Special Qualifications

Because Mr. Harrington has acted as both a developer of his own properties and a general contractor for clients, he has a unique insight into the owner-builder relationship, as well as their differing perspectives about architects, engineers, planning commissions, and building departments.

He often consults regarding techniques that have been grandfathered but are not acceptable for new construction.
