Room Addition Cost Guide for Studio City, CA — 2026

Studio City room additions are among the highest-ROI construction projects in the San Fernando Valley. Home values of $1.8M–$4M+ (and above $5M on Mulholland Drive) support room addition investments that consistently return more in resale value than they cost to build — while transforming the livability of some of LA’s most desirable residential properties. APLA Construction (CA Lic #1136359) handles room additions throughout Studio City, from the Ventura Corridor flatlands to the Mulholland hillside estates.

Studio City Room Addition Costs by Scope (2026)

Scope 1: Bedroom Only ($105,000–$190,000)

What you get: A single bedroom addition, 150–260 sq ft. Foundation, framing, roofline, electrical, insulation, drywall, flooring, windows, and finishes. LADBS plan check.

Best for: Studio City homes that need a bedroom count increase without bathroom reconfiguration.

Scope 2: Primary Suite (Bedroom + Bathroom) ($195,000–$355,000)

What you get: Primary bedroom (180–290 sq ft) with attached primary bathroom (65–110 sq ft) and walk-in closet. Full foundation, framing, roofline, MEP, and high-quality finishes. Studio City buyers at $2M+ expect primary bathrooms with heated floors, large walk-in showers, and double vanities — the suite finish level must match this expectation.

Best for: Studio City flatlands homes at $1.8M–$3M where the primary suite is the defining resale limitation.

Scope 3: Multi-Room Addition 600–900 sq ft ($340,000–$560,000)

What you get: Primary suite plus additional room(s). Or a family room extension with bedroom above. Adds 600–900 sq ft of finished living space. Appropriate for larger Studio City lots with sufficient setback clearance.

Scope 4: Mulholland Hillside Addition ($380,000–$850,000+)

What you get: Room addition on Studio City’s hillside properties above Ventura Boulevard. Hillside additions require soils engineering, grading permits, and hillside-specific structural systems. Material delivery and access logistics add cost. The result — new living space with canyon or city views — is among the most desirable residential improvements in Los Angeles.

Studio City vs. Sherman Oaks Room Addition Costs

Studio City room additions typically cost 10–20% more than equivalent Sherman Oaks additions due to: higher design expectations (entertainment industry homeowners expect premium finishes), more frequent hillside sites with higher structural costs, and stronger competition for experienced Valley trades. ROI is comparable or slightly higher in Studio City due to the stronger resale market.
