Landscape and Accent Lights

Outdoor Lighting Bylaw Requirements

We urge you to think twice about using landscape and accent lighting and other lighting that isn't needed for safety and security. If you do use this kind of lighting, please comply with all the requirements!

Unshielded or Partially Shielded

  • Must be 250 lumens or less per fixture if used to uplight a tree, shrub or other landscape feature (Section 102-5B). Uplighting of building facades and walls is prohibited except for temporary holiday lighting (Section 102-6B(1)).*


  • Must be 2700K or less in color temperature (Section 102-4B) (2400K or less is recommended to be the most dark-sky and neighbor friendly)


  • If used to uplight a landscape feature, must be aimed and oriented so that the light points directly towards it (Section 102-5B)


  • Must be turned off between 11pm and 6am (or, in the case of nonresidential properties, within one hour of closing until one hour before opening) (Section 102-4D)


*There is a limit on the total lumens allowed for all fixtures (combined) that aren't fully shielded (see Section 102-4C(2)). For this reason, we recommend using fully shielded fixtures, whenever possible.  

Fully Shielded

  • Must not exceed 1500 lumens per fixture (5000 lumens on nonresidential properties) (Section 102-4C(3))*


  • Must be 2700K or less in color temperature (Section 102-4B) (2400K or less is recommended to be the most dark-sky and neighbor friendly)


  • Must be turned off between 11pm and 6am (or, in the case of nonresidential properties, within one hour of closing until one hour before opening) (Section 102-4C)


* There is a cap on the total lumens allowed per site (Section 102-4C(1)), all fixtures combined, so we recommend using only 50 to 300 lumens per fixture for this kind of lighting.
