Waltham, MAInc. 1634

Waltham is a city with deep industrial roots — the Waltham Watch Company pioneered the American system of interchangeable parts manufacturing here in the 1850s, and the city's identity as a center of innovation has continued through the 20th and 21st centuries. Today Waltham sits at the heart of the Route 128 technology corridor, with Brandeis University, Bentley University, and major corporate campuses contributing to a diverse economic base.

The housing stock reflects Waltham's complexity: dense multi-family neighborhoods near Moody Street and the downtown, established single-family areas in the south and west sides, and the commercial and institutional properties along Route 128 and the river. For property professionals, Waltham offers an unusually wide range of property types and values for a city its size — from modest multi-family buildings to high-end residential and significant commercial properties — all within a compact geography.

Most of Waltham (99%) is on municipal sewer. Electric service is provided by NSTAR ELECTRIC COMPANY. 2,133 properties have identified commercial activity — restaurants, retail, professional offices, and services that give Waltham its character.

Environmental note: Waltham has an average EPA lead paint indicator at the 51th percentile nationally, consistent with 1,116 properties built before 1900 when lead paint was standard. 5,451 properties exceed at least one EPA environmental justice threshold — a factor in lending compliance and environmental due diligence.

What Waltham Property Intelligence Means for Professionals
