Existing Buildings, Maintenance, and Unsafe Structures
Working with existing buildings
- Existing-building provisions separate repair, alteration, addition, and change of occupancy, because each carries a different compliance level.
- Many codes apply requirements by work area rather than building-wide, but change of occupancy, substantial alteration, or a change to a more hazardous group can trigger broader upgrades.
- Accessibility obligations follow alterations through path-of-travel requirements, capped by a cost proportion.
- Historic buildings may be granted alternative compliance, but never exemption from life safety.
Maintenance duties
- The owner must keep the building and its systems in safe working condition between permits - egress paths clear, fire protection maintained, structural elements sound.
- Periodic inspection and testing requirements (alarms, sprinklers, elevators, facades in some jurisdictions) are maintenance obligations, not one-time approvals.
Unsafe structures
- Grounds typically include structural hazard, fire hazard, inadequate egress, unsanitary conditions, or general unfitness for occupancy.
- Process: inspect and document, serve written notice on the owner and interested parties, hold a hearing, then issue an order to repair, vacate, secure, or demolish.
- If the owner fails to comply, the jurisdiction may abate and place a lien for costs.
- Emergency action is permitted when danger is imminent, but the file must state the factual basis, and post-departure notice and hearing must still follow.
Worked example
After a storm, a parapet is cracked and leaning over a public sidewalk. The official may order immediate barricading and emergency stabilization, then serve notice and schedule the hearing within the statutory period before ordering demolition. Skipping notice is defensible only if the collapse risk is genuinely imminent - and the record must say why.
Traps
- Equating unsafe with cosmetic or cosmetic-plus substandard conditions.
- Failing to document the emergency justification.
- Assuming a certificate of occupancy excuses later maintenance failures.
