Room Addition Cost Redondo Beach CA 2026 — Full Price Guide

Room Addition Cost Guide for Redondo Beach, CA — 2026

Redondo Beach room additions have become increasingly common as home values have climbed to $1.8M–$4M+ in North Redondo and the Hollywood Riviera. Redondo Beach’s housing stock — 1950s–1980s single-family homes on compact coastal lots — has strong demand for primary suite additions and second story projects that maximize the value of these properties relative to the South Bay market. APLA Construction (CA Lic #1136359) handles room additions throughout Redondo Beach, managing City of Redondo Beach permits and all construction under one contract.

Redondo Beach Room Addition Costs by Scope (2026)

Scope 1: Primary Suite — North Redondo ($185,000–$330,000)

What you get: Primary bedroom (180–280 sq ft) with attached primary bathroom (65–110 sq ft) and walk-in closet. Full MEP and premium finishes. In North Redondo Beach at $2M–$3M, the primary suite is the most ROI-positive single addition — converting a 3/1 or 3/2 home to a 4/3 with true primary suite often adds more in resale value than the construction cost.

Scope 2: Primary Suite — Hollywood Riviera ($210,000–$380,000)

What you get: Same scope as North Redondo, with a finish level premium appropriate for Hollywood Riviera’s higher home values ($2.5M–$5M+). Custom cabinetry in the walk-in closet, heated floors with stone tile, large-format shower. Hollywood Riviera buyers at $3M+ have design expectations that must be met at the suite level.

Scope 3: Multi-Room Addition 600–800 sq ft ($335,000–$540,000)

What you get: Primary suite plus additional room or family room expansion. Redondo Beach’s relatively compact lots (4,500–6,500 sq ft typically) require careful setback analysis before committing to multi-room scope. APLA provides free feasibility review. Some Redondo Beach lots, particularly in North Redondo, can accommodate this scope; others cannot.

Scope 4: Second Story Addition ($365,000–$640,000+)

What you get: Full second story above an existing Redondo Beach single-story home, maximizing square footage on a compact lot. Second story additions are particularly effective in Redondo Beach because they gain square footage without using lot coverage — the footprint stays the same but total living space roughly doubles. City of Redondo Beach plan check for second story: 5–8 weeks.

City of Redondo Beach Permits

Redondo Beach is an independent city with its own Building and Safety Department at 415 Diamond Street — NOT LADBS. Plan check for room additions: 4–7 weeks. APLA manages all City of Redondo Beach permit submissions and inspections.

Frequently Asked Questions — Room Addition Cost Redondo Beach CA

How much does a room addition cost in Redondo Beach in 2026?

Primary suite (North Redondo): $185,000–$330,000. Primary suite (Hollywood Riviera): $210,000–$380,000. Multi-room 600–800 sq ft: $335,000–$540,000. Second story: $365,000–$640,000+. Redondo Beach costs are comparable to Hermosa Beach and slightly below Manhattan Beach for equivalent scopes.

Is a second story addition the best option for Redondo Beach’s small lots?

Often yes. Compact Redondo Beach lots leave limited room for horizontal additions that maintain a usable rear yard. Second story additions add substantial square footage without sacrificing lot coverage or garden space — making them the preferred addition type on lots under 5,500 sq ft. APLA evaluates both horizontal and vertical options for every Redondo Beach addition project.

How long does a room addition take in Redondo Beach?

Primary suite: 5–9 months. Multi-room: 8–13 months. Second story: 10–17 months. City of Redondo Beach plan check: 4–7 weeks.
