What should you verify before planning an ADU in San Francisco? A property’s layout, existing structures, and applicable rules can shape your options before design or budgeting begins. This adu development guide starts with those early checks, helping you replace assumptions with a clearer view of your project.
That $150,000 contractor bid for your California ADU might actually be a $220,000 project in disguise. It's a common frustration to realize that a quote often ignores the site-specific realities of your property, leaving you to discover the hidden costs of building an adu the hard way. You're likely feeling cautious about low-ball estimates and stressed by the complexity of local building codes. It's completely normal to fear running out of money mid-build when the financial finish line keeps moving.
Check your property and see what's possible.
