Permit History: What It Tells You About a House

Public, free, and one of the most revealing checks available.

Every municipality keeps records of permitted work. They are public, generally searchable by address, and most buyers never look.

They are worth looking at, because they tell you something no inspection can: what the owners said they were doing, when, and whether anyone verified it.

What the record shows you

  • What work has been permitted and when. A roof permit from six years ago is corroboration of a seller’s claim.
  • Whether permits were finalized. This is the one people miss. A permit that was issued but never signed off means work was started under permit and never inspected to completion — which is in some ways worse than no permit at all, because the record shows an unresolved item.
  • What is not there. Visible work with no corresponding permit is the finding that matters most.

The things most often done without permits

  • Converted garages.
  • Enclosed patios turned into living space.
  • Added rooms and casitas.
  • Electrical work, particularly sub-panels and circuits added for pools, workshops or additions.
  • Water heater and mechanical replacements.
  • Structural alterations — walls removed without engineering.
  • Pools, spas and significant hardscape.

Why it actually matters

Safety. The inspection process exists because some mistakes are dangerous. Structural work done without engineering and electrical work done without inspection are the two that matter most.

Insurance. An insurer may take a position on damage arising from unpermitted work.

Resale. This is where it bites. When you sell, a buyer’s agent may check permits, an appraiser may notice square footage that does not match records, and a lender may ask questions. Unpermitted additions sometimes cannot be counted in the home’s square footage, which affects value directly.

Enforcement. A municipality can require unpermitted work to be brought into compliance, which may mean opening up completed finishes so an inspector can see what is behind them.

What to do if you find something

Not necessarily walk away. Unpermitted work is common, and much of it is perfectly sound. The question is what it is and what resolving it involves.

  • Establish what was done and how. An inspector or contractor can often tell you whether the work appears competent.
  • Ask the municipality what retroactive permitting involves. Many have a process. It may require opening up work for inspection, bringing it to current code, or engineering sign-off.
  • Price it. If resolution is a real cost, it belongs in the negotiation rather than in your first year of ownership.
  • Consider what you are actually buying. If a listing counts an unpermitted conversion in its square footage, you may be paying for area that will not count when you sell.

How to check

Most Valley municipalities offer online permit search by address. County records cover unincorporated areas. It takes a few minutes and costs nothing.

Do it before you write the offer where you can, and certainly during the inspection period. Compare what the record shows against what you can see — the gap between them is the finding.

If you are selling

Permits you hold are an asset. Assemble them, along with invoices and warranties, and provide them. It removes the uncertainty a buyer would otherwise price in.

If there is unpermitted work in your history, understand that it is likely to surface, and that disclosure obligations apply. Addressing it on your own timeline is generally better than during someone else’s inspection period.

Common questions

How do I check permit history?

Most Valley municipalities have an online permit search by address, and county records cover unincorporated areas. It is public, usually free, and takes a few minutes. Compare what the records show against what you can see at the property.

Is unpermitted work a deal-breaker?

Not usually. It is common, and much of it is competently done. What matters is what the work is, whether it is safe, and what resolving it would involve — which is a cost to establish and negotiate rather than a reason to walk automatically.

What does a permit that was never finalized mean?

That work began under permit and was never inspected to completion. It leaves an open item on the record and can complicate a sale. Ask the municipality what closing it out requires — sometimes it is straightforward, sometimes it means uncovering finished work.

This is general information to help you ask better questions about a specific property. It is not an inspection, an engineering opinion, an appraisal or legal advice, and it does not replace the licensed professionals who provide those.
