Planning and Building Permit Costs for A New Custom Home or Accessory Dwelling in Danville, CA

At New Avenue we have paid over 30 different types of permits to get residential projects approved.  These are “normal” projects too such as additions, remodels, restorations, accessory dwellings accessory structures and custom homes.

One of the architects who is a partner at New Avenue’s recently completed in depth research for the permitting fees of a new Accessory Dwelling in Berkeley, CA.   Here are his findings from December, 2015.
