We have been serving Auburn and Sacremento Valley for more than 25 years, we specialize in ADUs) -auxillary dwelling units,- new additions, and garages. we focus on you and your project. Call today, you'll be glad you did.

"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."

FAQs for addition to existing structure building service projects in Colfax, CA

Yes, you can add a bathroom on a concrete slab, but the crew will need to saw-cut the slab, trench in new supply and drain lines, and then patch the concrete without weakening the foundation. Working with an experienced plumber and concrete pro keeps the structure intact and helps the new bathroom pass inspections.

schedule covers planning, permits, framing, rough-ins, finishes, and punch-list items. 

Larger spaces or extensive plumbing and electrical upgrades can stretch the timeline, while a simple powder-room conversion may wrap up faster. Hiring licensed pros helps keep the schedule on track and the work up to code.

The best location depends on how your family uses the space. An upstairs bath keeps nighttime trips close to the bedrooms, while a first-floor powder room is handy for guests and everyday traffic. 

Think about where plumbing lines already run, how much square footage you can spare, and what layout changes fit your budget. A pro can map out the smartest spot and handle any code hurdles.

With the right planning, you can carve out a bathroom in almost any part of the house. A successful addition requires sufficient space, proper ventilation, and access to plumbing and electrical systems. Structural modifications and adherence to building codes are essential. 

This process demands careful planning and the coordination of specialized professionals who ensure that the new space meets all code requirements and functional needs.

Under specific conditions, adding an extra bedroom can boost home value more than adding a bathroom. Home value is driven by overall configuration, market demand, and functional balance. A new bedroom influences the property’s appeal in different ways, while an additional bathroom enhances living convenience. Evaluating the current layout and market trends determines the optimal choice for maximum value.
