Nonconforming Development

Even if you don't intend to make any improvements to the site, the zoning code has a value of work trigger that could require site improvements. When the value of your interior improvements have a market value totaling more than $131,150 (adjusted annually), up to 10% of the project cost must be spent toward making the existing site development meet the current zoning code.

The project value for this purpose can be reduced by the cost of any required seismic or accessibility upgrades included in the project. Site work required by zoning could include improving or providing: landscaping, bicycle parking, pedestrian circulation systems, screening and/or paving. The zoning code calls a situation where those existing elements on a site don't meet current code requirements "nonconforming development".
