What are Markham's noise rules for renovations and construction?Under Markham’s noise bylaw, construction is allowed on Saturdays from 9 a.m. to 5 p.m. and is prohibited on Sundays and statutory holidays. Loud outdoor music is not allowed from 5 p.m. to 7 a.m. (9 a.m. on Sundays), and amplified sound at private events can run to 11 p.m. on Fridays and Saturdays. Work outside permitted times needs an exemption. Check the bylaw for weekday hours before planning work.
Renovations and infill builds are common on established Markham streets, so knowing the noise rules helps both owners and neighbours.
Michael John Lau, a REALTOR® with the Kaizen Real Estate Team, one of the most active real estate teams in Markham and York Region, shares these rules with clients planning renovations after closing.
