Full Breakdown
Projects in the Hawaii Capital Special District, covering the downtown blocks around the State Capitol and Iolani Palace, go through design review under ROH § 21-9.30-4. Reviewers apply set landscaping standards, height precincts, and a 'contextualism' design guide covering roof form, architectural style, facade treatment, color, texture, and signage so new buildings read as compatible with the historic precinct.
Violations & Fines
Building without required design review approval or violating an approved design condition is enforced through the Department of Planning and Permitting's standard Land Use Ordinance permit and stop-work process.
