"Tal was highly recommended by a friend of mine. He came to our house with a portfolio of all the beautiful remodeling jobs he had done. He sent a detailed proposal only a few days later. We had the first floor of our home remodeled which included: kitchen, living room, dining room, family room, and powder room. We had the fireplace totally redone with an electric insert installed. We had luxury vinyl flooring installed ,the popcorn ceiling removed ,recessed lighting, and walls painted. It all looks amazing I feel like I have a new house. Tal was wonderful. He helped us pick out the flooring and the quartz countertops to complement the white shaker cabinets I chose. Everyone that was involved in the remodeling were fantastic. The workers were all very professional and were there every day, except weekends) Tal came every day to check on the progress. He let me know what was going to be done that day and who was coming to do it. Tal always answered my text messages immediately when I had questions too. It took a total of about 7 weeks. They finished on my birthday! When it is time to remodel the 2nd floor we will definitely Choose Bay Builders . (I'm hoping next year) I have recommended them to several friends and neighbors.

FAQs for addition to existing structure building service projects in Loma-mar, CA

Converting an existing space into a laundry room is more affordable than building a new addition. While new additions start at $5,000, renovating an existing space for laundry use can begin at $1,300. 

Your specific costs will depend on whether plumbing and electrical connections exist nearby, the quality of finishes you select, and whether any structural modifications are needed. Always budget extra for unexpected issues, particularly in older homes where hidden problems might surface during renovation.

The smallest practical size for a new laundry room addition is 35 square feet, which provides enough space for basic appliances and minimal storage. For renovations utilizing existing space, smaller footprints might work with space-saving solutions like stacked appliances. 

A standard-sized laundry room of 60 square feet offers more comfort and functionality, allowing for counter space and storage cabinets. The optimal size depends on your household needs and available space.

Yes, adding a laundry room requires several permits, particularly for new additions. You'll need building permits, plus specific permits for electrical work, plumbing installations, and possibly HVAC modifications. 

Requirements vary significantly by municipality, so consulting with your local building department before starting work is essential. Proceeding without proper permits can result in fines, mandatory removal of completed work, and complications when selling your property.

The timeline for completing a laundry room addition varies based on project complexity, contractor availability, and permit processing times. Factors that can extend the schedule include material delivery delays, weather conditions, and unforeseen structural issues discovered during construction. 

Renovating an existing space often requires less time than building a completely new addition. Working with an experienced contractor who can coordinate various tradespeople efficiently helps keep your project on schedule.
