California regulations require specific fixture counts based on occupancy. We ensure your restrooms meet current codes during renovations or tenant improvements. ADA upgrades often qualify for tax credits while avoiding costly discrimination lawsuits. We handle permits and inspections for complete compliance.
What plumbing issues commonly affect retail and office spaces?
Common problems in Fontana retail and office buildings include constantly running toilets wasting water, clogged restroom drains from paper products, failed flush valves on commercial toilets, leaking faucets annoying customers, and water heaters failing without warning.
