Planning a home project in St. Louis means working with two layers of rules: Missouri's contractor licensing framework and St. Louis's own permit requirements. This guide covers both, plus how St. Louis's housing stock and local conditions shape the projects homeowners here hire for.
St. Louis is home to roughly ~280,000 residents. Fair Price Pros currently accepts HVAC requests; for other trades, use this guide to plan your project and compare written proposals independently.
Permits in St. Louis
Building permits for St. Louis are issued through the city's permit office, linked in the sources on this page. Most work beyond cosmetic finishes — structural changes, electrical circuits, plumbing, HVAC replacements, roofing, fences, and larger landscaping work — requires a permit and inspection.
The contractor should pull the permit in their own name and schedule inspections. Permit fees and processing times are set locally, so confirm current requirements with the permit office before signing a contract, and be cautious of any contractor who suggests skipping a required permit.
Verifying contractors who work here
Missouri does not license general contractors statewide — St. Louis, Kansas City, and other municipalities run their own contractor licensing. Electricians and plumbers are licensed locally in the major metros and by the state in some categories. Always check the local rule for the city where the work happens.
Before hiring anyone in St. Louis, verify the license or registration through the official state lookup linked above, confirm insurance directly with the carrier, and ask for recent local references on similar projects.
Local conditions that shape St. Louis projects
St. Louis's historic brick housing stock includes some of the nation's finest 19th-century neighborhoods, with historic review in many areas. The city and county are separate jurisdictions with separate rules.
Hot humid summers, cold winters, and severe storms including tornadoes shape Missouri projects. Hail damage drives roofing demand, and basement waterproofing is a recurring need.
Housing in St. Louis
Housing ranges from historic St. Louis brick homes to post-war suburbs. Basements are common, and older urban homes frequently have aging systems and lead paint.
For homes built before 1978, assume painted surfaces may contain lead until tested — federal rules require contractors disturbing painted surfaces to be lead-safe certified. Older homes may also have aging wiring, galvanized plumbing, or unpermitted past work that affects new projects.
Hiring smart: quotes, contracts, and payments
Get at least two or three written, itemized quotes. The contract should name the scope, price, milestone-based payment schedule, start and completion dates, change-order process, and warranty terms. Tie payments to completed work and never pay in full up front.
Be wary of door-to-door solicitation after storms, pressure to sign immediately, large cash deposit demands, and contractors who cannot provide a verifiable license, insurance, and local references.
