Frequently Asked Questions
Does Houston have zoning?
No. Houston is the largest US city without a traditional zoning code. Houston voters rejected zoning in 1948, 1962, and 1993. Land use is regulated by private deed restrictions (which cover about 45% of the city), Houston's Development Code (which sets setbacks, parking, and lot size standards), and state/federal regulations. In areas without deed restrictions, almost any use is theoretically allowed.
Can I build an ADU or secondary unit in Houston?
Yes. Because Houston has no zoning, there is no zoning prohibition on ADUs. You need a building permit from the Houston Permitting Center and must comply with setback requirements (10 ft from street) and building code. The main restriction to check is private deed restrictions in your subdivision — roughly 45% of Houston has deed restrictions that may limit additional dwelling units. Search Harris County Clerk records to find your deed restrictions.
How do I find out if my Houston property has deed restrictions?
Search the Harris County Clerk's official records at hcresearch.harriscountytx.gov or in person at 201 Caroline St, Houston. Deed restrictions are filed as legal documents and recorded against the property. They typically appear in your subdivision's original plat filing. Your title company and real estate attorney can also search for restrictions.
Does Houston require permits for construction projects?
Yes. Despite having no zoning, Houston does require building permits for construction through the Houston Permitting Center. All new construction, additions, and renovations require permits. However, unlike zoning cities, Houston's permits review only building code compliance (structural safety, electrical, plumbing) — not land use compatibility with neighbors.
Are there short-term rental (Airbnb) rules in Houston?
Yes. Houston now requires a City of Houston Certificate of Registration for every short-term rental (a stay of fewer than 30 consecutive days) operating within city limits. The requirement was established by Ordinance No. 2025-322 (adopted April 16, 2025; Chapter 28, Article XXIII) and takes effect January 1, 2026, with the city accepting registration applications beginning August 1, 2025. Texas and Houston Hotel Occupancy Taxes (approximately 13% combined) also apply and must be remitted — platforms like Airbnb typically collect and remit the tax on behalf of hosts. Deed restrictions in your subdivision may still prohibit short-term rentals, so check your deed restrictions before listing.
What should I know about building near a Houston creek or bayou?
Houston has significant flood risk — approximately one-third of Harris County flooded during Hurricane Harvey (2017). FEMA floodplain maps designate many Houston properties as Special Flood Hazard Areas (SFHAs). New construction in SFHAs must be elevated above base flood elevation. Post-Harvey drainage rules require managing the first 1.5 inches of rainfall on-site for any new development. Check FEMA's Flood Map Service Center for your property's flood zone status.
