ADU builder in Berkeley, CA

Fitting a second home into an established Berkeley lot

In North Berkeley and the central flatlands, an existing garage or rear-yard space can be the starting point. We measure the separation between buildings, locate service lines and plan an entrance that preserves privacy for both households.

Berkeley Hills properties need a closer look at terrain and wildfire mapping. Berkeley also provides parcel guidance covering landmarks, creeks and seismic hazards. We use those checks to identify what studies or design coordination may be needed.

Parcel research before Berkeley plan submission

The city’s Planning and Development staff provide land-use and building-permit guidance. We start by confirming zoning and parcel conditions, then coordinate the site plan with structural and energy documents. A landmark designation or mapped creek must be evaluated for the actual proposal, not treated as an automatic prohibition.
