Call the permit counter before you upload anything, or the online submittal goes nowhere.
South Pasadena asks that you contact the city permit counter to file a permit application and arrange payment of plan review fees before submitting plans to the online portal. Uploading first and waiting is a common way to lose time here, because the application has to exist before the plans have anywhere to land.
The city sits at the western end of the San Gabriel Valley, north of El Sereno, east of the Arroyo Seco and south of Pasadena. There are 11,146 housing units at nearly 3,300 per square mile, 95.2 percent occupied, and 55.7 percent of the occupied ones are rented.
Older established housing means decks and balconies that have often been recoated more than once, and layered coatings that no longer bond are a common find once we open one up. Each layer was a reasonable decision at the time. Together they make a surface that splits at an interface nobody can see.
The way to settle it is a test cut. Cut through the build-up, look at how many layers there are and whether they are still stuck to each other and to the substrate, and read moisture at the wall line. That is a short piece of work and it decides the entire scope.
With more than half the stock rented, a large share of the work is shared surfaces: exterior stairs, second floor landings and walkways serving several doors. Those get a traffic rated build and a schedule that keeps residents moving through the job.

Contact the City Permit Counter first to file the permit application and arrange payment of the plan review fees, then submit plans through the online portal. Plans uploaded before the application exists have nowhere to go. We handle it in that sequence.
It usually hurts. Layers that no longer bond to each other move independently and split at the interface, so the newest coat fails early regardless of quality. A test cut shows how many layers there are and what is still holding.
Manageable if it is planned. We phase the work so every unit keeps a route to a stair, close only the section being torn out, and time the stages that need cure where they interfere least with residents coming and going.
A professionally installed waterproofing system typically lasts many years. Capital Deck & Stair backs most projects with an 8-year warranty on workmanship, and proper maintenance can extend the life well beyond that.
Cost depends on the surface size, condition, and the coating system required. We provide a clear, itemized quote after a free on-site inspection, with no obligation and no pressure.
Most residential decks, balconies, and stairs take about a week from start to finish, depending on prep, repairs, and weather. We give you a firm timeline before work begins.
