Short answer: This falls under the Ampliación y/o Modificación category, which requires a full structural
engineering package and receives more scrutiny than a standard remodel permit.
Why it matters: Vertical additions change the structural load on a home originally engineered for its
current footprint — which is exactly why this category gets closer review.
What to check:
● Get a structural engineer involved before finalizing second-story design plans
● Ask whether your home’s existing foundation and structure can support the addition
● Confirm HOA design review alongside the municipal permit, since both typically apply
Bottom line: A second story isn’t a cosmetic addition in the permitting process — it’s a structural one,
and the paperwork reflects that.
