Unless the wiring in the building has been fully updated, this building likely has wiring that predates the late 1980's. Branch circuit wiring installed in buildings built prior to the late 1980s is typically rated for a maximum temperature of only 60 degrees Celsius. This includes non-metallic sheathed (Romex) wiring, and both BX and AC metal-clad flexible wiring. Knob and tube wiring, typically installed in homes built prior to 1950, may be rated for even lower maximum temperatures. Newer electric fixtures including lighting and fans typically require wiring rated for 90 degrees Celsius. Connecting newer fixtures to older, 60-degree-rated wiring is a potential fire hazard. Repairs for such conditions may involve replacing the last few feet of wiring to newer fixtures with new 90-degree-rated wire, and installing a junction box to join the old and new wiring. It is beyond the scope of this inspection to determine if any such incompatible components are installed. Based on the age of this building, be aware that such components may be present.

In 1978, federal laws were past to prohibit use of lead and asbestos in building materials. Manufacturers of building materials were allowed to sell existing stocks of materials that were manufactured with lead and asbestos, so even buildings constructed as late as the mid-1980's could possibly contain lead or asbestos. Identification and testing for lead and asbestos and other environmental testing is beyond the scope of this home inspection. If you wish to seek additional information, I recommend contacting an environmental lab or industrial hygienist.

Ground rod connections were noted at the exterior. The ground rods looked to be fully driven and connections looked standard,

During the home inspection, I try and test a representative sample of the smoke alarms by using the test button on the alarms. This is NOT an accurate test of the sensor just a test to see if the unit is powered. For reliability, fire marshals recommended updating smoke alarms every 10 years and changing batters bi-annually. The latest data indicate that we should be using photo-electric technology in our smoke alarms for improved fire detection and to reduce problems with false alarms which can lead to disabling of this important safety system. Unfortunately, the alarms have to be removed to determine if they are photo-electric or ionization types. It is surprisingly complex to accurately test a smoke alarm system and determine the reliability, age, and type of sensor technology used, especially as many homes can have half a dozen or more alarms throughout the house. A complete evaluation of smoke alarms is beyond the scope of this inspection. For optimal fire safety, I recommend taking control of these important safety devices and learning about how to service and maintain your smoke alarm system to keep the building occupants safe.

This house has a gas forced air furnace. A critical component to all combustion equipment like this is the heat exchanger. This is the welded clam-shell piece of metal inside the furnace that contains the products of combustion so that moisture, carbon monoxide and other products of combustion do not mix with interior air and get safely vented to the exterior. Heat exchangers on modern furnaces have an average life expectancy of 15-20 years. Unfortunately, heat exchangers are buried inside of heating equipment; they are not visible and specifically excluded from a home inspection.

Please note that when the sewage discharge type is listed here, it is listed based on public records and disclosure. It is always possible that the system is not as it is listed; for example, a property could be listed as a public sewer system when in fact it is on a private septic system. This is unlikely, but is another reason why we recommend further evaluation of all sewage discharge systems.

This shows the listing plate on the water heater.

The temperature and pressure relief valve is arguably one of the most important safety devices in your house. Should the thermostats fail inside your water heater, the TPRV allows excess pressure to "blow off," which will prevent catastrophic build up of temperature and pressure which can make water heaters explosive. I do not test the "blow off valve" during inspection as there is a risk it could stick open and testing could cause the need for a repair. Manufacturers of these relief valves recommend that these be tested annually. You need to decide for yourself if this is the type of annual testing you wish to perform.

During inspection of the crawl space, every effort is made to inspect the entire space. Visual inspection of crawl spaces is difficult and limited as access is often restricted by pipes, ducts and sub-floor insulation as well as limited clearances.
