"Jim is a great guy to work with!!! He was very understanding and responsive to all my questions and concerns. He oversaw the entire operation of removing a wall to open up the living area. This encompassed general demo and construction, electrical, resurfacing, matching texture and repainting. Followed by some special hardwood floor detail work. His team of workers are always excellent and considerate of us and our home. You will not be disappointed! It is very difficult to try and choose a contractor and I feel lucky to have found him!!"

"Efrain and David are fantastic! When our contractor was suddenly unable to continue with the job, David took over with a great positive attitude. He persistently worked with the city to get the building permit, finally ending a tedious 10 month process. Crews were here working every day. Each one of them was considerate, conscientious, and demonstrated a strong work ethic. Efrain and David communicated with us most days and were always accessible to us. My ADU is adorable and just what we wanted and I am sure that many contractors could have pulled it off. The important thing about Olalde is that they truly care and honestly want us to be happy."

FAQs for addition to existing structure building service projects in Lakeside, 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.
