ALTA Survey: The Complete Guide
What ALTA/NSPS land title surveys are, who needs one, the full Table A breakdown, and what the process involves — from a licensed Florida PSM.
Quick Answer
An ALTA survey (ALTA/NSPS Land Title Survey) is a comprehensive boundary and title survey that meets nationally recognized standards set by the American Land Title Association and the National Society of Professional Surveyors. ALTA surveys cost $2,500-$6,000+ in Florida and take 7-14 business days.
ALTA surveys are standard for commercial real estate transactions, construction loans, and refinancing. They include boundary determination, improvement location, easement mapping, flood zone classification, and optional Table A items — going well beyond a basic boundary survey to protect lenders, buyers, and title companies.
What Is an ALTA Survey?
An ALTA survey — formally an ALTA/NSPS Land Title Survey — is the most comprehensive type of land survey performed in the United States. The standards are published jointly by the American Land Title Association (ALTA) and the National Society of Professional Surveyors (NSPS), creating a nationally uniform standard that lenders and title companies rely on for commercial real estate transactions.
Unlike a standard boundary survey, which focuses on establishing property lines and corners, an ALTA survey integrates boundary determination with title research, improvement mapping, easement identification, flood zone classification, and zoning analysis into a single certified document. The result protects all parties in a real estate transaction — the buyer, lender, and title company — from survey-related risks.
National Standard
ALTA/NSPS standards are recognized by lenders, title companies, and attorneys across all 50 states — providing consistency regardless of where the property is located.
Title Integration
The survey is tied directly to the title commitment — every exception, easement, and encumbrance in the title report is located and shown on the survey plat.
Certified Document
A licensed PSM certifies the survey to the specific parties named in the title commitment — buyer, lender, title company, and their successors and assigns.
Who Needs an ALTA Survey?
ALTA surveys serve multiple parties in a real estate transaction. Here are the primary stakeholders who request or require them.
Commercial Lenders
Banks and lending institutions require ALTA surveys before funding commercial mortgages, construction loans, and refinancing. The survey protects the lender's collateral by confirming the property boundaries match the deed and identifying encumbrances that could affect the loan.
Commercial Property Buyers
Buyers of office buildings, retail centers, industrial properties, and multi-family complexes use ALTA surveys for due diligence. The survey reveals encroachments, easements, and zoning issues before closing — information that can change the purchase price or kill the deal.
Title Insurance Companies
Title underwriters rely on ALTA surveys to identify survey-related exceptions to title coverage. Without a current survey, the title policy may exclude coverage for boundary disputes, encroachments, or unrecorded easements — leaving the owner exposed.
Real Estate Attorneys
Attorneys representing buyers, sellers, or lenders in commercial transactions use ALTA surveys to verify that the property description in the deed matches conditions on the ground. The survey is a critical part of legal due diligence.
Developers & Builders
Developers acquiring land for new construction need ALTA surveys to confirm buildable area, setback compliance, utility access, and easement locations before designing site plans. Table A items like zoning compliance (6a/6b) and utility locations (11a/11b) are essential.
Property Owners Refinancing
When refinancing commercial property, lenders typically require an updated ALTA survey — or at minimum, a recertification of an existing survey. This confirms no new encroachments or changes since the original survey.
ALTA/NSPS Minimum Standard Detail Requirements
The ALTA/NSPS standards define two categories of requirements: mandatory baseline elements (Sections 5 and 6) that every ALTA survey must include, and optional Table A items that the client selects based on the transaction's needs.
Current edition: The 2026 ALTA/NSPS standards became effective February 2, 2026, replacing the 2021 edition (effective February 23, 2021). The 2026 update includes clarifications for modern surveying technology (LiDAR, RTK-GPS), expanded language around renewable energy infrastructure, and refined Table A descriptions. The core requirements and numbering remain consistent.
Mandatory Baseline (Every ALTA Survey)
Boundary determination: Locate and establish all property boundaries per the legal description in the title commitment.
Rights-of-way and access: Identify and show all rights-of-way and evidence of access to public ways.
Visible improvements: Locate all visible improvements (buildings, structures, paving) on the property and within 5 feet of boundaries.
Easements and encumbrances: Locate all recorded easements and servitudes identified in the title commitment.
Surface utilities: Show surface evidence of underground utilities (manholes, valve boxes, utility markers).
Certification: The PSM certifies the survey to the parties named in the title commitment, bearing the surveyor's seal and license number.
Optional Table A Items
Table A items expand the survey scope beyond the mandatory baseline. There are 19 active items (plus item 20 for custom requirements) covering everything from flood zones to parking counts to building heights. Your lender and title company will specify which items are needed. Each additional item adds fieldwork, research, or both — increasing the survey cost and timeline. See the complete Table A breakdown below, or visit our ALTA survey cost guide for item-by-item pricing.
