How Houston Handles Tree Protection: A Practical Guide
Houston maintains 186 local ordinances across all categories, and 3 of those deal specifically with tree protection. Here is a breakdown of what the city actually requires, what is prohibited, and where Houston falls on the strict-to-permissive spectrum compared to other cities.
Heritage & Protected Trees
Houston City Council may designate a tree as historically or arboriculturally significant by motion, but only if the property owner applies; once designated, the tree becomes a protected tree under Chapter 33's removal and replacement rules.
Key details: Who may designate: City council, by motion. Owner consent: Application must be made or joined by owner. Review body: Historical/Archaeological Commission or Parks director. Denial cooldown: 3 years before re-application. Violation penalty: Up to $500 fine.
Once designated, removing the tree without following Sec. 33-105's replacement and notice rules is a Code violation punishable by a fine up to $500 per Sec. 33-109.
Parkway Planting
New and expanded commercial or multifamily buildings in Houston must plant street trees in the parkway strip along public streets, spaced and set back from the curb under Chapter 33's landscape standards: single-family homes are exempt.
Key details: Trigger: New/expanded nonresidential or multifamily buildings. Planting formula: 1 tree per 30 linear feet frontage. Curb setback: At least 3 feet from curb. Tree spacing: No closer than 20 feet apart. Species: Must be on city street tree list.
No final certificate of occupancy issues until required parkway trees are installed per the approved landscape plan (Sec. 33-132); owners may instead post a bond or assigned certificate of deposit to get a conditional C.O. (Sec. 33-133).
Protected Tree Species
Houston, which has no zoning, protects trees within streets and parkways under Chapter 33, Article VI. Removing a covered street tree requires 20 days' written notice and a replacement requirement met by replanting inch-for-inch or paying $225 to $500 per caliper inch into the city tree fund.
Key details: Governing law: Chapter 33, Article VI, §33-160. Covered tree: 20+ caliper inches, or 1.5" street-list. Replacement: 1 caliper inch per inch removed. In-lieu fee: $225/$375/$500 per caliper inch. Notice: Written, 20 days before removal.
Removing a covered tree without permission is an offense punishable by a fine of up to $500, with each removed tree a separate offense; the city can also sue to recover the tree's value. Enforced by Houston Parks and Recreation.
The Bottom Line
Houston's tree protection rules are a mixed bag. Some areas are strict, others are relaxed, and the details matter. The best approach is to check the specific rule that applies to your situation rather than assuming Houston is broadly strict or permissive.
These rules come from Houston's publicly available municipal code. For complete penalty schedules, exemption details, and answers to common questions, see the individual ordinance pages throughout this guide.
