先谢过回帖的好心人。
查了一下，76年后的属Manufactured Home。建造标准蛮高。我看的00年左右，应用百分之几的rule呢？
Manufactured homes - Homes built AFTER 1976 should, technically, no longer be referred to as Mobile Homes but instead are Manufactured Homes and are built to a higher standard of quality than yesterday's "Mobile Homes".
Manufactured Homes are built entirely in a factory under the federal building code administered by the Department of Housing and Urban Development (HUD). These homes are constructed to meet the Federal Manufactured Home Construction and Safety Standard Act of June 15, 1976. The federal standards regulate manufactured housing design and construction, strength and durability, transportability, fire resistance, energy efficiency and quality. The HUD Code also sets performance standards for the heating, plumbing, air conditioning, thermal and electrical systems. HUD is the only federally-regulated national building code. Each home or segment of a home is labeled with a red tag that is the manufacturer's guarantee the home was built to conform to the HUD code. On-site additions, such as garages, decks and porches, often add to the attractiveness of manufactured homes and must be built to local, state or regional building codes.
又查了一下，Manufactured Home 寿命30-55 年。
