Deck Builderin Desert Hot Springs, CA
A deck builder in Desert Hot Springs designs to a 130 mph residential wind speed with Exposure C, according to the Building & Safety Division, though a City wall standard says 95 mph and an old handout says 100. A detached deck of 200 square feet or less and 30 inches or lower needs no permit.
Desert Hot Springs grew up around soaking outdoors. The General Plan dates the first bath house to 1941 and says spas and resorts kept arriving for the next 20 to 30 years, and the Census Bureau's 2024 five-year estimates count 7,969 detached single-family homes, 63.9 percent of the city's 12,474 units. A deck here sits on a lot about 1,000 feet above the valley floor, in sun, wind and sand.
MDG Builders, CSLB #1040337, is a general contractor in Tarzana. We draw the deck, bring the wind, fire and permit questions to Building & Safety and hire a licensed carpentry subcontractor to build it. Materials and ranges are on the decks page, and the Desert Hot Springs overview lists the other trades we manage in town.
What Desert Hot Springs' Building & Safety Division, the Municipal Code, Riverside County Fire and state law say about decks
Where decks permits come from in Desert Hot Springs: City of Desert Hot Springs Community Development Department, Building & Safety Division.
- Decks: no permit is needed for a deck of 200 square feet or less that is not over 30 inches above grade at any point, is not attached to a dwelling and does not serve the required exit door (Work Exempt handout); anything attached to the house, higher or bigger needs a building permit.
- Patio covers: the City publishes a standard patio cover packet (June 2026 in its file name) with fill-in plot plan and worksheet: 3/8 inch by 5 inch lag bolts at 16 inches on center into the ledger, no OSB roof panels, 6 foot 8 inch minimum to 8 foot maximum clearance, footings at least 12 inches deep designed on 1,000 psf soil bearing, hurricane clips at 48 inches on center, and not designed to be enclosed (an enclosed cover needs extra engineering); two 2x members may replace one 4x member except in a high fire zone, where 2x joists are not allowed. Covers sit no closer than 10 feet to the rear property line (17.40.200, third-party mirror).
- Pools and pool decks (City pool plan check handout): a General B or C-53 contractor license is required to submit, owner-builder pool applications are not accepted, two stamped and signed engineered plans are required, and the handout promises comments within ten working days of a complete application; deck work must be dimensioned with positive drainage shown, and pool equipment sits at least 5 feet from the property line (17.40.200). The handout is a 2021 posting, so confirm it is current.
What wind speed does a Desert Hot Springs deck or patio cover have to be designed for?
The number to carry is 130 mph. The Building & Safety Division publishes a 130 mph residential design wind speed with Exposure C, seismic zone D, no snow load and Climate Zone 15 for plan preparers, and the General Plan says the funnel through the San Gorgonio Pass leaves the city more exposed to high wind than any other valley city.
Other numbers float around City paperwork. The free-standing block wall standard dated 07/18/2024 lists 95 mph, and an older plan check handout labels its truss item 100 mph. We read those as belonging to their own documents, not to a house, but any engineered design should state the wind speed it used, and the engineer should confirm it with the Division.
Wind is a hardware question. Ledger bolts, hold-downs, post bases and lateral ties carry the load, so ask the subcontractor to show the connection schedule and, for an attached cover, whether it is designed for uplift. The City's patio cover packet calls for hurricane clips at 48 inches on center.
How do 108 degree summers and desert sun change what a Desert Hot Springs deck is made of?
Heat and sun are the weather, and frost is a footnote. NOAA's normals at Palm Springs Regional Airport put the July average high at 108.6 F, count 114.8 days a year at or above 100 F and 0.3 days at or below 32 F, and the General Plan says the city regularly passes 100 degrees and occasionally 120. A deck here gets months of direct sun and almost no rain, 4.61 inches a year.
We found no local source on how hot a particular board gets underfoot, so ask each manufacturer for surface-temperature data and set a sample in the sun before choosing a color. Gaps and fastener spacing for expansion come from the maker's sheet, and the subcontractor should be able to show it.
Finish rules are guidelines, not deck rules. Section 17.08.070 says exposed wood should be stained rather than painted for desert durability and asks new homes to avoid reflective materials. Whether those lines reach a deck is a question for Planning, and the code text comes from GoCodebook's third-party mirror, so confirm it with the City.
