Search Coos County Parcels, Values & Deeds

Use Coos County’s official property tools to locate an assessment account, check ownership and situs information, compare Real Market Value (RMV), Maximum Assessed Value (MAV) and Assessed Value (AV), inspect the map and tax lot, review property taxes and trace recorded deeds.

The important part is knowing which county system to use after you find the parcel. This guide separates assessment records from tax payments, GIS parcel maps, deed records, zoning questions and value appeals—and shows what to click, record and verify at each step.

Search a property Decode RMV, MAV & AV Find deed records
Location check: this guide covers Coos County, Oregon, including property records for communities such as Coos Bay, North Bend, Bandon, Coquille, Myrtle Point, Lakeside and Powers. It does not cover Coös County, New Hampshire, which uses a different assessment and registry system.

Quick answer: use the Assessor Account Search first

For a normal Coos County property lookup, start with the official Assessor Account Search. Find the matching account, record the account number and Map & Taxlot ID, then use the value fields for assessment questions, ArcGIS for parcel context, the Tax Office for balances/payments and the County Clerk’s Digital Research Room for deeds and other recorded title documents.

Oregon value decoder

RMV, MAV and AV are not the same number

Oregon’s property-tax system does not use an Ohio-style fixed assessment ratio. Coos County calculates the value fields under Oregon rules. The taxable assessed value is generally the lower of RMV and MAV, subject to special assessment rules where applicable.

A simple example

Hypothetical RMV: $420,000

Hypothetical MAV: $260,000

Taxable AV: $260,000 because it is the lower value in this example.

This example explains the relationship only. It is not a valuation of any Coos County parcel.

How to read Oregon assessment values
Field
Meaning
What can change it
How to use it
RMV
Real Market Value—the Assessor’s estimate of market value as of the assessment date.
Market data, property characteristics, new construction and other appraisal factors.
Main value to analyze if you believe the county’s market-value estimate is wrong.
MAV
Maximum Assessed Value—the constitutional taxable-value limit.
Generally limited in annual growth, but qualifying property events can cause additional increases.
Compare with RMV to understand why taxable value may be lower than market value.
AV
Assessed Value used for taxation; generally the lower of RMV or MAV.
Changes when the RMV/MAV relationship changes or applicable special-assessment rules apply.
This is the key value used with applicable district tax rates.
SAV / MSAV
Specially assessed values that can apply to qualifying property.
Program qualification and statutory special-assessment rules.
Important for certain farm, forest and other specially assessed property.
3% rule—important nuance: Oregon generally limits annual MAV growth to 3%, but that does not mean every property’s tax bill can rise by only 3%. New improvements, partitions/subdivisions and other statutory property events can affect MAV, while tax rates and Measure 5 compression also affect the final bill.
Do not estimate Coos County tax as RMV × one countywide percentage. A property’s bill reflects its assessed value, the combined rates of the taxing districts in which that property sits, assessments and Oregon constitutional tax limitations.

Business personal property — immediate 2026 issue: Coos County states that after September 1, 2026, filed or amended 2026 business personal-property returns are no longer accepted for that year. As of August 29, this deadline is imminent. Late/non-filing penalties had already reached the county’s listed 50% level after August 1. Call 541-396-7916 promptly if this applies to you.
Tax bill & payment

Use the Tax Office after you identify the correct account

The assessment account explains the property and its value; the Tax Office handles tax amounts, payments, delinquency and tax statements. Coos County’s tax website warns that its online search data comes from the tax roll for informational use and is not itself the Tax Department’s certified official record.

Micro-steps to check or pay Coos County property tax

Open the official Coos County Taxes page Use the county page rather than an advertisement or third-party payment page.
Select “Pay Property Tax Here” This routes you into the county’s property-tax payment/search system.
Locate the same property account Compare the account number and property location before relying on a balance.
Check tax year and payment status Make sure you are looking at the intended tax year and determine whether a mortgage servicer or another payer has already posted a payment.
Compare the payment method cost Coos County currently lists a 2.49% convenience fee for credit/debit transactions and a flat $1.50 fee for an e-check.
Save payment confirmation Keep the confirmation number and payment date until the tax account reflects the payment.
Recheck the account if paying near a deadline If mailing, Coos County accepts the postmark as the paid date. Ask the post office for an immediate postmark when timing is close.
Online

Start from the county Taxes page. Confirm account and tax year before submitting.

Mail

In person / drop box

Tax Office is in the courthouse, second floor, Room 207. The county also lists a drop box to the right of the office door.

Past-due cost: Coos County currently states interest is 1⅓% per month, or 16% per year, on the past-due portion. Do not use an old balance when calculating what to pay; verify the current amount with the Tax Office.

GIS & cartography

Use the map to locate a tax lot—not to prove a legal boundary

Coos County Cartography maintains property-account mapping, plat-map information and taxing-district geography. The official ArcGIS aerial map is especially useful when a rural address is difficult to search or when you need visual parcel context.

