Deck Builderin Redlands, CA
A deck builder in Redlands should treat any deck as permit work until Building & Safety says otherwise, because the City publishes no exempt low-deck threshold and its fee schedule has a deck line. The 2025 Wildland-Urban Interface Code applies citywide, and a historic district adds design review for street-visible additions.

Redlands' decks sit on two kinds of ground. The Census Bureau's 2024 estimates count 15,619 single-family detached homes, 56.8 percent of 27,483 units, and the City's wildfire plan says about 30 percent of the city lies in a high fire hazard severity zone, mostly the steep south and east around Smiley Heights, Live Oak Canyon and San Timoteo Canyon. In the older center, Victorian and Craftsman homes sit in eight local historic districts, so a rear deck on one street is a fire question and on another a design review question.
MDG Builders, CSLB #1040337, is a general contractor in Tarzana. We draw the deck, take the permit and fire questions to Redlands Building & Safety and hire a licensed carpentry subcontractor to frame it. The decks page covers materials and ranges, and the Redlands overview lists our other trades here.
What Redlands' Building & Safety Division, the Fire Department and state code say about decks
Where decks permits come from in Redlands: City of Redlands Development Services Department, Building & Safety Division.
- Decks and patio covers: the fee study prices a wood deck up to 200 square feet at $366 full cost (current $319.25) plus $293 per added 100 square feet, with calculations $439 up to 200 square feet and $512 over, and a city-standard wood patio cover at $292 (current $255.40); patio covers can be applied for in the City's online portal, and the City's pages read do not publish an exempt low-deck threshold.
- Decks in historic districts: unenclosed decks or covered patios of 200 square feet or less on a side or rear elevation and not visible from the public right of way are minor Certificate of Appropriateness items, while larger or street-visible additions are major.
- Balcony law for multifamily buildings: the City's January 2024 handout on SB 721 and SB 326 says buildings with three or more units having wood-supported balconies, decks, porches, stairways or walkways more than 6 feet above ground must be inspected (deadline January 1, 2025, then every 6 years, at the owner's cost) by a licensed architect, a civil or structural engineer, a general contractor holding an A, B or C-5 license with at least 5 years of multistory wood-frame experience, or a certified building inspector not employed by the City.

Can you build a deck on a historic street in Redlands?
Yes, if it stays small and out of sight. The City's Certificate of Appropriateness checklist, dated July 1, 2021, treats unenclosed decks or covered patios of 200 square feet or less on a side or rear elevation, not visible from the public right of way, as minor items that staff approve. Larger or street-visible additions are major items that go to the Historic and Scenic Preservation Commission. The certificate covers exterior work and new construction in the eight local districts and on designated landmarks.
Count the days. The Housing Element puts the process at about 45 days from a complete application to a public hearing, a 2022 figure, and the code says the building inspector issues the permit if the Commission has not acted within 60 days of submission. We quote no fees here because the City's fee pages carry more than one version.
Know which block you are on. The districts are Eureka Street, West Highland Avenue, Early Redlands, Normandie Court, East Fern Avenue, Garden Hill, La Verne Street and the Smiley Park Neighborhood, plus two National Register districts. North Redlands has none, though the Housing Element says it holds many homes over 50 years old. We did not open the boundary maps, so ask Planning at (909) 798-7555 ext. 1 whether your address is inside one.

What does Redlands' 2025 Wildland-Urban Interface Code mean for a deck?
It applies citywide. Municipal Code 15.30, adopted in 2025 and read in GoCodebook's third-party mirror, applies the 2025 California Wildland-Urban Interface Code in all areas of Redlands, names the Fire Department and Development Services as dual authorities and requires Class A roofs in Moderate, High and Very High zones. Hazardous fire areas need a 100 foot fuel modification zone, which can shrink to no less than 30 feet with approval for fire-resistive construction.
Defensible space sets what sits beside a deck. Existing buildings in High and Very High zones keep three bands: 0 to 5 feet ember-resistant with no organic mulch, 5 to 30 feet lean, clean and green, and 30 to 100 feet of fuel reduction, with tree branches 6 feet clear of roofs and combustible fences. A deck that touches the house sits in the first band, and the code text we read does not say how that band treats boards, rails or storage underneath, so ask the Fire Department at 909-798-7603.
We could not tell whether your lot is in a mapped zone. State law bars the City from ignoring the State Fire Marshal's updated zones in permitting, Municipal Code 15.30.120 designates the local zone by the map adopted with Ordinance No. 2986, and the State's map viewer returned an error. For decking, the 2022 California Residential Code (R337.9.3) lists allowed surfaces, and a University of California Extension summary said some tested composites missed the ignition-resistant definition, so check any board against the State Fire Marshal listing.

