ADUs: The 2025 Zoning Breakthroughs for Homeowners

ADUs: The 2025 Zoning Breakthroughs for Homeowners

Great news for those needing more space! 2025 saw several Greater Boston towns streamline the approval process for Accessory Dwelling Units (ADUs).

What This Means for You

'By-Right' Approvals*: Many towns now allow ADUs without a special permit, provided they meet size and setback requirements.

• Equity Boost: Adding a legal rental unit or guest house can increase your property value by 15-20%.
• Flexibility: Ideal for 'aging in place' or creating a high-end home office away from the main house.

Town Watch

Arlington and Newton have been leaders in these reforms, making it easier than ever to build 'up or out.'
