Condo Market in Boston, MA
Median price, HOA fees, insurance, energy mandates, and hidden costs for Boston condos in 2026.
Boston Condo Market Overview
Boston's Building Emissions Reduction and Disclosure Ordinance (BERDO 2.0) requires large buildings to achieve net-zero emissions by 2050, with interim targets starting in 2025. Boston's aging condo stock — much of it in converted brownstones and pre-war buildings — faces enormous retrofit costs. The city's tight supply keeps prices elevated, but true carrying costs including HOA fees, insurance, and now energy compliance make the rent-vs-buy math increasingly favor renting.
Energy Mandate Status
Deadline: 2025 (reporting), 2030 (compliance)
Condo buildings in Boston must comply with BERDO 2.0 requirements. Non-compliant buildings face financial penalties that are passed through to unit owners as special assessments or HOA fee increases. Compliance typically requires HVAC upgrades, insulation improvements, window replacement, and potential electrification of building systems.

The average HOA fee for a condo in Boston is approximately $575 per month as of 2026. However, HOA fees increase an average of 6% per year, meaning today's $575/month fee will likely exceed $1029/month within 10 years. The Condo Trap breaks down exactly where this money goes and why most of it never builds equity.
When you account for all carrying costs — HOA fees averaging $575/mo, insurance at $2,100/yr, special assessments averaging $15,000, and BERDO 2.0 compliance costs — the true monthly cost of owning a mortgage-free condo in Boston can exceed $1000/month. Year-over-year prices have changed 2.1%.
Boston condos are subject to BERDO 2.0 with compliance deadlines in 2025 (reporting), 2030 (compliance). These mandates can require building-wide upgrades to HVAC, insulation, and windows — costs that are passed to unit owners through special assessments or HOA fee increases. The Condo Trap covers the financial impact of energy mandates in detail.
