Who We Serve

Our Wealth of Knowledge Put to Work for You

The team at All County and Associates, Inc is a trusted source for our rapid and thorough responses, and our ability to handle a project big or small. We never deviate from our primary focus of helping our clients make informed decisions. Our most significant client groups include: Architects, Builder / Contractor, Developer, Homeowner, Home Inspector, Real Estate Agent


Too often, civil engineers and architects work independently of one another. This leads to unknown changes that impact both parties, cause delays or lead to higher costs. By partnering with ACA,  we are able to integrate the architect’s vision into the site, and bounce ideas off of one another from the start.


Whether you are looking to sell a home, construct something, or move to your dream home, all you have to do is give us a call to get started, and we’ll take care of the rest! We assist homeowners with boundary survey for buildings and fences, floodplain survey to evaluate if you are in a floodplain and if an Elevation Certificate (EC) may benefit you, and also sewage disposal (septic) system inspections. Visit our services page for more details on how we can help you with your home or property.



ACA’s experienced and knowledgeable staff help you avoid unexpected delays because of improper planning and regulations, as well as other pitfalls that can occur. We save you frustration, time, and money from start to finish.


As a home inspector, you are responsible for evaluating a tremendous amount in a small period. So what do you do when you come across something as critical as a sewage disposal (septic) system? These are unique and timely inspections. So put the responsibility into the hands of the trusted experts at All County and Associates! We know what to look for, from the integrity of the plumbing to the presence of a sump pump, and we are fast, knowledgeable, and thorough.


Regardless of the scope of the project, don’t break ground without understanding all the requirements. Whether residential or commercial, there are limitations and permitting requirements. This is where our expertise in local, state and federal regulations, combined with our innovative solutions, helps ensure your project’s success.


All County and Associates, Inc. is a trusted resource to many partnering real estate agents and organizations. Our goal is to help you learn about and better manage your clients’ potential property issues including sewage system inspections, boundary surveys, flood elevation surveys, and permitting. Property transactions are complex, timelines are short, and emotions run high. ACA helps empower real estate agents with information and resources.
