Room Addition Cost West Hollywood CA 2026 — Full Price Guide

Room Addition Cost Guide for West Hollywood, CA — 2026

West Hollywood room additions present a distinctive set of challenges and opportunities. WeHo is a small, densely built city where most residential properties are either multi-unit apartment buildings, condominium buildings, or single-family homes on tight 4,000–6,000 sq ft lots. Horizontal addition is often limited, but vertical addition (adding a second story or expanding upward) is highly viable in WeHo’s residential corridors. Home values range from $1.5M–$5M+ for single-family homes, with design expectations that reflect the city’s design-forward creative culture. APLA Construction (CA Lic #1136359) handles room additions throughout West Hollywood, managing City of West Hollywood permits and all construction.

West Hollywood Room Addition Costs by Scope (2026)

Scope 1: Bedroom or Home Office Addition ($88,000–$165,000)

What you get: Single-room addition of 150–240 sq ft at the rear or side of a WeHo single-family home. Foundation, framing, roofline, electrical, plumbing rough-in if needed. Finishes at WeHo design standards — not builder grade. City of West Hollywood plan check.

Best for: West Hollywood homes at $1.5M–$2.5M needing an additional bedroom or dedicated home office without major structural reconfiguration.

Scope 2: Primary Suite Addition ($168,000–$295,000)

What you get: Primary bedroom with attached primary bathroom and walk-in closet. WeHo design-market standards mean finishes must be genuinely attractive — clean lines, quality tile, frameless glass. At $2.5M–$4M WeHo home values, a primary suite addition is a high-ROI investment that can add $250K–$400K to resale value.

Scope 3: Second Story or Major Addition ($275,000–$495,000)

What you get: Full second story or large multi-room addition for a West Hollywood single-family home. Vertical expansion is the most common large addition path in WeHo given the tight lot constraints. Approximately doubles living square footage. City of West Hollywood plan check and structural review: 7–11 weeks for multi-story additions.
