Bishop Ranch by Sunset Development Company

What Bishop Ranch by Sunset Development Company does

Sunset Development Company is a family-owned, third-generation real estate developer founded by Masud Mehran in 1951 and led today by President and CEO Alex Mehran Jr. The company's principal asset is Bishop Ranch, a 585-acre master-planned mixed-use development in San Ramon, California, which it acquired in 1978 and has continuously operated since. Bishop Ranch comprises 5M square feet of Class A office space, 1M square feet of retail and entertainment anchored by City Center Bishop Ranch (opened 2018), two on-site hotels, civic infrastructure including San Ramon City Hall (2016), and a residential program scaling toward 8,000 homes via homebuilder partnerships with SummerHill Homes and KB Home, plus 177 units of senior living operated by Belmont Village.

Revenue is generated through four streams: recurring subscription-style leases on office and retail space to enterprise tenants (historically including Chevron and Pacific Bell's 7,500-employee relocation in 1985), one-time land/residential dispositions through homebuilder partners for housing, transaction-based venue rental bookings through booking.bishopranch.com, and ancillary amenity and event revenue. Distribution is hybrid: direct leasing historically, now supplemented by CBRE since December 2024, alongside homebuilder channel partnerships for residential and a self-serve venue booking platform. The $5B planned investment supports infrastructure build-out including a 23.9MW solar and storage portfolio deployed with DSD Renewables in 2024.

The company's competitive positioning rests on Tri-Valley geography with I-680 access, integrated live-work-play programming under a 15-minute lifestyle concept, and multi-decade family stewardship. Recent strategic moves include an office-to-residential conversion program (KB Home, March 2025), senior living expansion (Belmont Village, February 2025), the 2024 residential sales kickoff at City Village by SummerHill Homes, and the 23.9MW solar deployment. The development is privately held, family-owned, and operates with 101-250 employees, with no AI or proprietary technology capabilities disclosed.

Regional players

• Shea Homes: California-based homebuilder with operations in Northern California. Overlaps with the residential development strategy at Bishop Ranch, particularly for attached and master-planned product types.

Broad incumbents

• Toll Brothers: National luxury homebuilder with active Bay Area operations. Competes with the residential component of Bishop Ranch's City Village for premium home buyers in the Tri-Valley region.
• Vornado Realty Trust: Major office-centric REIT with a coastal focus on trophy assets. Overlaps with Bishop Ranch's premium Class A office leasing strategy though concentrated primarily in NYC and DC.
• Kilroy Realty Corporation: Bay Area-focused Class A office REIT (5M+ sq ft portfolio). Direct overlap with Bishop Ranch's 5M sq ft Class A office footprint and similar Tri-Valley/Peninsula tenant base.
• Boston Properties (BXP): Largest publicly-traded developer and owner of Class A office properties in the U.S., including significant Bay Area assets. Comparable in asset quality and tenant profile for the office component of Bishop Ranch.

Direct peers

• KB Home: Strategic partner and active buyer at Bishop Ranch ($57.8M office-to-residential acquisition, 190 planned homes). Comparable as a California-focused homebuilder competing for the same Tri-Valley residential demand.
