Room Addition Cost Beverly Hills CA 2026 — Full Price Guide

Room Addition Cost Guide for Beverly Hills, CA — 2026

Beverly Hills room additions operate in one of the world’s most prestigious residential markets — home values of $5M–$50M+, estate properties with world-class landscaping and architecture, and buyers who compare their Beverly Hills home against comparable properties globally. Room addition investment at Beverly Hills values must reflect this standard: the addition must be architecturally seamless with the existing home, finished at the highest quality tier, and designed to add genuine estate value rather than simply square footage. APLA Construction (CA Lic #1136359) handles room additions in Beverly Hills, managing all City of Beverly Hills permits and construction under one contract.
