Cost to design, permit, and build a house in a landslide zone in Berkeley

We built a small backyard home in a Berkeley landslide zone. Here are the design plans and budget.

Anyone considering building in a landslide zone (or even on a steep lot) will face a wide range of expenses. Costs vary by project and site, so it can be hard to know what to expect. As a point of reference, here are the plans and budget for a completed landslide-zone project.

Frankly, it's expensive. The full cost of just the excavation, concrete piers, and foundation was close to $40,000.

For the full budget that includes every line item, see the pdf at the bottom at the bottom of this post.

This is the site plan for the backyard cottage.

This is the "elevation" of the front of the house.

This is a more detailed floor plan. A small area can go a long way with the right layout; note how much counter space is in this relatively small kitchen.

This shows the 12' deep concrete piers that had to be drilled, filled with rebar and concrete, then tied into the visible part of the foundation.