Do you need a permit to build a deck in Redlands, and how far can it reach into the yard?
Treat it as permit work. The City's Do I Need a Permit handout, from 2019 and not exhaustive, lists additions, alterations and patio covers and does not name decks, its fee schedule carries a wood deck line, and the pages we read publish no exempt low-deck threshold. The model residential code exempts only a deck of 200 square feet or less, not over 30 inches above grade, not attached to a dwelling and not serving the exit door (IRC R105.2, 2021 edition), and we did not confirm that Redlands keeps the line. The online portal takes patio covers but not decks.
Yard limits come from zoning. R-1 lots allow structures to cover 30 percent, keep a 25 foot rear yard and put accessory buildings on no more than 30 percent of the rear yard (Municipal Code 18.44). The City's ADU page cites 18.152.070 for projections into a rear yard: covered patios to within 5 feet of the line, stairways and balconies 4 feet, porches and landings 6 feet. Many lots sit in a specific plan with no Title 18 zoning, so Planning decides which standards apply.
A pool changes the rules. Municipal Code 15.06.070 requires a new or remodeled private single-family pool to have an isolation enclosure plus at least one more drowning-prevention feature from a list of seven, and a fence that serves as a pool enclosure is excluded from the 6 foot fence exemption. A deck beside water is a barrier question before it is a design question.

How is a deck anchored in Redlands, and how high must the guard be?
To the house wall carefully and to the ground for wind and shaking. The City's Structure Design Criteria handout, posted June 2025, lists basic wind speeds of 90, 96, 103 and 107 mph for Risk Categories I through IV, seismic design category D (E where a residential SDS exceeds 1.25), presumptive soil bearing of 1,500 pounds per square foot and a 1.5 inch per hour design rainfall. It cites 2022 code sections, so confirm the 2025 numbers at the counter.
Most deck failures start at the ledger. Section R507.9.1 of the 2022 California Residential Code (ICC copy) calls for a pressure-treated ledger of at least 2 by 8 with no beam bearing on it, none fastened to stone or masonry veneer, and hot-dip galvanized or stainless fasteners with flashing. Section R507.9.2 calls for lateral hold-downs, either two 1,500 pound devices within 24 inches of each end or four 750 pound ones. Redlands enforces the 2025 edition with amendments.
The guard answer is 42 inches. Section R312.1 requires a guard where the walking surface is more than 30 inches above grade within 36 inches of the edge, at least 42 inches tall, with openings that stop a 4 inch sphere, so a low deck needs none by that text. Wind is the other load: the Local Hazard Mitigation Plan notes gusts of 30 to 40 mph year-round and worse fire weather from August through October.

Can you build a deck on a hillside or canyon lot in Redlands?
Yes, but a 15 percent slope changes the process. The HD Hillside Development District (Municipal Code 18.138) covers any parcel averaging a 15 percent slope or with any slope of 15 percent or more, and it requires a slope analysis and plan certified by a registered civil engineer before clearing, grading or a building permit. It does not treat an addition of up to 1,000 square feet or 25 percent of the existing structure, whichever is greater, to a structure built before December 11, 1987 as development. We did not find whether a deck counts as an addition under that clause.
Canyon edges are where slope and fire maps overlap. The 2025 Community Wildfire Protection Plan puts the wildland-urban interface at Smiley Heights, Live Oak Canyon, San Timoteo Canyon and the eastern edge near Mentone and Yucaipa. Posts on a slope need a soil answer: Municipal Code 15.06.050 requires a geotechnical report for new construction or additions above 50 percent, and the Local Hazard Mitigation Plan rates landslide susceptibility low for the city overall but liquefaction high along the river, the Zanja and San Timoteo Creek.
Flood zones touch decks indirectly. Residential lowest floors in zones AE and AH sit 2 feet above base flood elevation under Municipal Code 15.32, and a remodel or addition reaching 50 percent of the structure's market value triggers the chapter. The pages we read are silent on decks there, so ask whether a large deck counts toward the total.

Can you do deck repair in Redlands without a permit, and what about termites and balcony inspections?
Swapping a few boards is upkeep, but no Redlands page says so. Because the City's pages give no deck exemption, send Building & Safety photos before the crew arrives and treat new framing, a new ledger, rebuilt stairs or a taller guard as permit work. The code withholds a permit when the site has open violations and charges an investigation fee equal to the minimum permit fee for work started without one, so a deck that came with the house should have its permit history checked before the repair, not during it.
Apartment owners have a separate duty. The City's January 2024 handout on SB 721 and SB 326 says buildings with three or more units whose wood-supported balconies, decks, porches, stairways or walkways stand more than 6 feet above ground had to be inspected by January 1, 2025, then every 6 years at the owner's cost. Inspectors include architects, engineers, qualified general contractors and certified building inspectors not employed by the City. Ask the City whether repairs that follow a report need a permit.
Wood has enemies here. University of California guidance says drywood termites are most common in southern California and infest decks and fences, so a repair should fix whatever keeps wood damp, and about 104 days a year at or above 90 F on NOAA's normals are hard on finishes. Rule 1113 sets VOC limits for stains and sealers and its posted table extracts out of order, so ask for the product's data sheet.

