In a recent government meeting, discussions centered around the proposed expansion of the Corona Heights Special Use District (SUD) and its implications for housing density and lot sizes in the area. The SUD was initially established to address the challenges posed by substandard lots in the hilly neighborhood, where lot sizes vary significantly. Officials noted that while many lots in flatter areas conform to standard sizes, Corona Heights features a mix of larger lots, some exceeding the typical 2,500 square feet threshold.

The meeting highlighted the potential for increased housing density, with officials clarifying that the proposed ordinance would not limit new developments to just two units per lot. Instead, it could allow for multi-unit buildings in various zoning districts, including those with higher density allowances. The discussion also touched on the average unit sizes across neighborhoods, revealing that areas like Noe Valley and Twin Peaks have average home sizes around 1,450 square feet, while denser neighborhoods like Castro Upper Market average about 1,342 square feet.

Commissioners expressed concerns about the impact of large homes on neighborhood dynamics and affordability. One commissioner emphasized the need for reasonable home sizes to prevent the displacement of families, noting that the current housing market is increasingly inaccessible to middle-class residents. The proposed maximum size of 3,000 square feet for new homes was deemed substantial, with some commissioners advocating for flexibility in the recommendations to accommodate diverse housing needs.

The meeting also addressed the complexities of accessory dwelling units (ADUs) and how they are calculated in relation to overall building size. Officials indicated that the intent behind limiting home sizes is to incentivize the construction of smaller, more affordable units, thereby increasing overall housing availability.

Ultimately, the commission voted on a motion to approve the recommendations with modifications, passing it with a narrow margin of 4 to 3. The discussions underscored the ongoing challenges of balancing housing density, affordability, and neighborhood integrity in San Francisco's evolving urban landscape. The next agenda item will focus on proposed amendments regarding laboratory uses in the urban mixed-use zoning district.
