Manhattan Beach is one of the most desirable coastal communities in California, with home values consistently among the highest in the Los Angeles metro area. ADU construction here delivers exceptional returns — a well-finished one-bedroom ADU in Manhattan Beach commands $2,800–$4,200/month in rent. APLA Construction (CA Lic #1136359) is a licensed ADU contractor building garage conversions, detached ADUs, and JADUs in Manhattan Beach.
Manhattan Beach has its own Building and Safety Department with a dedicated ADU permit track. Permit timelines for straightforward garage conversions run 5–9 weeks. Properties near the beach may be subject to additional coastal zone requirements. Manhattan Beach has its own design standards that APLA evaluates for each project at the start of planning.
Manhattan Beach’s ADU rental market is among the strongest in Southern California. A one-bedroom ADU commands $2,800–$4,200/month. A two-bedroom premium ADU can exceed $5,000/month. The payback period on a garage conversion ADU is typically 4–6 years — exceptional ROI by any standard. The coastal lifestyle, walkable downtown, and proximity to LAX and Silicon Beach employers drive relentless rental demand.

Building an ADU close to the ocean in Manhattan Beach requires attention to: marine-grade materials (corrosion-resistant fasteners, treated lumber, moisture-resistant sheathing), potential California Coastal Commission jurisdiction in some zones, and Manhattan Beach’s own design standards. APLA specifies coastal-appropriate materials for all Manhattan Beach ADU projects to ensure long-term durability in the salt-air environment.
A garage conversion ADU in Manhattan Beach costs $90,000–$158,000. A detached new-construction ADU runs $158,000–$315,000. These figures include design, City of Manhattan Beach permits, and all construction through Certificate of Occupancy. ADU rental income of $2,800–$4,200/month makes Manhattan Beach one of the best ADU ROI markets in California.
It depends on the specific property’s location within the Coastal Zone. Most Manhattan Beach properties are within the coastal zone, but not all ADU projects trigger Coastal Development Permit requirements. Interior garage conversions that don’t expand the building footprint typically don’t require a CDP. APLA evaluates coastal commission requirements for every Manhattan Beach property at project start.
