How to Research a Building Before Renting

5 minutes of research can save you from a year of hell. Here's exactly what to check.

8 min readUpdated January 2026

Boston's housing stock is old. Really old. Many triple-deckers were built 100+ years ago. That means a beautiful apartment could hide serious problems: rodents, no heat in January, lead paint, or a landlord who ignores repairs. Before you sign anything, research the building.

The Fast Way: Use StreetSmart

We aggregate RentSmart violations, 311 complaints, property assessments, and building data into one search. Takes 30 seconds.

The Complete Building Research Checklist

1. Check RentSmart Violations

Boston's RentSmart program tracks code violations for rental properties. This is crucial data.

What RentSmart Violations Tell You

  • Heat violations

    Failures to maintain required temperatures (68°F day, 64°F night)

  • Pest infestations

    Rodents, cockroaches, bedbugs—serious and hard to eliminate

  • Structural issues

    Roof problems, foundation issues, fire safety

  • Plumbing/electrical

    Hot water issues, electrical hazards

A building with repeated violations is a red flag. Landlords who ignore problems once will ignore them again.

2. Check 311 Complaints

Boston's 311 system lets residents report issues. Complaints near an address tell you what current tenants are dealing with.

311 Complaint Categories

Rodent ActivityPoor ConditionsImproper StorageNeedle PickupGraffitiStreet/Sidewalk

Frequent complaints at an address = ongoing problems landlord isn't fixing.

3. Check MBTA Proximity

Boston's subway (the T) is the oldest in America. Some lines are more reliable than others.

MBTA Line Reality Check

  • RedMost used. Regular delays. Alewife to Braintree/Ashmont.
  • OrangeRecently upgraded. Oak Grove to Forest Hills.
  • BlueReliable. Wonderland to Bowdoin. Good for East Boston.
  • GreenStreet-level = slow. B/C/D/E branches vary. Often delayed.

StreetSmart shows distance to nearest T stop for any address.

4. Check University Proximity

Boston has 35+ colleges and universities. Living near one means more rental options, but also:

Student Zone Effects

  • • Higher turnover and Sept 1st competition
  • • Weekend noise, especially Thurs-Sat
  • • "Allston Christmas" sidewalk furniture in August
  • • Landlords used to dealing with students (good and bad)

5. Consider Winter Readiness

Boston gets 48 inches of snow per year. An old building with bad insulation or failing heat can be miserable.

Winter Checklist

  • • Check for heat violations in building history
  • • Ask about heating type (gas forced air vs. radiators)
  • • Check windows—old windows = drafts
  • • Ask who clears snow from walks/parking
  • • Confirm heat is included OR check utility estimates
