“The most important document in any construction project isn't the permit — it's the contract. A vague contract with a scope defined as 'as per plans' is not sufficient protection for a homeowner. The contract should specify: payment schedule tied to milestones, allowances for specified items, exclusions list, change order threshold, and dispute resolution process.”
Always ask for a contractor's license verification at CSLB.ca.gov before signing any contract. A B-General Building Contractor license covers structural work; specialty work (electrical, plumbing, HVAC, roofing) requires separate C-license contractors on the team. Verify that any subcontractors on your project also have current CSLB licenses.

Permit requirements depend on the specific scope of work. Most structural, electrical, plumbing, and mechanical work in Los Angeles requires LADBS permits regardless of project size. Your contractor should verify permit requirements for your specific project and pull all required permits before work begins.

Design-Build Portfolio
Simple floor tile in dry areas (entry, laundry) is a reasonable DIY project. Shower tile, large-format tile, and natural stone should be professionally installed. The learning curve is steep and mistakes are expensive to fix.
DIY saves $5-$15/sqft on labor. For a 100 sqft bathroom floor, that is $500-$1,500 in savings. However, you need to rent a tile saw ($50-$100/day) and buy consumables (thin-set, grout, spacers, leveling clips).
Achieving flat, level tile with consistent grout lines. Without a leveling system, DIYers typically have visible lippage between tiles. Cutting tiles for outlets, corners, and plumbing penetrations is also challenging without experience.
No. Tile replacement is a cosmetic change that does not require LADBS permits. However, if you are tiling a shower and need to address waterproofing (Kerdi, RedGard), the underlying plumbing work may require permits.
