Over-the-Counter Bathroom Permits
Walnut Creek offers over-the-counter permits for simple scopes of work, including minor non-structural interior remodels and plumbing, electrical and mechanical work. These are typically reviewed within 3 to 5 business days. A bathroom remodel that keeps the walls in place often fits this path. Moving walls, adding a window or changing structure needs full plan check.

Bathrooms for Postwar Walnut Creek Homes
Walnut Creek grew quickly after World War II, from about 2,500 residents in 1950 to nearly 10,000 by 1960, and much of its housing comes from that era. Neighborhoods like Parkmead, Tice Valley, Walnut Heights and Larkey Park have bathrooms that benefit from new layouts, curbless showers, double vanities and modern ventilation. In Rossmoor, most homes are cooperatives or condominiums, so association approval is part of planning.
