Level 3 Construction, Inc. is a San Diego-based general contractor trusted by leading developers, global hospitality brands, real estate investors, architects, and community partners to bring their visions to life. We specialize in the ground-up construction and renovation of multifamily housing, hotels, mixed-use developments, affordable/workforce housing, senior living, and student housing.
Under the leadership of Founder Ian Mahon, our in-house trades team brings technical expertise, budget discipline, and design fluency to every project, ensuring construction excellence and predictability. By taking a hands-on, collaborative approach, we combine efficiency, exceptional quality, and attention to detail to create spaces that inspire and communities that thrive.
While most of Level 3 Construction’s projects are concentrated in San Diego County, we’re able to mobilize our team quickly and tap into our vast network of highly vetted subcontractors to deliver ground-up construction and renovation projects throughout Southern California. Whether you’re building out an apartment complex, renovating a hotel to meet new brand standards, or converting an office space to affordable housing, we will be your strategic partner – bringing predictability, transparency, and responsiveness to your project.
For us, general contracting means we expertly manage all phases of construction. This includes early consultations with our management team, pre-construction planning and logistics, workforce coordination, trade performance, quality assurance, budgeting, scheduling, compliance with partner and city stakeholders, and final project delivery. We combine deep in-house trade expertise, rigorous cost control, and proactive scheduling to ensure that the projects we manage achieve the design that our clients envision – each and every time. Contract with us, and you can be assured that throughout your project’s lifecycle, we’ll operate as a strategic partner to maintain financial discipline and meet, even exceed, stated delivery timelines.
Our passion is building, and we are proud of the projects we’ve built over the years. Here are just a few examples of our recent projects:
- Multifamily: Punta Lara – By The Bay – San Diego
A striking example of design-forward multifamily living, Punta Lara – By The Bay is a 24-unit apartment community in Point Loma that earned an architectural award nomination upon completion. This project exemplifies our ability to blend thoughtful design with superior construction in a vibrant San Diego neighborhood.
- Mixed-Use: SALT – Oceanside
SALT is a ground-up, mixed-use development in downtown Oceanside featuring four stories of residential units above inviting ground-floor retail. Level 3 Construction led Phase II of the project, which included preconstruction budgeting, design coordination, and multi-trade self-performance. Throughout this project, we demonstrated our ability to work across the public and private sectors to deliver a high-impact project to a downtown undergoing a significant revitalization.
- Affordable: South River Village – Oceanside
This 43-unit affordable housing community is exquisitely designed and expertly crafted to look and feel as refined as a market-rate apartment building. From a developer perspective, this project is unique in that it is the City of Oceanside’s first off-site affordable housing community, fulfilling the inclusionary housing requirements for North River Farms, a nearby market-rate development of 395 homes by Lennar.
- Hotel Construction: WoodSpring Suites Corona – Corona
The WoodSpring Suites Corona is a 122-room extended-stay hotel thoughtfully designed for comfort, convenience, and efficiency. Strategically located off the I-15 freeway, the four-story WoodSpring Suites offers spacious guest suites with full kitchens and ample storage, alongside amenities including a welcoming lobby, fitness center, and laundry facility. Delivered on schedule and to exacting brand standards, this project reflects our team’s expertise in hospitality construction – and has already led to a second contact, this time in Santee, California.
- Hotel Renovation: Hotel Santa Barbara – Santa Barbara
We recently completed a phased renovation of the historic Hotel Santa Barbara, a landmark beloved by travelers from around the world. Building on our previous work at the property, we refreshed all 75 guest rooms. We also enhanced the lobby and reception areas, and built out a brand-new, all-day bar – all while preserving the hotel’s timeless character. Carefully staged to respect the guest experience, the renovation reflects our expertise in balancing historic preservation with contemporary hospitality standards.
These projects are just a small sample of our work in recent years and reflect our diverse capabilities: from architectural sophistication in San Diego neighborhoods to major hotel renovations along the coast.
With over 60 years of combined leadership experience, the Level 3 Construction team brings deep expertise across multifamily, mixed-use, hospitality, affordable/workforce, senior living, and student housing projects.
From our award-nominated Point Loma residential community to our mixed-use retail/residential development in the heart of Oceanside, we deliver projects that are constructed well and aesthetically pleasing.
Communication, transparency, responsiveness, and integrity govern our culture. From our field crews to our project leaders, the Level 3 Construction team fosters trust and partnership, project after project.
