Can I convert my basement or room over my garage into an apartment? Or redesign my front walkway?
In some communities, adding or redesigning are common events and, depending on the extent of the change, are sometimes tacitly ignored and the city does not bother you, even though technically they are a zoning law infringement. (A particular common example is garage conversions to live-in rooms.) Again, to prevent future problems, and legal hot water, before you decide to undertake such a project, it pays to do all the up-front planning and research to make absolutely sure you will be permitted to do what you want and will comply with setbacks, height, esthetics and any other possible restrictions.
