Costa Mesa Retail Space for Lease: 2026 Market Guide

Costa Mesa retail space for lease in 2026 spans one of the widest rent bands in Orange County — from roughly $1.75 per square foot on the industrial Westside to well north of $6.00 per square foot triple-net in the trade area around South Coast Plaza. A city of about 112,000 residents wedged between Newport Beach, Irvine, and Santa Ana, Costa Mesa punches far above its size: it is home to the highest-grossing shopping center in the United States and a cluster of design-driven districts that draw shoppers from across the region. For a tenant, that means the address you choose inside Costa Mesa matters as much as the city itself. We help operators read those differences before they sign.

How much does Costa Mesa retail space for lease cost in 2026?

Costa Mesa retail rents in 2026 generally run $2.25 to $4.50 per square foot per month on a triple-net basis for standard inline shop space, with prime South Coast Plaza–adjacent frontage and second-generation restaurant endcaps pushing past $6.00. Westside creative and flex conversions sit lower, near $1.75 to $3.00. Those are asking ranges; the number you actually pay depends on the corridor, the space size, and the tenant improvement package.

Because retail here is quoted almost entirely on a triple-net structure, base rent is only part of the equation. Estimated NNN charges — property taxes, insurance, and common area maintenance — add meaningfully to occupancy cost, and they vary widely between an enclosed regional mall and a small strip center. Understanding the difference between a gross versus NNN lease is the first step to comparing two Costa Mesa spaces honestly.

The South Coast Plaza and Metro Pointe corridor

Anchored at Bristol Street and the I-405, South Coast Plaza is the retail gravity center of Orange County, reporting well over $2 billion in annual sales and drawing luxury and international shoppers on a scale no other Southern California mall matches. Space inside the mall itself is tightly controlled and priced accordingly, but the surrounding trade area — Metro Pointe, Sakioka Drive, South Coast Collection frontage, and the Bristol Street pads — is where independent operators find opportunity. Expect asking rents from $4.00 to $6.50 per square foot NNN in this corridor, with the highest numbers on restaurant-ready endcaps and drive-aisle visibility. Tenants pay a premium here, but they buy access to a daytime and destination population that few Orange County corridors can rival.

17th Street, Eastside, and the neighborhood corridors

Along 17th Street and into Eastside Costa Mesa, the market shifts from destination retail to daily-needs and neighborhood service tenancy — boutique fitness, medical and dental, salons, coffee, and chef-driven independents serving Newport Heights and Eastside households. Asking rents on 17th Street typically run $2.75 to $4.25 per square foot NNN, with strong parking ratios and a loyal, high-income catchment. Newport Boulevard and Harbor Boulevard carry heavy traffic counts and suit larger-format and automotive-adjacent uses. For neighborhood retailers, the appeal is stability: these corridors turn over slowly and reward operators who become part of the community fabric.

SOCO, The CAMP, and The LAB: experiential districts

Costa Mesa pioneered the “anti-mall” concept, and it still leads Orange County in curated, design-forward retail. The LAB and The CAMP on Bristol Street, along with SOCO and The OC Mix on Hyland Avenue, built their tenant rosters around independent apparel, specialty food and beverage, wellness, and maker brands rather than national chains. Leasing into these centers is as much about fit as it is about rent — landlords curate tenant mix carefully, and a strong exclusive use position can protect a concept once it is in. If you are negotiating for one of these spaces, review how an exclusive use clause keeps a direct competitor out of the same center before you commit.

What NNN charges should you expect in Costa Mesa?

In 2026, estimated NNN charges on Costa Mesa retail space generally run $0.75 to $1.50 per square foot per month, though enclosed-mall and heavily amenitized centers can exceed that. A neighborhood strip center on 17th Street sits at the low end; a professionally managed lifestyle center with landscaped common areas, security, and shared parking structures sits at the high end. Always ask for the current-year estimate in writing and a look at the prior year's reconciliation. A space quoted at $3.00 base with $1.40 in NNN is not cheaper than a $3.75 space carrying $0.80 — a distinction we lay out in detail in our broader look at OC, LA, and Inland Empire NNN charges.

The Westside: Costa Mesa's creative and flex frontier

West of Newport Boulevard, the Westside has transformed from a purely industrial district into a magnet for breweries, roasteries, fitness studios, showrooms, and maker-retail hybrids. Former warehouse and flex buildings along Placentia Avenue, Victoria Street, and 19th Street lease from roughly $1.75 to $3.00 per square foot — often on modified gross or industrial-gross terms rather than pure triple-net. The trade-off is buildout: many of these spaces are shells or second-generation industrial, so a realistic tenant improvement budget and, where possible, a landlord allowance are essential. Our guide to negotiating a tenant improvement allowance walks through what to ask for and how to structure it. For concepts that need character and square footage over foot traffic, the Westside is Costa Mesa's best value.

Which Costa Mesa corridor fits your retail concept?

Match the corridor to the concept. Luxury, destination dining, and flagship retail belong near South Coast Plaza, where the rent premium buys reach. Daily-needs services, boutique fitness, and neighborhood dining thrive on 17th Street and the Eastside. Independent apparel, wellness, and specialty food find their audience in the curated SOCO, LAB, and CAMP districts. Production-driven and experiential concepts — breweries, studios, showrooms — get the most space and flexibility on the Westside. Costa Mesa is small enough to walk in an afternoon but diverse enough that the wrong corridor can quietly undercut an otherwise sound business plan. According to the U.S. Census Bureau QuickFacts for Costa Mesa, the city's median household income and daytime employment base both support a deeper retail market than its resident population alone would suggest.
