The sewer key is printed at the bottom of Schedule 1, page 2

The sewer key — the legend that explains what each sewer code means — appears on the second page of Schedule 1 of your property tax assessment. It is a small table, usually positioned in the lower margin or footer area, that lists the code numbers and their corresponding sewer service types. You do not need to look anywhere else; it is part of the form itself.

If you are reading a printed copy of your assessment, flip to page 2 and scan the bottom. If you are viewing a digital PDF, scroll to the second page and look at the footer or lower section. The key typically shows codes like "1" for public sewer, "2" for septic system, "3" for cesspool, or similar designations depending on your municipality.

The reason the key sits on page 2 rather than page 1 is space — the first page holds your property details and the main tax calculation. The sewer code itself appears on page 1 in a small box or field, usually labeled "Sewer" or "Sewer Code," but the explanation of what that code means is always on page 2.

Key Takeaways

  • The sewer key is printed directly on Schedule 1, page 2, in the lower margin or footer section of the form.
  • The sewer code number itself appears on page 1 of your assessment, but the key that explains it is on page 2.
  • You do not need to contact your assessor's office or search online to find the key — it is included with your form.
  • If your printed copy is unclear or the key is cut off, your municipality's website usually posts a full version of Schedule 1 with a legible key.

What the sewer codes actually mean

Sewer codes tell the tax assessor — and you — what type of wastewater system serves your property. The specific codes vary by state and county, but the most common are public sewer (connected to a municipal system), septic (a private underground tank), and cesspool (an older, less common system). Some municipalities also code for properties with no sewer service at all, or for properties in transition between systems.

The code matters because it can affect your property tax assessment. A home on public sewer may be assessed differently than one on septic, because public sewer service has a cost to the municipality and is reflected in how the property is valued. The code also tells you what you are responsible for maintaining — a public sewer means the town handles the main line, while a septic system is your responsibility.

Understanding your sewer code is especially important if you are planning renovations or repairs. A septic system requires pumping every three to five years and eventual replacement, which can cost thousands. Public sewer has no such maintenance burden on the homeowner. The code on your Schedule 1 is the official designation that determines which rules explore to your property.

If the key is missing or illegible on your copy

If your printed Schedule 1 is faded, cut off, or otherwise unclear, the easiest step is to visit your municipality's assessor website. Most towns post a blank Schedule 1 form with a clear, full-size key. Search "[your town name] assessor Schedule 1" or "[your county] property tax assessment form."

If the online version is also unclear, you can contact your local assessor's office directly. They can tell you what your sewer code means in one phone call. The assessor's office number is usually listed on your tax bill or on your town's website under "Assessor" or "Assessment Department."

Some municipalities also mail replacement copies of your assessment if the original is damaged or lost. Call the assessor's office and ask them to send you a fresh copy with a legible key. This takes a few days but ensures you have an official, clear version.

Why the key is important to check

Reviewing the sewer key helps you understand what type of system your property has and whether the assessment reflects that correctly. If your property is on septic but the form shows a public sewer code, or vice versa, that discrepancy could affect your tax bill. It is worth a quick look to make sure the code matches reality.

The key also helps if you are buying or selling a property and need to understand what the current owner pays for sewer service. A septic system, for example, requires regular maintenance and eventual replacement, which is a cost the buyer should know about. The code on Schedule 1 is the official record of what system serves the property.

If you discover an error in your sewer code, correcting it now can prevent problems later. Some municipalities charge different tax rates based on sewer type, or they may reassess your property if the code is wrong. A quick review of the key against your actual system takes minutes and can save you money.

How to read the key once you find it

The sewer key on page 2 is straightforward: it lists numbers or letters in one column and the sewer type in the next. Find your code number on page 1, then locate that same number in the key and read across to see what it means. Most keys are organized numerically or alphabetically, so scanning takes only a few seconds.

Some municipalities use single digits (1, 2, 3), while others use letter codes (P for public, S for septic, C for cesspool). A few use longer codes like "PS" or "NS." Whatever system your town uses, the key will show you exactly what your code means. If the key is unclear about what a code represents, the assessor's office can clarify in writing.

Frequently Asked Questions

What if I cannot find page 2 of my Schedule 1?

Schedule 1 is always two pages. If you only received one page, contact your assessor's office and ask for the complete form. You may also read it from your town's website. The key will be on the second page of any complete copy.

Do different towns use different sewer codes?

Yes. One town might use "1" for public sewer and another might use "P." That is why the key is printed on your specific form — it tells you what your municipality uses. Never assume a code means the same thing in a different town.

Can I change my sewer code if it is wrong?

If the code does not match your actual sewer system, contact your assessor's office with proof of what system you have. They can file a correction, which may affect your assessment. Bring documentation like a septic system inspection report or a letter from your town confirming public sewer service.

Is the sewer key the same every year?

The key itself — the list of what each code means — stays the same year to year. Your property's code may change if your sewer system changes, but that is rare. Check the key on your current year's form to be sure.
