Somerville HOA Rules: Architectural Review Rules (2026)

In Somerville condos, modifications to unit exteriors, windows, doors, decks, signage, and common areas are typically subject to architectural review by the Board of Trustees under authority granted by the Master Deed and Bylaws. MGL c.183A treats exterior walls, roofs, windows, and most visible elements as common or limited common areas, meaning individual owners cannot unilaterally change them. Owners typically must submit written applications describing the proposed change, materials, colors, and contractor information. Boards may require compliance with Somerville's Historic District or Local Historic Overlay rules where applicable, as many Somerville buildings fall within designated historic areas requiring review by the Somerville Historic Preservation Commission. Interior-only changes that do not affect structural elements, plumbing stacks, or common utilities are generally permitted without board review but may still need Somerville building permits. Unapproved exterior modifications can be ordered reversed at the owner's expense.
