How a narrow three-story mixed-use project signals the next chapter for San Francisco’s Garden District.
San Bruno Avenue is the spine of the Portola. For over a century, this corridor has served as a transition zone between the city’s dense urban core and the rolling hills of the southeast sector. Today, a single-story home at 2785 San Bruno Avenue, likely built in the early 1920s, stands as a quiet reminder of the neighborhood’s residential past. But the city is changing, and the revised plans for this narrow lot represent a significant milestone in San Francisco’s push for "missing middle" housing (SF YIMBY) [2]. By replacing one aging structure with three residential units and two commercial spaces, the project team at GF Construction Co. and RKD Consulting is demonstrating how small-scale infill can breathe new life into commercial transit districts.
This isn't just about adding a few apartments | it is a masterclass in navigating the modern San Francisco permitting labyrinth. Leveraging the protections of the Housing Crisis Act, known as SB 330, the developers have successfully locked in zoning and fees to ensure the project remains viable despite fluctuating material costs and interest rates (SF Planning) [6]. For property owners and contractors, the 2785 San Bruno project serves as a blueprint for high-density, low-rise development that respects local vernacular while hitting the targets of the city’s ambitious Housing Element. As we walk through the details of this 3,560-square-foot proposal, we see a neighborhood evolving from a historic "Garden District" into a modern, transit-oriented community.

The Anatomy of an Infill Project
The proposed structure at 2785 San Bruno Avenue is a lean, efficient exercise in urban design. Standing 36 feet tall, the building will occupy a lot currently bounded by Bacon Street and Wayland Street, positioned perfectly for visibility along the San Bruno Avenue retail strip (SF YIMBY) [2]. The program includes 2,840 square feet of residential space and 730 square feet dedicated to two ground-floor commercial storefronts. This mix is intentional. By providing two smaller retail spaces rather than one large one, the project increases the odds of attracting local, independent businesses that define the Portola’s character.
Residential unit sizes will vary to cater to different household needs, featuring two two-bedroom units and one expansive three-bedroom residence. In a city where large families are often squeezed out by a surplus of studios, the inclusion of a three-bedroom unit is a notable win for neighborhood stability. Furthermore, the decision to exclude vehicle parking in favor of three bicycle spaces reflects the project’s identity as a transit-oriented development (SFMTA) [7]. This move not only reduces construction costs | which are estimated at $1.05 million for the build alone | but also aligns with San Francisco’s long-term climate and transit goals.
Portola’s Agricultural Legacy and the Garden District
To understand why this development matters, one must understand the soil it sits on. The Portola was historically known as "San Francisco’s Garden," a place where Italian, Maltese, and Jewish immigrants built dozens of greenhouses that once supplied the majority of the city’s cut flowers and produce (Foundsf) [1]. From the early 1900s through the mid-20th century, the valley was a sea of glass and redwood structures. This heritage was formally recognized in 2016 when the neighborhood was designated as San Francisco’s Garden District (Portola Neighborhood Association) [3].
The transition from greenhouses to homes began in earnest after World War II, but the Portola has retained a unique, low-slung residential character that many residents are keen to protect. Small-scale infill projects like 2785 San Bruno are the modern equivalent of the neighborhood's historic evolution. They provide a way to increase density without the jarring impact of high-rise towers. By utilizing "Hardie wood-look panels" and stucco, the new building pays homage to the natural textures associated with the Garden District while offering the fire resistance and durability required by modern building codes (James Hardie) [15].
The Economics of Small-Scale Mixed-Use
Building at this scale is notoriously difficult in San Francisco. While massive 500-unit towers have the economy of scale to absorb high entitlement costs, a three-unit project like 2785 San Bruno operates on thin margins. The estimated construction cost of $1.05 million represents only a portion of the total investment (SF YIMBY) [2]. When you factor in land acquisition, soft costs, and the current 2026 interest rate environment, the financial "pencil-out" requires surgical precision.
This is where the expertise of firms like Atlas Premier Services & Consultants becomes invaluable. Managing the gap between a $300-per-square-foot construction estimate and the final delivery price requires a deep understanding of local labor markets and material lead times (ENR) [14]. For GF Construction Co., the success of this project hinges on the efficiency of the "narrow infill" model. By keeping the footprint compact and the systems centralized, the team can deliver high-quality housing at a price point that remains competitive within the southeast sector’s rental and retail markets.
Navigating the San Francisco Permitting Labyrinth
The permitting journey for 2785 San Bruno has been a long one. Records show that concepts for this site date back over a decade, with a 2014 proposal for a four-story building that ultimately never moved forward (SF YIMBY) [3]. The current success of the revised plans can be attributed to a more grounded approach to density and the tactical use of current state housing laws. San Francisco’s Planning Department has historically been a bottleneck for small developers, but new mandates are forcing a change in pace.
Case No. 2025-007500CUA represents the formal Conditional Use Authorization required for the project (SF Planning) [5]. Because the site is located in the NCT-San Bruno Avenue Neighborhood Commercial Transit District, the ground-floor retail is a requirement, but the residential density above is what makes the project work financially. For owners of similar lots along San Bruno Avenue, the key lesson is early engagement with a design team that understands the specific nuances of the NCT zoning, which prioritizes pedestrian-active storefronts and housing proximity to transit.
SB 330 and the Power of Streamlining
Perhaps the most critical tool in the 2785 San Bruno toolkit is Senate Bill 330, also known as the Housing Crisis Act of 2019. This law was designed to stop "death by a thousand cuts" during the entitlement process. By filing a preliminary application under SB 330, a developer can "vest" the rules, regulations, and fees in place at the time of filing (California Gov Code) [4]. This means that even if San Francisco were to pass new, more restrictive zoning or higher impact fees tomorrow, this project would be protected.
Furthermore, SB 330 limits the number of public hearings to five, preventing projects from being stuck in a perpetual loop of community meetings and appeals (Terner Center) [16]. For a project of this size, where every month of delay adds thousands in carrying costs, this streamlining is the difference between a project that gets built and one that remains a set of blueprints on a shelf. The revised plans for 2785 San Bruno are a direct beneficiary of these state-level protections, proving that even small infill projects can wield significant legal leverage.
Architectural Vernacular: Modern Bays and Hardie Panels
Design firm RKD Consulting has chosen to lean into "San Francisco vernacular" rather than fighting against it. The most prominent features of the new facade are the two two-story bay windows facing San Bruno Avenue (SF YIMBY) [2]. Bay windows are more than just a stylistic choice | they are a functional necessity for narrow lots, allowing for 180-degree light and views in rooms that might otherwise feel cramped.
The material palette is equally strategic. By combining traditional stucco with modern Hardie wood-look panels, the building achieves a contemporary aesthetic that doesn't feel cold or industrial. These materials are also chosen for their longevity in San Francisco’s foggy, salt-rich air. For general contractors, the use of fiber-cement siding (Hardie) offers a predictable installation process and lower long-term maintenance costs for the building owner, making it a favorite for modern infill construction (James Hardie) [15].
Transit-Oriented Development in the Southeast Sector
The Portola is often overlooked in discussions about San Francisco transit, but the San Bruno Avenue corridor is a vital artery. The site at 2785 San Bruno is served by multiple Muni lines, including the 8 Bayshore and the 9 San Bruno, providing direct links to the Market Street corridor and the Caltrain stations (SFMTA) [7]. This connectivity is why the project was able to move forward with zero on-site vehicle parking.
This "car-free" approach is becoming the standard for San Bruno Avenue. The San Bruno Avenue Multimodal Improvement Project has already introduced transit-only lanes and pedestrian safety upgrades to the area, making it increasingly viable for residents to live without the burden of a personal vehicle (SFMTA) [7]. For future tenants of the 2785 San Bruno apartments, the trade-off is clear: they gain high-quality, modern living space in a walkable neighborhood in exchange for a slightly longer commute on high-frequency transit.
The Future of San Bruno Avenue Commercial Transit
As we look toward the completion of this project, it is clear that 2785 San Bruno is part of a larger trend. The Portola is no longer a "hidden gem" | it is an active participant in San Francisco’s housing recovery. Small-scale developers are looking at the Garden District as a place where they can still find lots that are ripe for redevelopment. The success of this project will likely trigger a wave of similar applications for single-story retail or aging homes along the avenue.
The goal for the city should be to ensure that this growth doesn't erase the unique character of the Portola. By maintaining the requirement for ground-floor retail and encouraging architectural diversity, San Francisco can allow the neighborhood to grow while staying true to its roots as a place of industry and community. The evolution of 2785 San Bruno Avenue is a small but vital step toward a more resilient, dense, and vibrant San Francisco.

