Expand Your Living Space, Enhance Your Lifestyle


Why Invest in a Home Addition or ADU?
- Customized Living Solutions - Create spaces specifically designed for your family's unique needs rather than compromising with your home's current layout.
- Avoid the Costs of Moving - Expanding your current home often costs significantly less than selling, buying, and moving to a larger property.
- Substantial Property Value Increase - Well-designed additions typically return 60-80% of their cost immediately in added home value.
- Rental Income Potential - ADUs can generate $1,500-$3,000+ monthly in rental income in San Diego's strong rental market.
- Multi-generational Living Options - Create private, dignified spaces for aging parents or adult children that maintain independence while keeping family close.
- Work-From-Home Optimization - Develop dedicated, professional work spaces that separate your professional and personal life.

Frequently Asked Questions
About Home Additions & ADUs
What types of home additions are most popular in San Diego?
The most requested additions we build include:
- Primary bedroom suite additions that create luxurious retreats
- Kitchen expansions that open up living spaces for modern lifestyles
- Second-story additions that maximize lot usage in space-constrained neighborhoods
- Home office additions for the growing remote workforce
- Detached and attached ADUs for rental income or multi-generational living
During your consultation, we'll help determine which addition type best addresses your specific needs and property constraints.
How much does an ADU typically cost in San Diego?
How long does it take to build an addition or ADU?
Can I build an ADU on my property in San Diego?
Most single-family residential properties in San Diego can now accommodate at least one ADU under California's supportive legislation. Factors affecting eligibility include lot size, existing structures, setback requirements, and local overlay zones. During our initial consultation, we'll assess your property's specific potential for ADU development.
Will my property taxes increase with an addition or ADU?
Additions and ADUs typically result in some property tax adjustment, but often in a favorable way. Under California law, only the new addition (not your entire property) is reassessed at current market rates. For many homeowners, the rental income or utility of the new space far outweighs the modest tax increase. We can provide general guidance on tax implications during your planning process.
Do you handle all the permitting for additions and ADUs?
Absolutely. We manage the entire permitting process, including:
- Zoning verification and variance applications if needed
- Architectural and structural engineering plans
- Title 24 energy calculations and compliance
- All required city or county department approvals
- Coordination of inspections throughout construction
Our comprehensive approach eliminates the stress and confusion often associated with the permitting process.
