Grandfathered property rights in Texas let you keep using your land the way you lawfully used it before a zoning change, and let you keep building a project under the rules that applied when you first filed for a permit. The first protection, called a nonconforming use, comes from Section 211.019 of the Texas Local Government Code and stops a city from forcing you to end a lawful, pre-existing use just because the ordinance changed.1State of Texas. Texas Local Government Code 211.019 – Nonconforming Land Use The second, under Chapter 245, locks in the regulations that were in effect when a development application was filed. They cover different situations and follow different rules, and both have real limits.
How Nonconforming Use Rights Work
To claim a nonconforming use, you have to show two things: the use was lawful when it started, and it has continued without significant interruption. A use that was illegal under the old rules does not become grandfathered just because a new ordinance passes. The use must have been in regular operation on the date the new regulation took effect.
The burden of proof is on the property owner, and documentation is everything. Helpful evidence includes historical deeds describing the property’s use, permits issued before the new regulation, financial records like utility bills or tax statements showing commercial activity, and dated photographs or aerial images. The stronger the paper trail, the better your position.
Most Texas municipalities require you to apply for a formal determination through the planning or building department. You submit an application with your supporting evidence, the city reviews it, and it issues a written decision. Sometimes that decision takes the form of a certificate of occupancy marked “nonconforming.” Fees vary by city, so check with your local planning office before filing.
Vested Rights for Projects Already in the Permit Pipeline
Chapter 245 covers a different scenario: development projects that were already moving through the permit process when the regulations shifted. Under Chapter 245, a regulatory agency must evaluate your permit application based on the rules in effect when you first filed it, not the rules the city adopted later.2State of Texas. Texas Local Government Code 245.002 – Uniformity of Requirements
Your rights vest the moment you file an original application or development plan that gives the regulatory agency fair notice of the project and the type of permit you need. If your project requires a series of permits, the rules in effect when you filed for the first permit govern every later permit in the series, and all permits for a single project are treated as one series.2State of Texas. Texas Local Government Code 245.002 – Uniformity of Requirements
Chapter 245 does not cover everything. Exempt categories include uniform building, fire, or plumbing codes adopted from a recognized national code organization; regulations for sexually oriented businesses; ordinances affecting colonias; fees imposed with development permits; and regulations enacted to prevent imminent destruction of property or injury from flooding within a federally established flood plain.3State of Texas. Texas Local Government Code 245.004 – Exemptions Building safety codes in particular are exempt once a permit is at least two years old, so a vested project can still be pulled onto updated safety standards.
What You Can and Cannot Do With a Grandfathered Use
A grandfathered right is specific to the exact use that existed when the new ordinance took effect. You can continue that use. You cannot expand it into something different. A grandfathered residential garage cannot be turned into an auto repair shop. A small retail store that violates a new setback rule can keep operating, but the owner cannot build an addition or tear the building down and rebuild it in the same nonconforming footprint.
Routine maintenance and repairs are fine. Fix the roof, replace windows, keep the property in good condition. What you cannot do is substantially enlarge the structure or increase the intensity of the nonconforming use. Most city ordinances draw this line explicitly. Where exactly a city draws it between “repair” and “expansion” is a common source of disputes, so when a project goes beyond simple upkeep, get written confirmation from your local planning office before starting work.
How You Can Lose the Right
Grandfathered rights are not permanent. They can end through abandonment, destruction of the structure, or municipal action.
Abandonment
If you stop a nonconforming use for long enough, the city can treat it as abandoned. Abandonment generally requires both an intent to stop the use and an actual period of inactivity. Closing a business temporarily for renovations is not abandonment. Converting the property to a conforming use and operating it that way for an extended period signals clear intent to give up the nonconforming right. Many Texas cities set specific timelines. Some ordinances treat a nonconforming use as abandoned after six months of inactivity, but the exact period varies by municipality.
Destruction
When a nonconforming structure is destroyed or severely damaged, the right to rebuild it in its nonconforming state may be lost. City ordinances typically tie the threshold to the structure’s appraised value. If damage exceeds that threshold, you have to rebuild to current code. Some Texas municipalities set the threshold at 75% of the appraised tax value above the foundation, with a requirement that any permitted rebuilding be completed within 12 months of the damage. Others use different numbers. Check your city’s zoning ordinance for the standard that applies, because this is the kind of detail that can decide whether your investment survives a storm.
Municipal Action
Under Section 211.019, a city generally cannot force you to stop a nonconforming use outright.1State of Texas. Texas Local Government Code 211.019 – Nonconforming Land Use Some municipalities historically used “amortization,” which sets a deadline for the owner to wind down the nonconforming use. The legal validity of forced amortization in Texas has been contested in the courts, and the trend has been toward requiring compensation or a voluntary agreement rather than simply ordering an owner to stop. If your city tries to eliminate your nonconforming use, consult a land use attorney about what protections apply to your specific situation.
Appealing a City Decision
If a city official denies your nonconforming use claim or makes another zoning decision you disagree with, you can appeal to the local Board of Adjustment. Texas law authorizes municipalities to appoint a Board of Adjustment with at least five members, and the board has the power to hear appeals alleging error in any order, requirement, or decision made by an administrative official enforcing the zoning ordinance.4State of Texas. Texas Local Government Code 211.009 – Authority of Board The board can reverse, affirm, or modify the original decision.
The board can also grant a variance in specific cases where strict enforcement would cause unnecessary hardship and the variance would not harm the public interest. Factors the board can weigh include whether the cost of compliance exceeds 50% of the structure’s appraised value, whether compliance would cause the lot to lose at least 25% of its buildable area, and whether the municipality itself considers the structure nonconforming.4State of Texas. Texas Local Government Code 211.009 – Authority of Board A 75% vote of the board is required to reverse an administrative decision or grant a variance.5State of Texas. Texas Local Government Code 211.008 – Board of Adjustment
If the Board of Adjustment rules against you, you can take the matter to court. A person aggrieved by a board decision may file a verified petition in district court, county court, or county court at law, stating that the board’s decision is illegal and specifying the grounds. You have only 10 days from the date the decision is filed in the board’s office to file your petition, so act fast if you intend to appeal.6State of Texas. Texas Local Government Code 211.011 – Judicial Review of Board Decision
Buying or Selling Property With a Nonconforming Use
Grandfathered rights attach to the property, not the person. When property with a nonconforming use is sold, the new owner inherits the same right to continue that use, along with the same restrictions. The buyer cannot expand or alter the nonconforming use any more than the seller could.
If you are buying property with claimed nonconforming status, verify it before closing. Get a formal letter or certificate of nonconforming use from the local planning department confirming the property’s status. The sale contract should address the nonconforming use explicitly, including what it covers and any known limitations. Sellers should be ready to hand over whatever historical documentation they have, because once the sale closes, the new owner carries the burden of proof if the city ever challenges the use. Finding out after closing that the nonconforming rights are weaker than expected, or never existed at all, is an expensive problem with limited remedies.
