How Do I Know If My Contractor Is Building to Code?

When hiring a contractor, most homeowners assume the work will meet building code requirements.

But how can someone tell whether a project is actually being built to code — especially if they’re not in the construction industry?

For homeowners in Central Pennsylvania, understanding a few key indicators can provide clarity and confidence.

What Does “Built to Code” Actually Mean?

Building to code means the project complies with:

• The International Residential Code (IRC)

• Pennsylvania Uniform Construction Code (UCC)

• Local municipal requirements

• Required inspections and approvals

Code compliance is not about preference or opinion. It is about meeting minimum safety and structural standards established to protect homeowners.

1. Is a Permit Being Pulled?

One of the clearest indicators of code compliance is whether the contractor is obtaining the required permits.

In Central PA, projects that typically require permits include:

• Decks over 30 inches in height

• Structural modifications

• Additions

• Plumbing changes

• Electrical updates

If a contractor suggests skipping permits to “save time” or “save money,” that is a red flag.

Permits trigger inspections, and inspections verify compliance.

2. Are Inspections Scheduled and Passed?

Building to code involves more than pulling a permit.

It requires:

• Footer inspections (for decks and additions)

• Framing inspections

• Plumbing inspections

• Final inspections

Homeowners can ask:

• Has the inspection been scheduled?

• Was it approved?

A reputable contractor should have no hesitation discussing inspection status.

3. Are Proper Systems Being Used (Not Just Surface Materials)?

Code compliance often involves what’s behind the finished surface.

For example:

In showers:

• Waterproofing membranes must be installed properly.

• Plumbing connections must meet code.

• Drain integration must be correct.

On decks:

• Footings must meet frost depth requirements (42 inches locally).

• Joist spans must meet load calculations.

• Guardrails must meet height and load standards.

A project can look good visually and still fail inspection if structural or system requirements are ignored.

4. Can the Contractor Explain Their Process Clearly?

A contractor building to code should be able to explain:

• How the structure is supported

• What waterproofing system is being used

• How plumbing is vented

• Why certain framing sizes were selected

• How inspections are handled

Clear explanations are often a sign of competence and compliance.

Vague answers are not.

5. Is There Documentation?

Code-compliant projects typically generate:

• Permit paperwork

• Inspection records

• Approved plans (when required)

Homeowners are entitled to copies of final approvals. These documents are especially important during resale.

6. Is the Work Aligned with Local Requirements?

Building code can vary slightly by municipality.

For example, in parts of Central Pennsylvania:

• Frost depth is 42 inches.

• Decks over certain heights require specific guardrail standards.

• Zoning approval may be required before construction begins.

A contractor familiar with local enforcement requirements is less likely to encounter inspection failures.

Why Code Compliance Matters

Building code is not optional bureaucracy.

It protects:

• Structural integrity

• Fire safety

• Moisture management

• Plumbing performance

• Electrical safety

Ignoring code may reduce upfront cost, but it increases long-term risk.

Final Thoughts

Homeowners do not need to know every code detail to ensure compliance.

They simply need to ask:

• Is a permit being pulled?

• Are inspections scheduled and passed?

• Can the process be clearly explained?

• Is documentation available?

A contractor building to code should welcome those questions.

Compliance is not a marketing claim. It is a measurable standard.