Account context Use the map to connect a location with its parcel/account identifiers.
Map & Taxlot Save this ID for assessment, appeal and document-research workflows.
Taxing districts Cartography maintains district mapping that helps explain why tax rates differ by location.
Recorded changes Cartography processes ownership and mapping effects of deeds, partitions, divisions, consolidations and other recorded documents.
Sales research Coos County provides a Sales Comp Finder map useful for researching recent transactions.
Not zoning approval A map display does not decide whether a proposed use is permitted. That belongs with Planning/Community Development.
Critical boundary warning: Coos County explicitly says ArcGIS parcel lines are shown for assessment purposes only. They may not align with legal property lines on the aerial image. For a boundary dispute, purchase, fence placement or construction decision, use recorded deeds/plats and appropriate survey information—not the colored GIS line alone.

How to use the official ArcGIS map

Open the county ArcGIS Aerial Photo Map The link is provided directly by the Assessor.
Use the address search in the map Coos County’s own sales/foreclosure instructions point users to the address search at the upper-right of the interactive map.
Zoom to the correct parcel Compare roads, neighboring parcels and structures rather than selecting a tax lot from location alone.
Open parcel attributes Capture the Map & Taxlot/account identifiers that connect the mapped feature to assessment records.
Use deed/plat records for legal questions If the mapped outline appears to cross a driveway, fence or building, treat that as a reason to research—not proof that the physical feature is legally misplaced.
Open official ArcGIS map Open Cartography guidance
Local research trick

Coos County has a useful Sales Comp Finder that generic directories miss

If your real intent is to judge whether an assessment looks reasonable, a property-search page alone is not enough. Coos County publishes a GIS-based Sales Comp Finder that can help you identify recorded sales for comparison.

County-specific quirk: Coos County says the tool is titled Residential Comp Finder, but it can work for other properties too. Its instructions tell users to disregard the ordinary address search/filter prompts and instead enter a sales-price range and beginning/ending year sold, then click Apply.
Open the Assessor’s Sales and Foreclosures page Find the Sales Comp Finder link/instructions.
Enter a low-to-high sales-price range Choose a realistic range around the market segment you are researching.
Enter beginning and ending sale years Narrow the period to transactions relevant to your valuation question.
Click Apply Matching properties are highlighted on the map.
Click a highlighted property Coos County says the result can show Map & Taxlot, account number, sale price/date, deed reference, owner, situs, assessed value, estimated land/improvement RMV, classification and tax-code area.
Do not stop at “same sale price” Compare property type, location, size, improvements and sale timing. For an appeal, evidence should address market value as of the January 1 assessment date.
Open Sales & Comp guidance
Deeds & recorded documents

Assessment ownership is not a substitute for the recorded deed

The Assessor maintains ownership information for assessment administration, but the Coos County Clerk records documents affecting title to real property. When you need the deed, mortgage, release or another recorded instrument, move from the assessment account to the Clerk’s Digital Research Room.

How to trace a deed after finding the assessment account

Save owner names and any deed reference shown in county tools Exact names and an approximate transaction period reduce trial-and-error in the recording index.
Open the Digital Research Room The public system displays a disclaimer before document research. JavaScript may also be required for parts of the interface.
Accept the public-record disclaimer County search images/index information are convenient research tools, but the online image is not represented as a certified true copy.
Search the recording index Use party/grantor-grantee names, recording date or document/reference information available from the assessment/GIS research.
Open the matching document image Confirm legal description, parties, recording date and reference information rather than relying on the index title alone.
If an older record is missing online, do not assume it does not exist Coos County says indexing of documents prior to 1990 for electronic retrieval is still in progress.
Digital Research Room login/display problem: the County Clerk specifically recommends trying a different browser or clearing cache/cookies if the system does not work correctly.

Free fraud-monitoring tool

Set a same-day alert for newly recorded documents

Coos County’s County Clerk offers the Property Recording Alert Service (PRAS) at no charge. It can email you when a new document is recorded under a name you monitor and includes a direct link to the recorded document.

Free

The county currently charges no fee for PRAS enrollment.

Same-day alerts

Coos County says notices are sent the same day a matching document is recorded.

Review the document

An alert contains a direct link so you can determine whether the filing actually concerns your property.

Name-monitoring tip: monitor the exact owner-name variations commonly used in recorded documents. A common name can generate an unrelated alert, so always open and verify the document before assuming it affects your title.
PRAS does not stop a recording. It is a notification/monitoring service, not title insurance and not a mechanism that prevents a fraudulent document from being presented.
Sign up for PRAS Read PRAS guidance
Value appeal

Question the assessment before paying $35 to file a PVAB petition

Coos County recommends beginning with the Assessor. Staff can explain the valuation, and the county offers a free Request for Reappraisal/Appraisal Review. If the disagreement remains, a property owner or person with an interest in the property can petition the Property Value Appeals Board.

