Deck Builderin Beverly Hills, CA
A deck builder in Beverly Hills starts with the lot: the Very High Fire Hazard zone covers the area north of Sunset Boulevard and a few blocks south, and the Central Area, Hillside Area and Trousdale Estates each set their own deck limits. The City's permit exemption list could not be read, so ask the Permit Center.
Decks here follow the hills. The Beverly Hills Hotel went up in 1911 to 1912 and the Virginia Robinson Estate in 1911, but Trousdale Estates came later: after Paul Trousdale bought the Doheny Ranch in 1956, its 410 acres were built mainly in the 1950s and early 1960s, according to Wikipedia's Beverly Hills article. Census estimates for 2020 to 2024 count 16,552 housing units, with 6,099 (37 percent) single-family detached homes and 8,522 of 14,449 occupied units (59 percent) rented, so many decks belong to a landlord or an association rather than an owner.
MDG Builders, CSLB #1040337, is a Tarzana general contractor that draws the deck, takes the zoning, fire and permit questions to the Permit Center and hires a licensed carpentry subcontractor to build it. Materials and ranges are on the decks page, and the Beverly Hills overview lists the other trades we run here.
What Beverly Hills' Zoning Code, Fire Department and Permit Center say about decks
Where decks permits come from in Beverly Hills: City of Beverly Hills Community Development Department, Building & Safety (Permit Center).
- In the Central Area, 10-3-2412 limits porches and decks on accessory buildings to no more than 3 feet above finished grade (an exception by Central R-1 permit is open to sites of 24,000 square feet or more). In Trousdale Estates, 10-3-2610C allows porches and decks at or below the first-floor level in side, street side and rear yards with handrails no more than 42 inches above that level, and front yard decks are not among the permitted encroachments.
- Under Article 50, ADU porches and decks may not be more than 3 feet above grade and rooftop decks on ADUs are prohibited, with no waiver available through a minor accommodation.
- The Fire Department's home hardening page recommends deck surfaces within 10 feet of the building be ignition-resistant, non-combustible or otherwise approved, and that combustibles be removed from under decks.
What decking is allowed in Beverly Hills' Very High Fire Hazard zone?
The City's FAQ says the Very High Fire Hazard Severity Zone covers the area north of Sunset Boulevard and a few blocks south of it, and the Fire Department inspects the zone on or after April 1 each year without appointments. A Beverly Hills Courier report says CAL FIRE's March 2025 maps designate about 260 additional acres as very high. We could not confirm how the City has adopted them, so check an address with the Fire Department.
For decks, the Fire Department's home hardening page recommends ignition-resistant, noncombustible or otherwise approved surfaces within 10 feet of the building, and removing combustibles from under decks. That page is guidance and names no code sections. The enforceable layer is the state's Wildland-Urban Interface code, which the City says took effect with the 2025 codes on January 1, 2026. Section R337.9.3 of the 2022 residential code lists allowed decking surfaces, such as products tested to ASTM E2632 or E2726 and fire-retardant-treated wood, and numbering may differ in the 2025 edition.
A UC Extension summary noted that some tested composites did not meet the ignition-resistant definition, so any board should be confirmed against the State Fire Marshal's listing, and we make no brand claims.
Do you need a permit to build a deck in Beverly Hills?
Not confirmed, and we will not guess. Municipal Code 9-1-107(B) lists exempt work, but the official code host blocked our automated reading. The model residential code exempts a deck of 200 square feet or less, not more than 30 inches above grade at any point, not attached to a dwelling and not serving the required exit door, and the Los Angeles County code exempts decks not more than 30 inches above grade. Whether Beverly Hills uses either text is unknown, so treat an attached, raised or hillside deck as permit-required until the counter says otherwise.
Rules about who may build apply too. A licensed contractor is required for any project valued at $1,000 or more, and owner-builder permits cover only owner-occupied single-family homes and, for interior work only, owner-occupied condos, so a deck on a condo exterior or a rental goes through a contractor. A building permit runs 365 days from the day it issues, and each passed inspection extends the expiration by 180 days.
Plan review depends on the lot. The July 2023 guide puts additions and remodels of single-family homes on a level pad in the intermediate electronic review group and Hillside Area ones in the complex group, so a deck reviewed as part of an addition on a slope should plan for the longer track. We print no review times.
