PERMIT PROCESS

WHAT PERMITS DO I NEED? ADU construction only requires a building permit. When submitting your building permit application, you must include the following information with your application: • Proof of ownership and residency • A site plan • An engineered foundation • Building plans in compliance with the 2015 International Residential Building Code (IRC). HOW DO I APPLY? You may apply for a building permit online by visiting www. mygovernmentonline.org . This website will allow you to apply, upload necessary paperwork, pay, schedule inspections, and track the progress of your project. If you have any questions during the process, you can email permitinfo@sanmarcostx.gov or call (512)805-2630 for assistance. DO I NEED A CONTRACTOR? A licensed contractor is encouraged but not required when your property is homesteaded. Compliance with all applicable building codes will be verified during plan review and on-site inspections by a City building inspector. HOW MUCH DOES A PERMIT COST? The fee for a residential building permit is 46 cents per square foot. In order to encourage property owners to improve their property, the City of San Marcos waives all permit fees for homesteaded properties with completion of a homeowner’s affidavit when the homeowner is applying for a permit.
