A beautiful apartment can hide serious problems. Before you sign a lease, take time to research the building and landlord. Here's exactly what to check in San Diego.

Quick Research Checklist

Step 1: Check Building Violations

San Diego Code Enforcement tracks violations for habitability, safety, and building code issues. High violation counts or repeated issues are major red flags.

What to Look For

  • Total violations: More than 5-10 suggests neglect
  • Open violations: Unresolved issues are serious
  • Pest violations: Often indicate building-wide problems
  • Safety violations: Fire safety, structural issues
  • Recurring issues: Same problems year after year

Step 2: Research the Landlord

A landlord with a history of problems at other properties will likely give you problems too.

How to Find Landlord Info

  1. Ask for the landlord/management company name
  2. Search their name + "San Diego" + "complaints" or "reviews"
  3. Check San Diego County Assessor for ownership
  4. Search court records for eviction cases
  5. Look up Better Business Bureau ratings

Step 3: Check 311 Complaints

San Diego's "Get It Done" 311 system tracks complaints about noise, maintenance, and neighborhood issues. High complaint counts can indicate problem buildings or areas.

Step 4: Visit at Different Times

A building can feel very different at night vs. day, or weekday vs. weekend. Visit multiple times to get a complete picture:

  • Evening: Check noise levels, parking availability
  • Weekend: See the neighborhood's vibe
  • Morning: Check for traffic, parking

Step 5: Talk to Current Tenants

If possible, chat with people who already live there. Ask about:

  • How responsive is the landlord/management?
  • Any pest problems?
  • Noise issues?
  • How long do repairs take?
  • Any issues with neighbors?
  • What's the parking situation really like?

Red Flags to Watch For

  • 🚩 Landlord refuses to show violation history
  • 🚩 Many recent eviction filings
  • 🚩 Numerous negative reviews online
  • 🚩 Building looks poorly maintained
  • 🚩 Current tenants warn you away
  • 🚩 Landlord pressures you to sign quickly
