Costs like engineering and permitting can become disproportionately high for mid-size projects.Height and Density: Focus on areas where zoning allows for verticality and density.

Can you take it to the city to get it permitted?

As far as permits and renovations and ADU additions?

I agree, I would be very careful doing anything that is not permitted or allowed based on the zoning. 

After reviewing the latest ordinances, reports, and city guidelines, here’s a summary of my findings as of 11/18/2024:Key FindingsPermit Types and Fees:Type 1 (Owner-Occupied): $300 for 3 years.Type 2 (Non-Owner-Occupied): $450 for 3 years.Density caps apply to Type 2 permits (12.5% of block face).Enforcement:3 violations in 3 years lead to permit revocation.Fines up to $500/day for violations.Hotel Occupancy Tax (HOT):City: 9%, County: 1.75%, State: 6%.Platforms like Airbnb and VRBO will remit directly to the city starting Feb 2025.Platform Obligations:STRs must have valid permits; unpermitted properties will be removed by platforms like Airbnb.Special Exceptions for Density Limits:Require approval by the Board of Adjustment (BOA).Zip Code BreakdownI focused on these 11 zip codes:Under San Antonio Rules:78205, 78204, 78215, 78210, 78212, 78245, 78258Independent Municipalities (Separate Rules):Alamo Heights (78209)Leon Valley (78238)Helotes (78023)Next Steps:Research density caps and zoning in specific zip codes.Dive into independent municipality rules for Alamo Heights, Leon Valley, and Helotes.Evaluate market maturity and income potential using tools like AirDNA.If anyone has experience operating STRs in San Antonio or these specific zip codes, I’d love to hear your insights, especially about density limits, enforcement trends, or community sentiment.Thanks in advance!

All you're doing is finishing space and you should be able to go through normal permitting processes to get that done.  

Go into the new member introductions forum and watch for the same few people who say the same basic message every time someone new comes on the site.

Just keep thorough records of your expenses—materials, labor, permits, etc.

Part of how the municipalities get you is pulling permits.
