 inches high and not serving an exit door, but the City has not been shown to adopt it. Call (909) 799-2836 with the size and height.
How much should a 16x20 deck cost?
For Los Angeles, the 2025 Cost vs. Value report lists a 16 by 20 deck with bench, planter, steps and railing at $18,419 in wood and $26,872 in composite. We plan roughly $14,500 to $24,000 for pressure-treated wood and $21,000 to $35,000 for composite, before permits and engineering.
Is it cheaper to build a wood deck or composite deck?
Wood costs less to build. Cost vs. Value's Los Angeles figures are $18,419 for wood, which recoups 99.6 percent at resale, against $26,872 for composite, which recoups 73.9 percent. Composite saves on staining later, but on a Loma Linda parcel in a hazardous fire area either material must meet the City's decking rule.
Is railing height 36 or 42 for decks?
The California Residential Code sets 42 inches, where the walking surface is more than 30 inches above grade within 36 inches of the edge, but Loma Linda's own Deck/Balcony handout lists a 36 inch minimum guardrail height. The two disagree, and the City adopted the 2025 codes, so ask the plan checker before building.
How high can a deck be without a railing in California?
A guard is required where the walking surface is more than 30 inches above grade within 36 inches of the deck edge, under section R312.1.1 of the 2022 California Residential Code. Below that height no guard is required by the code, though stairs have their own rules. Loma Linda's handout lists stair widths of 36 to 48 inches.
Can a wood deck be built in a Very High fire zone in Loma Linda?
Possibly, but the decking must meet the City's rule. Municipal Code 15.32.020 requires decking at least one and a half inches thick, or noncombustible material or a one-hour underside, in mapped hazardous fire areas, and CBC Chapter 7A applies in the WUI area. The Safety Element also discourages expansion in Very High zones, so ask the Fire Marshal.
Do I need a permit for deck repair in Loma Linda?
Ask before you start, because no Loma Linda page lists deck repair as exempt. Replacing a few boards is often maintenance, but ledgers, posts, stairs and shear walls are structural, and the City's handout says shear walls cannot be modified without approved calculations. Call the Building line between 8 and 10 a.m., Monday through Thursday.
What happens if a deck is built without a permit in Loma Linda?
The Municipal Code, read in a third-party mirror, doubles the fee for work started before a permit and sets a lesser charge for willful neglect, and neither excuses code compliance. We found no after-the-fact deck page, so ask the Building Division what it requires. Never claim a false exemption on the application.
Can I use a charcoal grill or fire pit on a deck in the Loma Linda South Hills?
Only a portable barbecue with one-pound propane supplies in wildland areas, under the City's amended WUI Code. Fire Code 305.7.1 also bans outdoor fires in fuel modification areas and adopted fire hazard severity zones without a fire code official's permit. Check the lot on the City's fire map before buying a fire pit.
What license does a deck builder need in Loma Linda?
A deck builder needs a current California license, usually a general building license or C-5 framing and rough carpentry. Anyone pulling a permit for a deck signs the City's license and workers' compensation declarations. Check the number on the CSLB site and ask each subcontractor for a license and certificate of insurance.
Tell us the height, the slope and whether the lot touches the South Hills
Say how high the deck will sit, whether the yard is flat or sloped, whether you live near the southern hills and whether this is a new build or a repair. We bring the fire map, the permit questions and the soil question to the first visit.
