Deck Builderin Hemet, CA
A deck builder in Hemet can skip a permit only for a freestanding deck of 200 square feet or less, no more than 30 inches above grade, unattached to the house and not serving the required exit door. Raised decks beside one-story neighbors face privacy rules, and interface areas require noncombustible patio covers.
Hemet's decks go onto very different houses. The Census Bureau's 2024 estimates count 35,345 homes, among them 18,690 single-family detached, 1,944 single-family attached and 8,257 mobile homes, and the median home was built in 1984. General Plan 2030 says the Greater Downtown District grew from the late 1890s into the early 1930s with mostly one-story homes, so a raised deck is often next to a one-story neighbor, which is where Hemet's privacy rules begin.
MDG Builders, CSLB #1040337, is a general contractor in Tarzana. For a Hemet deck we write the scope, put the permit questions to the City's Building & Safety Division and manage the schedule, while a licensed carpentry subcontractor frames and finishes it. The decks page covers materials, and the Hemet overview lists the other trades we manage in the city.
What Hemet's Building & Safety Division, Planning, the Fire Department and state law say about deck work
Where decks permits come from in Hemet: City of Hemet Community Development Department, Building & Safety Division.
- A freestanding deck needs no permit in Hemet only if it is 200 square feet or less, no more than 30 inches above grade at any point, not attached to a dwelling and not serving the required exit door (Residential Code amendment R105.2) (text read in GoCodebook's verbatim copy of the Hemet Municipal Code, a third-party mirror updated 2026-10-19, because the City's own code page at hemetca.gov/104/Municipal-Code returned HTTP 403).
- Building & Safety posts city standard plans for balcony and deck permits and for residential patio covers (city and nationally approved designs).
- Inside the wildland interface standards, noncombustible material must be used on all patio coverings, overhanging members and columns must be noncombustible or covered with fire-resistant material, and stilt-built underfloor areas must be encased to the ground with exterior-wall standard materials (HMC 14-420) (text read in GoCodebook's verbatim copy of the Hemet Municipal Code, a third-party mirror updated 2026-10-19, because the City's own code page at hemetca.gov/104/Municipal-Code returned HTTP 403).
- Multi-story decks and modifications to existing multi-story decks fall under the second-story design and privacy planting criteria in HMC 90-315(g) (text read in GoCodebook's verbatim copy of the Hemet Municipal Code, a third-party mirror updated 2026-10-19, because the City's own code page at hemetca.gov/104/Municipal-Code returned HTTP 403).
How do Hemet's soils and 110 mph design wind change a deck's footings and framing?
Footings on this soil deserve a second look. The Public Safety Element says shrink-swell soils occur throughout Hemet, more in the east, that the condition is likely to affect building slabs, and that the City requires soil testing on new construction. A deck post set in the same clay can heave or settle, so ask the builder how deep the footings go, what lies under them and whether their size follows an engineer's drawing or a standard plan.
Wind is the other load. The City's design page gives 110 mph for Risk Category II at Exposure C, with 100 mph for Category I and 115 mph for Categories III and IV, and its Climate Vulnerability Assessment says Santa Ana winds frequently exceed 40 mph. Those numbers matter to roofs and pergolas and to a deck's connection to the house, so ask how posts, ledger and bracing resist uplift and sideways push.
Slopes are rarer but real. The Public Safety Element says slopes over 10 percent lie mostly on the periphery, in the Santa Rosa Hills, the Lakeview Mountains and Reinhardt Canyon, and the Hillside Development Overlay caps density from 4 units per acre on gentle slopes down to 0.5 above 25 percent slope, with the city engineer reviewing grading by slope band. A deck on a steep lot is a grading question first, so describe the slope when you call.
Can I build a deck without a permit in Hemet?
Only a small, low, detached one. A freestanding deck needs no permit in Hemet if it is 200 square feet or less, no more than 30 inches above grade at any point, not attached to a dwelling and not serving the required exit door, under Residential Code amendment R105.2 (read in GoCodebook's third-party copy of the municipal code, so confirm with the City). A deck bolted to the house fails the third test, and so does one that is 31 inches high at its tallest corner.
