Garage Sales 

Hosting a garage or yard sale is a fun way to clear out unwanted household items and allow them to have a new life with a different family.  Residents may choose to organize a single-family garage sale or invite additional families for a neighborhood yard sale.  This page provides information on the City Code for yard sales and some tips on hosting a sale.     

City Code applying to Yard Sales

Garage or yard sales are allowed in all residential areas in the city.  Each sale may last no longer than three consecutive days. Each residence is limited to four garage sales within a 12-month period.  Neighborhood garage sales are counted as one of the four sales.

Your HOA or manufactured home park may have regulations or guidelines on yard or garage sales as well.  Contact the property manager of the subdivision or park to learn more about those guidelines.  

Signs Advertising Yard Sales

The City Code allows for residents to place one sign no larger than six square feet on the property where the sale is taking place.  Also, residents can place temporary signs advertising the yard sale in the public rights-of-way, as long as the signs meet the City Code regulations:

  • Signs must be able to stand alone.  They cannot be attached to any public utility pole, street sign, utility box, fence, house, shed or tree.
  • Signs cannot have anything attached to them.
  • Signs cannot be placed in or on a street, sidewalk, or median.
  • Signs must be placed at least 50 feet away from all intersections and 5 feet away from the curb or edge of the road.
  • Signs may be displayed only from 5 a.m. on Fridays until 7 a.m. on the following Monday.
  • Signs can be no larger than 6 square feet in size (for example a 2’x3’ sign) and no taller than 4 feet in height.

Yard Sale Tips

Plan out the event.  About two to three weeks in advance, begin gathering the items you will sell, designate responsibilities among participants, and begin making signs.  Also, consider what you will do with unsold merchandise after your sale.

If you are interested in making a donation to a local charity or nonprofit, be sure to contact the organization beforehand to see which items will be accepted.  If you would like to dispose of large items, click here for information about the City's special collection service.

Team up!  Muilti-family or neighborhood sales draw more traffic.  Invite the neighbors to join in.

Advertise effectively.  Post signs that can be read easily.  Newspaper and online ads are also great sources to use.

Think like a customer.  Is the sale inviting and easy to browse through? Are things clearly marked? Are items priced to sell?  Make sure your garage sale is set up like one you would want to attend.

Don't forget the lemonade!  Refreshments such as lemonade, juice, or coffee help people feel invited and they may browse longer.