How high can a deck be in a Beverly Hills yard, and does a slope change it?
It depends on the zone, and the numbers are tight. In the Central Area, Municipal Code 10-3-2412 limits porches and decks on accessory buildings to no more than 3 feet above finished grade, with an exception by Central R-1 permit open to sites of 24,000 square feet or more. Accessory buildings themselves must sit at least 100 feet from the front lot line or fully within 50 feet of the rear lot line, at least 6 feet from other buildings, and no taller than 14 feet in the accessory area. We did not read a Central Area height limit for a deck on the main house.
Trousdale Estates is more specific. Section 10-3-2610C allows porches and decks at or below the first-floor level in side, street side and rear yards, and front yard decks are not among the permitted encroachments.
On a Hillside Area lot, digging for footings counts toward the cut and fill budget of 1,000 cubic yards plus one-tenth of the site area over five years (10-3-2521), which also counts retaining walls and foundation work. This text comes from the GoCodebook mirror because the official host blocked access, so confirm it with Planning.
Do street-visible decks, ADU decks or pergolas face extra review in Beverly Hills?
Sometimes, and only in part of the city. In the Central Area, work visible from the public street, such as facade remodels and additions, needs some level of Design Review, and the City's Single-Family Regulations page adds new roofing. The pages we read name no deck threshold, so ask the Design Review planner about a street-side deck. Design Review does not reach Trousdale Estates or the Hillside Area.
A deck on an accessory dwelling unit has hard limits. Article 50 bars rooftop decks on ADUs, caps ADU porches and decks at 3 feet above grade and allows no waiver through a minor accommodation. The Planning Commission approved an ADU amendment on June 11, 2026, and the City filed a CEQA notice on August 17, 2026 for Ordinance Update 26-O-2940, so confirm the adopted text before drawing anything.
We found no Beverly Hills text on pergolas or patio covers. A roofed or attached structure changes both the permit and the fire questions, so bring it up at the first call.
Do you need a permit for deck repair in Beverly Hills?
Swapping worn boards is the simple case, but we found no City sentence calling a repair exempt, and the exemption list stayed unread, so ask the Permit Center. Rebuilding framing, a ledger, stairs or guards looks more like new construction. The 2022 residential code asks for a ledger of at least 2 by 8 pressure-treated lumber with no concentrated loads from beams or girders (R507.9.1.1), plus lateral hold-downs of two 1,500 pound devices within 24 inches of each end or four 750 pound devices (R507.9.2).
Tenants and pests come into repairs. Where a building is tenant-occupied and work could affect habitability for more than one day, a Means and Method Plan goes to the Rent Stabilization Ordinance Division before the permit issues. Termites are a regional risk too: UC's pest management guidance calls drywood termites most common in southern California, where they infest decks and fences, and advises fixing moisture problems and sealing exposed wood.
Noise has a clock. The City's FAQ allows construction from 8 a.m. to 6 p.m. on weekdays only, and Municipal Code 5-1-205 also restricts permit-required work on Saturdays near residential zones.
How high must a deck railing be in Beverly Hills, 36 or 42 inches?
Forty-two inches is the model minimum. The 2022 California Residential Code requires a guard where the walking surface is more than 30 inches above grade within 36 inches of the edge (R312.1.1), sets the minimum height at 42 inches (R312.1.2) and stops a 4 inch sphere from passing through any opening (R312.1.3). The code text is on ICC's site. Beverly Hills moved to the 2025 edition on January 1, 2026 with City amendments, and we did not compare section numbers or amendments.
On that model rule, a deck 3 feet above the ground needs a guard, because 36 inches is past the 30 inch trigger. In Trousdale Estates, the zoning code (10-3-2610C) limits handrails on permitted decks to 42 inches above the deck level, which appears to leave no room above the 42 inch minimum, so ask Planning before a taller glass or cable guard is drawn.
What does a deck builder charge in Beverly Hills, wood or composite?
No Beverly Hills price study turned up, so the anchor is Remodeling magazine's 2025 Cost vs. Value report. It defines a 16 by 20 foot deck with a built-in bench and planter, three steps and full railing, and prices it for Los Angeles at $18,419 in wood (99.6 percent recouped at resale) and $26,872 in composite (73.9 percent). Angi's Los Angeles page, updated in October 2025, lists an average of $13,570 and a range of $6,335 to $20,871. Wood is where the two sources overlap and composite is where they diverge, so we rate composite medium to low.