Case Example: The Resilience of the Small-Scale Developer
In 2014, the site at 2785 San Bruno Avenue was at a crossroads. A developer had proposed a four-story building, but the project stalled due to the complexities of San Francisco’s discretionary review process and a lack of clear streamlining tools (SF YIMBY) [3]. The project sat idle for nearly a decade, a victim of the very "housing gap" it was meant to fill.
Fast forward to 2026, and the landscape has changed. GF Construction Co. took a different approach. Instead of pushing for maximum height, they aligned their goals with the NCT zoning and the protective umbrella of SB 330. By scaling the project to three stories and including family-sized units, they reduced potential friction with the Planning Commission and neighbors. This "measured density" approach has allowed the project to move from pre-application to revised plans in under a year, a pace that was unheard of in the 2010s. This case demonstrates that success in San Francisco real estate often comes down to knowing which tools | like SB 330 | to use and when to use them.
What Smart Critics Argue
- Loss of Historical Fabric: Critics argue that demolishing 100-year-old homes, even those without a formal landmark status, slowly erodes the architectural soul of neighborhoods like the Portola (Foundsf) [1].
- Parking Congestion: Opponents of "zero-parking" developments claim that transit-oriented projects merely shift the parking burden to already crowded side streets like Bacon and Wayland (SFMTA) [7].
- Commercial Viability: Some skeptics worry that 730 square feet divided into two retail spaces is too small for modern businesses, potentially leading to high turnover or vacant storefronts (SF Business Times) [14].
- Shading Concerns: Adjacent property owners often raise concerns about the 36-foot height blocking sunlight to existing backyards, particularly in a district defined by its "Garden" history (SF Planning) [5].

FAQ
Why is this project only three stories instead of four?
The current design balances financial feasibility with neighborhood scale and NCT zoning requirements, opting for a 36-foot height that fits within standard residential height limits (SF YIMBY) [2].
What does SB 330 actually do for this project?
SB 330 "vests" the project, meaning the rules and fees in place when the preliminary application was filed cannot be changed by the city later in the process (California Gov Code) [4].
Will the retail spaces be for a single tenant?
The revised plans show 730 square feet divided into two separate commercial spaces, allowing for two independent businesses (SF YIMBY) [2].
How do I find out about the Planning Commission hearing?
Public notices are posted on the SF Planning website under Case No. 2025-007500CUA (SF Planning) [5].
Is there any parking for residents?
No car parking is included. The project provides three bicycle parking spaces to encourage transit use (SFMTA) [7].