Open the property account Write down RMV, MAV, AV, account number and Map & Taxlot.
Identify the actual dispute Is the issue the county’s RMV estimate, a property characteristic, an omitted demolition, a special-assessment issue or something else?
Call the Assessor at 541-396-7900 Ask for an explanation and, when appropriate, use the county’s free appraisal-review process.
Build January 1 evidence PVAB evidence should address what the property was worth and its condition as of January 1 of the assessment year—not simply what it is worth months later.
Use relevant comparable sales or factual evidence Market transactions, appraisal evidence and corrected property facts are more useful than arguing that a neighbor pays less tax.
If unresolved, file PVAB by December 31 Coos County currently charges $35 for each account/petition.
Keep proof that the petition was filed PVAB activity is handled through the Coos County Clerk. Do not rely on an informal Assessor conversation to preserve the appeal deadline.

Business Personal Property page
Potential 2026 relief window: Oregon’s regular senior/disabled property-tax-deferral application deadline was April 15. Oregon allows qualified applicants to file a late application with the county through December 1 with a late fee. Because this guide is being reviewed in August 2026, that late-filing window may still be useful to eligible Coos County homeowners.
Deferral is not an exemption. Under Oregon’s program the state pays qualifying property taxes, a lien/security interest is placed on the property, and deferred amounts plus applicable interest/fees are ultimately repayable.

Why Oregon property searches may not use an “Auditor” office

County office titles differ across the United States. In Coos County, the practical property-record route is the Assessor → Tax Office → County Clerk workflow rather than a single county-auditor property database.

If you are comparing this workflow with another state or county, use our live county-office directory to identify which local office performs assessment, taxation or recording functions before following a generic “auditor search” instruction.

Coos County tax assessment and records FAQs

How do I search Coos County, Oregon property assessments online?

Open the official Coos County Assessor Property Search Online system. Search the correct parcel, then save the account number and Map & Taxlot ID. Use the property record to review ownership information, parcel details and RMV/MAV/AV. The portal requires JavaScript.

Why does the Coos County property search say JavaScript is required?

The official Property Search Online application depends on JavaScript. Enable JavaScript in your browser and refresh the page. If it still fails, try a current browser and use the Assessor page or ArcGIS map as an alternate starting point before calling 541-396-7900.

What is the difference between RMV, MAV and AV in Coos County?

RMV is Real Market Value, MAV is Maximum Assessed Value, and AV is Assessed Value. Under Oregon’s system, taxable assessed value is generally the lower of RMV and MAV, subject to applicable special-assessment rules. A property’s RMV therefore is not automatically the number on which its taxes are calculated.

When are Coos County property taxes due?

The county lists statutory installment dates of November 15, February 15 and May 15. For current-year taxes, Coos County states that when a due date falls on a weekend it moves to the next working day. The county also accepts postmark as the payment date.

How do I find a Coos County Map & Taxlot number?

Start with Property Search Online or the official Assessor ArcGIS aerial map. Locate the correct account/parcel and save the Map & Taxlot identifier. It is useful for appraisal questions, GIS research, appeals and connecting property information across county systems.

Are Coos County GIS parcel lines the legal property boundaries?

No. Coos County Cartography explicitly warns that ArcGIS parcel lines are for assessment purposes only and may not align with legal property lines shown by deeds, plats or surveys. Do not use the GIS outline alone to settle a fence, construction or boundary dispute.

Where can I search Coos County deeds and recorded land records?

Use the Coos County Clerk’s Digital Research Room. Search using owner/party names, recording information or a deed reference gathered from property research. Coos County notes that pre-1990 documents are still being indexed for electronic retrieval, so an older record may require additional Clerk assistance.

How do I appeal a Coos County property assessment?

First call the Assessor at 541-396-7900 and ask about the value and the free appraisal-review process. If the dispute remains, an eligible property owner or interested party can file a PVAB petition with the County Clerk by December 31. Coos County currently lists a $35 filing fee for each account/petition.

Can I find comparable property sales through Coos County?

Yes. The Assessor provides a Sales Comp Finder map. Coos County’s instructions say the tool labeled Residential Comp Finder can work for other properties as well: enter a sales-price range and beginning/ending sale years, click Apply, then inspect highlighted transactions and their property details.

How can I get alerts when a deed or other document is recorded under my name?

Use the Coos County Clerk’s free Property Recording Alert Service (PRAS). It sends same-day email alerts when a new recorded document matches a monitored name and provides a link to the document. An alert should still be reviewed because a same-name filing may relate to another person.

Information reviewed August 29, 2026: this guide was checked against the current Coos County Assessor, Tax Office, Cartography, County Clerk, Property Value Appeals Board, Business Personal Property, Exemptions/Deferrals, Recording Fees and PRAS pages, plus Oregon Department of Revenue property-assessment guidance.

Your actual bill depends on local school levies, voted millage, inside vs. outside millage splits, House Bill 920 reduction factors (HB 920), and special assessments. The 2026 Homestead general amount ($29,000) and enhanced amount ($58,000) reflect HB 187 inflation indexing — your county auditor's office may show slightly different transitional figures.
