Room Addition Contractor Redondo Beach CA — Costs & 2026 Guide

Room Addition Contractor in Redondo Beach, CA

Redondo Beach room additions are one of the most effective ways to create meaningful value on a South Bay property. With home values ranging from $1.2M in North Redondo to $4M+ in the Hollywood Riviera, adding a well-designed primary suite, family room expansion, or second story transforms both livability and resale position. Redondo Beach lots — particularly in the flatter areas of North and South Redondo — typically offer viable room addition opportunities that are constrained by setbacks but not by terrain. APLA Construction (CA Lic #1136359) handles room addition projects throughout Redondo Beach, managing all City of Redondo Beach permits and construction under one contract.

• Scope: Add 600–1,200 sq ft second floor with bedrooms, baths, and possible hallway. Requires structural reinforcement of existing first floor walls, new staircase, full-height sheathing, new roof. Second story is the most transformative (and most expensive) addition type in Redondo Beach.

Room Addition in Hollywood Riviera

Hollywood Riviera addition projects carry a premium for two reasons: First, the lots are often hillside or near-hillside, which adds structural complexity. Second, the home values ($2.5M–$4M+) support premium finish levels that increase per-square-foot cost. A Hollywood Riviera second story addition to capture ocean views typically runs $480,000–$900,000+ because of hillside structural requirements and the premium finishes appropriate for the neighborhood tier.
