This week in the data
This is a baseline intelligence brief, as no delta updates have been provided for this period. Our analysis for Cambridge, MA covers 12,938 parcels with a total assessed value of over $73.8 billion. The city holds a substantial 106.3 million square feet of existing building area, alongside a remarkable 60.9 million square feet of 'unused GFA' (Gross Floor Area). This represents potential developable space on underbuilt parcels, which number 789 across the city. These figures underscore the significant redevelopment potential embedded within Cambridge's existing property fabric.
Surface parking and low-coverage sites
Cambridge's land use profile reveals substantial opportunities for redevelopment on sites currently underutilized, often appearing as surface parking, garages, or large yards. These parcels are characterized by a low existing FAR (Floor Area Ratio) relative to their allowable zoning, suggesting significant capacity for new construction. The total unused GFA across the city stands at 60,936,076.3 square feet. This potential is not evenly distributed, with certain zip codes showing disproportionately high figures due to large institutional or industrial holdings.
For instance, the 02138 zip code (Harvard Square / West Cambridge) holds 15,980,741 square feet of unused GFA, with candidate sites like 2 Oxford St (lot 1,268,902.8 sq ft, built 60,640 sq ft, unused GFA 3,746,068.4 sq ft, total value $999,999,999) and 11-19 Oxford St (lot 1,210,532.4 sq ft, built 42,633 sq ft, unused GFA 3,588,964.2 sq ft, total value $1,284,425,700) demonstrating immense latent value. Similarly, 02140 (North Cambridge / Porter) presents 12,876,547 sq ft of unused GFA, highlighted by 250 Fresh Pond Pkwy (lot 7,251,433.2 sq ft, built 0 sq ft, unused GFA 1,812,858.3 sq ft, total value $210,509,100).
Kendall Square (02142) shows 13,157,843 sq ft of unused GFA, often within expansive institutional or commercial campuses. 60 Vassar St stands out with 5,489,179.19 sq ft of unused GFA on a 1,848,686.4 sq ft lot. These large parcels, many of which house substantial but relatively low-coverage structures, represent prime targets for strategic infill or complete redevelopment projects. The data suggests that much of this potential GFA resides in zones like C-3 (commercial-3) and OS (Open Space) where large lots are common, or within institutional campuses that may have special zoning or PUD designations that allow for significant future build-out.
Zip-code investment read
Comparing zip codes reveals distinct investment profiles for maximizing undeveloped floor area:
- 02142 (Kendall Square): While having only 134 parcels, this zip code boasts the highest median total value ($64,363,300) and median land value per sq ft ($473.68). With 13,157,843 sq ft of unused GFA and 35 underbuilt parcels, it offers high-value, high-potential projects, albeit with potentially complex ownership (e.g., MIT, large corporations). The presence of MXD and PUD-3 zones indicates planning for intense development.
- 02138 (Harvard Square / West Cambridge): This area shows the highest total unused GFA at 15,980,741 sq ft across 119 underbuilt parcels. With a median total value of $2,960,500 and median land value per sq ft of $249.20, it represents a robust market for significant institutional or mixed-use expansion, particularly around C-3 zoned properties.
- 02140 (North Cambridge / Porter): Offering 12,876,547 sq ft of unused GFA on 182 underbuilt parcels, this zip code provides opportunities at a lower median land value per sq ft ($149.71) compared to more central areas. Large OS (Open Space) zoned parcels, like the two 250 Fresh Pond Pkwy listings, indicate potential for re-designation or public-private partnerships.
- 02139 (Central Square / Mid-Cambridge): With 11,179,732 sq ft of unused GFA on 276 underbuilt parcels, this area has a median land value per sq ft of $269.32. The prevalence of C-1 and C zones suggests commercial or mixed-use infill, often on smaller but well-located lots.
Risk assessment varies; Kendall Square offers high reward but also high cost and potentially lengthy approval processes for major projects. North Cambridge might present lower entry costs but could involve more community engagement for significant rezonings. Harvard Square, while offering immense potential GFA, is dominated by institutional ownership that moves on its own development schedule.
What to do next
1. Prioritize Large, Low-Coverage Parcels: Focus screening on parcels with `lotSqFt` over 100,000 sq ft and `builtSqFt` less than 10% of `lotSqFt`, cross-referencing with high `unusedGfaSqFt` in zip codes 02138, 02140, and 02142. These are the classic 'surface parking' opportunities. 2. Investigate Institutional Campuses: Target large parcels within C-3, OS, and MXD zones, especially those with high `totalValue` and `unusedGfaSqFt`, indicating major institutional or corporate holdings ripe for long-term strategic partnership or campus master plan engagement. 3. Analyze Underbuilt Commercial/Industrial Zones: Screen for `IA`, `IB`, `C-1`, and `C-2` zoned parcels within 02141 (East Cambridge) and 02139 (Central Square) that show significant `unusedGfaSqFt`, as these might be smaller, more accessible infill opportunities for commercial or mixed-use redevelopment.
