🔎 Monroe County property search by address, owner or parcel
The official search is where most users should start. It can help you review owner details, mailing address, site address, legal description, land and building data, sales history, market value, assessed value, taxable value, exemption status and map access.

🧾 Property card decoder: what each field means
This is the section that helps users finish the task without guessing. Once you open the property record, use this decoder before calling the office or filing any form.
| Property-card field | What it means | What to do if it looks wrong |
|---|---|---|
| Parcel number | The unique ID used across search, GIS, tax estimator, tax bill, TRIM and VAB records. | Compare with deed, tax bill and TRIM notice before filing anything. |
| Owner name | Owner of record from recorded ownership information. | Check recent sale, deed recording, probate, trust or LLC status. Recent changes may not appear instantly. |
| Mailing address | Address where assessment and tax-related notices may be sent. | Use the official address-change process and submit a signed form. |
| Site address | Physical location used for search and mapping. | Compare with GIS, legal description and official records. |
| Legal description | Recorded land, lot or unit description. | For boundary, title or easement concerns, use a survey, title company or official records. |
| Land use / property use | Category used for appraisal review. | Collect photos, permits and use proof before contacting the Property Appraiser. |
| Building data | Living area, year built, construction, improvement or structure details used in valuation. | Prepare floor plan, permit, demolition proof, repair estimate or photos. |
| Sales history | Recorded transfers and sale amounts when available. | Remember that family transfers, partial interests or distressed sales may not reflect normal market value. |
| Exemptions | Homestead or other approved benefits applied to reduce taxable value. | Check filing confirmation, eligibility, deadline and exemption status before assuming an error. |
💡 Market value, assessed value, exempt value and taxable value
Many users see one value and panic. The property card can show different values because Florida assessment caps and exemptions do not work the same way as market value.
| Value term | Plain meaning | Why it matters |
|---|---|---|
| Just / market value | The appraiser’s estimate of market value. | This is usually the starting point for value disputes and comparable-sales review. |
| Assessed value | Value after assessment limits such as Save Our Homes or non-homestead caps. | A longtime homesteaded owner may have assessed value far below market value. |
| Exempt value | Value reduced by approved exemptions. | Missing exemptions can raise taxable value. |
| Taxable value | Value used by taxing authorities after applicable caps and exemptions. | This drives the ad valorem portion of the tax bill. |
| Non-ad valorem | Charges on the tax bill that are not based on property value. | A bill can feel high even when taxable value looks reasonable. |
🗺️ GIS maps and Florida Keys parcel due diligence
GIS maps help you visually understand the parcel, but they are not a legal survey. In Monroe County, map review is especially important because water access, canal location, island roads, conservation areas, condo units and mobile home parks can change how a property should be interpreted.
👤 Owner search, LLC lookup and responsible research
Owner lookup can help buyers, title users, landlords and homeowners verify a property record. It should still be used carefully because public records can include old mailing addresses, trust names, LLCs and similar owner names.
🧑 Individual owner
Try last name first. If results are broad, compare parcel number, site address, mailing address and last sale date.
🏢 LLC or trust
Search the exact entity name, then verify the company on Florida Sunbiz before relying on a mailing address.
🧩 Problem solver: what to do when something looks wrong
Use this section before calling the office. It helps you explain the issue clearly and bring the right proof.
| Problem | Likely reason | Best next step |
|---|---|---|
| Address search shows no result | Street suffix, unit, direction or punctuation may not match portal formatting. | Search only house number and main street name, then try owner or parcel number. |
| Owner name looks old | Recent sale, deed, probate or trust update may not be reflected yet. | Check official recorded documents and call with deed details if needed. |
| Mailing address is wrong | Address-change form was not filed, signed or processed. | Use the official mailing address change form and recheck the property card after processing. |
| Building size looks wrong | Sketch, permit or improvement data may need review. | Prepare photos, permits, floor plan or demolition/repair proof. |
| Homestead is missing | Application not filed, deadline missed, ownership/residency issue or status change. | Find filing confirmation and call the Property Appraiser before TRIM/VAB timing passes. |
| Tax bill is higher than expected | Non-ad valorem charge, discount month, escrow issue or taxable value change. | Separate property value from bill charges and check the Tax Collector record. |
| GIS parcel does not match expectation | Map layer, parcel split, condo unit, mobile home space or address mismatch. | Use parcel number and legal description; do not rely on GIS as a survey. |
📄 Homestead exemption: eligibility, documents and risk points
Monroe County explains that homestead exemption can provide up to $50,000 off assessed value for a property used as the owner’s primary residence. The first $25,000 applies to all taxing authorities. An additional exemption can apply when assessed value is at least $50,000, increases annually with inflation and is not applied to school district taxes.