Do you need a permit for a new deck or for deck repair in Desert Hot Springs?
A small, low, detached deck does not. The City's Work Exempt From Permits handout exempts a deck of no more than 200 square feet that is not over 30 inches above grade, is not attached to a dwelling and does not serve the required exit door. Anything attached to the house, higher or larger needs a building permit, and exempt work must still obey the code.
Repair is less clear. The handout's finish work list names no decking, so we found no City sentence that blesses even a few new boards. New framing, a new ledger, stairs or a taller guard are permit work, and photos sent to Building & Safety before the crew arrives settle the rest.
The process is online. Residential permits go through the City's OpenGov portal, an application with no permit issued in 180 days expires with one 90 day extension on written request, and starting early triggers an investigation fee equal to the permit fee. Deck permit fees are not published, so we quote none.
What do the City's patio cover packet and setback rules mean for a covered deck?
The City publishes a standard packet, dated June 2026 in its file name. It calls for 3/8 inch by 5 inch lag bolts at 16 inches on center into the ledger, bars OSB roof panels, sets clearance at 6 feet 8 inches minimum to 8 feet maximum, asks for footings at least 12 inches deep designed on 1,000 psf soil bearing and fills a plot plan and worksheet.
Setbacks come from zoning. Section 17.40.200 keeps a patio cover at least 10 feet from the rear property line, and Section 17.08.110 puts enclosed roofed accessory structures, patio covers among them, at least 10 feet from lot lines and no taller than the house, with gazebos, cabanas and shade sails at 5 feet and at most two enclosed accessory structures per single-family lot.
Enclosing a cover is a different job. The packet says the design is not meant to be enclosed, and an enclosed cover needs extra engineering, which is why a screen room or glass wall belongs in the first conversation, not the change order.
Is Desert Hot Springs a high fire zone, and does that change deck framing and boards?
We cannot give any lot a fire zone. Under a cooperative agreement with CAL FIRE, Riverside County Fire covers the city, and the 2024 Local Hazard Mitigation Plan says more than half of the city ranks moderate to high in fire severity. CAL FIRE's 2011 layer shows only two small Very High patches, and an April 2025 Idyllwild Town Crier report says the city's 26 Very High acres went to zero in the 2025 map. No City ordinance adopting that map turned up.
The City's patio packet still carries high fire zone framing: two 2x members may replace one 4x member, except that 2x joists are not allowed in a high fire zone. Ask Building & Safety which rule applies to the lot, and have the subcontractor price the heavier framing as an alternate.
Boards have their own list. The residential code's section R337.9.3 names decking surface materials allowed in wildland-urban interface areas, and one UC Extension summary said some tested composites did not meet the ignition-resistant definition, so check any product against the State Fire Marshal listing. Fire plans and permits go through the City's online portal, and paper plans are no longer accepted.
What do fault rules, pool plan checks and flood damage mean for deck footings here?
Footings answer to the ground. The patio packet assumes 12 inch deep footings on 1,000 psf bearing, while anything near the Mission Creek fault faces Section 17.40.090, which bars development within 50 feet of an active or potentially active fault, and Chapter 15.64, which asks for a geologist's report inside a State fault zone. Single-family wood-frame homes of two stories or fewer and minor additions are exempt from the report. We checked no parcel.
Pool decks have a handout. The City's pool plan check guide, a 2021 posting to confirm, requires a General B or C-53 contractor license to submit, refuses owner-builder pool applications, asks for two stamped and signed engineered plans, promises comments within ten working days and wants deck work dimensioned with positive drainage. Pool equipment sits at least 5 feet from the property line.
Water moves fast here. Tropical Storm Hilary closed the Little Morongo Road, Indian Canyon Avenue and Dillon Road crossings, and the Hazard Mitigation Plan says older areas without curb and gutter see low-lying damage and debris flow. Chapters 15.68 and 15.72 add flood-resistant construction rules in a mapped flood hazard.
What does a deck builder charge in Desert Hot Springs, wood or composite?