Building & Safety posts city standard plans for balcony and deck permits and for residential patio covers, which can shorten review when a design matches one. Since August 11, 2026 every new application goes through the Tyler EPL portal, and a permit lapses if work does not start within 12 months or stops for 180 days, though the building official can grant written 180 day extensions requested before expiry.
Skipping the permit has a cost. Code Compliance issues administrative citations for work done without approval, and the Plan Review page says work started before the City declares the job card and plans ready is treated as working without a permit and may draw a special investigation fee. The City's permit handout also lists patio covers, enclosed patios and any structural repair, so check before you assume.
Do Hemet's wildland interface rules change what a deck or patio cover can be made of?
Inside the interface areas, yes. HMC Article IX, Division 2 applies to the interface area and severity zones shown on exhibits kept at the City Clerk and Planning offices, and section 14-420 says noncombustible material must be used on all patio coverings, overhanging members and columns must be noncombustible or covered with fire-resistant material, and stilt-built underfloor areas must be encased to the ground with exterior-wall standard materials (third-party mirror, confirm).
Where those lines fall is the open question. The Public Safety Element says several Very High zones lie inside Hemet, all in Local Responsibility Area and in the southern half of the City, with the densest homes likely in Four Seasons on the eastern boundary above Route 74. The City's page calls CAL FIRE's 2025 zone maps proposed, so we cannot place a street in a zone. Ask Building & Safety whether your parcel is in an interface area or severity zone before choosing boards.
Existing homes can be touched as well. The code applies its landscaping and perimeter protection section (14-421) to existing development immediately, and its water supply and structural design sections apply to existing homes to the extent practical, as decided by the fire chief and building official, when work is done. The state's wildland-urban interface rule, R337.9.3 of the California Residential Code, lists allowed decking surfaces where it applies, so check any composite against the State Fire Marshal's listings.
What do Hemet's second-story privacy rules mean for a raised deck?
They treat a multi-story deck like a second story. HMC 90-315(g) applies its second-story design criteria to multi-story decks and to changes to existing multi-story decks, along with new multi-story homes and additions, when they sit next to existing single-story homes (third-party mirror, confirm). The upper level must sit within a 35-degree plane from the property line, or step back 15 feet, or step back two feet for every foot of height.
Screening follows. Side and rear windows need exterior louvers, obscure glass or sills five feet above the floor, and privacy trees of at least a 24-inch box size, 12 feet tall at planting, are recorded by covenant. Ask whether the builder has handled a deck review under this section, and whether the trees and the covenant are in the proposal and your budget.
A flat yard counts too. New single-family projects in Hemet must keep a flat usable rear yard equal to 5 percent of the lot area, which may not reach a deck on an existing house, so ask Planning how it applies. We did not read how the City counts decks toward that figure.
Is deck railing 36 or 42 inches, and what holds a deck to the house?
Forty-two inches. The 2022 California Residential Code, which Hemet's municipal code adopts with local amendments, requires a guard where the walking surface is more than 30 inches above grade within 36 inches of the edge, at least 42 inches high, with openings that stop a 4 inch sphere (R312.1). The mirror still says 2022 and we found no local adoption of the 2025 cycle, so ask which edition governs your permit.
The ledger is where many decks fail. Under R507.9 it is at least a pressure-treated 2x8, carries no concentrated loads from beams or girders, is not fastened to stone or masonry veneer, uses hot-dipped galvanized or stainless fasteners and is flashed, and lateral hold-downs are two 1,500 pound devices within 24 inches of each end or four 750 pound devices.
A pool changes the barrier question. HMC 90-316(8) requires a swimming pool to be completely enclosed by buildings, fences or walls, with the required fence or wall in place and approved by the building department before the pool is filled (third-party mirror), so a deck beside a pool needs a plan for the barrier.
Can deck repair in Hemet happen without a permit?
Cosmetic repair, yes; structural repair, no. The City's permit handout lists any electrical, plumbing, mechanical or structural repair, so replacing worn boards on sound framing is a different job from replacing a rotted ledger, post or joist. Ask the builder to photograph the framing before pricing, and describe what is found to Building & Safety if a post, joist or ledger is rotted.
Old decks have a calendar. Hemet has 13,380 homes from the 1950s through the 1970s (1,599, 4,114 and 7,667 by decade), so a deck that came with the house is at least 47 years old. Check the ledger connection first, then the footings, then the guard height, since an older guard may sit below 42 inches.
