Codes, Regulations, and Professional Practice
Codes, Regulations, and Professional Practice
This domain tests legal and ethical practice: accessibility, building and zoning codes, permits, contracts, standard of care, liability, licensure, and professional responsibility. Expect scenario questions about scope and duty.
Core rules
- The standard of care is what a reasonably prudent landscape architect would do under similar circumstances, not perfection or a guarantee.
- Contracts define scope, deliverables, fees, schedule, and risk allocation. Changes in scope should be documented and agreed before extra work.
- Accessibility standards set minimums for routes, ramps, landings, clearances, and surfaces. Code minimum is a floor, not a design goal.
- Permits may be required for grading, drainage, demolition, right-of-way work, and structures. Approvals can carry conditions that must be tracked.
- Only licensed professionals should stamp or sign documents they are qualified to prepare. Ethics require disclosure of conflicts and accurate representation of qualifications.
Worked example
A ramp must rise 30 inches. At the maximum 1:12 slope, the run is 30 feet, and landings are required at the top, bottom, and intervals along the rise. A proposed 28-foot run cannot meet the slope without redesign. The reasoning: convert rise to run using the ratio, then check landing and handrail requirements. The design response is to lengthen the run, regrade, or change the route, not to round down the slope.
Traps
- Treating code minimums as design quality.
- Performing extra services without a written scope change.
- Stamping work prepared by others without review.
- Ignoring permit conditions after approval.
- Making verbal assurances that exceed the contract.
