In San Francisco, a city with a density of 17323 people per square mile, the first thing licensed, insured pros check on arrival is your property's existing foundation and structural soundness. This is crucial for determining the feasibility of adding an accessory dwelling unit, especially in older neighborhoods like the Inner Sunset. They'll also confirm your property's current zoning to ensure ADU construction is permitted. Identifying potential points for utility connections—water, sewer, and electricity—is another early step. This initial assessment helps lay the groundwork for a successful project. Next, the pros develop detailed plans tailored to your property and needs. These plans cover everything from the unit's layout to its integration with your main home. They then manage the complex permitting process with the city of San Francisco. Once permits are secured, the construction phase begins. This involves specialized crews handling all aspects of building, from foundation work to interior finishing. The focus is always on quality and compliance with strict building codes. One quick call gets you a free quote — no obligation. Same-day appointments are often available in San Francisco.

The materials you choose—from siding to kitchen finishes—also change the math significantly. Whether you’re building a detached unit or converting an existing garage shifts the permit requirements and structural work needed. We provide exact pricing confirmed free on the call.
