Home Additions in Sacramento, CA

Q: How is a home addition budget determined?+

Budget depends on size, structure, foundation, exterior tie-ins, utilities, access, design and engineering, permit fees, finish selections, occupied-home protection, and concealed conditions. A property review and written proposal replace generic price assumptions.

Q: Does a Sacramento home addition require a permit?+

Residential additions generally require plans, permit review, inspections, and address-specific verification. The property jurisdiction and exact scope determine the required documents and reviews.

Q: How is the home addition timeline determined?+

The schedule depends on feasibility, design decisions, engineering, permit review, procurement, site access, inspections, weather, trade coordination, and the approved construction scope.

Q: Can I stay in my home during addition construction?+

Sometimes. The answer depends on access, structural openings, utility interruptions, dust and noise controls, weather protection, household needs, and the phase of work. The written plan should define protection, shutdowns, unavailable areas, and cleanup.

Q: What should I prepare before requesting an addition estimate?+

Prepare the address, the problem the new space should solve, available plans or photos, must-have features, a budget boundary, preferred timing, and household access needs. Field measurements and property research still need to be completed.

Q: How do I compare home addition proposals?+

Compare the same property assumptions and proposed scope. Review design and engineering responsibilities, foundation and structural work, exterior tie-ins, utilities, allowances, permits, inspections, exclusions, concealed-condition procedures, schedule assumptions, payment milestones, protection, cleanup, closeout documents, and warranties.

Create more room for the way you live. US Construction plans and builds Sacramento home additions, with design roles, permit responsibilities, and construction scope clearly defined for your property.

I didn’t know we had to get a permit for renovating my house but remodeling the bathrooms and kitchen, adding a new wall was required to have plan and permit, Us construction handled everything for me…

Robert KimballGoogle review

Choosing US Construction for our home remodel (two bathrooms and a full kitchen) was the best decision. The crew was exceptionally professional, keeping us informed throughout the entire process. … The final outcome is incredible; our new kitchen and bathrooms look like they belong in a magazine.
