Planning and Building Permit Rules For a Remodel, Addition and Accessory Dwelling in Orinda, 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 June and July 2016.

We guarantee your project will be different!  This is a great starting point if you are researching.  Most people have never heard of all these fees.

Three phone conversations with Daisy Allen, Orinda Planning Department, over months of June and July, 2016

Q: What is the zoning district?

Setbacks and Dimensions

A: N/A

Q: Can we continue a wall of an existing structure within a setback? Is there a maximum length for walls

A: Vertically with an Exception Application. Per Daisy Allen, this would likely be granted considering the corner lot condition and existing non-conforming garage.

Q: What is the maximum height limit? Is there a max average height limit? Can we match the height of the existing house?

A: 27′ above grade. Limit follows topography. 27′ is measured to the mid-point of dormers or architectural elements.
