Hermosa Beach room additions operate in one of the most compact residential footprints in the South Bay. The city’s signature narrow lots (25–30 ft wide typical) mean that horizontal additions are tightly constrained, but vertical additions — going up rather than out — are well-established in Hermosa Beach construction practice. A second or third story addition in Hermosa Beach not only adds square footage but frequently opens up ocean views that dramatically increase resale value. Home values range from $2M–$8M+ depending on proximity to the Strand. APLA Construction (CA Lic #1136359) handles room additions throughout Hermosa Beach, managing City of Hermosa Beach permits and all construction trades.
What you get: Single bedroom or home office addition, 140–220 sq ft. Rear or side addition on a Hermosa Beach lot. Foundation, framing, roofline tie-in, electrical, finishes. City of Hermosa Beach Building and Safety plan check included.
What you get: Primary bedroom with attached primary bathroom and walk-in closet at Hermosa Beach quality tier. Natural stone tile in bathroom. Walk-in shower. Heated floor. At Hermosa Beach home values of $2M–$4M, the primary suite addition is the highest-ROI structural investment available.

The most transformative addition type in Hermosa Beach — many properties gain partial or full ocean views at the second or third story level that simply do not exist at street level.
