Building Code Compliance

The extent to which a building's construction, systems, and use meet applicable local, state, and federal codes — a status that can shift under a building as codes are updated over time.

Definition

Building code compliance refers to the extent to which a building's construction, systems, and use meet applicable local, state, and federal building codes and regulations. Building codes evolve over time, so a structure built decades ago may have been fully compliant when constructed but no longer meet current standards — understanding a property's compliance status, and any grandfathered exceptions, is important due diligence.

Common compliance areas to verify

Compliance areaWhat to check
Fire and life safetySprinkler systems, egress, fire-rated construction
Accessibility (ADA)Compliant access, restrooms, parking
Electrical and mechanicalCurrent code compliance for building systems
StructuralSeismic or wind load standards for the region

What to watch for before committing

Grandfathered vs actively non-compliant conditions

Understand which non-compliant conditions, if any, are legally grandfathered versus requiring correction.

Trigger events for compliance upgrades

Recognize that certain events, like significant renovation or change of use, can trigger requirements to bring older systems up to current code.

Recent inspection and violation history

Request the property's history of code inspections and any outstanding violations.

ADA compliance specifics

Given frequent litigation risk, pay particular attention to Americans with Disabilities Act compliance for parking, access, and restrooms.

Cost responsibility for compliance upgrades

Clarify in your lease who bears responsibility and cost for any needed compliance upgrades, landlord or tenant.

Local building department verification

Consider verifying compliance status directly with the local building department rather than relying solely on landlord representations.

When you need to know this

  • Evaluating older buildings — assessing compliance risk and potential upgrade costs before leasing
  • Planning significant renovations — understanding whether changes trigger broader code compliance requirements
  • Changing a building's use — confirming the new use doesn't require code upgrades not needed under the prior use
  • Due diligence before signing a long-term lease — verifying compliance status to avoid unexpected future obligations

Frequently asked questions

What is building code compliance? +
Building code compliance refers to the extent to which a building's construction, systems, and use meet applicable local, state, and federal building codes and regulations.
Can an old building still be legal even if it doesn't meet current codes? +
Often yes, through grandfathering provisions that allow older, previously compliant conditions to continue, though certain trigger events like major renovation or change of use can require bringing systems up to current standards.
What triggers a requirement to upgrade to current building codes? +
Common triggers include significant renovation, a change of use or occupancy classification, or in some cases, a certain threshold of damage requiring reconstruction — specific triggers vary by jurisdiction.
Who is responsible for building code compliance costs, landlord or tenant? +
This is negotiable and should be specified in the lease, though it often depends on whether the compliance issue predates the tenant's occupancy or arises from the tenant's specific use or improvements.