| Situation | What it means | Action |
|---|---|---|
| New homeowner | You need qualifying ownership, residency and domicile. | Prepare documents before online filing. |
| Mobile home owner | Land and mobile home must be owned and titled identically; the mobile home must be declared permanent and an RP tag must be purchased one time. | Collect deed plus mobile home title or registration. |
| Partial rental | If part of the primary residence is rented, exemption may be prorated for the occupied part. | Ask before renting a room, unit or portion of the home. |
| Full rental | Rental property does not qualify for homestead, although other exemptions might apply. | Do not assume homestead remains if property becomes rental use. |
| Trust or title change | Adding/removing owners or moving property into a trust may affect homestead. | Contact the Property Appraiser before recording the change. |
| Probate / inheritance | Inherited exemption may be limited, and a new owner may need an original application. | File early and ask the office during probate rather than waiting. |
📈 Save Our Homes and portability: avoid expensive mistakes
Save Our Homes starts the year after a property receives homestead exemption. After the base year, assessed value generally cannot increase more than 3% or CPI, whichever is lower, unless reset events occur. Portability may allow a Florida homeowner to transfer all or part of the Save Our Homes benefit to a new Florida homestead, up to $500,000.
| Topic | Plain-English meaning | User action |
|---|---|---|
| Base year | The first year homestead is granted; just value equals assessed value. | Do not expect a Save Our Homes benefit in the first base year. |
| Annual cap | Assessed value increase is limited to the lower of 3% or CPI after the base year. | Compare just value and assessed value on the property card. |
| Reset event | Ownership, homestead or title changes can reset assessed value to just value. | Ask before deed, trust, spouse or ownership changes. |
| New construction | Additions or improvements can be added at 100% of market value in the year added. | Expect value change after major improvements or additions. |
| Portability limit | A Florida homeowner may transfer SOH benefit to a new Florida homestead up to $500,000. | Apply for portability when filing homestead on the new property. |
| Portability timing | The new homestead must meet official timing rules after leaving the prior residence. | Do not wait until after March 1 if you moved from another Florida homestead. |
💰 Tax estimator, tax bill payment and discount timeline
The Property Appraiser’s tax estimator is for planning. The actual tax bill and payment are handled by the Monroe County Tax Collector. Tax statements are normally mailed on or before November 1, and the gross amount is due by March 31.
🏠 Use Property Appraiser for
Market value, assessed value, taxable value, exemptions, parcel records, GIS, TRIM and tax estimator.
💳 Use Tax Collector for
Tax bill, payment, receipt, E-check, credit card fee, missing bill, delinquent tax and payment questions.
| Month / date | Tax-bill rule | Best action |
|---|---|---|
| On or before Nov 1 | Tax statements are normally mailed. | Search online if mail is missing; do not wait until delinquency. |
| November | 4% discount if paid in November. | Best time to pay if escrow is not paying for you. |
| December | 3% discount if paid in December. | Confirm tax year, parcel and payment method fee. |
| January | 2% discount if paid in January. | Save receipt after payment. |
| February | 1% discount if paid in February. | Do not rely on slow mail close to deadline. |
| March | Gross amount due; no discount applied. | Pay before March 31 if not escrowed. |
| April 1 | Taxes become delinquent. | Contact Tax Collector quickly if unpaid. |
💸 Non-ad valorem assessments: why a Keys bill can be higher than expected
Non-ad valorem assessments are charges collected on the tax bill that are not based on property value. In Monroe County, these can be important because wastewater, solid waste, stormwater, canal, PACE and improvement assessments may vary by area.
