Doing the work
Learn what you need to know when undertaking your project, including details about inspections and how to set up your job site for success.
For Change of Use or Change of Occupancy
You'll need an inspection for all Change of Use or Occupancy permits, even if you're not doing any construction. This ensures the building meets all requirements for its new use.
Your permit will expire if no inspection takes place within 180 days. You can request an extension if needed.
Once the inspection is approved, you’ll receive a new Certificate of Occupancy for your records. See the next section for how to schedule inspections.
During your construction project
Help minimize impacts on others during your construction project. This includes your neighbors, your neighborhood, and the public. Here are a few ways to reduce disruptions:
- Control construction noise:
- Construction is allowed between 7 a.m. and 6 p.m., Monday through Saturday, with a maximum noise level of 85 dBA measured from 50 feet away. If you check your own equipment, use a reliable noise meter with “A” weighting and measure from the correct distance. These meters are available at most hardware and electronics stores.
- Keep the site clean:
- Regularly clear debris and litter from your site. Prevent trash from blowing into streets or neighboring properties. Clean up mud and debris to keep sidewalks and streets safe for pedestrians and drivers.
- Reduce glare from lighting:
- Bright construction lighting can be distracting to drivers, pedestrians, and neighbors. Use shields to keep lights focused on the work area and to reduce glare on nearby properties and streets.
- Post emergency contact info:
- Place a sign at the site entrance with a clear phone number for the project manager. Be sure to include a night and weekend number for emergencies.
