YearBuiltGuide helps US home buyers and owners understand what a house’s build year says about the materials inside it, and what to check before buying, insuring or renovating.
Why this site exists
A listing tells you the year a house was built, but not what that year means. Homes from different eras were built with different pipes, wiring, paint and insulation, and some of those materials are now known to fail early or to be hazardous when disturbed. The information is public, but it is spread across agencies, utilities and trade sources. YearBuiltGuide puts it in one place and turns it into a checklist you can take to an inspection.
Who writes it
YearBuiltGuide is written and run by Mario Rodríguez, an electrician with years of experience in power distribution networks and construction work. That background shapes how the site looks at a house: system by system, the way a field technician would.
What I am not: I am not a licensed home inspector in the United States, and I am not a lead or asbestos professional. Nothing on this site replaces an inspection by a licensed professional in your state.
How content is made
- Every date and figure links to a public source, preferably a government agency (EPA, CPSC, HUD) or a local water or building authority. If there is no reliable source, the claim is not published.
- Drafts are prepared with the help of AI writing tools and then checked line by line against the cited sources before publishing.
- The site does not give legal advice and does not give instructions for electrical work or for removing or sampling asbestos or lead.
- Pages are reviewed when sources change. If you find an error, please tell me.
