Cedar Park FAQ
Can I park a tiny home on wheels and live in it on my Cedar Park lot?
No. Cedar Park classifies tiny homes on wheels as recreational vehicles, and RVs may not be occupied as a permanent or long-term residence on a residential lot. RV parking/storage rules in Chapter 11 limit how and where the unit may be kept on the property.
Is there a minimum size for a house in Cedar Park?
Yes. Dwelling units must be a minimum of 450 square feet of living area under Chapter 11's residential design standards. A site-built or modular tiny home on a permanent foundation must meet that floor and comply with the full International Residential Code as adopted by the city.
Can I put a tiny home in my backyard as a guest house?
Only as an accessory dwelling unit (ADU), only in Development Reserve, Estate Reserve, Estate Residential, or Suburban Residential districts, only with a conditional use approval, only in the rear yard, and only at 400–600 sq ft livable (650 gross max). It cannot be a detached garage conversion and cannot be sold or leased separately from the main house.