Complete Table A Items Breakdown
Every Table A item explained — what it is and why it matters. For pricing, see our ALTA survey cost guide.
| Item | Description | Why It Matters |
|---|---|---|
| 1 | Monuments placed (or a reference to an existing monument) at all major corners of the boundary of the surveyed property. | Ensures permanent physical markers exist at every property corner so boundaries can be found in the future. |
| 2 | Address(es) of the surveyed property if disclosed in the title commitment or documents provided. | Confirms the street address matches the legal description — catches addressing errors before closing. |
| 3 | Flood zone classification per FEMA with community and panel number, date, and suffix. | Determines flood insurance requirements. Critical for lenders — properties in flood zones require mandatory insurance. |
| 4 | Gross land area of the property (to the appropriate degree of mathematical precision). | Confirms total acreage or square footage. Discrepancies between deed area and measured area can affect property value. |
| 5 | Vertical relief with spot elevations at all corners and along property lines. | Shows the topography of the site. Important for drainage analysis, building design, and grading plans. |
| 6(a) | Setback, height, and floor area ratio restrictions from a current zoning report or letter. | Documents what zoning allows — maximum building height, minimum setbacks from property lines, and total buildable area. |
| 6(b) | Setback, height, and floor area ratio restrictions shown graphically on the survey plat. | Draws the zoning restrictions directly on the map so you can see exactly where you can and cannot build. |
| 7(a) | Exterior dimensions of all buildings at ground level. | Documents the exact footprint of every building on the property — essential for confirming improvements stay within boundaries. |
| 7(b)(1) | Square footage of the exterior footprint of all buildings at ground level. | Provides the measured building area — useful for comparing against tax records, insurance coverage, and floor area ratio calculations. |
| 7(c) | Height of all buildings above grade at the closest point to each property line. | Confirms buildings comply with height restrictions. Important when structures are near setback lines. |
| 8 | Substantial features observed in the course of the survey — parking areas, signs, swimming pools, landscaped areas, etc. | Documents everything on the property beyond buildings. Identifies potential issues like a pool overlapping an easement. |
| 9 | Number and type of parking spaces, both on surface lots and within structures. | Verifies parking meets zoning requirements. Critical for commercial properties where parking ratios are enforced. |
| 10 | Exterior dimensions of all buildings at each floor level, including story heights. | Provides per-floor measurements for multi-story buildings. Used for lease calculations and building code compliance. |
| 11(a) | Location of utilities (surface evidence) serving the property — manholes, poles, hydrants, valves. | Maps visible utility infrastructure. Essential for site planning, construction access, and identifying utility easements. |
| 11(b) | Underground utilities from plans provided by the client — water, sewer, gas, electric, telecom. | Locates buried utilities that could conflict with construction. Requires the client to provide utility company as-built drawings. |
| 13 | Names of adjoining property owners from current tax records. | Identifies neighbors for easement negotiations, boundary agreements, and construction notification requirements. |
| 14 | Name of party or parties in possession of the property if different from the record owner. | Reveals tenant occupancy or adverse possession situations that could complicate the transaction. |
| 16 | Evidence of access to a public way, street, or highway. | Confirms the property has legal access to a public road. Landlocked properties without access can be difficult or impossible to develop. |
| 17 | Location of significant observations within 200 feet of the property boundary. | Documents nearby conditions that could affect the property — retaining walls, drainage structures, or improvements on adjacent land. |
| 19 | Offsite easements or servitudes disclosed in title documents that benefit or burden the property. | Maps easements that cross neighboring properties but serve this property (like a shared driveway or utility line crossing a neighbor's land). |
Items 12, 15, and 18 were removed in prior editions and remain reserved. Item 20 is blank for client-specific custom requirements.
The ALTA Survey Process: 8 Steps
From title commitment to certified plat delivery — here is what a licensed PSM does to complete an ALTA/NSPS survey.
Title Commitment Review
The surveyor receives the title commitment, deed, and supporting documents from the title company or client. This identifies the legal description, recorded easements, liens, and exceptions that the survey must address.
Deed and Easement Research
The surveyor researches the chain of title at the county clerk's office, reviews prior surveys, recorded plats, and adjacent property deeds. All recorded easements, rights-of-way, and encumbrances are identified and located.
Table A Item Coordination
The client, lender, and title company specify which Table A items are required. The surveyor reviews the scope and discusses any items that may require additional documents (zoning letters, utility plans) from the client.
Field Reconnaissance and Monumentation
Using GPS receivers, total stations, and metal detectors, the survey crew locates existing monuments, measures boundary lines, and identifies property corners. Missing monuments are set (iron rods with PSM caps).
