How do I negotiate lower rent on an apartment?

Use StreetSmart to find building violations and landlord history, then leverage that data in rent negotiations. Buildings with open violations, pest issues, or maintenance problems give you leverage to negotiate 10-20% lower rent. Our free tool shows you exactly what issues exist so you can ask for fair pricing.

Can building violations help me lower my rent?

Yes! Open violations are powerful negotiation leverage. If a building has unresolved code violations, pest complaints, or safety issues, you can use this official data to negotiate lower rent or ask for repairs before signing. Many renters save $100-500/month using this approach.

Is StreetSmart free to use?

Yes, StreetSmart is 100% free with no credit card or sign-up required. You can instantly view building violations, landlord ratings, and use our rent negotiation tools for millions of apartments across 10 major US cities.

How can I tell if my rent is too high?

Search your building on StreetSmart to see violation history, landlord ratings, and compare to similar buildings. If your building has significant issues but charges premium rent, you have grounds to negotiate. Our tools help you make data-backed requests for fair pricing.

Patterns & trends

Core Principles

Time Decay

5yr

decay window

Old resolved issues fade over time. 6mo=100%, 1yr=85%, 2yr=60%, 3yr=35%, 5yr=15%, 5yr+=3%. Open violations always count at full weight.

Open vs Closed

5-12×

open weight

Open violations are 5-12× more impactful than closed ones. A building that fixes issues quickly scores better.

Per-Unit Normalization

units

10 violations in a 100-unit building is better than 10 in a 5-unit building. Large buildings are judged fairly.

Building Fingerprint

±0.5

unique offset

Each building gets a unique ±0.5 adjustment based on its PIN hash. This ensures no two buildings have the exact same score—creating true rankings.

Score Compression

99.5

maximum

Scores above 90 are compressed (90-105 → 90-99.5) to create spread at the top. Top buildings differentiate naturally.

Catastrophic Caps

cap at 300+ viols

Buildings with 300+ violations capped at 30-40. 200+ capped at 40. 100+ capped at 55. Terrible buildings can't hide.

Chicago-Specific Factors

What makes Chicago scoring unique

Winter Heat Focus

Chicago winters are brutal. Heat violations are weighted heavily because a building that fails to provide adequate heat in January is a serious concern. Multiple winter heating failures trigger extra penalties.

77 Community Areas

Chicago is organized into 77 community areas, each with distinct characteristics. Rankings are calculated both citywide and within each community area for fair comparison.

CTA Proximity

We track proximity to CTA L train stations. Buildings near transit score a location bonus—getting around Chicago without a car is a major quality-of-life factor.

Urban Pest Context

Chicago has proactive rodent baiting programs tracked via 311. We analyze both building violations AND neighborhood-level pest complaints to give a complete picture.

Note on Rent Control: Illinois does not have rent control (Rent Control Preemption Act of 1997). Unlike NYC, Chicago buildings don't have rent-stabilized units. However, the RLTO (Residential Landlord and Tenant Ordinance) provides strong tenant protections for buildings with 6+ units.
