As a primary service to a growing number of Municipal clients, Yerkes Associates performs a broad variety of inspections and plan reviews to assure compliance with the International Code Council (ICC) and our Municipal client’s Codes. All of our Code Officials and Plan Examiners hold the required State certifications in the construction discipline for which they are responsible. These include:

  • Building
  • Electrical
  • Energy
  • Plumbing
  • Mechanical

These certifications are for both commercial and residential construction projects. Our inspectors also conduct inspections to assure compliance with:

  • Accessibility standards
  • Fire Suppression Systems
  • Fire Alarm requirements

Yerkes Municipal Department employs all fulltime inspectors. They serve as Code Officials, Plan Examiners, Zoning Officers, Land Development Inspectors and Plan Reviewers. The most important goal of the Department is to make sure home and business owners know that their buildings meet municipal codes as well as the requirements of the Uniform Construction Code and provide a safe place to live and work.


Yerkes Associates is a third party agency, certified in Pennsylvania by the Department of Labor and Industry (L&I), to enforce the Pennsylvania Construction Code Act 45 of 1999 (UCC). Our inspectors jointly carry the individual certifications required for enforcement of commercial, as well as, residential codes.

Yerkes inspectors not only enforce building codes, we believe that a good relationship with contractors is necessary to ensure safety and quality in the built environment. To this end, we are prepared to seek solutions rather than problems and work cooperatively with the municipality and builder to ensure compliance with the intent of the adopted codes.

We take pride in enforcing the codes “as the boos are written” but never based upon personal experience or opinion. We do our best to explain not only what the code says but why it says it. In this way we gain compliance rather than confrontation.


Yerkes Associates enforces Zoning Codes for our clients in a manner consistent with the Pennsylvania Municipalities Planning Code. Two members of our staff recently completed classes and achieved the status of Master Planners in Chester County of which zoning was a major component of the coursework.

Our zoning officers review every application, complaint and enforcement in detail, providing a carefully considered opinion that “enforces the literal intent” of the code. We always strive in all of our client municipalities to fully indemnify the municipality, its officers, the citizens of the municipality and Yerkes Associates.

We carefully read the Zoning Ordinance of every client municipality, alert for contradictions or inconsistencies that could lead to problems. If issues are found, we assist in the preparation and explanation of recommended amendments to the Zoning Code.

Our zoning officers prepare cases that appear before the municipal Zoning Hearing Board and present testimony before the hearing board if called upon.

Property Maintenance

Yerkes Associates is qualified to enforce a Property Maintenance Code for any of our clients that choose to adopt one. We work with the client to ensure that they carefully format an adoption ordinance that enforces the issues they wish to address but not create an enforcement nightmare.

As a model code not adopted by the PA UCC, the Property Maintenance Code may be adopted in whole or, as we recommend, carefully edited to achieve the desire result. The objective is to provide our municipal clients with a means to address specific issues of local importance without making the enforcement a financial burden to the taxpayers.
