Engineer Certification Letters — Common Questions | Oasis Engineering
What Is an Engineer Certification Letter? An engineer certification letter is an official document prepared by a licensed professional engineer (PE) that verifies the structural condition, code compliance, or safety of a specific element of your property. These letters are often required by building departments, insurance companies, lenders, or during real estate transactions. At Oasis Engineering, we specialize in providing engineer letters to help homeowners, builders, and developers resolve permit issues, document repairs, or meet state and local code requirements. Common Engineer Letters We Provide: ✅ Engineer Letter for Permit Closure If you’ve completed work without final inspections or your permit remains open, most jurisdictions require an engineer letter to close the permit. We inspect the work and, if compliant, issue a letter stating it meets applicable codes. ✅ Engineer Affidavit for Unpermitted Work Unpermitted work can delay property sales, refinancing, or trigger code enforcement. Our licensed engineers can inspect the work, assess code compliance, and provide an affidavit to help legalize the situation and support retroactive permits. ✅ Structural Engineer Letter for Code Compliance We routinely issue structural letters confirming that repairs, additions, or modifications meet applicable building codes—whether for walls, framing, foundations, or general structural safety. ✅ Foundation Certification Letters For manufactured or mobile homes, FHA loans, HUD programs, or county requirements often mandate a foundation certification. We provide engineer letters confirming the foundation meets permanent or regulatory requirements nationwide. ✅ Truss, Roof, or Structural Repair Letters Roof certifications and truss repair engineer letters are common after storm damage, leaks, or alterations. We inspect and certify repairs or existing conditions for insurance, real estate, or compliance purposes. ✅ Engineer Letters for Roofing In-Progress Inspections This letters can officially verify that the roofing work meets all required standards, serving as an acceptable substitute for the missing permit in-progress inspections from the City or County. When Do You Need an Engineer Letter? ☑ Permit closure for completed but uninspected work☑ Buying or selling a property with unpermitted improvements☑ Structural changes, repairs, or safety concerns☑ Manufactured/mobile home foundation certifications (HUD/FHA compliance)☑ Insurance claims after storm or accident damage☑ Meeting city or county code requirements If you’re unsure, we’re happy to review your situation. Can You Provide Engineer Letters Remotely? Yes—we offer remote or virtual engineer letters when allowed by code and based on documentation, photos, or site videos. For certain projects, especially when ample documentation, data, plans or reports are available, remote service saves time and money.
