Room additions in Studio City face a tighter floor area ceiling than most of the city. The Studio City Interim Control Ordinance sets a baseline of 0.33 FAR with bonuses up to 0.53, which is below the citywide BMO. Any addition has to fit within those caps. South of Ventura parcels are mostly in the BHO Hillside Area, adding height, setback, and lot coverage rules on top. Studio City has a strong concentration of architect designed Mid Century Modern homes, and additions to those properties carry an extra design responsibility. A poorly massed second story on a Mid Century home reads as wrong even when it technically conforms to code. Paradigm Builders coordinates feasibility, architecture, structural engineering, hillside design, ICO compliance, LADBS plan check, and LA City Planning entitlements through one office in Century City.

Our Room Additions Process
Every Studio City room addition runs through the same end to end process. Design, permits, and construction under one roof.
We walk your Studio City property to assess existing structural conditions, lot coverage, setback constraints, and zoning. Some lots will not support a second story. Some need foundation work first. We tell you up front what is buildable.
Floor plans, elevations, 3D renderings, and full structural engineering. We coordinate with surveyors, soils engineers, and the design team to deliver a permit ready package.
Line by line proposal covering site work, foundation, framing, exterior, MEP, finishes, and inspection fees. Allowances are real.
We submit the addition package to LADBS, manage plan check corrections, and coordinate any required HOA design review. Studio City ICO sets a baseline of 0.33 FAR with bonuses up to 0.53 FAR.
Excavation, footings, foundation pour, and any required structural retrofit on the existing house. Inspected before framing begins.
Wood or steel framing per engineering, roof tie ins, sheathing, dry in. The most visible week of any addition project.
Plumbing, HVAC, electrical rough through framing. Insulation. Pre drywall inspection.
Drywall, paint, flooring, doors, trim, fixtures. Final inspection and certificate of occupancy where applicable.
What a Room Addition Project Looks Like in Studio City
Three forces drive Studio City additions. First, the ICO FAR cap. The 0.33 baseline with bonuses up to 0.53 is a real ceiling and permits get extra scrutiny for compliance. We map FAR on day one. Second, BHO south of Ventura. Hillside parcels carry their own height, setback, and lot coverage rules in addition to the ICO. Third, architectural responsibility on Mid Century properties. The concentration of architect designed homes in the foothills means additions need to be massed and detailed with real care. View driven rooflines and creek adjacency along Tujunga Wash also constrain massing. We document each in the feasibility memo so owners can decide what is buildable.
Room Additions Permits in Studio City
Adding square footage in Studio City is a structural project. Permits, plan check, hillside or coastal review where applicable, and HOA approval where applicable.
Where the permits go. Addition plan checks in Studio City are handled by LADBS, LA City Planning, with structural review on every project.
Hillside, coastal, or seismic conditions. South of Ventura parcels mostly in BHO Hillside Area.
Code specifics. Studio City ICO sets a baseline of 0.33 FAR with bonuses up to 0.53 FAR. This is tighter than the citywide BMO. Permits in the ICO area get extra scrutiny for compliance.
Historic and design review. No HPOZ. Studio City operates under an Interim Control Ordinance (ICO) addressing mansionization.
Room Additions Cost in Studio City
Room addition pricing in Studio City typically opens in the low six figures for a modest ground floor expansion on a flatland parcel and runs into the high six and low seven figures for a meaningful second story on a hillside Mid Century or Spanish estate. Cost drivers include hillside foundation work, ICO compliance documentation, structural retrofit, retaining wall scope when applicable, and finish quality. We provide a written allowance schedule after a feasibility study.
Common Questions: Room Additions in Studio City
Can I add a second story to my Studio City home?
Often yes, but it depends on existing foundation, zoning height limits, lot coverage, and whether your area sits in a hillside or historic overlay. We do a feasibility walk before any design work to tell you what is buildable.
How long does a room addition take in Studio City?
Single story additions typically run 5 to 8 months total from design start to final inspection. Second story projects run 7 to 12 months. Hillside lots with grading or foundation retrofit add time.
Will I need to move out during the addition?
Depends on which part of the house is touched. Pure rear additions that are sealed off until tie in usually allow you to stay. Second story additions touching the roof typically require a short relocation during the most invasive weeks.
Do you handle structural engineering?
Yes. We coordinate the structural engineer of record, soils report if required, and any retrofit calculations. Engineering is part of the design package, not a separate scope you have to chase.
Can I match the existing exterior style?
Yes. We work with stucco, wood siding, brick veneer, stone veneer, and most LA area exterior systems. Color matching, texture matching, and aging existing stucco to blend with new is part of the finish trade.
What is the minimum addition size you take on?
We do bump out work as small as 80 to 120 square feet (closet, bathroom, kitchen pop out) up to whole house additions. The design and permit overhead is similar across sizes, so smaller projects pay a higher per square foot rate.
