## Frequently asked questions

**How many approved Title 5 inspectors are in Middlesex County?**

Title 5 Roster lists 149 MassDEP-approved System Inspectors (143 listings) with an address in 45 towns in Middlesex County, from NEIWPCC's 10/2/2026 list. Inspectors often work across a region, so ask each one about availability.

**Do I need a Title 5 inspection to sell a house in Middlesex County?**

Title 5 generally requires an inspection within 2 years before a sale (3 years with annual pumping), and the report goes to the local Board of Health ([Mass.gov](https://www.mass.gov/guides/buying-or-selling-property-with-a-septic-system)). Local bylaws can add rules, so check with the town's Board of Health.

**Which Middlesex County towns have the most approved inspectors?**

Westford (13 listings); Hopkinton (9 listings); Littleton (9 listings). Counts are listings with an address in each town on NEIWPCC's list.

**How much does a Title 5 inspection cost in Middlesex County?**

We don't have county-specific price data. Published 2026 estimates put the inspection alone at $300–$900, and pumping is often extra. MassDEP doesn't regulate fees, so get written prices from two or three approved inspectors. See [sources and what changes the price](https://title5roster.com/title-5-inspection-cost/).
