City Realty's $41M Route 9 office park acquisition could reshape Chestnut Hill with 783 apartments—if Town Meeting approves rezoning in May 2026.
City Realty Group’s $41 million acquisition of the largely vacant Chestnut Hill Office Park in May 2024 has set the stage for Brookline’s most significant Route 9 transformation in decades. The developer proposes converting four mid-1960s office buildings into a mixed-use complex with 783 multifamily units.
Tax Revenue or Traffic? The Fiscal Trade-Off
Brookline operates under Proposition 2½, which caps annual property tax levy growth at 2.5% plus new growth. According to developer projections, the redevelopment could generate approximately $9 million annually in new local property taxes, compared to roughly $1 million currently. Commercial properties in Brookline carry tax rates approximately 68% higher than residential rates, making mixed-use development particularly attractive to town leadership. Yet the project’s residential component—783 units, of which 25% must be affordable under Chapter 40B—will add school-age children and municipal service demands.
Homeowners in Hammond, Heath, and Dunster neighborhoods may experience valuation shifts tied to density, traffic, and retail amenities. Properties within 500 feet of the site should track design guidelines and Town Meeting updates before listing or purchasing.
Buyers seeking entry-level or family housing should note that the 783-unit pipeline could ease pressure on Brookline’s median home price of $1.1 million, but only 196 units will be deed-restricted as affordable.
Commercial landlords and retail tenants on Route 9 may face lease restructuring or displacement. Existing tenants at 1330 Boylston should clarify relocation rights and lease status now.
Developers eyeing similar office-to-residential conversions should watch City Realty’s dual-pathway strategy, which leverages state housing law to pressure local zoning and could set a template for future projects.
Families considering Brookline schools should anticipate enrollment pressure if the project adds 200+ school-age children, potentially affecting class sizes and redistricting decisions.
Investors in Chestnut Hill multifamily properties may face increased competition from 783 new rental units entering the market between 2027 and 2029, which could pressure rents and cap rates.
What Buyers and Renters Should Watch
City Realty has filed Project Eligibility Letters with MassHousing under Chapter 40B, creating a dual-pathway strategy: secure favorable rezoning at the Spring 2026 Annual Town Meeting beginning May 26, or proceed with a residential-only override that bypasses local zoning. Brookline’s Subsidized Housing Inventory was certified at 10.76% as of November 2025, just above the 10% threshold that triggers 40B protections. Renters and buyers earning $80,000 to $130,000 should investigate Brookline CDC and Housing Advisory Board pipelines to understand which units will carry long-term affordability covenants.
