Diamond Parking Service

What Diamond Parking Service does

Diamond Parking Service is a privately-held, family-owned parking management company founded in Seattle in 1922 by Louis Diamond, recognized as the world's oldest operating parking company. The firm manages 2,200+ parking facilities across the United States and Canada, serving both enterprise B2B clients (hospitals, hotels, sports arenas, shopping centers, airports, residential properties, municipalities) and individual consumers through monthly permits and daily transient parking. Operations span 31+ regional offices and a multi-tier service portfolio that includes monthly parking, daily parking, event parking, valet services, garage management, hotel and hospital parking management, municipal parking, enforcement, revenue control, and consulting. Affiliated businesses extend the corporate footprint into Self-Storage, Boat World Marinas, and the United Parking brand, all under the Diamond Parking, Inc. corporate entity controlled by four generations of the Diamond family.

The core technology stack centers on two self-serve consumer platforms — PermitPoint (permitpoint.com) for finding parking locations and managing monthly parking accounts, and PayMyNotice (paymynotice.com) for paying and disputing parking citations. Operator-side capabilities include AI, License Plate Recognition (LPR), geo-targeting, mobile marketing, online reputation management, customer dashboards, and real-time sales tracking. The We Care Program offers complimentary roadside assistance (flat tire, jump start, fuel, lock-out) as a customer-experience differentiator.

Revenue is generated through four primary streams: monthly parking subscriptions (recurring), daily transient parking (transaction-based), parking notice fees with handling fees of $6.50 and total charges up to $150 including late fees up to $30 (transaction-based), and facility management services under management, gross, net, and fixed-lease agreements with property owners (managed services). The company is led by Joel Diamond (Chairman & CEO) and Jonathon Diamond (President), with Kathy Gatton as CFO and a deep regional management bench across US states and Canadian provinces. No institutional capital, public listing, or PE backing is indicated.

Emerging players

• SpotHero: SpotHero is an online parking marketplace aggregating inventory from operators like Diamond for consumer discovery and pre-booking. While not a direct operator, SpotHero shapes consumer demand and pricing dynamics that affect Diamond's daily/transient revenue stream.
• Metropolis Technologies: Metropolis is a VC-funded AI and computer-vision parking operator that acquires and modernizes legacy parking operators (including SP+). Represents the tech-enabled threat to Diamond's traditional model, deploying LPR and checkout-free technology that Diamond has begun adopting via its own AI/LPR roadmap.
• ParkMobile: ParkMobile provides mobile payment and enforcement technology widely used by municipalities and operators. Comparable to Diamond's PermitPoint and PayMyNotice platforms, and a potential partner or competitor depending on Diamond's white-label vs. proprietary tech strategy.

Direct peers

• Impark (Imperial Parking): Impark is a major North American parking operator with strong Canadian presence (headquartered in Vancouver, BC, like Diamond's Canadian HQ). Directly comparable on geography and full-service parking management for property owners across commercial, healthcare, and municipal segments.
• Towne Park: Towne Park is a major US parking and hospitality services company specializing in valet and self-parking management for hotels, hospitals, and resorts. Comparable in vertical mix, particularly hotel and hospital parking, where Diamond also focuses its valet and management offerings.
• LAZ Parking: LAZ Parking is one of the largest privately held parking operators in the US, managing thousands of facilities across multiple states with similar hospitality, healthcare, airport, and commercial focus. Closely comparable family-grown private operator competing for the same property-owner RFPs as Diamond.
• Republic Parking System: Republic Parking is a national parking management company with comparable service offerings (managed services, leasing, valet, enforcement). Direct competitor for the same property owner relationships, particularly in healthcare, hospitality, and commercial real estate.
• SP+ Corporation (now Plus Park): SP+ (now rebranded Plus Park) is one of the largest North American parking operators with thousands of facilities across the US. Comparable in scale to Diamond's 2,200+ facility footprint, with similar multi-vertical service portfolio covering airports, hospitals, hotels, and commercial real estate. Was publicly traded (and taken private by Metropolis in 2024), making it a close public-to-private comparable for Diamond.

Broad incumbents

• ABM Industries: ABM Industries is a large public facility services conglomerate whose parking division competes with Diamond across commercial real estate, healthcare, and airport segments. As a broad incumbent, ABM bundles parking with janitorial, HVAC, and other facility services, offering larger enterprise clients one-stop outsourcing versus Diamond's pure-play focus.

Regional players

• City Parking Management: City Parking is a regional operator focused on municipal, university, and hospitality parking in the Western US. Comparable mid-scale competitor for municipal contracts and university parking in the same geographies where Diamond operates.
