Considering an Accessory Dwelling Unit (ADU) for your San Francisco home? It's a powerful way to add value and create much-needed living space in this densely populated city. As San Francisco continues to prioritize in-law units and housing density, ADUs are becoming increasingly popular in neighborhoods from the Sunset District to Bernal Heights. An ADU can generate rental income, provide space for family, or serve as a private home office. We know that the regulations in San Francisco can be complex, with specific zoning codes and permitting processes. Factors like lot size, existing building configurations, and street access will all influence your project's feasibility. We're here to help you understand these requirements. Don't let the process deter you from exploring this excellent opportunity. Call us today for a free estimate and let's discuss your ADU vision.

What affects the price

Building an ADU is a custom project, so costs vary based on your specific choices. Site conditions are the biggest factor; if your land requires significant grading, utility extensions, or foundation work, those expenses add up quickly. Choosing high-end finishes, custom cabinetry, or complex roof lines will also push the budget higher compared to a standard design. Prefabricated units often offer predictable costs, while custom site-built structures allow for more flexibility but can be harder to estimate upfront. Exact pricing confirmed free on the call.
