"We are very pleased with our whole house remodel performed by our contractor, Rick Simmons of Coastline Construction. We received four bids from various contractors which were all competitive. We chose Rick for various reasons including that he was easy to communicate with and that he uses his own very skilled employees, no subcontractors. We completely remodeled the kitchen, the main and secondary bathroom, laundry room and installed new flooring throughout that required grinding and leveling the concrete slab. Every wall and ceiling was retextured and painted. It was a HUGE job. Rick is a hands-on contractor who stopped by the house 3-4 times a week (sometimes everyday!). Rick kept us up to date on scheduling and every addition we made to the scope of work was clearly documented in change orders that we discussed with him. We had a good idea of what we wanted design-wise and the end result reflects that vision."

FAQs for second story addition building service projects in San Francisco, CA

Converting a vaulted ceiling into a second floor requires three to six months from planning to completion. The process begins with several weeks of design and engineering, followed by permit applications, which vary in processing time by location. 

Construction itself spans several months, including framing, systems installation, and finishing work. Weather conditions, contractor availability, and inspection schedules can all influence your project timeline.

Several factors could make your conversion challenging or impossible. Inadequate roof support structures, insufficient foundation capacity, or problematic truss configurations might require prohibitively expensive modifications. 

Some homes lack the minimum ceiling height (12 feet at the lowest point) needed for functional second-floor spaces. Building code restrictions in your area might also limit conversion possibilities, particularly in historic districts or homes with specific architectural designations.

Begin with professional assessments from both an architect and a structural engineer who will evaluate your home's specific characteristics. They'll examine existing framing, measure available headroom, assess load-bearing capacity, and identify potential obstacles like HVAC ducts or plumbing vents. 

These experts will also review local building codes to determine feasibility. Their preliminary analysis provides crucial information about structural requirements and potential limitations before you commit to the project.

Whether you'll need temporary housing depends on several factors, including the project's scope and your tolerance for construction disruption. Major structural work creates significant noise, dust, and potential utility interruptions that many families find challenging to live with. Safety concerns may also arise during certain construction phases. 

Some homeowners successfully remain by isolating the construction zone and establishing clear work schedules. Discuss living arrangements with your contractor early in the planning process to make informed decisions.