No Desert Hot Springs deck price study turned up, so the anchor is Remodeling magazine's 2025 Cost vs. Value report for Los Angeles. A 16 by 20 foot deck with a built-in bench, planter, three steps and full railing costs $18,419 in treated wood and recoups 99.6 percent at resale, and costs $26,872 in composite and recoups 73.9 percent. Angi's Los Angeles page of October 28, 2025 lists a $13,570 average inside a $6,335 to $20,871 range.
For planning we use $45 to $75 a square foot for pressure-treated wood and $65 to $110 for composite, which puts a 16 by 20 deck near $14,500 to $24,000 in wood or $21,000 to $35,000 in composite before permits and engineering. No independent source prices engineered or sloped-lot decks, so those wait for a visit. Federal data for May 2025 show Los Angeles area carpenters at a mean $37.79 an hour.
CSLB's C-5 class covers framing and rough carpentry, and a deposit may not exceed $1,000 or 10 percent of the price under Business and Professions Code 7159.5. Our license check guide shows how to read a record.

What decks costs around Desert Hot Springs
Dollar figures here are Los Angeles planning ranges from our decks page, not a Desert Hot Springs bid, and permits, engineering, soils work and any fire review belong on separate proposal lines. The same property may need flooring in Desert Hot Springs or concrete work in Desert Hot Springs. Desert neighbors to compare are decks in Palm Springs, decks in Cathedral City, decks in Palm Desert and decks in Indio, with decks in Los Angeles as the big-city benchmark. 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 Desert Hot Springs
Desert Hot Springs deck questions, answered
Do you need a permit to build a deck in Desert Hot Springs?
Often yes. The City exempts only a deck of 200 square feet or less, no more than 30 inches above grade, not attached to a dwelling and not serving the required exit door. Attached, taller or larger decks need a building permit. Call Building & Safety at (760) 329-6411 with the height, size and whether the deck touches the house.
How much would a 20x20 deck cost?
Using our Los Angeles planning figures, a 400 square foot deck lands near $18,000 to $30,000 in pressure-treated wood and $26,000 to $44,000 in composite, before permits and engineering. No desert study turned up. Height, stairs, railing length and soil work move the price more than square footage does.
How much should a 16x20 deck cost?
For Los Angeles, Remodeling magazine's 2025 Cost vs. Value report lists a 16 by 20 deck with bench, planter, three steps and railing at $18,419 in wood and $26,872 in composite. Our planning range is $14,500 to $24,000 in wood. These are Los Angeles numbers, so a desert proposal may differ.
Is it cheaper to build a wood deck or composite deck?
Wood costs less to build, at $18,419 against $26,872 for composite in the Los Angeles Cost vs. Value spec. Composite avoids some upkeep, but we found no local source on how hot dark boards get in 108 degree sun, so ask each maker for surface-temperature data before choosing.
Is railing height 36 or 42 for decks?
Use 42 inches. That is the minimum guard height in the 2022 California Residential Code, with openings small enough to stop a 4 inch sphere, where the walking surface is more than 30 inches above grade. The Division says the 2025 code governs applications from January 1, 2026, so confirm the numbers.
Does a 3 foot high deck need a railing?
Yes. A guard is required once the walking surface is more than 30 inches above grade within 36 inches of the edge, and 3 feet is 36 inches. The guard must be at least 42 inches tall in the 2022 text. Confirm the current edition and stair rules with the City.
What happens if a deck is built without a permit?
Starting before a permit triggers a special investigation and an investigation fee equal to the permit fee, on top of the permit fee itself, under Municipal Code 15.03.035. Ask the counter how a permit after the fact would work before you spend more.
Can I do deck repair in Desert Hot Springs without a permit?
Maybe for swapping a few boards, though no City sentence we read says so and the exempt list names no decking. A new ledger, new framing, stairs or a taller guard are permit work. Email photos to the counter before the crew starts.
What wind rating does a Desert Hot Springs deck cover need?
Design it to the 130 mph residential wind speed with Exposure C that the Building & Safety Division publishes. A City block wall standard lists 95 mph and an old handout says 100 mph for trusses, but those belong to their own documents. Ask the engineer to state the speed used.
What license does a deck builder need in Desert Hot Springs?
Wood decks are carpentry, so a general building license or the C-5 framing class is the usual answer for a deck builder. Look up the number on the CSLB site and ask each subcontractor for a license and certificate of insurance. Pool decks add a rule: the City requires a General B or C-53 license to submit a pool application.
