What Claremont regulates

The city says all residents are required to maintain their properties and structures so they do not create a visual nuisance for neighbors. Its Community Improvement page lists the topics it enforces, and several affect homeowners directly.

Property maintenance and landscaping

Residential and commercial landscaping must be kept up, and eyesores in rear yards that are visible from adjacent properties, including weeds and overgrown vegetation that create fire hazards, are covered. Swimming pools and spas must be kept free of algae and conditions that encourage mosquito breeding, and pool fences and gates must provide a secure barrier.

Vehicles and parking

Inoperable vehicles, meaning vehicles that are unlicensed, unregistered or missing parts needed to operate legally, must be stored out of view of the street and neighboring properties.

Boats, campers, trailers and motor homes must be kept in a garage or in an interior side or rear yard enclosed by a solid fence or wall at least five feet high. Temporary RV parking permits are available for up to 14 days per calendar year.

Residential vehicles must be parked on paved driveways or approved areas, not on lawns or sidewalks, and overnight street parking is prohibited for longer than one hour between 2 a.m. and 6 a.m.

Noise, lighting and signs

Moderate noise is allowed from 7 a.m. to 10 p.m., with stricter standards from 10 p.m. to 7 a.m. Property maintenance noise is limited to 7 a.m. to 8 p.m. Monday through Saturday and 9 a.m. to 8 p.m. on Sunday, and construction noise to 7 a.m. to 8 p.m. Monday through Saturday.

Outdoor lights must be shielded and directed downward. Temporary signs have size limits, and permanent signs require staff or Architectural Commission approval.

Animals, garage sales and abandoned property

The city limits the number of adult dogs or cats to three per residence, regulates dangerous or exotic animals, and limits garage or yard sales to three consecutive days twice a year. Its Abandoned Property Program requires mortgage lenders to inspect defaulted properties, register vacant ones with the city, and secure and maintain them. Non-local lenders must hire a local company for weekly inspections and post a 24-hour contact number.

How to report or resolve an issue

Call the Community Improvement office at (909) 399-5499 or visit the Community Development counter at City Hall. Graffiti goes to the 24-hour hotline at (909) 445-7825. For juvenile graffiti vandalism, the city says it seeks financial restitution from parents and requires vandals to remove the graffiti. The city’s page does not publish a fine schedule or notice timelines, so ask the office directly what applies to your address.

The city also notes that its housing rehabilitation program may, in some cases, help homeowners with improvements that eliminate blight and correct building and health code violations.

Code issues and selling a Claremont house

Open violations can slow a listing because buyers’ lenders and inspectors notice unmaintained yards, stored vehicles and unfinished work. California sellers must disclose known problems on the transfer disclosure paperwork, and our guide to selling as-is with unpermitted work explains what that covers. If the violation involves construction, see our Claremont building permits guide.

• Ask the Community Improvement office whether any case is open on your address.
• Fix quick items first: remove stored inoperable vehicles, trim overgrown vegetation, secure the pool.
• Keep notices, photos and correspondence showing what was resolved.
• For larger problems, compare the cost of repairs with selling as-is for cash.

How to sell a house in Claremont

1. Find out whether the city has any open case on the property.
2. Gather any notices and records of work already done.
3. Request a no-obligation cash offer for the house as it stands.
4. Choose your closing date.
5. Close with no repairs, cleanup or showings required.
