Frequently Asked Questions

What are the exact CRMLS photo requirements?

CRMLS requires JPEG format, 4:3 aspect ratio, minimum 1024x768 (recommended 2048x1365), under 15MB file size, sRGB color profile, maximum 50 photos per listing. BuildMyListing automatically formats all photos to these exact specifications.

Do different California MLSs have different photo requirements?

Yes. CRMLS requires 4:3 ratio, CARETS allows flexible ratios but prefers 1024x768+, MetroList recommends 1600x1200. BuildMyListing creates versions optimized for each MLS system.

Can I upload iPhone HEIC photos to California MLSs?

Most MLSs only accept JPEG format. BuildMyListing automatically converts HEIC, RAW, PNG, and other formats to JPEG while preserving quality and meeting MLS requirements.

What happens if my photos are too large for MLS?

MLSs reject oversized files. BuildMyListing compresses photos under size limits (15MB for CRMLS, 10MB for CARETS) while maintaining visual quality through smart compression algorithms.

How many photos can I upload to California MLSs?

Limits vary: CRMLS allows 50 photos, CARETS allows 25, MetroList allows 40. BuildMyListing tracks limits for each MLS and helps you select the best photos for each system.

Do I need AB 723 compliance for basic photo enhancement?

Basic adjustments (exposure, color, straightening) are exempt from AB 723 disclosure. Virtual staging, sky replacement, and object removal require disclosure. BuildMyListing automatically tracks which edits need disclosure.

Can I use the same photos for multiple California MLSs?

Yes, but each MLS has different technical requirements. BuildMyListing creates optimized versions for each MLS system so you can use the same source photos across multiple territories.

What aspect ratio should I use for MLS photos?

CRMLS requires 4:3 aspect ratio. Other California MLSs are more flexible but 4:3 works universally. BuildMyListing automatically crops to optimal ratios while preserving important visual elements.

Why do my professional photos get rejected by MLS?

Common issues: wrong color profile (Adobe RGB vs sRGB), large file sizes, incorrect dimensions, or TIFF/RAW formats. BuildMyListing handles all technical conversion automatically.

How do I order photos for best MLS presentation?

Start with exterior/main view, then living areas, kitchen, master suite, additional rooms, and outdoor spaces. BuildMyListing provides photo ordering guidance and can suggest optimal sequence based on room type detection.
