Known affectionately as “The City of Trees,” Tustin occupies one of the most strategic geographical footprints in Orange County. Bordering the corporate powerhouse of Irvine and the dense urban core of Santa Ana, Tustin acts as the ultimate commercial bridge.
For commercial property investors, Tustin is defined by a striking dichotomy. On one side, you have Old Town Tustin—a highly protected, historic downtown filled with century-old buildings, legacy restaurants, and boutique retail. On the other side, you have Tustin Legacy—the massive, ongoing 1,600-acre redevelopment of the former Marine Corps Air Station, featuring some of the most advanced creative office spaces and high-density mixed-use retail in Southern California.
Managing a commercial portfolio here in 2026 requires an incredibly wide operational bandwidth. You must know how to navigate strict historic preservation boards while simultaneously managing the complex environmental realities of a decommissioned military base. Whether you own a 1920s brick storefront on Main Street, a cutting-edge medical suite near The District, or an industrial flex warehouse on Red Hill Avenue, here is your definitive guide to maximizing your Net Operating Income (NOI) in Tustin.
Understanding Tustin Commercial Zoning & Specific Plans
Tustin does not rely on a simple, uniform zoning grid. The city’s economic future is heavily dictated by massive “Specific Plans” and strict historical overlays.
-
The Tustin Legacy Specific Plan: This is the most important zoning document in the city. It governs the massive acreage of the former military base. Zoning here is meticulously master-planned, divided into distinct “Planning Areas” that dictate ultra-specific requirements for creative office (like the FLIGHT campus), regional retail (The District), and high-density residential infill.
-
Old Town Commercial (OTC) & Historic Overlays: Properties within the boundaries of Old Town are subject to intense architectural scrutiny. The OTC zone encourages pedestrian-oriented, visitor-serving retail, but any exterior modification is fiercely regulated to protect the city’s early 20th-century aesthetic.
-
Planned Industrial (PM) & Light Industrial (M-1): Concentrated heavily in the southwest portion of the city (along Red Hill Ave and Edinger Ave), these zones protect the city’s vital logistics, manufacturing, and automotive sectors from residential encroachment.
-
General Commercial (C-2) & Retail / Services (C-1): These govern the traditional, auto-centric retail corridors stretching along 17th Street and Newport Avenue.
The Core Commercial Districts of Tustin
A property manager cannot treat an asset in Old Town the same way they treat a modern suite in Tustin Legacy. The tenant expectations and municipal regulations are worlds apart.
1. Tustin Legacy & The District
-
The Vibe: Massive scale, master-planned, and highly corporate. This area features massive regional shopping centers (The District) and cutting-edge creative office parks (like FLIGHT at Tustin Legacy, which features 18-foot ceilings, aviation-inspired architecture, and indoor/outdoor workspaces).
-
Management Focus: Maintaining Class-A corporate standards and managing intense traffic logistics. Tenants here (often tech, MedTech, and defense contractors overflowing from Irvine) demand pristine landscaping, EV charging infrastructure, and sophisticated building security systems.
-
2026 Outlook: Following the devastating 2023 North Hangar fire, the city and the Navy accelerated environmental cleanup efforts. In 2026, the release and redevelopment of the remaining hangar footprints and adjacent parcels is unlocking a massive new wave of commercial and mixed-use construction.
2. Old Town Tustin
-
The Vibe: A highly walkable, incredibly charming “Main Street USA” environment featuring historic Victorian and Craftsman architecture, award-winning restaurants, and local boutiques.
-
Management Focus: Historic preservation and parking management. Managing property here means dealing with aging plumbing, unreinforced masonry (URM) compliance, and navigating extreme parking deficits during the city’s popular weekend events and farmers markets.
-
2026 Outlook: Rents in Old Town remain at a massive premium due to sheer scarcity. The city is aggressively protecting this corridor from “chain” retailers, meaning property managers must curate authentic, high-quality local tenants to satisfy both the community and the municipal planners.
3. The Industrial Triangle (Red Hill / Edinger Corridor)
-
The Vibe: Gritty, functional, and highly lucrative. This is the heart of Tustin’s “blue-collar” economic engine.
-
Management Focus: Heavy utility oversight, roof maintenance, and industrial supply chain logistics. Properties here endure heavy wear-and-tear from 18-wheelers and manufacturing equipment.
-
2026 Outlook: Because Irvine’s industrial rents have skyrocketed, Tustin’s industrial sector is absorbing massive overflow demand. Landlords are buying older, functionally obsolete warehouses here, polishing the concrete, dropping in new HVAC, and executing highly profitable “value-add” flex conversions.
4. The 17th Street / Newport Ave Corridors
-
The Vibe: Traditional, neighborhood-serving retail strip centers and daily-needs shopping.
-
Management Focus: High-frequency CAM (Common Area Maintenance) repairs, security, and aggressive tenant retention in an era of e-commerce dominance.
2026 Market Trends: Environmental Reality & “The Irvine Alternative”
Tustin’s commercial market is being shaped by two massive macro-trends in 2026.
| The Catalyst | Impact for Commercial Owners |
| The “Irvine Alternative” Premium | Corporate tenants want the prestige and amenities of an Irvine office park without the Irvine price tag or the Jamboree Road gridlock. Creative office developments in Tustin are successfully capturing this “flight to quality,” allowing Tustin landlords to push rents aggressively on modernized office assets. |
| Base Realignment and Closure (BRAC) Compliance | If you are acquiring dirt or redeveloping property within the Tustin Legacy footprint, you are dealing with the legacy of the US Navy. Property managers and developers must navigate complex soil management plans, vapor intrusion mitigations, and strict environmental reporting before pulling building permits. |
| State Housing Mandates (RHNA) Infill | Like its neighbors, Tustin must rezone commercial land to meet State housing quotas. Aging retail centers along 17th Street and Newport Ave are prime targets for mixed-use redevelopment, drastically increasing the underlying land value for long-term hold investors. |
Compliance & The Historic Reality
You cannot successfully manage a property in Tustin without a deep understanding of the city’s localized code enforcement.
-
The Historic Resources Commission: If your building is in Old Town or on the local historic register, your hands are tied regarding exterior modifications. Everything from the style of the window mullions to the font on your tenant’s awning must be approved by the Historic Resources Commission. Attempting unpermitted work will result in immediate stop-work orders.
-
Conditional Use Permits (CUPs) for Dining: Tustin is highly protective of its residential neighborhoods bordering commercial zones. Securing a CUP for a new restaurant—specifically regarding late-night operating hours or a liquor license—requires extensive neighborhood outreach and acoustic studies to prove the business will not create a nuisance.
Why Local Tustin Management is Non-Negotiable
A generic management firm will treat a 1920s brick building on El Camino Real exactly the same as a 2024 glass-and-steel creative suite at FLIGHT. That lack of nuance will destroy your asset’s value.
