Adding a second story is the biggest structural change you can make to a home. It is not a framing project β it is a foundation and engineering project that adds living space above.
In Clairemont, La Mesa, and El Cajon, we see 1950s single-story homes where owners want bedrooms upstairs instead of losing yard. The existing foundation was built for one story. It is not ready for two.
Here is what a licensed second-story addition requires:
1. Soils report and structural engineering β existing footings must support the new load. Many do not. Underpinning is common.
2. Framing plan signed by a licensed civil engineer β shear walls, hold-downs, and roof tie-offs to current code.
3. Full permit set β plans, structural calcs, Title 24 energy. Plan check takes 4-8 weeks.
4. Rerouting of plumbing, electrical, and gas through opened walls.
5. Temporary shoring during roof demo.
The difference between a CSLB licensed contractor and an unlicensed builder on a second story is liability. If the structure fails, the unlicensed builder is gone. Insurance does not cover unpermitted work.
Cali Dream Construction is CSLB licensed and insured. We pull permits, engineer to code, and pass framing inspections the first time.
Planning a second-story addition? Start with a structural assessment of your existing foundation. That tells you what is possible and what it really costs.
