Carlsbad ADU
Design + Build.
Carlsbad is the rare coastal market where ADUs still pencil hard on rent and flat-out win on resale. Demand is strong; supply is tight. We specialize in making the coastal overlay process predictable.
A specialist ADU builder,
tuned for Carlsbad.
Carlsbad's zoning framework is favorable to ADUs outside the coastal overlay, and the city's rental market pulls from executive tech employers along the 5. Finished Carlsbad ADUs command the second-highest per-sqft rents in SD County.

Common questions.
01 How much does an ADU cost in San Diego?
Most detached ADUs in San Diego County land between $175,000 and $450,000 all-in (design, permits, construction) for 500–1,200 square feet. Garage conversions typically run $105,000–$250,000. Your ADU Property Potential Report gives you a real, lot-specific number within two weeks.
02 How long does the whole process take?
From the day we sign to the day you get keys, plan on 12–24 months. Roughly: 2 weeks for the property report, 1 month for design, 6–12 months for permits (the city owns this clock), and 4–8 months for construction.
03 Can I build an ADU on my property?
If you own a single-family lot in California, the answer is almost always yes — state ADU law is very homeowner-friendly. The harder question is how big, how many, and what’s actually profitable. That’s the report.
04 How many ADUs can I build on one lot?
Under current California law, most single-family lots in SD County can add one ADU plus one Junior ADU, and many qualify for up to four total units through state density bonus provisions. We screen for this in the Property Feasibility Analysis.
05 Do you handle the permits?
Yes — end to end. Plan sets, submissions, corrections, structural engineering, school fees, utility coordination. Our permit team has personal working relationships with every major SD County jurisdiction.