Mobile home decks sit under park rules. Hemet enforces the state Mobilehome Parks Act, and its Bulletin 109 sets separations of 3 feet to a lot line and 10 feet to a permanent building with a 75 percent maximum lot coverage, and 6 feet to permanent buildings in parks built before September 15, 1961. We did not read how those separations treat decks, so ask the City and the park before building.
What does a deck builder charge in Hemet, wood or composite?
We found no Hemet deck price study, so the anchor is Remodeling magazine's 2025 Cost vs. Value report for Los Angeles. Its 16 by 20 foot deck with bench, planter, three steps and full railing costs $18,419 in wood, recouping 99.6 percent at resale, and $26,872 in composite, recouping 73.9 percent. Angi's Los Angeles deck page of October 28, 2025 reports a $13,570 average, with most projects from $6,335 to $20,871. Those resale figures belong to Los Angeles and may not carry to Hemet.
Los Angeles planning figures on our decks page run $45 to $75 per square foot for pressure-treated wood and $65 to $110 for composite. For a 16 by 20 deck that is about $14,500 to $24,000 in wood or $21,000 to $35,000 in composite, before permits and engineering. No independent source prices hillside, fire-area or engineered decks, so those wait for a site visit.
A deck is framing and rough carpentry under CSLB's C-5 class, and permitted work needs a licensed contractor at any price. Business and Professions Code 7159.5 holds a down payment to $1,000 or 10 percent of the price, whichever is less, and our license check guide shows how to verify a number.

Hemet deck questions, answered
Do you need a permit to build a deck in Hemet?
Yes for most decks. Hemet exempts only a freestanding 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. Any attached deck, any higher or larger deck, or a deck that serves the exit door needs a permit. Confirm with Building & Safety at (951) 765-2475.
Is railing height 36 or 42 for decks?
Forty-two inches is the minimum guard height in the California Residential Code, with openings that stop a 4 inch sphere. The code asks for a guard once the walking surface sits more than 30 inches above grade within 36 inches of the edge. Ask the builder which edition of the code your permit uses.
Does a 3 foot high deck need a railing?
Yes. A 3 foot deck is 36 inches above grade, which is more than the 30 inch trigger in the California Residential Code, so it needs a guard at least 42 inches high. That height also pushes the deck past Hemet's 30 inch permit exemption, so the deck needs a permit as well.
How much should a 16x20 deck cost?
Remodeling magazine's 2025 Cost vs. Value report for Los Angeles puts a 16 by 20 foot deck with bench, planter, three steps and railing at $18,419 in wood and $26,872 in composite. Our Los Angeles planning figures give $14,500 to $24,000 in wood and $21,000 to $35,000 in composite. Hemet bids may differ.
Is it cheaper to build a wood deck or composite deck?
Wood costs less up front. Cost vs. Value for Los Angeles shows $18,419 in wood against $26,872 in composite, but wood recouped 99.6 percent at resale and composite 73.9 percent. Upkeep and fire-area rules are separate questions, and in a Hemet interface area the board must meet the decking rules that apply to the parcel.
What happens if a deck is built without a permit?
In Hemet, Code Compliance issues administrative citations for work done without approval, and the Plan Review page says work started before the City declares plans ready is treated as working without a permit and may draw a special investigation fee. Ask Building & Safety how to bring an existing deck into compliance.
Can I repair a deck in Hemet without a permit?
Cosmetic deck repair, such as replacing worn boards on sound framing, usually does not need one, but the City's permit handout lists any structural repair. A rotted ledger, post or joist counts. Photograph the framing, describe what you find to Building & Safety, and ask before work starts.
What license does a deck builder need in Hemet?
A deck is framing and rough carpentry, so a deck builder needs a current California license, usually C-5 or a general building license, and any permitted deck needs a licensed contractor. Check the number on the CSLB site and ask each subcontractor for a certificate of insurance. We found no Hemet deck-specific license rule.
Can I build a second-story deck next to a one-story neighbor in Hemet?
Possibly, but HMC 90-315(g) treats a multi-story deck like a second story next to an existing single-story home. The upper level must sit within a 35-degree plane from the property line, or step back 15 feet, or two feet for every foot of height. Screening and privacy trees may be required.