Improvement and Feature Mapping
All buildings, structures, paving, fences, walls, utilities, and other improvements are measured and located relative to the boundary. Encroachments — where improvements cross boundary or easement lines — are identified.
Table A Item Completion
The surveyor completes each requested Table A item: flood zone determination, zoning compliance analysis, adjoining owner research, parking counts, building dimensions, and any other selected items.
Drafting, Calculations, and Quality Control
Office work to prepare the survey plat: boundary calculations, area computations, easement plotting, improvement dimensioning, and annotation of all findings. A second PSM reviews the work for accuracy.
Certification and Delivery
The licensed Professional Surveyor and Mapper (PSM) signs, seals, and certifies the survey to the parties named in the title commitment — typically the buyer, lender, and title company. The certified plat is the final deliverable.

How to Read an ALTA Survey
An ALTA survey plat is a dense, information-rich document. Here is what each major section contains and how to interpret it. For general survey reading skills, see our guide to reading land survey maps.
Title Block
Located in the lower-right corner. Contains the surveyor's certification, PSM seal and license number, survey date, legal description reference, and the names of parties the survey is certified to (buyer, lender, title company).
Boundary and Dimensions
The property boundary is shown as a bold line with bearing (direction) and distance (length) labels on each segment. Curves show radius, arc length, and chord data. Monuments are marked with symbols indicating whether they were found (existing) or set (new).
Easements and Encumbrances
Shown as hatched or dashed areas with labels referencing the recording information (Official Records Book and page number). Each easement is cross-referenced to the title commitment exception it addresses.
Improvements
Buildings, pavement, fences, walls, pools, and other structures are shown with dimensions and distances to the nearest property line. Any improvement that crosses a boundary or easement line is labeled as an encroachment.
Table A Notes
A schedule on the plat lists which Table A items were selected and any modifications to the standard language. This is where you find flood zone classification (item 3), zoning data (items 6a/6b), and adjoining owner names (item 13).
Certification Language
The ALTA/NSPS standards prescribe specific certification language. The surveyor certifies that the survey was made in accordance with the Minimum Standard Detail Requirements, identifies the edition used, and names the certified parties.
When Is an ALTA Survey Required?
ALTA surveys are not legally mandated by Florida law, but they are standard practice — and often contractually required — in these situations:
Commercial Property Purchase
Standard due diligence for office, retail, industrial, and multi-family acquisitions. Required by most commercial lenders and title underwriters.
Commercial Mortgage
Banks require ALTA surveys before funding commercial mortgage loans. The survey protects the lender's collateral by confirming the property description matches actual conditions.
Construction Loans
Lenders require ALTA surveys before disbursing construction loan funds. The survey confirms buildable area, setback compliance, and utility access before construction begins.
Commercial Refinancing
When refinancing commercial property, the new lender typically requires an updated or recertified ALTA survey to confirm nothing has changed since the original survey.
Title Insurance Issuance
Title underwriters use ALTA surveys to identify survey-related exceptions. Without a survey, the title policy excludes boundary, encroachment, and easement coverage — leaving significant gaps.
High-Value Residential
Jumbo mortgages, waterfront properties, and estates with complex boundaries may require ALTA surveys even for residential transactions, depending on the lender's requirements.

Florida-Specific ALTA Survey Requirements
Florida ALTA surveys must comply with both the national ALTA/NSPS standards and the state's own surveying regulations. Here are the key Florida-specific requirements.
PSM Licensing (Chapter 472, Florida Statutes)
All ALTA surveys in Florida must be performed by or under the direct supervision of a Professional Surveyor and Mapper (PSM) licensed by the Florida Board of Professional Surveyors and Mappers. The PSM must maintain professional liability insurance and complete continuing education requirements.
Minimum Technical Standards (Rule 5J-17, FAC)
The Florida Administrative Code sets additional minimum technical standards that apply to all surveys performed in Florida, including ALTA surveys. These cover accuracy requirements, monument standards, and documentation requirements beyond what ALTA/NSPS specifies.
Florida State Plane Coordinate System
Survey measurements in Florida are tied to the Florida State Plane Coordinate System (NAD 83). Florida has three zones (East, West, North) based on geography. The coordinate system ensures all surveys can be accurately related to each other and to the national geodetic framework.
Flood Zone Determination
Florida's extensive flood zones make Table A item 3 (flood zone classification) particularly important. Many Florida properties are in Special Flood Hazard Areas (SFHA) — zones AE, VE, AH, or AO — which trigger mandatory flood insurance requirements and affect construction standards.
Coastal Construction Control Line (CCCL)
Coastal Florida properties may require the surveyor to locate the CCCL — a line established by the Florida Department of Environmental Protection seaward of which construction requires special permits. The CCCL is particularly relevant for ALTA surveys on beachfront commercial properties.
