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.

The cost of building an ADU in San Diego can vary widely depending on size, design complexity, finishes, and site conditions. While online sources may offer general ballpark estimates, the best way to understand what’s realistic for your property and budget is through a personalized consultation. We’ll help you explore options that align with your goals—whether you're aiming for a compact rental unit or a high-end addition for extended family.
Typical timeline ranges are: Design and permitting phase: 2-4 months (varies based on local approval processes) Construction of room additions: 2-4 months depending on size and complexity ADU construction: 4-6 months for detached units, 3-5 months for attached conversions Your project manager will provide a detailed timeline specific to your project's scope and requirements.

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.

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.

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.
