New Construction >110%

New Construction >110% ( More Flexibility)

A Rebuild applies when you want to make significant changes—exceeding 110% of the previous structure’s square footage, height, or bulk. This includes major redesigns, layout changes, or expansions beyond what was there before.

Pros of Rebuilding:

  • Permit process is still expedited

  • ADUs may be allowed additionally

  • Can expand up to zoning limits (unless an HOA has stricter rules)

  • May suspend additional codes for flexibility

Cons of Rebuilding:

  • Must comply with current zoning (setbacks, height limits, etc.)

  • May require Coastal Commission approval if in a regulated zone

  • May require CEQA review

  • Gas lines may not be allowed – new homes must have electric ovens

Key Takeaway

  • Choose Reconstruction if you want to rebuild quickly and with fewer approvals, keeping your home largely the same.

Choose Rebuild if you want more flexibility to expand or redesign, but expect additional regulations.
