Factor	Kitchen Remodeling	Home Additions
Typical investment	$40K – $109K	$138K – $322K
Calendar end-to-end	20–40 weeks	28–57 weeks
Adds square footage?	No — same footprint, new finishes / systems	Yes — net new conditioned sq ft
Adds a kitchen / bath?	Kitchen only	Yes — typically, but optional
Rentable as a separate unit?	No — improves the primary residence only	Only if scoped as an ADU; an addition alone is not rentable as a unit
Permit pathway	Santa Monica Building & Safety — standard residential alteration permit	Santa Monica Building & Safety — discretionary plan check, overlays apply
Disruption to main house	High during the 4–8 cooking-down weeks	Moderate–high — tie-in wall is open during framing
Typical resale impact	strong — high cosmetic ROI, no sq-ft change	strong — primary-residence value grows with sq ft and bed/bath count