Our planning figures are $45 to $75 per square foot in treated wood and $65 to $110 in composite, which puts a 16 by 20 deck near $14,500 to $24,000 or $21,000 to $35,000 before permits and engineering. Federal data for May 2025 show carpenters in the Los Angeles-Long Beach-Anaheim area at a mean of $37.79 an hour, a wage and not a billing rate. Fire-zone surfaces, hillside footings and tenant paperwork can each add lines.
General contractors pay a Contractor's Business Tax Registration fee of 0.2125 percent of project valuation when the building permit is issued, and it covers their subcontractors. Plan review and permit fees depend on valuation and are worked out by appointment, so we print no fee amounts. CSLB's C-5 class covers framing and rough carpentry, and our license check guide shows how to look one up.

Beverly Hills deck questions, answered
Can I build a deck without a permit in California?
Only in narrow cases under the model code, and Beverly Hills' own exemption list in 9-1-107(B) could not be read. Treat an attached, raised or hillside deck as permit-required until the Permit Center says otherwise. A licensed contractor is required for any project valued at $1,000 or more, and a permitted job needs one even under that.
What is the largest deck without a permit?
Under the model residential code, 200 square feet, not more than 30 inches above grade, not attached to a dwelling and not serving the required exit door. Whether Beverly Hills adopted that exemption could not be confirmed, because the City's list was unreadable. Ask the Permit Center before building anything larger or attached.
How much should a 16x20 deck cost?
In Los Angeles, Remodeling magazine's 2025 Cost vs. Value report prices a 16 by 20 foot deck with bench, planter, steps and railing at $18,419 in wood and $26,872 in composite. Our planning ranges are about $14,500 to $24,000 and $21,000 to $35,000, with permits and engineering extra. No Beverly Hills study turned up.
Is it cheaper to build a wood deck or composite deck?
Wood costs less to build. Cost vs. Value's 2025 Los Angeles figures are $18,419 for wood and $26,872 for composite, though composite recouped 73.9 percent at resale against 99.6 percent for wood. In a fire zone, composite boards should be checked against the State Fire Marshal's listing, because some tested products did not meet the ignition-resistant definition.
Is railing height 36 or 42 for decks?
Forty-two inches is the model minimum in the 2022 California Residential Code (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. Beverly Hills adopted the 2025 edition with City amendments, which we did not compare, so confirm at the counter.
Do I need a permit for deck repair in Beverly Hills?
Replacing worn boards may not, but we found no City sentence that says so, so ask the Permit Center. Rebuilding a ledger, framing, stairs or guards is closer to new construction and likely needs a permit. In a tenant-occupied building, a Means and Method Plan may also be required before the permit is issued.
Which decking can I use in a Beverly Hills fire zone?
The Fire Department recommends ignition-resistant, noncombustible or otherwise approved surfaces within 10 feet of the building. The state code lists allowed surfaces, such as products tested to ASTM E2632 or E2726 and fire-retardant-treated wood. The zone covers the area north of Sunset Boulevard and a few blocks south, so confirm your address with the Fire Department.
Can I put a deck or roof deck on an ADU in Beverly Hills?
A rooftop deck on an ADU is barred, and porches and decks on an ADU may not be more than 3 feet above grade, with no waiver through a minor accommodation, under Article 50 as read on a code mirror. The ADU rules were being amended in 2026, so confirm the adopted text with Planning.
How high can a deck be in Trousdale Estates?
Municipal Code 10-3-2610C allows decks at or below the first-floor level in side, street side and rear yards, with handrails no more than 42 inches above that level, and front yard decks are not among the permitted encroachments. That text came from a third-party code mirror, so Planning should confirm it for your lot.
What license does a deck builder need in Beverly Hills?
CSLB's C-5 class covers framing and rough carpentry, and a general building contractor can take the job and hire the specialty trades. The City requires a licensed contractor for any project valued at $1,000 or more, with an agent authorization letter if the applicant is not the license holder. Check the number on the CSLB site.
