Unpermitted Barns and Structures
Unpermitted barns, covered arenas, shade structures, and utility buildings are common on horse properties and represent a significant risk that buyers routinely underestimate. A structure that was built without a building permit has no record of code compliance, no inspected foundation, no verified structural adequacy, and no legal standing as a permitted improvement.
Lenders treat unpermitted structures with caution — appraisers may exclude them from value, and some lenders require their removal before funding a loan. After purchase, the buyer may receive a notice from the county building department requiring the structure to be permitted retroactively, brought into compliance with current code, or demolished.
Retroactive permitting is possible in some cases but requires a permit application, inspection, and potentially significant structural upgrades to meet current code. The cost of bringing an unpermitted 10-stall barn into compliance can exceed the cost of building a compliant structure from scratch in some scenarios.
Buyers should request building permit records for every enclosed structure on the property and verify through the county building department that permits were issued and that final inspections were completed. Permit records are public documents available at the county level. A seller who cannot produce permit documentation for enclosed structures should be treated as if those structures are unpermitted until confirmed otherwise.
Why Unpermitted Structures Are So Common on Horse Properties
Unpermitted barns and equestrian structures are disproportionately common on rural horse properties for several reasons. Rural properties developed before aggressive code enforcement in Arizona counties were frequently improved without permits because enforcement was rare and neighbors were unlikely to complain. Property owners who built structures for personal use — a shade structure for their horses, an extra stall added to an existing barn — often did not understand that permits were required for enclosed structures. In some cases, prior owners obtained permits for the initial barn but not for subsequent expansions or modifications. The result is a high prevalence of partially permitted or entirely unpermitted structures on properties that have changed hands multiple times without permit disclosure or investigation.
The sale of a horse property does not reset the permit compliance clock. Unpermitted structures on a property that was sold five times without anyone raising the permit issue are still unpermitted — the passage of time and changes in ownership do not legalize a structure that was never permitted. County building departments in Arizona maintain permit records indefinitely, and a permit search at the county building department will show what has been permitted, what has not, and whether final inspections were completed on permitted work. Buyers who skip this search are accepting risk that prior buyers chose to ignore, not risk that has been resolved by the passage of time.
Resolving Unpermitted Structures Before and After Closing
The most buyer-favorable approach to unpermitted structures is to require the seller to resolve the permit status before closing. Sellers can apply for retroactive permits — sometimes called "as-built" permits — for structures that were built without permits but that meet current code requirements. The retroactive permitting process involves submitting plans, paying fees, undergoing inspections, and potentially making modifications to bring the structure into compliance. If the structure cannot be retroactively permitted — because it fails to meet current setback requirements, structural standards, or other code provisions — the seller must either modify it to achieve compliance or disclose the situation and negotiate a price reduction that accounts for the buyer's remediation cost.
When sellers are unwilling to retroactively permit structures before closing, buyers can negotiate a price reduction that reflects the estimated cost of retroactive permitting and any required modifications, or they can request that funds be held in escrow pending permit resolution after closing. Buyers who accept unpermitted structures without a price adjustment or escrow holdback are accepting the full remediation cost and risk. The risk includes not just the permitting cost but also the possibility that retroactive permitting proves infeasible — requiring demolition at costs that significantly exceed the value the structure would have contributed if it had been properly permitted from the beginning.
Key Risks
- Unpermitted structures may be excluded from appraised value or require removal by lenders.
- Counties can order retroactive permitting, code compliance upgrades, or demolition after closing.
- Retroactive compliance costs can exceed the value of the structure in complex cases.
- Buyers must independently verify permit records through the county building department.
