Home rewiring in Howard County starts with identifying the circuits, checking for aluminum wiring, and defining the scope for a permit.
The wiring date matters more than the house date
The U.S. Consumer Product Safety Commission (CPSC) identifies 1965 through the mid-1970s as a period when new homes, additions, and new or rewired circuits may have used aluminum wiring. Homes built before 1965 are unlikely to have original aluminum branch wiring, but that does not date every later circuit in the house.

For a Howard County home with additions or past renovations, the original build date alone cannot identify the wiring. The research could not count local homes with aluminum branch circuits: census data groups homes by decade and does not identify the wire inside them. A county housing statistic is not a diagnosis of an individual home.
What the aluminum study actually measured
A survey cited by CPSC found that aluminum-wired homes built before 1972 were 55 times more likely than copper-wired homes to have an outlet connection reach the study's fire-hazard conditions. The study did not develop information for aluminum-wired homes built after 1972.

This is a finding about outlet connections in the surveyed homes. It is not a statement that every Howard County house from that period has aluminum wiring, or that its chance of a house fire is multiplied by that figure. The scope and limits appear in CPSC's Repairing Aluminum Wiring.
How the county counts the work
Howard County lists residential alterations and additions at a $50 flat permit fee. For work involving no more than 10 outlets, it waives the application fee. Where a job has more than 50 outlets together with a service change or subpanel installation, the residential flat-rate schedule applies instead.
The schedule also lists a $50 non-refundable application fee and a 10% technology fee on permits. The technology fee excludes the application fee and the base fee for amendments.

These categories make the scope important. A quote should name the circuits to be replaced and count the outlets. It should also say whether the work includes a service change or subpanel. The alteration fee alone is not a whole-house rewiring price. The research found no reliable county-specific contractor price for that job, and no published inspection count or sequence that applies to every residential project.
Every figure above carries its own source and the date it was read.
