"Glenn and his crews built an ADU for me in less than 3 months. His subcontractors were clean, friendly and professional. Their work was exceptional. They worked some of the hottest days of the year in July and August to ensure that the job was done in a timely manner. The job foreman was prompt to ask my opinion and ensure that my wishes were accomplished. The crews were well aware of the regulations for constructing an ADU and met the regulations in a timely manner. All permits were signed in a timely manner, inspections were scheduled in a timely manner and crews were ready and in attendance. I would definitely recommend Glenn and his crews to anyone planning projects large or small. I would hire him again for similar projects."

Addition to existing structure building services FAQs

How far you can push a room depends on the structure you choose. A cantilevered bump-out can extend 24 inches before building codes require its own footing or foundation. Anything longer needs engineered support and a permit. Check local codes or consult with a structural professional before finalizing plans to ensure your design remains safe and compliant.

Most bump-outs are completed within one to four weeks, even with minimal electrical, plumbing, or HVAC work. Their compact size means less demolition, simpler inspections, and fewer weather-related delays compared to a full-scale addition. Your contractor can provide a more precise timeline once they have determined the scope, materials, and permit schedule, but plan on having the extra square footage ready in approximately a month.
