Room Addition Cost Glendale CA 2026 — Full Price Guide

Room Addition Cost Guide for Glendale, CA — 2026

Glendale room additions have become increasingly common as home values in the Verdugo Mountains foothill communities, Montrose, La Crescenta-adjacent Glendale, and the Brand Park neighborhoods have climbed to $1.5M–$3.5M+. Glendale’s housing stock — traditional mid-century ranch homes and bungalows on larger lots — is well-suited for additions, and the City of Glendale’s permit process is somewhat faster than LADBS for comparable scope. APLA Construction (CA Lic #1136359) handles room additions throughout Glendale, managing all City of Glendale permits and construction under one contract.

Glendale Room Addition Costs by Scope (2026)

Scope 1: Bedroom Only ($88,000–$162,000)

What you get: Single bedroom addition, 150–250 sq ft. Foundation, framing, roofline, electrical, insulation, finishes. City of Glendale plan check.

Best for: Glendale homes at $1.2M–$1.8M needing a bedroom count increase.

Scope 2: Primary Suite ($170,000–$310,000)

What you get: Primary bedroom (180–280 sq ft) with attached primary bathroom (65–110 sq ft) and walk-in closet. In Glendale’s traditional housing market, a primary suite addition is the single most impactful renovation for market position improvement — converting a dated 3/1 or 3/2 configuration to a 4/3 with proper primary suite.

Best for: Glendale homes at $1.5M–$2.8M where the primary suite is the main resale limitation.

Scope 3: Multi-Room Addition 600–900 sq ft ($305,000–$490,000)

What you get: Primary suite plus additional room(s). Or a family room extension with bedroom above. 600–900 sq ft of new living space. Glendale’s mid-century ranch homes on 6,000–9,000 sq ft lots often accommodate this scope well — sufficient rear setback and lot coverage allowance are frequently available.

Scope 4: Second Story Addition ($360,000–$640,000+)

What you get: Full second story above an existing Glendale ranch home. Approximately doubles square footage. Glendale hillside properties above Brand Blvd toward the Verdugo Mountains may require hillside-specific structural engineering for second story additions.
