# Historic Preservation Law Summary

Generates a jurisdiction-aware legal summary of historic preservation statutes, cases, and regulatory frameworks. Not legal advice — informational analysis only.

## Prerequisites

Gather before starting:

1. **Jurisdiction scope** — federal, specific state(s), and/or locality(ies)
2. **Audience** — developer, agency, advocate, counsel, or internal memo
3. **Focus topics** — designation, takings, enforcement, incentives, zoning, environmental review
4. **Sources** — uploaded materials, known ordinances, or request to locate authorities

## Quick Start

1. Confirm jurisdiction and focus topics with user
2. Build the Authority Map table (federal → state → local)
3. Populate Thematic Analysis for each in-scope topic
4. Draft Case Digest with 5–12 cases across court levels
5. Produce Procedure Checklist for the target jurisdiction
6. Flag open questions, splits, and missing sources

## Output Structure

### 1. Scope Header

State jurisdictions covered, coverage period, and source list.

### 2. Executive Overview

4–8 bullets on core principles and practical effects.

### 3. Authority Map

| Level | Authority | Citation | Core Function | Notes |
|-------|-----------|----------|---------------|-------|
| Federal | National Historic Preservation Act | [VERIFY] | Identification and review framework | Section 106 process |
| Federal | Tax incentive statute(s) | [VERIFY] | Credits/deductions | Eligibility triggers |
| State | State preservation statute | [VERIFY] | Enables/sets standards | Preemption or delegation |
| Local | Landmark ordinance | [VERIFY] | Designation + review | Demolition/alterations |

### 4. Thematic Analysis

| Topic | Rule/Standard | Leading Authority | Practical Implication |
|-------|---------------|-------------------|----------------------|
| Designation criteria | Historic significance criteria | Local ordinance; state statute | Landmarking threshold |
| Alteration/demolition review | Certificate of appropriateness | Local ordinance | Agency discretion scope |
| Takings limits | Regulatory takings framework | *Penn Central v. NYC*, 438 U.S. 104 (1978) | Balancing test constraints |
| Economic hardship | Hardship standard and proof | Ordinance/case law | Basis for relief |
| Enforcement | Injunctions, penalties, permits | Ordinance/statute | Compliance leverage |
| Incentives | Credits/grants | Federal/state programs | Offsets compliance cost |
| Zoning overlap | Zoning vs. preservation approvals | Local code | Sequencing risks |
| Environmental review | NEPA/state equivalents | [VERIFY] | Additional review layer |

### 5. Case Digest

Include 5–12 cases with parentheticals:

| Case | Court/Year | Issue | Holding | Takeaway |
|------|------------|-------|---------|----------|
| *Penn Central v. NYC* | U.S. 1978 | Landmark restrictions as takings | No taking under multi-factor test | Foundation for takings analysis |

### 6. Procedure Checklist

For the target jurisdiction:

- [ ] Identify applicable designation criteria
- [ ] Confirm notice and hearing requirements
- [ ] Document administrative record standards
- [ ] Map appeal routes and timelines
- [ ] Verify permit sequencing with zoning/building

### 7. Evidentiary Standards

Summarize how agencies/courts assess: historical significance, architectural integrity, economic hardship, and alternatives analysis.

### 8. Jurisdiction Variations

Compare state/local differences. Note preemption, delegation, and home-rule impacts.

### 9. Open Questions and Splits

Flag unresolved issues, circuit splits, and items needing updated research.

### 10. Forward-Looking Trends

Note emerging categories (mid-century, cultural sites), climate/adaptation pressures, and pending legislation.

## Pitfalls

- **Conflating levels** — always separate federal, state, and local rules
- **Missing ordinance text** — state the gap explicitly and request it from the user
- **Advocacy tone** — summarize holdings neutrally
- **Uncited assertions** — use Bluebook citations for every legal claim; mark uncertain authority with `[VERIFY]`
- **Procedural traps** — flag jurisdiction-specific notice, appeal, and record requirements
- **Constitutional constraints** — always note takings and due process limits on preservation restrictions
