Determing The Age Of A House

Determing The Age Of A House

A common question i get asked is: How old is my home?

Houses are often given face lifts through repairs, replacement and renovations which can cover the age of your house. This is a reason why home inspections are important and the professionals have some tricks which i will be sharing with you. These are just are few tricks to find out a home’s age.

1) Houses building in the last 25 years will often have a sticker on the outside of the electrical panel with the possession date. Stickers are used to establish Ontario New Home Warrantee Program possession date. If you are sure the water heater or furnace is original the gas inspection sticker on either of these appliances would indicate the age of the home.

2) Thermal windows usually have a metal strip that separates the two panes of glass. On the metal strip you can find the date of manufacture and CMHC number. Check several windows. If the windows are original then this date could be used to indicate roughly when the house was built. Otherwise it could mean when the windows were last upgraded.

3) If you have knob and tube wiring then you can be sure your home is pre 1940s. If your electrical outlets have two prongs, your wiring does not contain a ground, and you do not have knob and tube then your house is from 1940s-1960s. If your electrical outlets have 3 prongs, your electrical wiring has ground, then your home is built after 1960s.

4) An easy way to date to find is from the toilet. Porcelain toilets usually have a date stamped on them. Remove the lid from the tank and the date is usually stamped on the underside of the lid. Also you may find the date stamped on the inside of the tank. If the toilet is not original to the house then it may only indicate when the bathroom was last updated.

5) If your neighborhood was a subdivision you can find nearby bridges or underpasses with a date. This usually indicates when the neighborhood was developed.

6) Find a nearby sewer drain grate, many of these drain grates have a date stamped on them. This may indicate when the sewers were installed.

6) Most houses built with concrete block foundations are pre 1970. Most subdivision homes built after 1970s have poured concrete foundations. In Ontario most brick homes were solid masonary contruction up until 1970. After that most houses were brick veneer construction.
