Morning Chronicle - Wu Administration Proposes Reforms to Boston’s Inclusionary Zoning Rules

Boston Mayor Michelle Wu’s administration unveiled a comprehensive set of proposed modifications to the city’s Inclusionary Development Policy (IDP) and commercial linkage fees on Monday, aiming to alleviate financial pressures that have stalled numerous housing and commercial projects. The reforms seek to provide developers with greater flexibility in meeting affordability mandates while attempting to balance market viability with the city’s commitment to preserving low-income housing stock.

The proposed changes address four specific areas of the Inclusionary Zoning program, which requires new developments to include affordable units or pay fees into the city’s housing trust. First, developers who opt to make payments in lieu of constructing on-site affordable units would be permitted to spread those payments over seven annual installments, an extension from the current two-year requirement. Second, the payment-in-lieu fee for condominium projects would be reduced from 75 percent to 50 percent of the difference between a unit’s market value and its income-restricted value. This adjustment restores the fee structure to levels seen under the city’s previous IDP.

Third, the administration proposes raising the threshold for triggering Inclusionary Zoning requirements from seven units to ten units for a two-year period. Under this temporary exemption, residential projects containing seven, eight, or nine homes would be relieved of the requirement. Finally, the city plans to eliminate the rule mandating that off-site affordable units be located within a half-mile radius of the market-rate development. Instead, housing and planning officials will collaborate with developers and neighborhood stakeholders to identify appropriate locations within Boston.

These adjustments are particularly significant for smaller residential projects in neighborhoods such as Dorchester and Mattapan, where developments comprising fewer than ten apartments or condominiums are common. Kairos Shen, Boston’s chief of planning, noted that the city historically averaged approximately 14 projects annually in the seven-to-nine-unit category. However, activity in this segment has declined sharply, with only one such project recorded in 2026.

"We would like to actually make sure that this band, even though it’s only approximately 14 projects, that those can go forward without the burden of providing the inclusionary unit at that scale," Shen said. He emphasized that while the temporary exemption removes a regulatory hurdle, it does not guarantee financial feasibility for all smaller projects, as construction costs, land prices, and building code requirements remain critical factors.

The previous affordability policy utilized a 10-unit threshold, which was lowered to seven units during the 2023 reforms. The administration’s decision to maintain the core 17 percent affordable housing requirement, along with an additional 3 percent for voucher-supported households, reflects a deliberate choice to preserve affordability mandates despite developer arguments that these mandates contribute to financial difficulties in new construction.

During a briefing on Monday, officials addressed why the city is modifying payment schedules and thresholds rather than reducing the overall percentage of required affordable units. Sheila Dillon, Boston’s chief of housing, stated that the administration is attempting to balance two competing priorities: encouraging market-rate housing production and ensuring that lower-income residents can continue to find homes in Boston.

"We want to work with developers to ensure that their market-rate projects can move forward, and we also want to make sure that Boston is a home for everyone," Dillon said. She explained that extending the payment schedule preserves the total amount owed by rental housing developers while providing more time to meet obligations. For condominium developers, however, the city will collect less per unit when the payment-in-lieu option is exercised. Dillon argued that the lower fees would ultimately benefit the city by enabling more projects to advance in a market where few condominium developments are currently moving forward.

The proposals also address the city’s commercial linkage program, which requires qualifying commercial and institutional developments to contribute funding for affordable housing and job training. Originally adopted in 1983, the program was expanded in recent years to cover developments of at least 50,000 square feet, down from a previous threshold of 100,000 square feet. Under current rules, commercial linkage fees are adjusted annually for inflation. Without intervention, rates were scheduled to rise automatically by approximately 4.09 percent at the start of 2027.

Shen noted that freezing these fees would not single-handedly make unworkable projects financially viable but would prevent adding another burden to developers who have expressed interest in restarting stalled commercial projects in downtown Boston. The job-training portion of commercial linkage payments will continue to be collected in two installments. Since 1983, the city’s Neighborhood Housing Trust has collected more than $280 million through these payments. Between 2015 and 2025, the Neighborhood Jobs Trust collected approximately $30 million to support organizations serving over 10,000 low- and moderate-income residents.

Kathy Brown, executive director of the Boston Tenant Coalition and co-coordinator of the Coalition for a Truly Affordable Boston, issued a statement supporting the changes. "The changes being made are preferred over rolling back IZ from 20 percent to 13 percent of units built," Brown said, indicating that tenant advocates view the adjustments as a preferable alternative to significant reductions in affordability requirements.

The proposed Inclusionary Zoning changes are scheduled to be reviewed by the Boston Planning and Development Agency board on Thursday, November 12. Following this review, the changes will be subject to City Council oversight. Under the process outlined by officials, the council has 60 days to reject the modifications by a two-thirds vote before they can proceed to the Zoning Commission. The commercial linkage fee adjustments require approval by the Zoning Commission before the scheduled increases take effect on January 1.