| Assessment type / area | Contact shown by Tax Collector | Why it matters |
|---|---|---|
| Florida Keys Aqueduct Authority wastewater districts | 305-296-2454 | Bay Point, Conch Key, Hawks Cay and Layton wastewater items can affect annual cost. |
| Monroe County wastewater / Stock Island / Cudjoe-related items | 305-292-4426 / 305-289-6051 | Wastewater assessments can be property-specific and area-specific. |
| Key Colony Beach stormwater | 305-289-1212 | Stormwater charges may appear separately from value-based tax. |
| Islamorada wastewater / solid waste / stormwater | 305-664-6446 | Islamorada parcels can have multiple local service-area charges. |
| Key Largo wastewater | 305-451-4019 | Key Largo wastewater phases may affect the yearly bill. |
| Key West solid waste / stormwater | 305-809-3967 | City service charges can increase the bill beyond taxable value. |
| Canal 266 assessment | 305-453-8774 | Canal-related charges can be parcel-specific. |
| PACE programs | 866-807-6864 / 561-630-4922 / 800-969-4382 | PACE items can affect buyer closing review and annual cost planning. |
| City of Marathon wastewater / stormwater / road items | 305-289-5005 | Marathon properties may include wastewater or road-improvement assessments. |
| Monroe County Solid Waste | 305-292-4536 | Solid waste charges affect final annual cost. |
📬 Mailing address change and record correction
A wrong mailing address can cause missed TRIM notices, tax statements and exemption-related letters. Monroe says the owner of record should complete and sign the mailing address change form. If the requester is not the owner of record, Power of Attorney for the owner must be attached.
⚖️ TRIM notice and VAB appeal evidence matrix
A TRIM notice is not the tax bill. It shows proposed taxes, values, exemptions, budget hearing details and petition deadline. Monroe says owners have 25 days from the mailing date to file a petition if they disagree with property value, and the office encourages contacting them first because many concerns can be resolved before filing.
| Issue | Evidence to prepare | How to explain it |
|---|---|---|
| Market value too high | Comparable sales, appraisal, photos, repair estimates, market data. | Show why the property would not sell for the listed value as of the valuation date. |
| Wrong building area or improvement data | Permit records, sketch, floor plan, demolition proof, photos. | Point to the exact field on the property card that appears wrong. |
| Storm or condition damage | Dated photos, insurance papers, repair estimates, inspection reports. | Show how the condition existed before or during the relevant valuation period. |
| Missing homestead or exemption | Application confirmation, ID, residency proof, ownership documents. | Confirm whether the issue is eligibility, late filing, missing document or processing. |
| Portability problem | Prior homestead details, abandonment date, prior assessed value, prior market value. | Confirm timing and ownership rules from the prior Florida homestead. |
| Classification issue | Use records, business records, leases, photos, maps or supporting documents. | Show why the property’s classification should differ from the record. |

❓ Monroe County Property Appraiser FAQs
How do I search Monroe County property records by owner, address or parcel?
Open the official Monroe County Property Search and search by address, owner name or parcel number. For exact results, use the parcel number from your tax bill, deed, TRIM notice or property card.
Why is my Monroe County taxable value lower than market value?
Taxable value can be lower than market value because assessment limits and exemptions may apply. Homestead, Save Our Homes and other benefits can reduce the value used for tax calculation.
What documents should I prepare for Monroe County homestead exemption?
Prepare deed, Florida driver license or ID showing the property address, vehicle registration, Social Security number, proof that you or your spouse are not receiving another residency-based exemption, co-owner addresses, mobile home title or registration if applicable, voter registration or declaration of domicile, and Permanent Resident Card if applicable.
Can a Monroe County mobile home receive homestead exemption?
Yes, if you own both the land and the mobile home and they are titled identically. Monroe also says the mobile home must be declared a permanent structure and an RP tag must be purchased one time.
Can renting, title changes or trust changes affect Monroe County homestead exemption?
Yes. Rental use, ownership changes, trust changes, inheritance, title changes or residency changes may affect homestead status. Contact the Property Appraiser before making changes that could affect the exemption.
What is Save Our Homes in Monroe County?
Save Our Homes is the Florida assessment limitation that can apply after homestead is granted. Monroe explains that assessed value increases are limited to 3 percent or CPI, whichever is lower, unless reset events occur.
How much Save Our Homes portability can transfer?
Monroe County explains that Florida homeowners may transfer all or part of a Save Our Homes benefit to a new Florida homestead, up to $500,000, when timing and ownership rules are met.
Why is my Monroe County tax bill higher than expected?
Your tax bill may include value-based taxes plus non-ad valorem assessments, such as wastewater, solid waste, stormwater, canal, road or PACE-related charges. Review the actual Tax Collector bill instead of looking only at Property Appraiser value.
How do I change my Monroe County property mailing address?
Use the official Address Change page. The owner of record should complete and sign the mailing address change form. If the requester is not the owner, a Power of Attorney for the owner of record may be required.
How do I appeal my Monroe County property value?
Review your TRIM notice and property card, collect evidence, contact the Property Appraiser if needed, then use the official Appeals/VAB page. Monroe lists a 25-day timing rule after notice mailing and a $50 filing fee per parcel unless an exemption applies.