What does a deck builder charge in Redlands, wood or composite?
With no Redlands study to lean on, we use the Los Angeles figures in Remodeling magazine's 2025 Cost vs. Value report. In its spec, a wood deck of 16 by 20 feet with a bench, a planter, three steps and full railing costs $18,419 and recoups 99.6 percent at resale, and the composite version costs $26,872 and recoups 73.9 percent. Angi's Los Angeles deck page, dated October 28, 2025, shows an average of $13,570 inside a range of $6,335 to $20,871. Those resale numbers belong to Los Angeles, and the Census Bureau puts Redlands' median owner-occupied home at $613,600.
Our planning ranges are $45 to $75 per square foot for pressure-treated wood and $65 to $110 for composite, about $14,500 to $24,000 or $21,000 to $35,000 for 16 by 20 feet, before permits and engineering. Hillside, engineered and fire zone decks wait for a site visit, since no independent source prices them, and fire plan check, a soil report and any Certificate of Appropriateness belong on separate lines.
A wood deck is framing and rough carpentry under CSLB's C-5 class, so a general building contractor can take the job and hire the framer. Under Business and Professions Code 7159.5, a down payment cannot top $1,000 or 10 percent of the price, whichever is less. Our license check guide explains how to check a number.

What decks costs around Redlands
The dollar figures on this page are Los Angeles planning ranges from our decks page, not a Redlands bid, so permits, engineering, soil work and any fire plan review belong on separate proposal lines. A deck often pairs with concrete in Redlands or flooring in Redlands. For other Inland Empire cities, read decks in San Bernardino, decks in Fontana and decks in Ontario, with decks in Los Angeles as the big-city benchmark. For who frames and who finishes, see the subcontractor guide, and the kitchen remodel cost guide shows how we present sourced ranges.
| 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 |
Redlands deck questions, answered
Do you need a permit to build a deck in California?
In Redlands, treat any deck as permit work. The City publishes no exempt low-deck threshold and its fee schedule has a wood deck line. The model residential code exempts only a deck of 200 square feet or less, not over 30 inches high, not attached and not serving the exit door, and we could not confirm Redlands uses it.
How much should a 16x20 deck cost?
Our planning ranges give about $14,500 to $24,000 in pressure-treated wood and $21,000 to $35,000 in composite for 16 by 20 feet, before permits and engineering. Remodeling magazine's 2025 Cost vs. Value report for Los Angeles shows $18,419 for a wood deck with bench, planter and steps, and $26,872 for composite. Neither is a Redlands bid.
Is it cheaper to build a wood deck or composite deck?
Wood is cheaper to build. In the 2025 Cost vs. Value report for Los Angeles, a wood deck costs $18,419 and recoups 99.6 percent at resale, while composite costs $26,872 and recoups 73.9 percent. Composite saves staining, but check any board against the State Fire Marshal listing in a mapped Redlands fire zone.
Is railing height 36 or 42 for decks?
Forty-two inches under the 2022 California Residential Code, section R312.1, which requires a guard at least 42 inches tall where the walking surface is more than 30 inches above grade within 36 inches of the edge. Openings must stop a 4 inch sphere. Redlands enforces the 2025 edition with amendments, so confirm at the counter.
How high can a deck be without a railing in California?
Up to 30 inches above grade, by the 2022 California Residential Code text we read, which requires a guard only where the walking surface is more than 30 inches above grade within 36 inches of the edge. Redlands may amend that in its 2025 edition, so confirm, and a low deck can still need a permit.
Can you do deck repair in Redlands without a permit?
Probably for loose boards, but no Redlands page says so. New framing, a new ledger, rebuilt stairs or a taller guard should be treated as permit work. Send Building & Safety photos first at 909-798-7536, and ask for the permit history if the deck came with the house.
What happens if a deck is built without a permit?
The City can charge an investigation fee equal to the minimum permit fee, and it can withhold other permits while violations stand. Municipal Code 15.04.080, read in a third-party mirror, makes a building code violation a misdemeanor with a fine up to $1,000 and up to six months in county jail, each day a separate offense.
Does a deck in Redlands' wildfire zone need special decking?
The 2025 Wildland-Urban Interface Code applies citywide, and the 2022 California Residential Code (R337.9.3) lists allowed decking surfaces in interface areas. Whether your lot sits in a mapped zone is for the Fire Department at 909-798-7603, since we did not look up addresses. Class A roofs apply in Moderate, High and Very High zones.
What is the downside of composite decking?
Cost and resale. In the 2025 Cost vs. Value report for Los Angeles, composite costs $26,872 against $18,419 for wood and recoups 73.9 percent at resale against 99.6 percent. A University of California Extension summary also said some tested composites missed the ignition-resistant definition, so check boards in a fire zone.
What license does a deck builder need in Redlands?
A deck builder needs a California license, usually C-5 framing and rough carpentry, and a general building contractor can take the job and hire the framer. At the Redlands counter, a contractor pulling a deck permit shows a state license number and a workers' compensation certificate. Ask each subcontractor for a license and certificate of insurance.
