Two Ways We Work
Existing buildings, or something new.
Both tracks are PE-stamped and engineer-led. Pick the one that matches your project.
Existing Buildings
Evaluations, retrofit, and inspections.
Ordinance compliance, ASCE 41 evaluations, soft-story and non-ductile concrete retrofit, and SB-326 / SB-721 balcony inspections for buildings that already exist.
New Design & Additions
New construction, additions, and ADUs — permit-ready stamped structural.
Foundation, framing, and lateral design for work that does not exist yet. We design the structure directly or work from your architect’s plans.

In Their Words
What clients say after a project closes.
Names withheld for client confidentiality — role, asset type, and city verified.
“Our SB-326 inspection was overdue and the board wanted a real engineer, not a checklist vendor. H2 turned a stamped report inside two weeks, walked our board through the findings, and flagged two repairs we’d otherwise have missed.”
HOA Board President
84-unit condominium · Oakland, CA
“Fee proposal arrived the morning after we called. SB-721 inspections at three properties were scheduled, performed, and reported in the same calendar month. Carrier accepted the reports on the first submission.”
Property Manager
3-property apartment portfolio · San Jose, CA
“Brought in for a litigation-support structural assessment on a contested HOA matter. The report read like a deposition exhibit — clear scope, defensible methodology, and findings tied to specific code citations. Settled before trial.”

Non-ductile concrete buildings: The 10-year deadline is here.
If your building was constructed before 1977 and you received an Order to Comply from LADBS, the 10-year structural analysis and retrofit plans deadline is approaching — with most orders issued between 2016 and 2018. Engineering evaluation takes 4–6 months minimum. Owners who haven’t engaged a licensed PE are running out of time to meet the milestone without enforcement risk.
